Abstract

A wobble plate engine (20) includes a wobble plate assembly (26) having a wobble plate (58) that rolls against truncated cone portions (42) of a housing (22) and has an inner extremity (60) rotatably supported by an axially inclined annular bearing (49, 49′) on a spherical member (46) of the wobble plate assembly so as to rotate a shaft (24) during the wobbling motion. One embodiment of the wobble engine (20) includes an oil lubrication system (114) and another embodiment includes antifriction roller bearings (220) that support the wobble plate (58) on the spherical member (46), antifriction roller bearings (224) that rotatively support the shaft (24) on the housing (22′) and seals (226) that rotatively seal between the shaft (24) and the housing (22′).
