20140326129 | Methods and Apparatus for Adjusting Actuator Output Torques - Methods and apparatus for changing actuator output torques are disclosed. An example method includes decoupling a first end cap from a body of an actuator. A first spring assembly is positioned within a first outer chamber defined by the first end cap and the body. A first end of the first spring assembly is positioned adjacent a surface of a first piston. A second end of the first spring assembly is positioned adjacent the first end cap when the first end cap is coupled to the body. The method includes positioning a first spacer within the first outer chamber and coupling the first end cap to the body. The first spacer changes a distance between the first and second ends of the first spring assembly when the first end cap is coupled to the body to change an output torque of the actuator. | 11-06-2014 |
20130337958 | ELECTRIC MOTOR TORQUE TRANSFER DEVICE AND SENSOR - A force transfer apparatus includes a housing, a shaft, a plunger, a retention plate, and a force sensor. The housing defines a cavity and a sidewall with an aperture. The shaft is supported in the cavity for rotation about a first axis that is a longitudinal axis of the shaft. The plunger is disposed in the aperture and has a first and second ends. The first end is operably coupled to the shaft such that the plunger can slide along a second axis that is transverse to the first axis in response to rotation of the shaft. The retention plate is fixed to the sidewall outside of the cavity adjacent to the aperture. The force sensor is disposed between the second end of the plunger and the retention plate. As such, the force sensor can detect the amount of force applied to the plunger by the rotation of the shaft. | 12-19-2013 |
