How about the performance of planetary reducer?

In the reducer family, planetary reducer is widely used in servo, stepping, DC and other transmission systems because of its small size, high transmission efficiency, wide deceleration range and high accuracy. On the premise of ensuring precision transmission, it is mainly used to reduce speed, increase torque and reduce the load/motor moment of inertia ratio.


Several key technical parameters to measure the performance of planetary reducer are: reduction ratio, average life, rated output torque, return clearance, full load efficiency, noise, lateral/radial force and working temperature.


Reduction ratio: the ratio of output speed to input speed.


Stage: The sun gear and its surrounding planetary gears form an independent reduction gear train. If there is only one gear train in the reducer, we call it "Stage 1". In order to obtain a large reduction ratio, multi-level transmission is required. The reducer is divided into three stages, and the reduction ratio is from 3 to 512.


Average life: refers to the continuous working time of the reducer at the highest input speed under rated load.


Rated output torque: refers to the allowable output torque for long-term operation under rated load. The maximum output torque is twice the value.


Return clearance: when the output end is fixed and the input end rotates clockwise and counterclockwise to make the output end produce ± 2% torque of the rated torque, there is a small angular displacement at the input end of the reducer, which is the return clearance. The unit is "minutes of arc".


Lubrication method: the planetary reducer does not need lubrication during the whole use period.


Full load ratio: refers to the transmission efficiency of the reducer under the maximum load. It is a key index to measure the reducer. The reducer with high full load efficiency has less heat and good overall performance.


Noise: unit: decibel (dB) A. This value is measured when the input speed is 3000 rpm, without load, and one meter away from the reducer.

Working temperature: refers to the allowable temperature of the reducer under continuous and periodic working conditions. At present, the reducer of military series can work under the environment of - 50~+100 degrees.
