滚动轴承轴箱部件的使用可靠性在很大程度上取决于车辆修理工厂轴箱部件的组装质量、装配工艺和规则的严格遵守以及测量的质量和精度。本文较详细地阐述一下向轮对轴颈上压装轴承内环时须保证规定的公盈量这个重要问题。在热装内环时,公盈量是主要的控制参数。众所周知,应把压装内环引起的轴颈挤压变形和压装表面上凸峰挤压值的测量公盈量与有效(实际)公盈量区别开来。在车辆段和修理工厂,通常要向运用轮对的轴颈上重 The reliability of the use of rolling bearing axlebox components depends to a large extent on the quality of the assembly of the axlebox components of the vehicle repair shop, the strict adherence to assembly processes and rules, and the quality and accuracy of the measurements. This article explains in more detail the important issue of ensuring the required public earning margin when compressing the inner ring of a bearing on a wheelset journal. In the hot inner ring, the amount of public earnings is the main control parameters. It is well-known that the measurement of the amount of peak crowded squeeze caused by press-fitting of an inner ring caused by press-fitting of the inner ring and the effective (actual) public earnings should be distinguished. In depots and repair shops, it is common practice to weight the journals that use wheelsets
