Abstract

A hub (2) is rigidly torsionwise attached to a leading shaft (1) but free to move axially and radially. A rotary plate (3) is arranged on said hub (2) through a ball bearing (21) and carries a ring (4) provided with four conical transmission surfaces (30, 31). The transmission surfaces (30) of the ring (4) run on surfaces (33) of two rims (7, 8) of a wheel (6) integral with the casing, and the transmission surfaces (31) ran on surfaces (34) of two rims (10, 11) of a second wheel (9) attached to the driven shaft (12) and coaxial with the wheel (6). The distance between the rims (7, 8 and 10, 11) is adjustable. When the driving shaft (1) rotates, the ring (4) effects a slow oscillation motion about the leading shaft (1) and transmits such motion to the wheel (9). The two transmission ranges are offset by 180`. The excentricity is adjustable between a maximum and zero, which allows the obtention of a reduction up to the infinite. A toothing may be provided in the transmission areas. As toothing elements, the ring (4) may be provided with sets of axially free disks and arranged on two rims, which mesh with grooves (71) provided in the surfaces (33, 34). Adjustement devices, preferably in the form of a unit assembly, are used for adjusting the rims (8, 11) and the hub (2).
