A gear mechanism arrangement includes an axial bearing apparatus and a shaft mounted rotatably in the axial bearing apparatus. The shaft is fixedly coupled to a first mechanical coupling point and a second mechanical coupling point, the first mechanical coupling point configured to engage a gear stage and the second mechanical configured to engage a movement converter. The movement converter is configured to convert between a rotational movement and a longitudinal movement of the gear mechanism arrangement. The axial bearing apparatus is configured to transmit a force which acts axially on the shaft to a stationary part of the gear mechanism apparatus arrangement. The axial bearing apparatus is further configured such that active bearing friction is dependent on a rotational direction of the rotational movement and differs for each of first and second rotational directions of the rotational movement.
A gear mechanism apparatus having an axial bearing apparatus, having a shaft (11) which is mounted rotatably in the axial bearing apparatus, having a first mechanical coupling point (20) for a gear stage (2) and having a second mechanical coupling point (21) for a movement converter (22, 23), it being possible for a rotational movement of the gear mechanism apparatus (1) to be converted by the movement converter (22, 23) into a longitudinal movement or else, conversely, a longitudinal movement to be converted into a rotational movement of the gear mechanism apparatus (1), and it being possible for a force (F) which acts axially on the shaft (11) to be transmitted via the axial bearing apparatus to a stationary part (16) of the gear mechanism apparatus (1), characterized in that the axial bearing apparatus is configured because of its construction in such a way that active bearing friction is dependent on the rotational direction of the rotational movement and is different for the two rotational directions of the rotational movement.
