轴瓦(滑动轴承)是钢筋切断机的重要零件之一,也是易损件。其工作状况的正常与否,直接关系到钢筋切断机的工作性能和使用状况,分析轴瓦失效的目的在于了解轴瓦损坏的原因与机理,从而确定防止或减缓轴瓦失效的改进措施。本文根据钢筋切断机在多年使用中出现的问题,对轴瓦的失效形式、机理进行分析,并提出改进措施。
The bearing (sliding bearing) is one of the important parts of the steel bar cutting machine and it is also the wearing part. Whether the working condition is normal or not is directly related to the work performance and the use status of the steel bar cutting machine. The purpose of analyzing the failure of the bearing pad is to understand the cause and mechanism of the damage of the bearing pad, so as to determine the improvement measures for preventing or slowing down the failure of the bearing pad. This paper analyzes the failure modes and mechanisms of bearing bushes based on the problems that occur in the use of rebar cutting machines for many years, and proposes improvement measures.
