AI Technical Summary

Technical Problem

Existing planetary gear reducers are prone to belt slippage from pulleys due to vibration in washing machines, affecting the stability and reliability of power transmission.

Method used

A planetary washing machine reducer with an anti-detachment structure was designed. By covering the pulley with an anti-detachment cover and installing guide rollers inside the anti-detachment cover, the anti-detachment cover is fixed by the cooperation of the slider and the limiting groove, preventing the belt from detaching from the pulley. The overall reliability and strength are improved by multiple sets of reduction gears.

Benefits of technology

This effectively prevents the belt from separating from the pulley, improves the stability and reliability of the washing machine, extends the belt's lifespan, and ensures the continuity of power transmission.
