Screw lift, screw jacks, worm lifter lifts JWM spiral screw, ball screw lift SWL, QWL worm screw lift, JRSS screw lifts shift compensation when the worm lead angle is less than the equivalent frictional engagement between the teeth When the angle jwm screw lift, with a self-locking mechanism can be achieved swlqwl reverse self-locking screw lift, which can only be driven by the worm, the worm can not be driven by the worm. Self-locking worm screw lift mechanism as used in its heavy machinery, the reverse self-locking can play a security role. Error compensation is to assemble the parts themselves errors through the appropriate screw lift, a certain degree of mutual offset phenomenon, a method of adjusting the device to ensure the accuracy of the trajectory. Machinery and equipment maintenance, there is a shift compensation and comprehensive compensation two common error compensation method. 1. Axial movement error compensation method of compensation: should first measure the vertical direction of the error and its position on the spindle bearings positioned face and spindle centerline: the re-measurement of the end face runout error and its highest point in the last position of the thrust bearing so that the highest point of the end surface of the bearing position shifted to the lowest point of the thrust bearing assembly and the end face runout together, we can reduce the amount of axial movement of the error. Screw lift for clearance adjustment method.
