标准渐开线花键孔一般采用标准渐开线花键孔拉刀加工,但在单件或小批试制中,对于非标准渐开线花键孔的制造,则常根据各厂实际及现有加工条件,自行设计与制造单齿成形插刀。渐开线单齿插刀齿形如图1所示。以刀齿中心线oy为纵坐标,分别计算出不同半径R_x处的坐标点M_x,可取10～20个坐标点,再用曲线板光滑连接即成。一、坐标点计算步骤和方法 (1)求齿形任意圆半径上的压力角α_x。
Standard involute spline hole generally use the standard involute spline hole broach processing, but in a single piece or a small batch of trial, the involute spline hole for the manufacture of non-standard, often according to the actual plant and the present A processing conditions, their own design and manufacture of single tooth forming knife. Involute single-tooth knife tooth shape shown in Figure 1. Taking the center line oy of the cutter as its ordinate, the coordinate points M_x at different radii R_x are respectively calculated, preferably 10 to 20 coordinate points, and then the smooth connection is made by the curve plate. First, the coordinate point calculation steps and methods (1) Find the tooth shape of any radius on the pressure angle α_x.
