磨7120(一型)平面磨床砂轮轴的轴承润滑,原设计采用油杯加油,由于油杯式加油压力不足,易造成轴承缺少润滑,致使轴承和轴颈表面研坏,被迫停机检修。北京量具刀具厂将其改为强制性自动润滑。利用磨头上原注油杯改为进油管路,并在对面比进油管孔高20毫米、距主轴套筒端面75毫米处,增加一回油管路(如图1),使之能循环润滑。 Grinding 7120 (a type) surface grinder bearing lubrication of the wheel shaft, the original design using oil cup refueling, due to lack of oil cup refueling pressure, easy to cause the bearing lack of lubrication, resulting in bearing and journal surface grind, was forced to shut down for maintenance. Beijing Measuring Tool Factory will be changed to mandatory automatic lubrication. The use of grinding the original injection cup into the oil into the pipeline, and in the opposite than the inlet hole 20 mm high, 75 mm away from the spindle sleeve end, an increase of oil pipeline (Figure 1), so that it can cycle lubrication.
