What factors affect the efficiency of the servo planetary gearbox?
Each servo planetary gearbox has a rated input speed and number of planetary gears. Since only one set of planetary gears cannot meet the large transmission ratio, two or three sets of such gears are sometimes required to meet the requirements of users. In other words, the larger the reduction ratio, the more stages are required and the lower the efficiency.

So, how to check the rebound TQG servo planetary reducer?

Fix the output terminal and rotate the input terminal clockwise and counterclockwise, which will produce a rated torque of approximately +-2% torque, and the input terminal will have a slight angular displacement called a gap. The unit is "minute", which is one sixtieth of the degree. It is also called the return gap. The specified input speed of the servo planetary gearbox can reach up to 18,000 revolutions (depending on the size of the gearbox itself. The larger the reducer, the smaller the rated input speed).

The output torque of industrial servo planetary gearboxes usually does not exceed 2000Nm, and customized super-torque gearboxes can reach output torques of more than 10000Nm. The operating temperature range is usually -25°C to 100°C. The working temperature can be changed by changing the grease.

Therefore, the efficiency of the servo planetary gearbox is related to the number of stages of the reducer.
