Description

Technical Field

[0001] The utility model relates to the technical field of servo motors, in particular to an anti-deviation servo motor. Background Art

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device.

[0003] The servo motor can control the speed and position accuracy very accurately. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft.

[0004] The servo motor in the prior art usually consists of a motor body and an output shaft. After long-term use, the servo motor will inevitably have a transmission shaft that bends, causing one side to be too heavy or too light, which will cause the motor output shaft to be subjected to uneven force, thereby causing deviation. Bearing wear during normal use of the motor may also cause output shaft deviation. Harsh working environments, such as high temperature, humidity, dust, etc., may also cause deformation, corrosion or damage to motor components, thereby causing output shaft deviation.

[0005] In the prior art, the output shaft offset is usually dealt with by tightening the fixing screws, installing shock absorbers, and performing precise calibration before installation. However, such methods cannot prevent the output shaft offset of the servo motor due to normal wear after a period of use. Utility Model Content

The prior art usually deals with output shaft deviation by tightening fixing screws, installing shock absorbers, and performing precise calibration before installation. Such methods cannot avoid the problem of output shaft deviation caused by normal wear of the servo motor after a period of use.
