Abstract
The present invention relates to an assembly for translating linear movement to rotary motion, and in particular to an improved relationship between a linearly reciprocal member such as a yoke structure and associated piston, and a rotatable shaft such as a crank shaft. The invention could be used in any application where motion is to be translated from rotary to linear or vice versa, such as in compressors for example.
Claims20
An assembly for translating linear motion of a linearly moveable member to rotary motion of a rotatable shaft, said assembly characterised by:
- a yoke structure associated with said linearly moveable member, said yoke structure including an inner surface;
- a leverage means associated with the rotatable shaft, the leverage means including at least one arced surface adapted to contact the yoke structure inner surface, the leverage means surface and yoke structure inner surface being dimensioned such that for at least a period of each revolution of the shaft, a constant contact force is transferred from the linearly moveable member to the shaft in a rocking motion between the two surfaces.
