A theoretical model of a slipper with multi-lands and multi-grooves for swashplate type axial piston pumps and motors was established, including surface interactions. Further, a numerical simulation was conducted under an unsteady state and mixed lubrication conditions.

Four model configurations were considered: A slipper with a single main land; a slipper with inner and Author: Toshiharu Kazama.

The sealing function prevents the fluid in the displacement chamber from leaking out through the gap to the case, and the bearing function prevents the Author: Ashkan A. Darbani, Lizhi Shang, Jeremy R. Beale, Monika Ivantysynova. This article presents a novel methodology to design swash plate type axial piston machines based on computationally based approach.

The methodology focuses on the design of the main lubricating interfaces present in a swash plate type unit: the cylinder block/valve plate, the piston/cylinder, and the slipper/swash plate interface. These interfaces determine the behavior Author: Rene Chacon, Monika Ivantysynova.

Other readers. Axial-piston pumps — The pistons in an axial piston pump reciprocate parallel to the centerline of the drive shaft of the piston block. That is, rotary shaft motion is converted into axial reciprocating motion. Most axial piston pumps are multi-piston and use check valves or port plates to direct liquid flow from inlet to discharge.

From the energy conversion perspective, the electrical energy is converted into mechanical/forming energy (force and velocity) by motors, pumps, pipes, valves, and cylinders Cited by: Fig. 8: Failure of piston slipper caused by loss of hydrostatic balance H and the force developed is transmitted to the lubricated surfaces of the slipper and swash plate.

It is usually used in respect to aeroplanes and ships though it can be used as the power output from a cars gearbox.

Brake horsepower is the power an engine puts out at the crank and is not subject to 3/5(2). For a vehicle that is travelling at constant speed, from the definition of mechanical energy to move a given distance the energy needed is simply: E=Fxs, where E is the energy, F is the friction force and s is the distance.

This determines the minimum amount of energy the power source must provide and can determine the vehicle's range. magnitude is probably about 7 Ib. per square inch of piston area. The total loss from bearing friction, piston friction and fluid friction in the best ungeared engines is from about to 14 Ib.
