Teach you how to correctly select a servo planetary reducer?

1) First, you should choose a planetary gear reducer that matches the motor mounting flange. Motors are classified according to the mounting flange. For example: servo motors are divided into 40 series, 60 series, 80 series, 110 series, 130 series, 150 series, 180 series, etc.; stepper motors are divided into 42 series, 57 series, 86 series, 110 series, 130 series, etc. The planetary reducer is also modeled according to the mounting flange, so the 400W60 series servo motor or 57 series Stepper motors are generally equipped with 60 series planetary gear reducers; 750W80 series servo motors or 86 stepper motors are generally equipped with 80 series planetary reducers. 2) Determine the reduction ratio: The specific reduction ratio is determined by the equipment manufacturer according to its own equipment requirements. 


At present, planetary gear reducers are generally divided into three levels, and some manufacturers only have two levels. The first-level reduction is generally below 20; the second-level reduction is between 20 and 100, and the third-level reduction is above 100. The higher the level, the higher the price. The more expensive, the bigger the gap. 3) Determine the input and output forms of the reducer: on the input side, there are hole input and shaft input; on the output side, there are shaft output, hole output, flange output, etc. 4) The shape of the reducer: there are round reducers, There are also square reducers. 


Because the square rated output torque is larger than the round one, and the manufacturing process is more complicated than the round one, the square reducer is more expensive than the round one. Note: If you still don’t know how to choose, just tell the sales engineer what type to use. Motor model, required reduction ratio, input and output form, is it round or square? Are there any requirements for the output end of the reducer? If there are no special requirements, it is usually done according to the manufacturer's standards.
