In order to more accurately reflect the real contact stress on the tooth surface of beveloid gear

this paper constructs the tooth surface contact coefficient of beveloid gear

and verifies its rationality. Based on fractal contact theory and Hertz contact theory

a contact model of beveloid gear is established

which comprehensively considers the parameters such as gear tooth surface roughness

elastic deformation of contact point and material characteristics. The effectiveness of this method is contact strength of beveloid gear

which is compared with the finite element calculation results by calculating. The relation between load and area during gear meshing is obtained through fractal theory

and four basic parameters are simulated to analyze the effect of fractal contact model. The results show that the accuracy of fractal contact model is verified by numerical simulation and analysis of the relation between actual contact area and load. This paper is based on the finite element theory

Hertz contact theory and fractal theory

the tooth surface contact strength of beveloid gear is compared and analyzed

the correctness of calculating the contact stress of beveloid gear by fractal contact model is verified. The establishment of this model provides a certain theoretical basis for the design and strength check of beveloid gear.
