Abstract

1512027 Toothed gearing LES BRONZES D'INDUSTRIE and P LAJOYE 11 June 1975 [12 June 1974] 24953/75 Heading F2Q A worm speed reducer comprises two worms 2, 3 of the same diameter, one having a righthand thread and the other having a left-hand thread, each worm meshing respectively with an associated gear ring, the gear rings having the same pitch diameter and being integral with a single wheel 15. In a modification, shown in Fig. 7, a wheel 22 is provided with a multiple series of herring-bone teeth 23 to 27 which mesh with worms 17 to 21. (For Figures 3 and 7 see next page.)
