Embodiment 1

[0036] The present invention provides a technical solution: a precise modeling and assembling method of an involute worm gear, and the specific steps of the precise modeling and assembling method of an involute worm gear are as follows:

[0037] S1: Modeling of the worm gear,

[0038] 1) In the part design environment, create a three-dimensional basic entity of the worm gear blank;

[0039] 2) In the environment of wire frame and surface design, a number of model points on the involute line are generated through the regular curve, and the corresponding worm gear involute curve is constructed by using the fourth-order cubic interpolation B-spline curve, and each point on the involute line The regular curve expression about the abscissa x and ordinate y is as follows:

[0040]

[0041]

[0042] where r b is the radius of the base circle, and 50 means that the selection range of the involute is 0°-50°;

[0043] 3) In the part design environment, after a series of operati...

Abstract

The invention discloses an accurate modeling and assembling method for an involute worm gear and worm. The accurate modeling and assembling method for the involute worm and gear comprises the following specific steps that: S1: carrying out worm gear modeling; S2: carrying out worm modeling; and S3: assembling the worm gear and the worm. By use of the method, on the basis of a situation that an involute parameter equation is used for constructing a worm spiral line, the three-dimensional entity modeling of the involute worm is realized, so that the established involute worm is used for finishing the three-dimensional entity modeling of the involute worm in cooperation transmission with the established involute worm, and finally, the three-dimensional entity meshing assembling of the involute worm and the involute worm gear is finished.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission parts, in particular to an accurate modeling and assembly method of an involute worm gear. Background technique [0002] Worm gear transmission is one of the important types of mechanical transmission. It can realize the transmission between two interlaced shafts in space. It has the advantages of large transmission ratio, stable transmission, compact structure and low noise, so it is widely used in various mechanical transmission systems. However, there are problems such as complex process, low efficiency, and error-prone in traditional manufacturing methods. In order to improve product design efficiency, shorten the development cycle and improve the quality of worm gear meshing, the status and role of parametric assembly design of worm gears are particularly important. [0003] At present, the difficulty in parametric assembly design of worm gears lies in the meshing problem bet...
