Abstract: 554,874. Gear cutting. POWER PLANT CO., Ltd., and PIETRKOWSKI, H. A. Feb. 25, 1942, No. 2472. [Class 83 (iii)] [Also in Group XXIII] In a method of and apparatus for grinding gears or gear-shaped cutters, a main cam is employed to produce true involute gear profiles and an auxiliary cam to produce modifications of the profiles. The work 17 is mounted on a spindle 14 carrying a dividing-plate 18 coacting with a locking-bolt 21 secured to a collar 12 on a hollow vertical shaft 11 carried in a bearing housing 10, a thrust-bearing 13 being located beneath the collar 12. A cover plate 16 retains the work-spindle in position. The bearing housing is carried in a slide 9 moving on guides 7. The shaft 11 carries a main cam 19 and a gear 22 engaging a rack 23 on one side of a slide 25 actuated by adjustable crank mechanism 27. The cam engages a follower 28 on a sliding member 45 engaging a lever 37 pivoted at 43 and coacting at its other'end with a plunger 40 actuated by an auxiliary cam 29. The latter is mounted on a shaft 31 carrying a pinion 30 engaging a rack 24 on the slide 25. The followers 28, 39 are held against their respective cams by a weight on a cable secured to the housing 10. In order to form true involute gears by rolling the work 17 past a grinding-wheel 55 the abutment 28 is fixed and a cam 19 of constant rise is employed and is designed to impart linear movement to the bearing 10 as the cam rotates as though the gear blank were rolling on its pitch circle. The rotation of the cam is produced by movement of the rack 23 in engagement wich the wheel 22, the stroke of the crank 27 being equal to the pitch-circle movement of the wheel 22, less the linear displacement of the bearing 10. For producing modifications of the involute profile, the auxiliary cam 29 is employed to impart movement to the lever 37 and so alter the position of the abutment 28. The grinding- head mounting comprises compound slides 48, 49 and circular adjustment 50. The slide 49 has a pivot 53 for the adjustment of a bracket which has an angular adjustment 51 for a head on which the grinding-wheel slide is adjustable by screw 52. In this way the grinding-wheel may be set for pressure angle, helical angle, and relief angle.
