Technical Field
[0001] The utility model relates to the field of motor equipment, in particular to a shaft retaining ring pressing device. Background Art
[0002] The installation of motor shaft retaining rings (also often called shaft retaining rings or shaft elastic retaining rings) is an important and common process. Shaft retaining rings are mainly used to fix components on the motor shaft to ensure that they do not move axially during operation, thereby ensuring the stability and reliability of the motor. However, most companies currently still use manual methods to press shaft retaining rings into the motor shaft grooves. This method not only requires operators to endure high-intensity physical labor, but also long-term work can easily lead to fatigue, affecting work efficiency and personnel health. More importantly, due to the unevenness of human force, shaft retaining rings are very easy to deform during the pressing process, which not only reduces its fixing effect, but also increases the risk of failure during motor operation, posing a threat to the overall performance and safety of the motor.
