ABSTRACT:
A wobble yoke mechanism for converting reciprocating motion to rotary motion (or vice versa) in which each of two yokes (4) are connected to beams (3) by bearings (10, 10', 15, 15') having only one degree of freedom. The two yokes are 90.degree. out of phase. An eccentric bearing (15), also having only one degree of freedom, is fitted to or about the nutating shaft (16) and is connected to one end of each of the yokes (3). All the axes of the pairs of bearings pass through a central pivot point (5). The axes of the pistons need not be straight nor need they be parallel with the axis of the crankshaft (12).
