Abstract
A hydraulic motor is disclosed. The hydraulic motor includes a first toothed wheel and at least one second toothed wheel configured to at least selectively engage the first toothed wheel. The hydraulic motor also includes at least one hydraulic actuator and at least one linkage operatively disposed between the at least one second toothed wheel. The at least one linkage configured to transfer a reciprocal motion of the at least one hydraulic actuator to a rotary motion of the first toothed wheel.
Claims20
A hydraulic motor comprising:
- a first toothed wheel;
- at least one second toothed wheel configured to at least selectively engage the first toothed wheel;
- at least one hydraulic actuator;
- at least one linkage operatively disposed between the at least one second toothed wheel and configured to transfer a reciprocal motion of the at least one hydraulic actuator to a rotary motion of the first toothed wheel.
A method of converting linear motion into rotary motion comprising:
- selectively supplying pressurized fluid to a first actuator to selectively produce a first reciprocal motion;
- transferring the selectively produced first reciprocal motion to a first toothed wheel via a first linkage;
- selectively locking the first toothed wheel to the first linkage via at least a first sprag;
- and
- transferring the selectively produced first reciprocal motion to a second toothed wheel via the first toothed wheel to rotate a second toothed wheel about an axis.
A motor comprising:
- a first hydraulic motor operatively connected to an output;
- a second hydraulic motor operatively connected to the output;
- each of the first and second hydraulic motors including:
- a first toothed wheel configured to rotate about an axis;
- a first hydraulic actuator configured to selectively produce a reciprocating movement;
- a second toothed wheel;
- and
- a linkage operatively disposed between the first hydraulic actuator and the first toothed wheel and configured to selectively urge the second toothed wheel toward the first toothed wheel.
