Embodiment Construction
[0039] The present invention includes a method and apparatus for machining the tooth profile of an internal gear using a drum worm tool.
[0040] Among them, including a method of machining the tooth profile of an internal gear using a drum-shaped worm tool, see Figure 1a , 1b , 1c, 2a, 2b, 2c. The specific steps of the method are as follows:
[0041] Step 1: Design a flat or short drum-shaped worm tool, such as Figure 1c as shown in item 02 or Figure 2c Shown in 02'. The worm grinding wheel can be made as a single-head or multi-head worm, and the worm is located on an annulus, and the radius of the parent circle of the annulus is Figure 1c or Figure 2c The pitch circle radius R0 of the imaginary gears C1 and C2 in . In the figure, the cross-sectional shape of the gear teeth on C2 is the shape obtained by rotating the cross-section on C1 by half the pitch angle (when the worm is a single-head worm) or multiple half-pitch angles equal to the number of worm heads.
