由于斯太尔自卸车后桥平衡轴承重大,受冲击力强,导致其与滑动轴承间磨损时有发生。以往采用补焊后手工磨削方法,对磨损后的平衡轴进行修复。由于手工磨削完全凭经验进行,且修理人员各自的技术水平不同,使得修复质量参差不齐。主要表现在:平衡轴轴面圆柱度难以控制,其与轴承装配后可能存在径向跳动;平衡轴磨削表面不 As the Steyr dump truck rear axle balance bearing a great impact by the strong, resulting in the wear and tear with the sliding bearing occurs from time to time. In the past, manual grinding method after repair welding was adopted to repair the worn balance shaft. As the manual grinding completely based on experience, and repair technicians each different level, making the quality of the uneven repair. Mainly in: balance shaft axial cylindrical surface difficult to control, with the bearing assembly may exist after the radial runout; balance shaft grinding surface is not
