1抱轴瓦的特点1.1结构在我国铁路运行的抱轴瓦结构的机车,基本采用对开式斜动压滑动轴承,用于承受倾斜方向上的载荷。其轴承座与轴承盖剖分,安装方便,且轴瓦磨损后可通过抽减剖分面处的垫片来调整轴与轴瓦间的径向间隙。轴瓦衬材料选用锡基轴承合金,许用比压25MPa,有较好的退让
1 axle bearing features 1.1 Structure In our country railway running axle bearing structure of the locomotive, the basic use of open oblique pressure sliding bearings, used to withstand the load in the direction of tilt. Its bearing seat and bearing cap are cut apart, and the installation is convenient. After the bearing pad is worn, the radial clearance between the shaft and the bearing bush can be adjusted by pumping the gasket at the split surface. Bush lining material selection tin-based bearing alloy, the allowable pressure 25MPa, a better concession
