AI Technical Summary

Technical Problem

Existing elevator traction sheaves cannot effectively absorb vibration and impact forces when starting under full load or during emergency braking, leading to damage to the traction machine and dynamic imbalance, which affects safety.

Method used

A shock-absorbing device for high-power elevator traction sheaves was designed. By combining support beams, buffer components, guide components and springs, the elastic deformation of the springs is used to absorb the impact force, and the guide sheaves and rollers support the guide steel wire rope to ensure its stable operation.

Benefits of technology

It effectively absorbs the vibration and impact of the elevator traction sheave, reduces the wear of the wire rope, ensures the stable operation of the elevator traction sheave, and improves safety and service life.
