Abstract

Two shafts (2, 3) project co-axially from the opposite ends of a housing (1) containing a gear train. The gearing may be of the planetary type. The rotation of one of the shafts provides a reduced rotation of the other shaft, and the reverse action produces multiplication. The housing (1) may contain a group of planetary gear wheels (6, 9, 10, 12). The housing (1) may incorporate an internally toothed crown-wheel (6), while one shaft (2) terminates in a plate (7) supporting two planetary pinions. The other shaft extends in the form of a central pinion which engages the two planetary pinions (10, 11).
