Planetary Gearbox

Planetary Gearboxes is an old mechanics fundamental that is still being used for new leading innovative technology like 3D printing, and new methods of transport. The planetary gearbox is one in which the output and input shafts are aligned. Its basic function is to transfer the maximum amount of torque with the least amount of space. The gear system consists of a reduction state, an acceleration mode, and coupling. No one knows who invented the planetary gearbox, but it has been in use since the 15th century. The planetary gear gets its name from the way it looks while it functions. There is a sun gear in the middle attached to ring gears. As the sun gear rotates, it also moves the ring gears. The sun gears are called input shafts, whereas the carrier and ring gears are called output.

行星齿轮箱的工作ratios from 1.5:1 to 12000:1. In a 3:1 system, there are three ring gears and one sun gear and is called a one-stage planetary gearbox. In ratios of above 5:1, a two-stage planetary gearbox is used. In a 3:1 system, the sun gear is very big, compared to the ring gear, and in the 10:1 system, the sun gear is much smaller than the ring gears. The ratios are in absolute integers. The planetary gearbox system is very precisely placed together, but it still creates friction due to the moving parts inside – sun gear and ring gear. These need lubrication from time to time from oil, gel, or grease. This requirement is present in most moving mechanical machines.

We are among one of the largest planetary gearbox manufacturers in China, we use premium quality raw material for manufacturing the best product for satisfactory use and durability.

There are many showcased benefits of using a gearbox like- three-fold torque compared to the normal gearbox, absolute ratios, low inertia, high efficiency, closed system, etc. The planetary gearbox has its applications in many places. It can be used to increase torque in a robot, to reduce speed in printing press rollers, for positioning, and in packaging machines to name a few.
Buying a gearbox depends on the planned use of the gearbox. There are a certain number of things to keep in mind like – torque, backlash, ratio, corrosion, resistance, noise level, delivery time, price, and availability. There might be other requirements that are different for each buyer.
A planetary gearbox is a medieval tool reincarnated in modern form. That itself says a lot about the usefulness and application of the device. It’s an efficient device for the work it performs and has stood the test of time, without getting obsolete.

Ever-Power have many years of experience in Planetary Gearboxes, we produce very high quality planetary gearboxes with very competitive prices. Planetary Gearboxes have been designed for different transmission .
The power is transmitted form the motor to sun gearboxes. The sun gearboxes drives three Planetary Gearboxes, which are contained within an internal toothed ring gearboxes. The Planetary Gearboxes are mounted on the planetary carrier. The planetary carrier is part output shaft. So when the sun gearboxes rotates, it drives the three Planetary Gearboxes inside the ring gearboxes.
As Planetary Gearboxes rotate with carries and automatically the highest torque and stiffness for a given envelope. The other significant advantages are simple and efficient lubrication and a balanced system at high speeds. The balanced planetary kinematics and the associated load sharing makes the planetary-type gearboxes truly ideal for servo applications.
Modular concept, allows us to after particularly short delivery time for gearboxes with a constantly high standard of quality whether your applications requires a reducer for motors, Let our term of engineers work for you.

There are three main components in a planetary gearbox: the sun gear, the planet gears and the ring gear. The gears are attached to the planet carrier that has teeth on the inside, which is the ring gear.

Planetary gearboxes are able to produce many different reduction ratios because of the different planet gears that revolve around the sun gear. Planetary gearboxes are constructed of heavy duty metal such as steel and are able to handle large shock loads well. However, different planetary gearboxes are designed for specific speed, load and torque capacities. The predominant use for planetary gearboxes is in motor vehicles with automatic transmissions. Unlike manual transmission, in which the operator is responsible for switching gears, automobiles that have automatic transmissions use clutches, brake bands and planetary gearboxes to change the inputs and outputs, thereby adjusting the speeds accordingly.

An automatic transmission contains two complete planetary gearsets placed together into one component. Planetary gearboxes are also used in electric screwdrivers, sprinklers and applications that require large or multiple reductions from a compact mechanism. Planetary gearboxes are one of many variations of speed reducers and it is important that the right mechanism is used. Gearboxes may even be combined to produce the desired results and the most common kinds are helical gear reducers, worm gear reducers and inline gear reducers.

Planetary gearboxes gain their advantages through their design. The sun gear’s central position allows the planet gears to rotate in the same direction and for the ring gear (the edge of the planet carrier) to turn the same way as the sun gear. In some arrangements the sun gear can simultaneously turn all the planets as they also engage the ring gear. Any of the three components may be the input, the output or held stationary, which results in many different reduction ratio possibilities.

In many planetary gearboxes one component is held stationary with another component serving as the input and the other as output. The reduction ratios for planetary gearboxes are dependent upon the number of teeth in the gears and what components are engaged. Generally, the load ability and torque increases with the number of planets in the system because the load is distributed among the gears and there is low energy waste; planetary gearboxes are highly efficient, averaging between 96 and 98%. The design is complex, however, and difficult to access for repairs or maintenance.
