Embodiment Construction

[0010] exist figure 1 In the process, first draw the shape of the gear in Autocad, then design the shape of the driving ellipse according to the circumference of the external gear, import it into Solidworks to draw the steel wheel, flex spline and wave generator of the harmonic gear, and then carry out three-dimensional assembly.

[0011] exist figure 2 and image 3 In the process, the three-dimensional assembly drawing is imported into ansys, and the simulation is carried out to observe the interference situation and the force situation in the meshing process, and combine the two comparative analysis, and then improve the tooth shape design and material selection of the harmonic gear.

Abstract

The invention provides design and interference simulation of a harmonic gear, and relates to the improvement of design analysis of the harmonic gear. The appearance of the harmonic gear is drawn up in Autocad, the shape for driving an ellipse is designed according to the perimeter of an external gear, and the interference situation is simulatively watched through three-dimensional assembly of solidworks and ansys software, so that the deformation and meshing interference situation of the gear can be exactly watched, the stress situation of the gear in the meshing process can be watched, and the changed shape or materials needing for the gear can be better analyzed.

Description

Technical field [0001] Harmonic gear design and interference simulation involves an improvement of harmonic gear design analysis. Background technique [0002] The effect of harmonic gear transmission is remarkable, but there is no simple and effective method for design analysis. Contents of the invention [0003] The technical scheme adopted in the present invention is: draw the profile of the gear in Autocad, then design the shape of the driving ellipse according to the circumference of the external gear, and watch the interference situation through the three-dimensional assembly of solidworks and the simulation of ansys software. [0004] The beneficial effect of the present invention is to provide a method for designing a double-arc gear, and the circular flexible spline is expanded by an elliptical wave generator. Compared with the traditional design method of pasting the tooth shape on the ellipse one by one, this method can directly, quickly and accurately observe ...
