The service life of the precision gearbox is not only related to the quality of the reducer, but also on how to maintain the reducer in the ordinary time is also the key to the long time use of the planetary gearbox. Well, what problems we should pay attention to in the process of using the  3F precision gearbox? As a low backlash planetary gearbox manufacturer in China, here we would like to show you our professional views.

Firstly, before using the speed reducer, we should pay attention to check the gearbox construction, center distance specification, transmission ratio, input shaft connection mode, output shaft structure, input and output shaft direction and rotation direction are in conformity with the using requirement, and the worm input speed should not exceed 1500rpm. Secondly, the load should be applied gradually and cannot be started under full loaded. All speed reducers should be configured with exhaust plug. And oil level should be checked when using ( such as oil level mirror hole or open the oil plug ). Besides, the gear reducer should also try to avoid being exposed to the sun and the harsh environment. Ensure good ventilation environment near the motor fans, so as not to affect heat dissipation.

If the storage time of the servo gearbox is up to 4-6 months, you are required to check whether the oil seal is immersed in the lubrication oil. The lip of the oil seal may be stick on the shaft and even lose the elasticity. Because the proper elasticity is the working condition of the oil seal, it is recommended to replace the oil seal, and all the rubber and breathable hole can not be covered with paint.

The standard working environment of the speed reducer is at -5 C -40 C.

During the model selection process of reducer gearbox, normally several parameters will be considered including the reduction ratio of the planetary gearbox, the output speed of the gearbox, the matching motor power and the output mode of the speed reducer. All of these parameters are very important. Besides, there are still other related parameters. Today 3F mainly talks about the calculation of the reducer torque.

Motor torque, that is, the output torque of the motor, is one of the basic parameters of the motor. The unit is N.M.

Formula: T=9550P/n

This formula is a calculation formula for the relationship between torque, power and speed commonly used in engineering.

Meanings of each letter in the formula:

  • T-torque;
  • 9550-constant (do not have to find outits source);
  • P-motor power (KW);

n–output speed (rev/min r/min)

Note: if When calculating the torque through the reducer gearbox, the factor of gear transmission efficiency loss should be considered.

Servo motor torque calculation formula: T = F * R * reduction ratio. For example: If you need the machine to drive a 100kg object, knowing the move distance R = 50mm, and the reduction ratio is 1:50, please calculate the torque of the servo motor?

Answer: 100×9.8 (gravity acceleration) x0.05×0.02=0.98N.M

Reducer torque calculation formula

  1. Speedratio: speed ratio = motor output revolutions ÷ reducer output revolutions (“speed ratio” is also called “gear ratio”)
  2. Knowingthe motor power, speed ratio and theuse coefficient and you want to know the torque of the reducer.  The formula is as follows:

reducer torque = 9550×motor power÷motor power input revolution×speed ratio×use coefficient

  1. Knowingthe torque, the output revolution of the reducer and the use coefficient, then how to calculate the motor power of the reducer?

The following formula: Motor power = torque÷9550×motor power input speed÷speed ratio ÷use coefficient.
