Reduction ratio: The input speed of the precision planetary reducer is higher than the output speed.

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

　　Full load efficiency: refers to the transmission efficiency of the reducer under the maximum load condition (the output torque is stopped due to failure).

　　Lubrication method: The precision planetary reducer does not need lubrication.The reducer is fully sealed, so there is no need to add grease during the entire service life.

　　Noise: The unit is decibels.This value is measured when the input speed is 3000 rpm, without load, and one meter away from the reducer.

　　Rated torque: a standard for reducers.Under this value, when the output speed is 100 rpm, the life of the reducer is the average life.Over this value, the average life of the reducer will be reduced.When the output torque exceeds twice this value, the reducer malfunctions.

　　Number of stages: the number of sets of planetary gears.Since one set of planetary gears cannot meet the larger transmission ratio, sometimes two or three sets of planetary gears are needed to meet the requirements of users for larger transmission ratios.Due to the increase in the number of planetary gears, the length of the two- or three-machine reduction stage will increase, and the efficiency will decrease.

　　Return clearance of precision planetary reducer: fix the output end, and rotate the input end clockwise and counterclockwise to make the output end produce rated torque +-2% torque, there is a slight angular displacement at the input end of the reducer, this angular displacement That is the return gap.The unit is "arc minutes", which is one sixtieth of a degree.The usual return clearance value refers to the output end of the reducer.
