Description: |
| Abstract:
Gear-wheels are generated by a rack-tooth cutter so that the working faces of the teeth are of similar curved form, as shown in Fig. 1, whilst the teeth are of correct involute form on all sections at right-angles to the axis of the wheel. The blank a is carried on a table which is given the requisite movements by the gear described in Specification 136,@31 for example. The rack-tool j is carried by the outer of two slides c, d, respectively. The slide c is given a vertical reciprocation by the means described in the aforesaid Specification, for instance, and the outer slide is constrained to move across the face of the slide c by a link e mounted on a pivot f which may be adjusted in position by a screw h. |
