Abstract

296,809. Farrelly, M. M. June 8, 1927. Variable-speed epicyclic gearing comprises planetary worms 8, Fig. 4, which are also wormwheels. They are wormwheels in respect of spiral grooves 18 which are engaged by spiral teeth 16, Fig. 2, inside an annular driving element 2. They are worms with respect to a toothed wheel 9, Fig. 1, which is variably driven. The planets 8 are supported loosely and tangentially on the edge of a loose intermediate disc 7. Roller bearings are shown at 11. Friction in the rapidly rotating worm gearing is effective in producing a drive variable with the load. The action may be assisted or controlled by pressing the wheel 9 against the disc 7 by applying a thrust to a collar 26. A train 23 is for reversed driving. A modification is described comprising a one-way clutch.
