砂轮主轴和轴承是磨床的关键零件。主轴与轴承的调整好坏,直接影响磨削精度及使用寿命。根据我厂多年来生产M1080型和M1083型无心磨床的经验,本文着重就M1080型长五片调位多油楔径向轴承的调整和修理作一介绍。 1.结构磨头由壳体1、主轴2、轴瓦8和7、杠杆机构13等零件所组成(图1和2)。四片下轴瓦7 Wheel spindle and bearing are the key components of the grinding machine. Spindle and bearing adjustment is good or bad, directly affect the grinding accuracy and service life. According to my experience in producing M1080 and M1083 centerless grinding machines over the years, this article focuses on the adjustment and repair of the M1080 long five-piece multi-wedge radial bearing. 1. Structural grinding head from the shell 1, the spindle 2, bearing 8 and 7, the lever mechanism 13 and other components (Figure 1 and 2). Four under the bearing 7
