Product Description
We are 1 of the leading manufacturer of planetary gearboxes through powder metallurgy. A gearbox is a power transmission device to produce high torque by reducing the drive speed or increase the drive speed the other way. Planetary gearbox consisting 3 components: sun gear, planet gear and ring gear . A Sun gear is a gearwheel in a planetary gear system, that rotates around its own axis and has other gears (planet gears) that rotate around it. Much like the Sun and planets in our solar system. The amount of planetary gears in a gearbox varies based on the gear ratio. Most planetary gearboxes have from 2 to 5 planet gears.
When looking at planetary gears, the strength of the gearbox is usually determined by the size of the sun gear. Larger sun gears will allow for higher torque values. The planet carrier,Its objective is to hold up to gears of the same size, which mesh with the sun gear.

Powder metallurgy is a metal working process in which finely-powdered metal is mixed with binder material to create a”feedstock” that is then shaped and solidified using injection molding.The ability to combine several operations into 1 process ensures MIM is successful in saving lead times as well as costs, providing significant benefits to manufacturers. The metal injection molding process might be a green technology due to the significant reduction in wastage compared to “traditional” manufacturing methods.
MIM can produce parts where it is difficult, or even impossible, to efficiently manufacture an item through other means of fabrication. Increased costs for traditional manufacturing methods inherent to part complexity, such as internal/external threads, miniaturization, or identity marking, typically do not increase the cost in a MIM operation due to the flexibility of injection molding.
The window of economic advantage in metal injection molded parts lies in complexity and volume for small-size parts. MIM materials are comparable to metal formed by competing methods, and final products are used in a broad range of industrial, commercial, medical, dental, firearms, aerospace, and automotive applications. Dimensional tolerances of ±0.3% are common and machining is required for closer tolerances .
MIM technology has found increased applications in the commercial world – from home appliances to watches, automobiles to aerospace, and medical to orthodontics.
The advantages of metal injection molding for metal fabrications :
- Highest degree of design freedom for complex shapes and geometries
- Provides practical economic solutions to increasingly stringent material and product design requirements
- Functional integration of various features, such as lateral drillings, interior and exterior threads and gear teeth.

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.
