Study of sliding parameters in engagement of gear hone teeth and processed parts with consideration of elastic deformation

Abstract

Abstract Gear hone is a special tool used for roll finishing of lateral faces of hardened gear teeth. Over time, penetration of abrasive grains into the metal, wear and breaking in of the hone material, contact and bending deformation of the hone teeth, especially if an elastic binding agent is used, lead to changing the tooth contact geometry, i.e. a point contact turns into an elliptical contact. The gear hone tooth deformation is a function of the contact point height, i.e. for contact points closer to the tooth top, the deformation is many times larger than that occurring for contact points closer to the tooth bottom. It affects the specific sliding ratio between the meshing hone and the workpiece. Meanwhile, slight equalization of the specific sliding along the tooth height occurs. Comparable deformations, errors and metal removal rates applicable to the gear hone and the workpiece would contribute to the effectiveness of the error reduction measures. The elasticity of the tool’s composite material must be duly considered in calculating the geometry, selecting the compound composition and assessing the applicability of gear hones.
