Maintenance of the gearbox of the dual-screw extruder
1. The gear box of the dual-screw extruder should be well-ventilated, and the working environment temperature should be within the range of 5-35 °C.
2. Always check the oil quantity of the gear lubricating oil in the box to ensure that the transmission parts in the box are well lubricated.
3. Pay attention to check the bearing parts of the box frequently. The oil temperature of the oil tank of the transmission box should not exceed 70 ºC during operation.
4. The newly put into use gearbox needs to replace the lubricating oil after 250 hours of operation. The oil change time depends on the state of the oil. It is recommended to replace it after 4000-8000 hours of operation or once a year.
5. The gearbox of the dual-screw extruder needs to be regularly maintained and inspected once a year
Operating Process
1. The gear on the input shaft is driven by the motor and starts to rotate.
2. The rotating input gear meshes with other gears inside the gearbox, transmitting power.
3. Different-sized gears within the gearbox are combined to form a gear train. Through continuous meshing and rotation, the high-speed, low-torque power from the input shaft gradually converts into low-speed, high-torque output.
4. The output shaft is connected to the last gear and transfers the output torque to the load.
5. Gear reduction gearboxes typically include lubrication and cooling systems to ensure smooth operation and prevent overheating and damage.
6. Our extruder gearbox converts high-speed, low-torque power into low-speed, high-torque output by changing the size ratios and meshing arrangements of different gears, achieving the function of speed reduction.

Planetary Gearbox Basics
If you’re in the market for a new Planetary Gearbox, you’ve come to the right place. There’s more to these mechanical wonders than just their name. Learn about Spur gears, helical gears, and various sizes. After you’ve read this article, you’ll know exactly what to look for when shopping for a new one. And you’ll also be able to avoid common mistakes made by amateur mechanics.
Wheel drive planetary gearboxes
Planetary gearboxes have numerous benefits over conventional gearboxes. Their compact design is advantageous for servo functions. Their lubrication is a key feature to maintain smooth operation and avoid damage to the gears. Some manufactures use CZPT to ensure proper functioning. These gearboxes have nearly three times the torque of traditional gearboxes while remaining compact and low in mass.
The planetary gears are made of three different types. Each type has an input and output shaft. The input and output shafts are usually coaxially arranged. The input and output shafts are connected to each other via a carrier. The carrier rotates with the planetary gears. The sun gear is the input gear and is typically 24 teeth in diameter. The outer gears are connected to the sun gear via rings of gears that are mounted around the sun gear.
Planetary gearboxes are also used in wheeled and tracked vehicles. They are also used in winch systems, which lift and lower loads. Typical applications include heavy machinery, such as cranes and earthmovers. Wheel drives are also widely used in municipal and agricultural vehicles, as well as material handling vehicles. The wheel drive is typically mounted directly into the wheel rim. A wheel drive may be fitted into two, three, or even four wheels.
A planetary gear set may be used in stages to provide different transmission rates. In order to choose the right gearbox for your application, consider the torque, backlash, and ratio you need. Then, consider the environment where the gearbox is used. Depending on its location, it might need to be protected from weather, water, and other elements. You can find a wide range of different sizes in the market.
Spur gears
There are two basic types of gearheads: planetary and spur gearheads. Each has its advantages and disadvantages depending on the application. This article will discuss the differences between these two types of gearheads. Spur gearheads are commonly used for transmission applications, while planetary gearheads are more widely used for motors. Spur gearheads are less expensive to produce than planetary gearheads, and they are more flexible in design.
There are many different types of spur gears. Among them, a 5:1 spur gear drive ratio means that the sun gear must rotate five times per revolution of the output carrier. The desired number of teeth is 24. In metric systems, the spur gears are referred to as mm and the moon gears as modules. Spur gears are used in many different types of applications, including automotive and agricultural machinery.
A planetary geartrain is a combination of ring and spur gears, which mesh with each other. There are two kinds of planetary geartrains: simple planetary gears and compound planetary gears. Spur gears are the most common type, with a sun gear and ring gear on either side of the sun. Simple planetary gears feature a single sun and ring gear, while compound planetary gears use multiple planets.
A planetary gearbox consists of two or more outer gears, which are arranged to rotate around the sun. The outer ring gear meshes with all of the planets in our solar system, while the sun gear rotates around the ring gear. Because of this, planetary gearboxes are very efficient even at low speeds. Their compact design makes them a desirable choice for space-constrained applications.
Helical gears
A planetary helical gearbox has two stages, each with its own input speed. In the study of planetary helical gear dynamics, the base circle radius and full-depth involute teeth are added to the ratio of each gear. The tangential position of the planets affects the dynamic amplifications and tooth forces. The tangential position error is an important factor in understanding the dynamic behaviour of helical planetary gears.
