经常在恶劣条件下工作的推土机,其磨损相对比较大,尤其是行走机构。以往是将磨损的引导轮、支承轮、履带板等更新后,旧件弃之废墟。不仅加大修理费用,浪费大量材料,且由于配件紧缺,经常影响机械出厂。其实这些磨损件通过各种方法可以修复,并能保证质量。我们的修旧利废小组,仅一次就修复400多只支承轮等报废件,为国家节省了近三万多元。现以红旗100为例,将主要部件修复方法简述一下。一、引导轮的修理常见的故障一般是:引导轮顶部和滚道的磨损,轴承孔的磨损,轮缘轮辐裂纹等。 1.如果引导轮凸肩两侧面发生磨损,可用焊补修复如果凸肩下面滚道磨损,用钢 Bulldozers, which often work under harsh conditions, have relatively large wear, especially on walking gear. In the past, after the worn guide wheels, support wheels, and track shoes were renewed, the old parts were abandoned. Not only increase the cost of repairs, wasting a lot of material, and due to shortage of parts, often affecting the machinery factory. In fact, these wearing parts can be repaired by various methods and can guarantee the quality. Our team of repairing and renovating the old and the disabled only repaired more than 400 supporting wheels and other scrapped items, saving nearly 30,000 yuan for the country. Now take Hongqi 100 as an example to briefly describe the major component repair methods. First, the common failure of the repair of the guide wheel is generally: the wear of the top of the guide wheel and the raceway, the wear of the bearing hole, the rim spoke crack and so on. 1. If wear occurs on both sides of the shoulder of the guide wheel, weld repair can be used. If the raceway under the shoulder wears, use steel.
