Research on the mechanisms of internal gear honing by use of cone-shape honing wheel with tool tilt angle.

Internal gear is an important transmission component. However, it is restricted by its ring−shaped structure, which hinders the finishing process of the tooth surfaces after the heat treatment. Honing is the most commonly used finishing technique for external gear, but it is inconvenient for internal gear. In this paper, a new type of cone−shape honing wheel is proposed and the honing mechanism for improving the honing performance of the internal gear is studied. First, the mathematical model of the honing technology that employs a cone−shape honing wheel is built, and the merits of the new honing method are discussed. Then, the contact conditions between the honing wheel and the internal gear are analyzed. It is established that the tool tilt angle of the honing wheel has a good effect on the honing velocity distributions. Finally, the simulations of honing and profile measuring of the internal gear by employing the cone−shape honing wheel are carried out, by which the feasibility of the new honing technique is verified.