A helical gearbox has teeth oriented at an angle to the shaft, making them a better choice than spur gears. Helical gears also operate smoothly and quietly, while spur gears generate a thrust load during operation. Helical gears are also used in enclosed gear drives. They are the most common type of planetary gearbox. However, they can be expensive to produce. Whether you choose to use a helical or spur gearbox depends on the type of gearbox you need.
When choosing a planetary gear, it is important to understand the helix angle of the gear. The helix angle affects the way the planetary gears mesh, but does not change the fundamentals of planetary phasing. In each mesh, axial forces are introduced, which can either cancel or reinforce. The same applies to torques. So, if the ring gear is positioned at an angle of zero, helical gears will increase the axial forces.
The number of teeth on the planets is a variable parameter that must be considered in the design phase. Regardless of how many teeth are present, each planet must have a certain amount of tooth spacing to mesh properly with the ring or sun. The tip diameter is usually unknown in the conceptual design stage, but the pitch diameter may be used as an initial approximation. Asymmetrical helical gears may also cause undesirable noise.
Various sizes
There are several sizes and types of planetary gearboxes. The planetary gear sets feature the sun gear, the central gear, which is usually the input shaft, and the planet gears, which are the outer gears. A carrier connects the planet gears to the output shaft. The primary and secondary features of the planetary gearbox are important factors to consider. Besides these, there are other things to consider, such as the price, delivery time, and availability around the world. Some constructors are quicker than others in responding to inquiries. While others may be able to deliver every planetary gearbox out of stock, they will cost you more money.
The load share behavior of a planetary gearbox is comparable to that of a spur or a helical gearbox. Under low loads, individual gear meshes are slightly loaded, while other components have minimal deflections. In general, load sharing behaviour is affected mostly by assembly and manufacturing deviations. In this case, the elastic deflections help balance these effects. The load-sharing behavior of a planetary gearbox improves when the load increases.
Planetary gearboxes come in different sizes. The most common size is one with two or three planets. The size and type of the gears determine the transmission rate. Planetary gear sets come in stages. This gives you multiple transmission rate choices. Some companies offer small planetary gearboxes, while others offer larger ones. For those with special applications, make sure you check the torque, backlash, and ratio.
Whether the power is large or small, the planetary gearbox should be matched to the size of the drive. Some manufacturers also offer right-angle models. These designs incorporate other gear sets, such as a worm gear stage. Right-angle designs are ideal for situations where you need to vary the output torque. When determining the size of planetary gearboxes, make sure the drive shafts are lined up.

How to Design a Forging Spur Equipment
Before you commence developing your personal spur equipment, you need to realize its principal elements. Between them are Forging, Keyway, Spline, Set screw and other sorts. Understanding the differences amongst these types of spur gears is essential for producing an informed selection. To discover much more, keep reading through. Also, never wait to make contact with me for help! Listed underneath are some valuable suggestions and tricks to style a spur gear. Ideally, they will support you design and style the spur equipment of your dreams.
Forging spur gears
Forging spur gears is one particular of the most crucial processes of automotive transmission elements. The producing procedure is complex and involves numerous methods, these kinds of as blank spheroidizing, sizzling forging, annealing, phosphating, and saponification. The materials employed for spur gears is typically 20CrMnTi. The process is concluded by implementing a ongoing by way of extrusion forming strategy with dies made for the sizing band length L and Splitting angle thickness T.
The method of forging spur gears can also use polyacetal (POM), a strong plastic generally utilized for the manufacture of gears. This substance is simple to mould and shape, and following hardening, it is really rigid and abrasion resistant. A amount of metals and alloys are employed for spur gears, like forged metal, stainless steel, and aluminum. Detailed underneath are the different varieties of supplies utilised in gear manufacturing and their advantages and negatives.
A spur gear’s tooth dimension is measured in modules, or m. Each and every quantity signifies the number of teeth in the gear. As the quantity of enamel boosts, so does its size. In standard, the greater the variety of enamel, the bigger the module is. A large module gear has a big pressure angle. It is also important to bear in mind that spur gears must have the same module as the gears they are utilised to generate.
Established screw spur gears
A modern market are not able to perform with out established screw spur gears. These gears are very effective and are broadly used in a variety of applications. Their design and style entails the calculation of pace and torque, which are the two critical elements. The MEP design, for instance, considers the changing rigidity of a tooth pair together its path. The results are used to determine the sort of spur gear essential. Listed underneath are some tips for selecting a spur equipment:
Type A. This variety of gear does not have a hub. The equipment by itself is flat with a small gap in the middle. Set screw gears are most typically utilised for light-weight apps without loads. The metallic thickness can variety from .25 mm to 3 mm. Set screw gears are also employed for huge equipment that require to be powerful and resilient. This write-up supplies an introduction to the different varieties of spur gears and how they vary from a single another.
