AI Technical Summary

Technical Problem

The existing worm gear structure of golf bag carts has a rigid contact between the metal insert and the output shaft, resulting in high noise and poor stability. In addition, the housing has high production requirements and is prone to misalignment, which affects driving stability.

Method used

The design employs a worm gear structure with independent positioning of the output shaft. The worm gear is fixed by the first bearing, the output shaft is fixed by the second bearing, and a rubber coupling is used to achieve linkage, which reduces the bearing span and the length of the output shaft, reduces noise, and improves stability.

Benefits of technology

A low-cost, miniaturized golf bag cart drive system has been developed, reducing noise, improving driving stability, and simplifying assembly.
