Abstract: A wobble drive in an axial piston machine, particularly the axial piston pump of a high-pressure cleaning device, having a wobble body (1) rotatable around an axis of rotation (D) and a wobble plate (2) driving with its front side at least one piston (10a) positioned parallel to the axis of rotation D, a roller bearing (3) positioned between the wobble body (1) and the wobble plate (2) exhibiting a bearing axis inclined to the axis of rotation (D). In order to insure even at elevated rotary speeds of the wobble body (1) and thus also of the rolling bodies (6) that the rolling bodies (6) are securely held in their races (4,5) in spite of the elevated centrifugal forces acting on them, it is proposed that the wobble plate (2) be provided with a rim (7) overlapping the wobble body (1), with the rolling bodies (6) being positioned between the rim (7) and the wobble body (1).

Abstract: An axial piston machine, in particular an axial piston pump of a high-pressure cleaning device, includes a wobble drive having a wobble member rotatable about an axis of rotation, and a swash plate rotatably supported by the wobble member and extending at an inclination with respect to the axis of rotation. The swash plate interacts on one end face thereof with at least one piston. For simplification of the assembly of an axial piston machine, the wobble member is so configured as to have a conical portion flared in the direction of the swash plate and formed with a ball race for a ball bearing.
