Abstract: A housing (02) with a cylindrical inner housing wall (21) that is disposed concentrically about a cylinder axis (20) and is provided with an inner set of teeth (22). It further includes an input shaft (03), supported rotatably about the cylinder axis (20), having at least two eccentric portions (31) of identical eccentricity (32) that are disposed rotationally about the longitudinal axis (30) of the input shaft (03). Moreover, it includes an output shaft (04), supported rotatably about the cylinder axis (20), and the longitudinal axes (30, 40) of the input shaft (03) and output shaft (04) coincide with the cylinder axis (20).

Abstract: A transmission having a hollow-cylindrical main body having end faces, which has internal toothing and a rotation axis and in which a driven input member and an output member are rotatably mounted, wherein the output member comprises two rotating bodies, which are non-rotatably connected to one another and have a circular cross-section transversely to the rotation axis. The rotating bodies are provided with spacers, a gear wheel and a device for converting planetary movements of the gear wheel into rotational movements of the output member being disposed between the rotating bodies. The device has a ring shape, the two end faces of which have two guides with central axes, one of whose end face extend perpendicularly to an axial plane of the transmission, while the other end face extend parallel to the axial plane, and the ring has continuous, axially oriented openings through which spacers pass without contact.

Abstract: The invention relates to a gear system, particularly an epicyclic gear system, with a basic member (40) with at least one rotatably mounted output member (50), and with an annular running space (1), formed in the bearing region of the output member (50), and with bearing surfaces (40e, 44b, 59a, 59b) for cylinder-like roller members (47, 47'). Some roller members (47) are aligned with respect to the axis of rotation (40a) of the gear system substantially axially, while the other roller members (47') are positioned substantially radially (FIG. 1).

Abstract: The invention relates to a gear system with at least one wheel (40) with an internal toothing (41), with at least one output member (50) mounted to rotate with respect to the wheel (40), and with an input shaft (10) with at least one eccentric portion (17) on which there is rotatably mounted at least one wheel (30) with external toothing (33) meshing with the internal toothing (41), when there are two or more wheels (30, 30) at least one wheel (30) being located between the output members (50, 50). Between the wheel (30) and the output member (50) there is located a member (70) transforming the planetary movement of the wheel (30) into rotary movements of the output member (50), said wheel (70) being located to be displaceable with respect to the wheel (30) and the output member (50), and executing transverse movements (FIG. 2e) with respect to the axis of the input shaft (10).
