Performance Analysis of Broom Drive Motor Speed Reducer on Electric Sweeper Cars
Abstract:
In current electric road sweeper car units, the broom rotation speed is often excessively high, leading to inefficient sweeping performance and accelerated wear of the broom bristles. To address this issue, a speed reducer can be installed to lower the broom's rotational speed, thereby extending its service life and achieving an optimal sweeping effect. This study aims to determine the optimal broom rotation speed for effective sweeping and minimal wire wear. An experimental test was conducted using a prototype electric road sweeper, evaluating various broom rotational speeds and their effects on sweeping efficiency and wear rate. The results showed that the optimal broom speed for sweeping leaf litter is 109 RPM, achieving a waste collection success rate of 87.5% at a sweeping speed of 1 km/h. Furthermore, the measured wear rate of the broom wire per revolution was 0.000022 mm.
