φ2.2m圆锥破碎机具有破碎率高、产量高、能耗少、产品 粒度均匀和适于破碎硬矿石等优点,而获得广泛应用,其中以标准型和短头型应用最广。 φ2.2m圆锥破碎机动锥衬板装配时需要将圆锥头打紧,使其与主轴螺丝有一定的预紧力,再浇锌填充衬板与锥体的空间,以减少对锥体的磨损,同时对衬板起到缓冲作用。但是,因为动锥头与主轴螺纹的预紧力没有检测工具,经常造成止动齿轮与圆锥头的螺纹啮合后,预紧力达下到技术要求。大家知道,圆锥破碎机动锥空车时顺时针旋转（从上往下看）,负载时逆时针旋转,时间一长,由于主轴螺纹所受力矩处于往复状态,动锥头与分矿盘相对主轴左右摆动,使止动齿轮与圆锥头啮合松动,时间一久止动齿轮凸台与主轴上的凹槽配合处磨损
φ2.2m cone crusher has the advantages of high crushing rate, high output, low energy consumption, uniform product size and suitable for crushing hard ore, etc., and has been widely used, of which the standard and short-type the most widely used. φ2.2m cone crusher moving cone lining assembly need to cone head tightening, so that it has a certain preload with the spindle screw, and then fill zinc filling liner and cone space to reduce the wear on the cone, at the same time Play a cushion on the liner. However, because there is no testing tool for the pre-tightening force between the driving cone head and the main shaft thread, the pre-tightening force reaches the technical requirement after the engagement between the stopping gear and the cone head thread is often caused. As we all know, cone crusher moving cone empty clockwise rotation (viewed from above), load counterclockwise rotation, a long time, due to the spindle screw torque in the reciprocating state, the dynamic cone head and sub-ore relative to the spindle Swing left and right so that the stop gear and the cone head loose engagement, a long time to move the gear boss and the spindle with the groove wear Department
