Abstract

The invention discloses a tool for machining an inner gear. The tool is an involute spline broach. A front handle part (1), a neck part (2), a transition taper part (3), a front pilot part (4), a cutting part (5), a calibration part (6) and a rear pilot part (7) are sequentially arranged on the broach from front to rear. A rear handle part (8) is further arranged at the tail of the broach. The mode number of the involute spline broach ranges from 0.15 to 16. The number of teeth of the involute spline broach ranges from 21 to 39. The pressure angle of the involute spline broach ranges from 23 degrees to 31 degrees. According to the tool for machining the inner gear, the involute spline broach is utilized to machine the inner gear, and parameters of the involute spline broach are optimized, so that the better machining effect of the involute spline broach can be achieved. Machining accuracy of the tool for machining the inner gear is better than accuracy of a tool manufacturing through a general method, machining efficiency of the tool is improved by 27% compared with the prior art, the tool is integrally formed, and machining cost is greatly reduced.
