前言目前我国内燃机车柴油机轴瓦是在铜背上用离心浇注法浇挂一层白合金.白合金牌号为??2.白合金层精加工后的厚度为0.75毫米.在使用过程中白合金层的容许磨损为0.25毫米左右,这一磨耗值系根据不同类型的轴瓦与轴之间的最大容许间隙来确定的.
Foreword At present, China’s diesel locomotive diesel engine bearings are cast on the back of the copper centrifugal casting method of pouring a layer of white gold. White alloy grade is ?? 2. White alloy layer after finishing the thickness of 0.75 mm. In the course of the white alloy layer The allowable wear is about 0.25 mm. The wear value is determined according to the maximum allowable clearance between different types of bearing bushings and shaft.
