Abstract

The present disclosure relates to an eccentric gearing having a first gearing element, which has a first axis and an outer contour having at least one cam, and having a second gearing element, which has a second axis which is constantly held eccentrically in relation to the first axis. The first gearing element is rotatable relative to the second gearing element, and the second gearing element is supported on the outer contour of the first gearing element such that a rotation of the first gearing element effects a rotation of the second axis of the second gearing element about the first axis. The first gearing element has a number N of cams protruding radially, and uniformly distributed in the circumferential direction, in relation to the first axis. The second gearing element is supported at N+1 contact points of the first gearing element, wherein N is at least two.

Dependent claims

Eccentric gearing comprising:

a first gearing element, which has a first axis and an outer contour having at least two cams protruding radially in relation to the first axis;
a second gearing element, which has a second axis which is constantly held eccentrically in relation to the first axis, wherein the first gearing element is mounted in a rotatable manner about the first axis relative to the second gearing element, and wherein the second gearing element is supported on the outer contour of the first gearing element such that a rotation of the first gearing element about the first axis will effect a rotation of the second axis of the second gearing element about the first axis, and
wherein the at least two cams is a number N of cams, which cams are arranged so as to be distributed uniformly in a circumferential direction in relation to the first axis, wherein the second gearing element is supported at N+1 point contacts on the outer contour of the first gearing element.

Dependencies are inferred from the claim text.
