Design of Shaving Cutter with Unequilateral Profile

doi:10.3901/JME.2018.19.034

Abstract

Abstract: In the process of gear shaving, the single point contact occurs near the pitch circle in the meshing cycle, which is the three-point meshing area, is one of the important reasons for the profile-concave-error of the shaving tooth. Based on the principle of negative displacement shaving and balance shaving, the unequilateral profile design of the negative displacement shaving cutter is carried out by reducing the maximum radius of curvature of the secondary working face so that the main and auxiliary working surfaces are simultaneously engaged and balanced shaving is achieved. The three-point meshing area near the pitch circle will be effectively eliminated and the situation that the region of the teeth between the meshing force is not uniform will be improved. Taking the amplitude of the transmission error curve as the dimension, the unequilateral profile shaving cutter and the negative displacement shaving cutter are compared and analyzed. The results show that the unequilateral profile shaving cutter can optimize the negative displacement shaving and balance the shortcomings which is difficult achieved in the shaving conditions, so that the meshing force in the process of meshing tends to be smooth, and the balanced shaving is achieved, and the amplitude of transmission error is reduced. A new technical idea is provided to eliminate the profile-concave-error of the shaving tooth.

Key words: balanced gear shaving, concave-error, gear shaving, negative modified shaving, transmission error, unequilateral profile shaving cutter
