【 摘 要 】

Gear hones are used for finish machining of hardened gear teeth lateral faces applying the generating method. In service, due to penetration of abrasive grains into metal, wear and running-in of the tool material, availability of contact deformation and elastic strain of gear-hone teeth, especially in the case of elastic binding agents, the tooth contact takes place not in a point, but in an ellipse area. The gear hone tooth deformation value depends on the contact point position along the tooth height; it increases by ten folds from the lower contact point to the top. A model of engagement of gear hone teeth and parts that enables simulating the mobility of hone teeth against gear teeth due to elastic deformation of the former and making allowance for specific sliding variations in the contact point is suggested. Besides, the model tooth symmetry axis turns by a certain angle proportional to the deformation value, the contact points shift, and the design values of the center-to-center distance, total length of transmission, curvature radii, and profile pressure angles change. This allows to consider the influence of elastic strain for calculation of gear hone geometrics and therefore affect the metal removal intensity, as well as quality and accuracy of treatment.
