我厂四台医用小型砂轮机有三挡调速装置,最高转速为10000转/分,采用滑动摩擦方式及用一般工业脂润滑。使用结果,往往1～2个星期需拆检,更换零件。1982年,除对结构改进(以滚动代替滑动)外,还改用7014-1高低温合成脂(一坪化工厂生产)。试用近一年来,温升正常,运行良好。 Our factory has four sets of medical small grinder with three speed governor, the maximum speed of 10,000 rev / min, the use of sliding friction and the use of general industrial grease lubrication. Use the results, often 1 to 2 weeks to be dismantled, replacement parts. In 1982, in addition to the structural improvement (in order to roll instead of sliding), but also to 7014-1 high and low temperature synthetic resin (Ippouni Chemical Factory production). Trial nearly a year, temperature rise normal, well-run.
