What Is A Servo Gearbox?
Servo gearbox is another name for “planetary reducer” in the industry. It is generally used for low-speed and high-torque transmission equipment. The principle is to pass electric motor, internal combustion engine, motor or other high-speed running power through the input shaft of the reducer. The gear with a small number of teeth on the gear meshes with the large gear on the output shaft, so as to achieve the purpose of deceleration.
Important parameters
Reduction ratio: the ratio of the input speed to the output speed.
Number of stages: the number of sets of planetary gears. Generally, the maximum can reach three levels, and the efficiency will be reduced.
Full load efficiency: The transmission efficiency of the reducer under the maximum load condition (the output torque is stopped due to failure).
Working life: The accumulative working time of the reducer under rated load and rated input speed.
Rated torque: the torque for long-term operation allowed by the rated life. When the output speed is 100 rpm,the life of the reducer is the average life. When this value is exceeded, the average life of the reducer will be reduced. When the output torque exceeds twice, the Chengsu engine malfunctions.
Noise: The unit is decibel dB (A). This value is actually measured when the input speed is 3000 rpm and the distance between the reducer and the reducer is 1 meter without load.
Backlash: The input end is fixed, and the output end rotates clockwise and counterclockwise. When the output end bears plus or minus 2% of the rated torque, the output end of the reducer will have a slight angular displacement. This angular displacement is the return clearance. Also called “”backlash””. The unit is “”minute””, which is 1/60 of a degree.
