TREATMENT broaches involute splines

摘要

Broach for machining involute splines comprises a body (1) with a shank (2) formed on it and the cutting part (3). The cutting portion (3) formed by the generating circuit and comprises teeth (4) to correct the profile. Broach made modular, and further has at least two cutting disc (5), comprising lapping the teeth (6) formed on the profile scheme. Wheels (5) are oriented relative to each other by means of eccentrics (7) placed in holes (8) of one disc and entering into the grooves (9) on the other disk and the guide sleeve (10). The guide sleeve (10) rigidly fixed to the housing (1) and presses the cutting wheels (5) for generating broach portion in the axial direction. A total feed tooth honing selected from the following conditions: Where S _z - feeding tooth generator part broach mm; δ - undercut angle (between the cutting edge and the theoretical tooth generator side surface of the recess); β - the angle of the teeth profile generator. Fixation of guide sleeve 10 carried on the housing 1 by means of fastening mechanism 11. By eliminating the step shape of the side surfaces of the slots was increased quality of the machined surface. 9 yl.
