Manufacturing method of worm gear pair

Abstract

The invention relates to a manufacturing method of a worm gear pair, comprising steps as follows: step A, optimizing and simulating a planar secondary enveloping ring-surface worm gear pair, which comprises specific steps as follows: (A1) inputting basic parameters of the worm gear pair, such as the central distance a, the head number of the worm z1, and the gear number of the worm z2; (A2) leading the data of the previous step into a target function formula to perform parameter calculation; employing iteration and approximation of a complex method in the target function calculation process to obtain geometric parameters and technological parameters of the ring-surface worm gear pair, wherein the geometric parameters and the technological parameters are configured in a matched manner; and the target function formula is represented by FORMULA in which f(x) is a target function, Ai is a weighting coefficient, epsilon is a convergence coefficient, and K is an optimized parameter; and (A3) generating a three-dimensional graph of the worm; affirming that the worm has no undercutting and gear tip sharpening according to the three-dimensional graph of the worm; and step B, separately processing and manufacturing the worm and the gear of the worm gear pair according to the geometric parameters and the technological parameters.

Description

technical field [0001] The invention belongs to the category of mechanical transmission, and relates to a method for manufacturing a worm pair, in particular to a method for manufacturing a plane secondary enveloping worm pair. The invention can be applied to a worm drive device, especially a pressing device of a wide and heavy plate rolling mill, and has a pressing effect on the rolls of the rolling mill. Background technique [0002] Worm drive is a commonly used transmission device in mechanical equipment. The toroidal worm drive has the advantages of large bearing capacity, high transmission efficiency and long service life. Usually, a worm pair with a center distance greater than 500mm is called a worm pair with a large center distance; a worm pair with a number of worm heads greater than 2 is called a multi-head worm pair. [0003] In the initial stage, the application scope of the torus is basically limited to the original linear enveloping toroidal worm. The basic f...
