  • Patent number: 10480628
    Abstract: An electric actuator to be primarily used on an all-terrain vehicle (ATV) having implements such as snow plow is disclosed. The main purpose of the actuator is to allow the driver to rotate the blade when it is not touching the ground without having to get out of the vehicle. The actuator is composed of a stator assembly and a motor assembly. An electric motor is concealed in the motor assembly and drives a screwed or grooved part that engages the threaded or grooved inner surface of the stator assembly. Rotation of the screwed or grooved part induces a translational movement alongside the longitudinal axis of the actuator assembly. The translation movement induces the elongation or the retraction of the actuator depending on the rotating direction of the electric motor.

    Abstract: An electromechanical strut and method of moving a closure member of a vehicle between an open position and a closed position is provided. The electromechanical strut includes a power drive unit including a motor, a leadscrew, a planetary gearset operably connecting the motor to the leadscrew, and an electromechanical brake assembly. The electromechanical strut further includes a telescoping unit including an extensible tube and a drive nut for converting rotary motion of the leadscrew into linear motion of the telescoping unit. The electromechanical brake assembly is selectively moveable between an engaged state, wherein the leadscrew is prevented from rotating to prevent relative axial movement between the power drive unit and the telescoping unit, and a disengaged state, wherein the leadscrew is permitted to rotate to allow relative axial movement between the power drive unit and the telescoping unit.

  • Patent number: 9051981
    Abstract: A power-off brake for stopping a rotating shaft comprises a solenoid including a coil and armature, an opposing plate axially spaced from the armature, and a ball carrier rotor between the armature and opposing plate. The ball carrier rotor rotates with the shaft and carries spherical balls in recesses angularly space about the shaft. The armature and opposing plate have respective braking surfaces. In one embodiment, at least one braking surface is ramped to urge the plurality of balls radially outward against an internal surface of a surrounding outer race as the armature is forced toward the opposing plate under spring loading when current to the solenoid coil is shut off. In another embodiment, the braking surfaces are not ramped, such that the balls are merely clamped between the braking surfaces upon solenoid deactivation. Increased rolling friction stops rotation of the ball carrier rotor and the shaft without problematic wear.

  • Patent number: 8754557
    Abstract: A bowling machine motor/gearbox conversion and adaptor kit may allow people to reuse their current gearboxes by adapting the components to utilize a new motor that would make the gearbox universal instead of having different motor/gearbox combinations. The adaptor kit may adapt the gearbox portion of the motor/gearbox assembly to allow the gearbox to accept a current, new motor. A person may use the adaptor kit to repair and replace components of a bowling machine's motor and gearbox assembly.

  • Publication number: 20140124688
    Abstract: A rotary actuator suitable for use in a refrigerator ice-dispensing door provides a rotating shaft driven by a DC permanent magnet motor through a gear train and subject to a returning force of an internal spring. The gear train communicates with a switch to reduce current to the motor when a limit of travel is reached and a shunting path is provided around the motor to produce generative braking when power is removed from the motor and the actuator rotates backward to its initial position.

  • Patent number: 8708125
    Abstract: A clutch is provided that includes an annular clutch housing, a driving-side rotor, a driven-side rotor having a control surface, and a rolling element located between the inner circumferential surface of the clutch housing and the control surface. The control surface faces radially outward in the clutch housing. When the driving-side rotor rotates, the rotational driving force of the driving-side rotor is transmitted to the driven-side rotor. When the driving-side rotor is driven to rotate, the rolling element rotates together with the driven-side rotor. When the driving-side rotor is not driven to rotate, the rolling element is held between the inner circumferential surface of the clutch housing and the control surface so as to prevent the driven-side rotor from rotating.
