Alternating Rotary Patents (Class 74/319)
  • Patent number: 8418585
    Abstract: The clutch control reversible transmission wheel system with bidirectional input and one-way output relates to a transmission structure, wherein the drive rotary direction of the input shaft of the wheel system with bidirectional input and one-way output is changed to make the direction of the output of the output shaft to be constant, which is characterized by releasing the connectable or releasable clutch device installed between transmissions of the wheel system with bidirectional input and one-way output, the output shaft is moved reversely when reversely driven.

  • Publication number: 20110041635
    Abstract: A transmission includes a body, a transferring gear set, a driving gear set, a reversible gear set, a unidirectional gear set, a wedge and a switcher. The body is mounted on a wheel. The transferring gear set includes a driving shaft and a transferring gear. The driving gear set includes a wheel hub and a driving gear. The reversible gear set includes a reversible sleeve and a reversible gear. The unidirectional gear set includes a follower gear, a unidirectional clutch and a unidirectional sleeve. The unidirectional clutch engages the reversible sleeve to the follower gear when the reversible sleeve is rotated in a first direction and disengages the reversible sleeve from the follower gear when the reversible sleeve is rotated in a second direction. The switcher moves the wedge to engage the recesses of the unidirectional sleeve and the reversible sleeve.

  • Patent number: 7752933
    Abstract: An actuator including a motor, clutch, gear train, solenoid, clock spring, and air brake is provided. The motor is configured to drive a control valve. The clutch is operably coupled to the motor and configured to prevent the motor from transferring more than a predetermined amount of torque. The gear train is operably coupled to the clutch and configured to receive the predetermined amount of torque from the motor. The solenoid is operably coupled to the gear train and configured to disengage one of the gears in the gear train from adjacent gears. The clock spring is operably coupled to another of the gears in the gear train, configured to store mechanical energy supplied by the motor, and configured to drive the control valve. The air brake is operably coupled to the gear train and configured to dissipate a portion of the mechanical energy released by the clock spring.

  • Patent number: 6568292
    Abstract: A method and a device are provided for achieving a step-by-step feeding, based on a rotary shaft which optionally can be made to execute one or more well-defined, whole rotation turns. The step-by-step feeding is achieved by mechanical connection between a driver joined to an output shaft and the inner periphery of a drive drum directly driven by a drive motor and arranged concentrically relative to both the driving and the driven shaft. The system is based upon the driver being adjustable between a first driving position and a second locked position.

  • Patent number: 4852594
    Abstract: A contact lens washing apparatus includes a body, a container mounted detachably on the body for receiving a washing liquid therein, and a porous basket mounted rotatably in the container for retaining a contact lens therein. A small motor in the body has a shaft which is connected to a speed reduction transmission. A rotational direction change mechanism interconnects with the speed reduction transmission and the basket for changing the unidirectional rotation output of the speed reduction transmission into the rotational reciprocating motion of the basket. That is, the basket will reciprocate alternately clockwise and counterclockwise to rinse the contact lens.

  • Patent number: 4776360
    Abstract: An automatic contact lens cleaner, generally shaped in an inverted U, comprises a battery holder, an electric motor, a speed reduction gear, an intermittent reversing gear using levers which engage a boss on the drive gear, and a pair of contact lens holders suspended from the reversing gear into a dish containing cleaning fluid. The bottom of the dish (one end of the U) is level with the bottom of the motor/battery-holder housing (the other end of the U), allowing the cleaner to rest upon any convenient supporting surface.

  • Patent number: 4653338
    Abstract: The preferred embodiment can be incorporated into a powered instrument which rotates a tool. The preferred embodiment permits changing the direction of rotation of the tool without using the hand that does not grip the instrument housing to operate the tool, and without altering the grip on the instrument. The preferred embodiment includes an actuator which moves between two positions to selectively couple two rotating members to an output shaft. The output shaft is rotated in one direction when one rotating member is coupled to the shaft and is rotated in the remaining direction when the remaining rotating member is coupled to the shaft. Movement of the actuator between its two operative positions can be achieved by pushing on the instrument housing to push the tool against the workpiece, or by pulling the instrument housing away from the chuck if the tool is embedded within the workpiece.

  • Patent number: 4344337
    Abstract: A reduction and reversing gear for marine propulsion systems making use of the clutch case of a conventional reduction and reversing gear of a type having an input shaft mounted on an upper part of the clutch case, an output shaft extending in parallel with the input shaft and mounted on a lower part of the clutch case, a multiple disc clutch carried by the input shaft, a small gear rotatably carried by the input shaft and adapted to be connected to and disconnected from the latter by the multiple disc clutch, and a large gear carried by the output shaft and engaging the small gear. A planetary gear type reduction gear is disposed in the space around the output shaft and below the multiple disc clutch to make an efficient use of that space, thereby to provide an additional reduction stage between the large gear and the output shaft.
