日本八王子车辆段修理的货车,主要运行在坡道和小半径曲线上。这些车辆的主要问题是轮缘异常磨耗。过去不摘车或不分解加修轮缘,一般都是用手推动车辆,随着车轮转动,再用特殊的车刀切削,整个作业危险性很大。为改变这种作业方式,该段研究试制了空气驱动式轮缘切削机,架起车轮,用空气马达带动车轮回转。这种切削机,在货车处于静止状态下即可作业,不仅提高了效率也保证了安全。可 Japan’s Hachioji depot repair truck, mainly running on the ramp and small radius curve. The main problem with these vehicles is the unusual wear on the rim. The past did not pick up the car or do not decompose and repair rim, are generally driven by hand vehicles, with the wheel rotation, and then cut with a special turning tool, the entire operation is very dangerous. In order to change this mode of operation, this section of the trial trial of the air-driven rim cutting machine, set up the wheels, with air motor driven wheel rotation. This cutting machine, the truck is in a quiescent state to work, not only improve the efficiency but also ensure the safety. can
