Analysis on Anti-Rotating Mechanism of New Symmetrical Wobble-plate Compressor

摘要

Axial piston compressors may be categorised into two main types: wobble-plate and swash-plate compressors. Wobble-plate compressors differ from swash-plate ones by the use of an anti-rotation mechanism. This mechanism prevents the connecting rods from being tangled together by the wobble-plate from rotating with the rotor. Even though this mechanism enables the wobble-plate compressor to function correctly, it has also setbacks. From a new kinematics model of the wobble-plate mechanism proposed, the effects of the anti-rotation mechanism and related design parameters on the compressor motion were established. The actual loading characteristics on the anti-rotation mechanism were obtained, and then finite element analyses were done to check the structural integrity. Effects of other aspects of this new compressor design on the anti-rotation mechanism were also discussed.
