砂轮主轴箱两个润滑点油路1、7(图1)按传统方法可用管接头2和油管5等相联。这种方法的缺点是: 1.由于管接头2和油管5等装在主轴上部,所以影响螺母3、4等零件的装卸和调整; 2.油管振动时对高精度主轴振动有一定影响, 3.管接头6处箱体上的螺纹加工工艺性不好。 可用钻孔法或铸孔?
Wheel spindle box Two lubrication point oil line 1,7 (Figure 1) According to the traditional method available pipe fittings 2 and tubing 5 and other associated. The disadvantages of this method are as follows: 1. Since the pipe joint 2 and the oil pipe 5 are mounted on the upper part of the spindle, the loading, unloading and adjustment of the nuts 3, 4 and other parts are affected. 2. The vibration of the tubing affects the high-precision spindle vibration to some extent. 3 Pipe connector 6 box on the thread processing technology is not good. Available drilling method or cast hole?
