Abstract: 744,645. Variable-speed gear. CASCAJARES, F. D. Aug. 18, 1953 [Aug. 20, 1952], No. 22778/53. Class 80(2) A planetary gear 5, 11 controlled automatically in response to speed and load by the gyroscopic resistance of a flywheel 6a, has the flywheel universally mounted on a gimbal ring 3 on, and for rotation with, an input shaft 1, and caused to oscillate about a transverse axis by relative rotation between the input shaft 1 and a reaction element 5 of the planet gear acting through an internal circumferential guide-surface 10a, concentric with and carried by the flywheel offset from the plane A of its universal mounting, such oscillation setting up a precessional force opposing rotation of the reaction element. In Fig. 1 an output shaft 13 carries an internally bevel-toothed ring 11, tracked by the bevel reaction planet 5, secured to an inclined shaft 4 universally and centrally connected through a gimbal ring 2 with the input shaft 1, and journalled in an eccentric inclined bore in a ring 14 bearing in the driven ring 12. The flywheel 6a is additionally supported through a bearing 8 in a non-rotary gimbal ring 9, and its offset internal circumferential guide-surface 10a has a predetermined small clearance from a bush 7 free on the inclined shaft 4, so that the conical planetation of the shaft 4, caused by relative rotation between input and output shafts 1, 13, oscillates transversely the rotating flywheel 6a, producing a gyroscopic resistance to planetation which increases with speed to give continuously increasing speed ratios tending eventually to solid drive. Modifications are as follows. Fig 2 (not shown) mounts the bearing 8 directly on the guide-ring 10a. Fig. 3 (not shown) eliminates the non-rotary gimbal ring 9, leaving the flywheel supported only by the shaft universal joint 3. Fig. 4 (not shown) replaces the two element bevel train 5 by a three element spur train having sun and ring on-the input and output shafts respectively and a planet carrier with an eccentric boss carrying the flywheel-oscillating bush 7. Fig. 5 (not shown) modifies Fig. 4 by using stepped planets meshing input and output suns. A neutral position may be provided by moving a coned member between the bush' 7 and flywheel cone 10a to prevent tilting of the flywheel, and direct-drive lock may also be provided.
