Embodiment Construction

[0045] In order to have a clearer understanding of the technical features, objects and effects of the present invention, the specific embodiments of the present invention will now be described with reference to the accompanying drawings. Wherein, the same parts use the same reference numerals.

[0046] First, some technical terms in this article are explained as follows:

[0047] Worm inlet: The worm is the active part, and the tooth surface first contacts the end of the worm gear.

[0048] Worm outlet: The worm is the active part, and the end of the tooth surface that is finally out of contact with the tooth surface of the worm gear.

[0049] Displacement of center distance: The center distance of the worm and the worm gear is different, but it does not change during processing.

[0050] Transmission ratio displacement: The transmission ratio of the worm and the worm gear is different, but it does not change during processing.

[0051] Variable center distance: When proces...

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...
