Abstract: A rotatable drive shaft in the swash pump or turbine for liquids is supported by one bearing at each end. An integrated motor or dynamo uses the same two bearings. The compound first bearing supports a slanted section of the drive shaft placed inside the inner swash sphere, and transfers rotational power to the attached nutatable swash plate. The second bearing confines rotation of the drive shaft in a defined axis. Either one of the bearings is made to prevent axial movement of the drive shaft, preventing swash pump misalignment. A resilient drive, and an immersed pump are described.

Abstract: A method of manufacturing a pin (roller) holding ring for a gear mechanism in which external gears (5a, 5b) are meshed internally with an internal gear (20) comprising a pin (roller) holding ring (110) having semi-circular pin (roller) holding holes in the inner peripheral side and pins (rollers) (11) close-fitted rotatably in these pin holding holes, the method comprising the steps of drilling fully circular pin holding holes (113a) in a ring base material before the inner diameter DA of a pin holding ring base material (151) is machined to a finish diameter, and expansion-machining the inner diameter of the pin holding ring up to a finish diameter after the inner surfaces of the pin holding holes have been surface-finished by a roller burnishing machining so as to provide the pin holding ring having semi-circular pin holding holes, whereby the sliding rotation of the pins in the pin holding holes can be improved.

An expeller (26) is arranged eccentrically in the inner space (22). A helical sealing element (34) is provided between the expeller (26) and an inner wall (38) of the housing (10) for forming at least one crescent-shaped conveying space. The housing (10) or the expeller (26) are connected to a drive device (44) for producing a relative rotary movement between the housing (10) and the expeller (26). According to the invention, the vacuum pump is configured as a dry-running vacuum pump.
