液压柱塞泵在厂内装配、进行台架试验 ,而在厂外与主机连接时 ,经常发生花键副配合不当 ,甚至无法装配等问题。究其原因 ,多为工件热处理后花键畸变难以加工或者不能加工。根据渗氮工件呈实体涨大 (轴涨大、孔缩小 )的特点 ,对Ａ2Ｆ5 5斜轴式柱塞液压马达传动轴渗氮花键齿厚涨
Hydraulic piston pump assembled in the factory for bench test, and when connected with the host outside the plant, often with improper spline fitting, or even assembly problems. The reason, mostly after the workpiece heat treatment spline distortion difficult to process or can not be processed. According to the characteristics of nitriding body showed physical ups and downs (shaft up, hole shrinkage), A2F5 5 bevel gear motor shaft nitriding spline tooth thick
