一、车架故障及修理车架的故障主要是扭曲、弯曲和对角变形以及铆钉松动。由于车架是拖拉机的基础部件,技术状态的好坏,会直接影响机车总体的正常工作,因此,进行底盘修理之前,首先应对车架进行检查。 1.铆钉是否松动,铆钉头是否有裂纹或贴合不良。如有少量铆钉发生上述缺陷,可更换铆钉,不然须重新铆合车架。 2.用对角拉线的方法检查对角变形程度。方法是前后以引导轮轴小轴套和后轴卡瓦销的销钉孔为基点对角拉线。两条线的长度差设计要求为2毫米,但我们认为这样大的物件,其基点不十分规矩,很难保证,可否不超过3毫米。扭曲要求两条线的交点距离不
First, the frame failure and repair Frame failure is mainly twisted, bending and diagonal deformation and rivets loose. Since the frame is the basic component of the tractor, the status of the technology will directly affect the overall work of the locomotive. Therefore, before the chassis repair, the frame should be inspected first. 1. Whether the rivets are loose, the rivet head is cracked or the fitting is poor. If a small amount of rivets in the above defects, rivets can be replaced, otherwise must riveting the frame. 2. Use diagonal wire method to check the degree of diagonal deformation. Before and after the method is to guide the axle shaft sleeve and the rear axle pin hole pin hole as the base diagonal cable. The length difference between the two lines is designed to be 2mm, but we think that such a big object, the base point is not very rules, it is difficult to guarantee, can not exceed 3mm. Distortion requires that the distance between the two lines is not
