Disclosed is a cycloidal transmission. The cycloidal transmission comprises a housing (02) with a cylindrical inner housing wall, (21) which is arranged concentrically about a cylinder axis (20) and which is provided with an inner toothing (22). The cycloidal transmission further comprises an input shaft (03), which is rotatably mounted about the cylinder axis (20) and which has at least two eccentric sections (31) of equal eccentricity (32), which are arranged so as to be rotated regularly about the longitudinal axis (30) of the input shaft (03). The cycloidal transmission also comprises an output shaft (04), which is rotatably mounted about the cylinder axis (20), wherein the longitudinal axes (30, 40) of the input shaft (03) and of the output shaft (04) correspond to the cylinder axis (20). The cycloidal transmission further comprises at least two cycloidal discs (05, 06, 07), of which each cycloidal disc (05, 06, 07) is rotatably arranged about a pertaining central axis of rotation (50, 60, 70) on an eccentric section (31) and has an outer toothing (51, 61, 71) that meshes with the inner toothing (22). The axis of rotation (50, 60, 70) of each cycloidal disc (05, 06, 07) is offset to the cylinder axis (20) by the eccentricity (32), wherein the diameter of the cycloidal discs (05, 06, 07) is dimensioned such that the outer toothing (51, 61, 71) thereof engages with the inner toothing (22) in a direction, in which the eccentric section (31) on which a cycloidal disc (05, 06, 07) is arranged, momentarily points. On the other hand, the outer toothing (51, 61, 71) is free from engagement with the inner toothing (22) in the opposite direction, wherein the cycloidal discs (05, 06, 07) each have reference surfaces (53, 63). The cycloidal transmission additionally comprises at least one output member (08), which is rotatably mounted about the cylinder axis (20) and which is operationally connected to one or a plurality of reference surfaces (53, 63) of at least one cycloidal disc (05, 06, 07) such that the movements of one or a plurality of cycloidal discs (05, 06, 07) are converted into a rotational movement of the output shaft (04) during their rolling in the housing (02). The cycloidal transmission (01) is characterised by an even transmission radio i. The outer toothings (51, 61, 71) of the cycloidal discs (05, 06, 07) each have an even number of teeth. The inner toothing (22) of the housing (02) has a number of teeth that is greater or lesser by a (whole) number Z, N+Z or N-Z. |
