AI Technical Summary
Technical Problem
Existing motor shafts are prone to wear during rotation under pressure, which can lead to shaft breakage and water leakage in severe cases.
Method used
A shaft protection pre-installation mechanism is set at both ends of the motor shaft, including first and second pressure rings and built-in compression pads. The rotation of the screw and the column head drives the clamp and the push plate to apply constant extrusion force to expand the built-in compression pads and provide wear protection.
Benefits of technology
It effectively prevents wear on the motor shaft in pressure-bearing parts, extends service life, avoids shaft breakage and water leakage, and improves the reliability of the device.
