A device for converting linear motion to rotary motion or vice versa employs at least two bearing members mounted for rotation about a crankpin of a rotatable crank, each bearing member being in constant engagement with its own individual bearing surface. A shuttle, which is mounted for reciprocating linear movement, carries the bearing surfaces, which are located on opposite sides of the crankpin and are offset relative to each other. Because the bearing members are in constant engagement with their associated bearing surfaces, the linear motion of the shuttle is continuously converted into the rotary motion of the crank or vice versa. |
