Planetary Gearbox

Manufacturer of Planetary Gearbox, Planetary gear reducer, Planetary geared motor, Epicyclic gearing, Planetary gearing, Gearboxes, can interchange and replace with brevini gearbox, david brown gearbox and so on.

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.

Metallurgical Mining Machinery

In the metallurgical industry, a stably and reliably running gearbox can determine whether the entire production line can work properly. Failure of the gear set can lead to serious consequences. Usually, the gearhead works even in heavy-duty, high shock load, high or low speed, high temperature, high pollution, and other harsh operating environments.

Equipped with high-performance bearings, our gear reducers can meet the demanding needs of the metallurgical industry. The gearbox can be used on crushing machines, grinding machines, dryers, sand making machines, vibrating feeders, grab steel machines, crawler loaders, and other metallurgical and mining machines.
