Description

Technical Field

[0002] In the mechanical transmission system, the commutator is an important component that can change the rotation direction or speed of the output shaft. However, during the use of the traditional commutator, the internal bushing is easily deformed due to factors such as centrifugal force generated by high-speed rotation and thermal expansion caused by temperature changes. Since there is no buffer structure inside, the anti-inner hole bushing cannot be buffered, resulting in rupture, which affects the normal operation of the commutator and reduces the transmission efficiency. In addition, the existing commutator is not equipped with a sensor, and the working status of the commutator cannot be monitored in real time, and abnormal temperature rise or vibration exceeding the standard cannot be detected.
