分油器是装在摩擦焊机主轴上的一个重要部件，它的作用是使高速旋转的主轴得到润滑，并通过它的供油与回油使旋转夹具夹紧与松开焊件。由于分油器与主轴的配合间隙较小，仅为0．015～0．025mm，使用中常出现主轴与分油器研卡抱死现象，维修困难，又影响生产。为了解决这个问题 Oil separator is installed on the friction welding machine spindle is an important component, its role is to make high-speed rotation of the spindle lubrication, and through its oil supply and return to the rotating clamp clamping and release the weldment. Due to the small gap between the oil separator and the spindle, only 0.015 ~ 0.025mm, the use of the spindle and the oil separator often appear jamming, maintenance difficulties, but also affect the production. To solve this problem
