Abstract: Oldham couplings are disclosed, for example, for use in electric camshaft adjusters. The Oldham coupling may include a first outer connecting disk and a second outer connecting disk having axes of rotation extending parallel to each other and a central connecting disk including one or more through-bores. One or more connecting elements may couple the first outer connecting disk to the central connecting disk via the through-bore(s). A sleeve may be arranged in the through-bore(s) such that the connecting element(s) contacts the sleeve and wear of the central connecting disk is reduced. For example, the sleeve may prevent direct contact of the connecting element(s) with the central connecting disk, such as by a spacer or flange. The sleeve may be made of metal, while the central connecting disk may be plastic or metal.
