Abstract
A rotary to linear actuator, comprises a drive crankarm that rotates in a first axis of rotation; a first and second gearset connected to the drive crankarm through a second crankarm; and a piston captured between the first gearset and the second gear set, wherein the first and second gearsets rotate a crankarm connected to one end of the piston, wherein the piston is caused to move linearly upon rotation of the crankarm.
Claims20
A rotary to linear actuator, comprising:
- a drive crankarm that rotates in a first axis of rotation;
- a second crankarm connected to the drive crankarm, wherein the second crankarm rotates in a second axis of rotation radially distant from the first axis of rotation;
- a first pinion gear connected to the second crankarm, wherein the first pinion gear rotates in the second axis of rotation, and the first pinion gear is intermeshed with a stationary first ring gear;
- a third crankarm connected to the second crankarm through a rod journal radially distant from the second axis of rotation, wherein the third crankarm rotates in the second axis of rotation, and the rod journal passes through a third axis of rotation;
- a second pinion gear connected to the third crankarm, wherein the second pinion gear rotates in the second axis of rotation, and the second pinion gear is intermeshed with a stationary second ring gear;
- a piston connected to the rod journal, wherein the piston travels in a reciprocating linear motion as the drive crankarm is rotated.
3 more elements
A rotary to linear actuator, comprising:
- a drive crankarm that rotates in a first axis of rotation to rotate a second axis of rotation;
- a first and second gearset connected to the drive crankarm through a second crankarm, wherein the second crankarm has a center of rotation at the second axis of rotation;
- a piston captured between the first gearset and the second gearset, wherein the first and second gearsets rotate the second crankarm and a third crankarm, the second and third crankarms are connected to one end of the piston, wherein the piston is caused to move linearly upon rotation of the drive crankarm.
