Advantages and disadvantages of planetary reducer.


Planetary reducer is a versatile industrial product that can reduce the speed of the motor while increasing the output torque. Planetary reducers can be used as supporting components in lifting, excavation, transportation, construction and other industries. Let's talk about ShuoLi Hydraulic.

Since one set of planetary gears cannot meet the larger transmission ratio, sometimes 2 or 3 sets are needed to meet the requirements of the user's larger transmission ratio. Due to the increase in the number of planetary gears, the length of the 2-stage or 3-stage reducer will be reduced. increase, the efficiency will decrease. Return clearance: When the output end is fixed, the input end is rotated clockwise and counterclockwise, so that when the input end generates rated torque +-2% torque, there is a slight angular displacement at the input end of the reducer, and this angular displacement is the return clearance. Unit It is "cent", which is one-sixtieth of a degree. It is also called backlash.

With the continuous development of the reducer industry, more and more enterprises have used the reducer. The planetary reducer is an industrial product, and the planetary reducer is a transmission mechanism. Its structure is tightly combined with the gear box by an inner gear ring. On the casing, there is a sun gear driven by external power in the center of the ring teeth, and in between there is a set of planetary gears composed of three gears equally divided on the tray, the planetary gears rely on the output shaft, The inner gear ring and the sun gear support float during the period; when the input side power drives the sun gear, it can drive the planetary gear to rotate, and follow the track of the inner gear ring to revolve along the center, and the rotation of the planet drives the output shaft connected to the tray to output power.

A mechanism that uses a gear speed converter to reduce the number of revolutions of the motor (motor) to the desired number of revolutions and obtain a large torque. In the reducer mechanism used to transmit power and motion, the planetary reducer is a precision reducer, and the reduction ratio can be accurate to 0.1 rpm - 0.5 rpm.

The internal gear of the planetary reducer adopts 20CrMnTi carburizing quenching and grinding, which has the characteristics of small size, light weight, high bearing capacity, long service life, stable operation, low noise, large output torque, large speed ratio, high efficiency and safe performance.

It has the characteristics of power splitting and multi-tooth meshing. It is a new type of reducer with wide versatility. Input power can reach 104kW. It is suitable for lifting and transportation, construction machinery, metallurgy, mining, petrochemical industry, construction machinery, light industrial textiles, medical equipment, instrumentation, automobiles, ships, weapons and aerospace and other industries. New varieties of planetary series WGN fixed shaft drive reducers , WN mother-in-law gear drive reducer, elastic load-sharing less tooth difference reducer.
