A worm gear transmission axis coincidence detection and adjustment method
By applying a push-pull force inside the machine tool to measure the gap between the worm gear and worm wheel mating surfaces and calculating the theoretical gap ΔS, the problem of high difficulty in aligning and adjusting the worm gear transmission axis is solved, achieving fast and accurate axis alignment and improving transmission reliability and accuracy.

Abstract
The application discloses a worm gear transmission axis coincidence detection and adjustment method, comprising the following steps: pre-installing a worm gear and a worm in a lathe bed body, movably connecting one end of the worm gear to a mounting base through a connecting shaft; applying a pushing force to the mounting base to make the worm gear translate to a first target position; measuring and obtaining the minimum gap Delta L between the mounting base and the lathe bed body; applying a pulling force to the mounting base to make the worm gear translate to a second target position; measuring and obtaining the maximum gap Delta E between the mounting base and the lathe bed body; according to the minimum gap Delta L and the maximum gap Delta E, the theoretical gap Delta S between the target end face of the mounting base and the lathe bed body is obtained as Delta S=(Delta E-Delta L) / 2; adjusting the mounting base to a third target position to make the transmission axis of the worm gear and the worm coincide; the distance between the target end face of the mounting base and the lathe bed body is Delta S at the third target position, and the application has the advantages of reducing the operation difficulty of transmission axis coincidence adjustment.
