Abstract

The invention discloses an involute internal gear generating instrument which comprises a first external gear, a second external gear, an internal gear and a baseplate, wherein the first external gear and the second external gear are coaxially connected through a fixing shaft, and rotate synchronously; the second external gear is meshed with the internal gear, and drive the internal gear and the first external gear to rotate synchronously; the internal gear is pivoted onto the baseplate; a backing plate is arranged between the first and second external gears in a clamped manner, is connected with the internal gear, and rotates with the internal gear synchronously; the first and second external gears are fixed on the baseplate through a frame body; the position of the frame body can be adjusted through fixing bolts at the two ends of the frame body, and the adjustment stroke is 0.6 time of the moduli of the second external gear and the internal gear; the internal gear is a gear with negative addendum modification. The involute internal gear generating instrument has the benefits of being novel in structure, compact and convenient to operate, and the defects in involute internal gear generating processing and top-cut phenomenon demonstration are overcome.

Description

technical field [0001] The invention relates to an internal gear forming instrument, in particular to an involute internal gear forming instrument. Background technique [0002] Currently, the external gear fanning experiment uses the external gear fanning instrument. Demonstrating the machining principle of external gears and undercutting of gears through Fan Chengyi of external gears; however, there are many differences between internal gears and external gears. For example, internal gears use gear-shaping tools instead of racks. ;Internal gear machining will produce top cutting, not undercutting. Therefore, the present invention develops an involute internal gear fan forming instrument to demonstrate the formation process of the internal gear involute and the phenomenon of top cutting. Contents of the invention [0003] The purpose of the present invention is to provide an involute internal gear forming instrument for solving the problems of the forming process of the...
