ABSTRACT:
Gear teeth of the gear being worked are machined by rotating the gear with a gear-type machining tool moved radially into tangential contact with the gear being worked. The relative of rotation rates of the gear and the tool are determined by the number of gear teeth in both the gear and the tool. The tooth width of the gear-type machining tool, which may be a worm gear, is less than the finished measurement of the tooth space of the gear being worked. When the gear-type tool reaches the prescribed manufacturing center distance, it is contiguous with the gear from one frontal face to the other. Two flanks of the gear are machined by feeding either the gear or tool in a direction perpendicular to the radial direction of movement so that the teeth of the tool can machine the gear tooth flanks as the gear and the tool rotate. First one flank of each tooth of the gear may be machined and then, by reversing the movement direction, the other flank of the tooth is machined. Alternately, both flanks of each tooth of the gear may be machined simultaneously by using two tools.
