货车转向架的可靠性和动力性能在很大程度上取决于轴箱和侧架连接部件的结构。实践表明,转向架侧架和轮对现在的连接方法,在车辆运用强度很大的条件下,不能完全满足对于车辆走行性能提出的要求,因而转向架侧架、轮对和轴箱在运用中会发生故障。为了消除故障,必须摘车修理。众所周知, -X3-O型转向架的侧架两端自由支承在轴箱上,侧架轴箱导框和轴箱体导槽之间在纵向和横向都有间隙。按照货车段修规程,滑动轴承轴箱部件中的总间隙在转向架纵向应为6～12mm,横向
The reliability and power performance of truck bogies depend largely on the structure of the axlebox and sideframe connecting components. Practice shows that the bogie side frame and the wheel of the current connection method, the vehicle under the conditions of strength, can not fully meet the requirements for the performance of the vehicle running, and thus bogie side frame, wheel set and axle box in use A failure will occur. In order to eliminate the fault, it is necessary to pick up the car for repair. It is well-known that both ends of the side frame of the -X3-O bogie are freely supported on the axle box. There is a gap between the side frame axle guide frame and the axle box guide groove in the longitudinal and transverse directions. In accordance with the truck section repair procedures, the total clearance of the bearing components in the sliding bearing should be 6 ~ 12mm in the longitudinal direction of the bogie,