Pin Hub. Pin hub spur gears use a set screw to protected the pin. These gears are typically connected to a shaft by dowel, spring, or roll pins. The pin is drilled to the specific diameter to fit inside of the equipment, so that it does not arrive unfastened. Pin hub spur gears have high tolerances, as the hole is not massive sufficient to totally grip the shaft. This kind of equipment is generally the most pricey of the three.
Keyway spur gears
In present day present day market, spur gear transmissions are commonly utilized to transfer power. These sorts of transmissions supply excellent performance but can be prone to electricity losses. These losses need to be approximated in the course of the style method. A essential ingredient of this examination is the calculation of the contact spot (2b) of the equipment pair. However, this worth is not always applicable to every spur gear. Listed here are some illustrations of how to calculate this location. (See Determine 2)
Spur gears are characterised by possessing teeth parallel to the shafts and axis, and a pitch line velocity of up to 25 m/s is considered higher. In addition, they are much more efficient than helical gears of the exact same dimension. In contrast to helical gears, spur gears are generally regarded as constructive gears. They are frequently employed for applications in which sound handle is not an issue. The symmetry of the spur equipment makes them specifically suited for applications where a constant speed is needed.
Aside from employing a helical spur equipment for the transmission, the gear can also have a standard tooth form. Not like helical gears, spur gears with an involute tooth sort have thick roots, which stops use from the enamel. These gears are easily created with traditional production resources. The involute condition is an best decision for little-scale creation and is 1 of the most common types of spur gears.
Spline spur gears
When taking into consideration the varieties of spur gears that are utilised, it’s critical to note the distinctions among the two. A spur equipment, also referred to as an involute equipment, generates torque and regulates pace. It really is most frequent in auto engines, but is also utilised in each day appliances. Nevertheless, one of the most substantial drawbacks of spur gears is their sounds. Due to the fact spur gears mesh only one tooth at a time, they produce a large amount of pressure and sound, producing them unsuitable for daily use.
The speak to tension distribution chart signifies the flank area of every gear tooth and the length in each the axial and profile course. A large speak to spot is positioned towards the center of the gear, which is triggered by the micro-geometry of the gear. A positive l value signifies that there is no misalignment of the spline enamel on the interface with the helix hand. The opposite is accurate for unfavorable l values.
Employing an higher certain approach, Abdul and Dean examined the forging of spur gear types. They assumed that the tooth profile would be a straight line. They also examined the non-dimensional forging strain of a spline. Spline spur gears are commonly utilised in motors, gearboxes, and drills. The energy of spur gears and splines is mainly dependent on their radii and tooth diameter.
SUS303 and SUS304 stainless metal spur gears
Stainless steel spur gears are manufactured utilizing various strategies, which depend on the materials and the application. The most widespread method used in producing them is cutting. Other procedures include rolling, casting, and forging. In addition, plastic spur gears are made by injection molding, dependent on the quantity of production essential. SUS303 and SUS304 stainless steel spur gears can be made employing a assortment of materials, which includes structural carbon steel S45C, gray forged iron FC200, nonferrous metallic C3604, engineering plastic MC901, and stainless metal.
The variances between 304 and 303 stainless metal spur gears lie in their composition. The two sorts of stainless steel share a typical style, but have varying chemical compositions. China and Japan use the letters SUS304 and SUS303, which refer to their different levels of composition. As with most sorts of stainless steel, the two different grades are created to be employed in industrial programs, these kinds of as planetary gears and spur gears.
Stainless steel spur gears
There are numerous items to look for in a stainless steel spur gear, like the diametral pitch, the quantity of enamel for each device diameter, and the angular velocity of the teeth. All of these aspects are crucial to the overall performance of a spur gear, and the proper dimensional measurements are crucial to the design and style and functionality of a spur equipment. Individuals in the business need to be familiar with the terms employed to describe spur equipment components, both to make sure clarity in production and in purchase orders.
A spur equipment is a sort of precision cylindrical gear with parallel enamel arranged in a rim. It is utilised in various purposes, this sort of as outboard motors, winches, design tools, lawn and backyard garden equipment, turbine drives, pumps, centrifuges, and a range of other devices. A spur equipment is usually created from stainless metal and has a high degree of durability. It is the most typically used sort of gear.
Stainless steel spur gears can appear in many diverse shapes and measurements. Stainless metal spur gears are typically manufactured of SUS304 or SUS303 stainless steel, which are employed for their greater machinability. These gears are then heat-taken care of with nitriding or tooth surface induction. Not like traditional gears, which need to have tooth grinding right after warmth-treating, stainless steel spur gears have a low put on price and large machinability.
