3M4325圆锥滚子球形基面磨床是轴承行业的专用机床。该机床送料机构的两根对滚轴利用液压马达驱动。一只新的液压马达使用不到半年,就因零件磨损造成液压油内泄外漏,使原先出力不大的液压马达难以驱动,故障多,维修费用大。为此,我们对送料机构的驱动动力进行了如下的改进。 1.结构特点 将液压马达及相应的油管拆除(其余零部件均不改变),安装蜗杆蜗轮减速器及一台小电动机(见图

3M4325 Tapered Roller spherical surface grinder is a bearing machine tool industry. The two pairs of rollers of the machine feed mechanism are driven by a hydraulic motor. The use of a new hydraulic motor less than six months, due to wear and tear caused by wear and tear parts leaks outside the hydraulic oil, so that the original hydraulic motor output is difficult to drive, fault and maintenance costs. To this end, we have made the following improvements to the driving force of the feeding mechanism. 1. Structural Features Remove the hydraulic motor and the corresponding tubing (the remaining parts are not changed), install the worm gear reducer and a small motor (see figure
