Abstract: A gear has a gear body made of a first plastic material. The gear body has an axis of rotation, external toothing arranged around an axis of rotation, a centrally located receiving opening, and an intermediate portion located between the external toothing and the wall of the receiving opening. The gear body is fixedly integrally formed on a support body, which is arranged at least partially in the intermediate portion and is made of a second plastic material having a higher stiffness and lower elasticity than the first plastic material, such that surface portions of the external toothing, of the wall of the receiving opening, of the intermediate portion, and of the support body form a substantially flat end face of the gear. The external toothing is helical toothing with teeth which, at least in portions, extend at a helix angle to the axis of rotation.

Abstract: An axial piston machine includes a retraction plate, first apertures of which are each penetrated by an associated sliding shoe. A joint section of the sliding shoe deviates from a circular cylindrical shape such that it has a largest diameter which is spaced apart from the web section, wherein the joint section has a reduced diameter between the largest diameter and the web section compared to the largest diameter. In a reference state, the joint section contacts an inner circumferential surface of the associated first aperture such that a minimum distance is obtained between the web section and the spherical outer surface section, and the inner circumferential surface of the first aperture is adapted to the non-circular cylindrical joint section of the sliding shoe such that the inner circumferential surface and the joint section contact each other in the reference state away from the largest diameter of the joint section.
