Abstract：

The upper end of main screw spindle for clutch type screw press is connected with the friction disc of clutch through the involute spline, where the torque transmitted is larger, and with the increasing of use time, under the action of wear and impact, the spline fit clearance increases, which affects the normal use of equipment. Therefore, in order to solve this problem, the maintenance example of main screw spindle spline for J55-4000 clutch type screw press was analyzed, and an economical maintenance method was adopted. Then, by increasing the expansion sleeve, the influence of spline fit clearance on the equipment wear was eliminated, and the impact and friction wear caused by the back and forth movement of the friction disc for clutch were avoided. According to the service condition after maintenance, the above method is safe, reliable, economical and practical, which extends the service life of the main screw spindle for screw press.
