Abstract
The compressor can be classified a dynamic type and a positive displacement type. In the case of the high discharge pressure, the axial flow compressors are used without the pulsatory motion. While, the reciprocating compressors that one of the positive displacement type have the advantage of the higher discharge pressure. A slider-crank mechanism used in a reciprocating compressor is valuable to convert mutually between the linear and rotational motions. However, there is a problem about friction loss and the vibration caused by the force reacting on the piston from the cylinder side wall, during the piston stroke. This phenomenon shortens the lifetime of the compressor. The side force prevents the driving with the high velocity revolution, so a field of use is limited. When the reciprocating compressor can be driven with the high velocity revolution without the vibration and pulsatory motion, a new type of the compressor is realized to transport the air with high discharge pressure and the large volume. This type of compressor is expected to be applied to the field of manufacturing and welfare. In this paper, we try to design in order to eliminate the side force from the compressor, to realize the low vibration compressor using a orthogonal double-slider joint mechanism. We structured the kinematic model and verified the characteristics of the compressor analytically.
