车辆滚动轴承使用的“车轴滚动轴承润滑脂”随着车辆速度的提高和维修频率的增大,对其使用条件要求更加严格了。从车轴轴承的润滑方面,也不断要求提高润滑脂本身的性能。 1.车轴轴承润滑方面的问题 车轴用园柱滚动轴承适于高速度,具有体积小、重量轻和维修简便等优点,比其他园锥滚动轴承等优越,所以现在大量应用。 但是应用园柱滚动轴承的轴箱,一般因承受摆动载荷而采用球面园柱,在构造上允
Rolling-wheel bearings used in the “axle rolling bearing grease” As the vehicle speed and maintenance frequency increases, the requirements of its use of more stringent requirements. From the axle bearing lubrication, but also continue to require the performance of the grease itself. 1. Axle bearing lubrication problems Axle with cylindrical roller bearings for high speed, with small size, light weight and easy maintenance, etc., than other tapered roller bearings and other advantages, so now a large number of applications. However, the application of cylindrical roller bearing axle box, usually due to bear the swing load and the use of spherical cylinder, in the construction of Yun
