一般内圆磨床磨头中的滚珠轴承,因为经常在很高的转速下工作,所以损坏得特别快,常常一个轴承只有用几十个小时。我厂利用电器中的绝缘胶板,做成滚珠轴承保持器,代替了原有钢制的保持器,使轴承的使用寿命从几十个小时延长到三个月以上,这种保持器耐磨性好,工作中能保持轴承内清洁,并且可以保持运转中有足够的润滑油,避免轴承发热。制造方法:新的保持器是由两片环形绝 Ball bearings in the general internal grinding machine grinding head, because often at high speed work, so damaged very quickly, often only a few bearings with a few hours. I plant the use of electrical insulation sheet, made of ball bearing retainer, instead of the original steel retainer, the bearing life extending from dozens of hours to more than three months, this retainer wear Good sex, work can keep the bearing clean, and can keep running enough lubricant, to avoid bearing fever. Manufacturing method: The new holder is made of two rings absolutely
