AI Technical Summary
During use, the inner diameter of the motor gasket increases due to the rotation of the shaft, which reduces its sealing performance and poses a risk of leakage.
It adopts a combination structure of gasket, protruding ring, tightening component, flange plate and fixing component. Through the design of elastic rope and wrapping sleeve, the gasket is tightened and limited to ensure sealing effect.
It effectively maintains the seal between the gasket and the shaft, prevents leakage, and improves the sealing and stability of the internal environment of the motor.
