车床主轴的前轴承用两个螺帽1及3固定在主轴箱体内,并籍这两个螺帽来调整主轴4的颈与轴承2的壁之间的径向间隙(图)。根据磨损的程度向古拉轴承2,於是轴承末端的螺纹逐渐由螺帽1中退出来。螺帽1夹持轴承的强度减小,所以被磨损的锡青铜轴承就得换新的。 为了延长轴承工作寿命技师 The front bearing of the lathe spindle is fixed in the spindle housing by means of two nuts 1 and 3 and the two nuts are used to adjust the radial clearance between the neck of the spindle 4 and the wall of the bearing 2 (figure). According to the degree of wear to the Gouraki bearing 2, then the thread at the end of the bearing is gradually withdrawn from the nut 1. The strength of the nut 1 clamping bearing is reduced, so the worn tin bronze bearings have to be replaced. In order to extend the service life of bearing technician
