Abstract
469,758. Variable-speed gearing. ROES, G. Oct. 25, 1935, No. 29484. Convention date, July 31. [Class 80 (ii)] Relates to variable-speed gearing in which a planetary train is combined with and controlled by a variable eccentric friction - ratchet drive. Spur planets 11, Fig. 1, carried by a spider 3 on a driving-shaft 1 mesh with a sun gear 12 integral with a driven shaft 13 and mesh with an annulus 7, the speed of which is controlled. The annulus tends to run away forwardly, and if it did run away freely, the sun 12 would not be driven. The 1 to 1 drive obtained when the annulus 7 turns solid, is the highest speed transmitted. The speed of the shaft 13 falls as the annulus 7 is driven faster and faster. This accelerated drive passes through discs 2, 5, 6, 21 and the speed of the last disc 21 is raised more and more by moving the intermediate discs 5, 6 to more and more eccentric positions from a control lever 10. There are suitable one-way driving clutches at 4, 4a, 4b in annular recesses such as 5a, and the clutch grip nearest the gear axis always drives by an adjacent pin, such as 4x, in a radial slot, such as 6b, in the next driven disc, in known manner. The last disc 21 thus normally rotates faster than the planet carrier 3, and the disc 21 drives the annulus 7 through an ordinary one-way driving clutch 4c, Fig. 2. The difficulty is to prevent the annulus 7 from running away freely. This is effected by a differential one-way device connecting the driver disc 21 with both the annulus 7 and the carrier 3. The disc 21 has fingers 17 projecting axially between the annulus 7 and the carrier 3, and in the pockets between these fingers there are loose wedges 20 and rollers 19. These rollers 19 and wedges 20 jam so as to prevent the annulus 7 from overrunning while allowing the one-way clutch 4c to drive the annulus at the speed at which the fingers 17 turn. If the annulus 7 be accelerated sufficiently, the driven shaft 13 is brought to rest, and then driven reversely.
