Reduction ratio: the ratio of input speed to 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.The reducer malfunctions when the output torque exceeds twice.
Noise: The unit is decibel dB (A). This value is actually measured when the input speed is 3000 rpm, without load, and at a distance of 1 meter from the reducer.
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, and this angular displacement is the return clearance.The unit is "minute", which is 1/60 of a degree.
