本文主要探讨我公司早期的路面铣刨机使用中支重轮损坏的原因、解决方法以及支重轮的正确使用方法。施工中反映出的主要问题是:支重轮两轴端面有润滑油渗出,并伴有局部发热、发烫;多数支重轮因烧死而导致报废,严重影响铣刨机工作。通过观察和分析,履带行走机构中的台车架制造不合格以及铣刨机使用不正确是导致支重轮过早损坏的主要原因。
This article mainly discusses the reasons for the damage of the support rollers in our company’s early pavement milling machine, the solutions and the proper use of the rollers. The main problems reflected in the construction are: Lubricant oozing on the two shaft ends of the roller bearing accompanied by local heating and scalding; Most roller wheels are scrapped due to burning, seriously affecting the work of the milling machine. Through the observation and analysis, the failure of the trolley frame in the crawler track mechanism and the improper use of the milling machine are the main reasons for the premature failure of the drum.
