  • Publication number: 20150135874
    Abstract: Provided is a clutch device capable of reliably transmitting predetermined torque. Power is transmitted from an outer ring to a second gear through a first gear. The teeth of the first gear are formed so that the lines of the teeth are non-parallel to the center axis. The direction of axial force generated by the reaction force of the second gear and acting on the first gear is set to be the same as the direction of movement of the outer ring. When rollers engage with raceway surfaces and power is transmitted from the first gear to the second gear, the reaction force of the second gear promotes the movement of the outer ring in the axial direction. Predetermined torque can be reliably transmitted because axial pull-in force between an inner ring and the outer ring increases.

The drive shaft contains keyed structures and, depending on its position within the gear system, the keyed structures on the drive shaft engage or disengage a plurality of key stops. The key stops, in turn, interact with the gears to generate the desired gear ratio. The contours of the keyed structures on the gear holder allow the drive shaft to move between positions without first being specifically positioned. The gear-driver adapter also includes a handle adapter and a driver adapter, allowing users to use any handle or driver with the gear-driver adapter.

    Abstract: A gear coupling device and a gear coupling method reduce a vibration and noise caused at the time of engagement of gears. The gear coupling device transmits power through the engagement of the gears and uncouples the gears from each other by causing at least one of the gears to move in an axial direction of the gear. A determining section determines, on the basis of signals detected by rotation sensors, whether or not an end surface of a tooth of the axially moving gear lies between an end surface of a first tooth of the other gear and an end surface of a second tooth of the other gear. A driving section causes the gear to move in the axial direction on the basis of the determination result of the determining section and causes the gears to be coupled to each other.

  • Patent number: 8631717
    Abstract: One aspect of the instant disclosure is to provide a sensorless adaptive safety actuator. The safety actuator comprises a driving unit, a transmission unit coupled to the driving unit, and an output unit coupled to the transmission unit. The transmission unit comprises a load-adaptable retracting mechanism. When the output unit experiences a mechanical load exceeding a critical value, the load-adaptable retracting mechanism causes the transmission unit to decouple from the driving unit. Thus, responding to an accident where the impact on the output unit causes a force/torque overload, the instant safety actuator is capable of effectively stopping the force/torque transmission to the work output device without the use of active sensors.

  • Publication number: 20140007723
    Abstract: In a drive force transmission apparatus, when an input shaft is rotated in a normal rotational direction, a rotational force of the input shaft is transmitted to an output shaft through a one-way clutch to rotate the output shaft at a rotational speed, which is the same as a rotational speed of the input shaft. At this time, an input side sub-shaft is freed from an output side sub-shaft. In contrast, when the input shaft is rotated in a reverse rotational direction, the rotational force of the input shaft is transmitted to the output shaft through an input gear, a first gear, the input side sub-shaft, a two-way clutch, the output side sub-shaft, a second gear and an output gear. At this time, the output shaft is freed from an intermediate shaft.

  • Patent number: 8615184
    Abstract: The present invention provides a driving component, and a photosensitive drum and a process cartridge comprising the driving component. The driving component comprises a gear fixed at one end of the photosensitive drum and a longitudinal regulating component. The longitudinal regulating component comprises a first motion subassembly, a groove part and a central shaft part. The groove part has an upper chute and a lower chute which are orthogonal in space. The first motion subassembly forms relative slide coordination with the upper chute along a first direction. The central shaft part has a common axis with the gear which forms relative slide coordination with the lower chute along a second direction. The first direction and the second direction are all perpendicular to the longitudinal direction of the photosensitive drum.

    Abstract: A damper system may include a handle mechanism for use with a damper actuator system. Illustratively, the handle mechanism may include a drive gear mechanism, a handle, a housing, and a spring, and may be actuated to set a crack pressure for the damper system. The handle may connect to the drive gear mechanism at a drive gear arm of the drive gear mechanism and may flip over or about the drive gear arm to move from a first position to a second position. In some instances, once the handle is in the second position, a force may be applied thereto to disengage the drive gear from a stop member and thereafter, the handle may be rotated to change the crack pressure of the damper system.

  • Publication number: 20130305861
    Abstract: Clutch arrangement for a motor vehicle gearbox. The clutch arrangement has a housing and a clutch. The clutch is arranged in the housing and is arranged concentrically with a shaft, which extends in a longitudinal axis. The shaft is supported on the housing by means of a first shaft bearing adjacent to the clutch and by means of a second shaft bearing spaced at an axial distance from the clutch. The clutch arrangement has an actuator arrangement for actuating the clutch. The actuator arrangement is designed to exert an actuating force on the clutch in a first longitudinal direction. The actuator arrangement here being axially braced on the housing and a force flux being introduced into the shaft as a result of the actuating force. The first shaft bearing is arranged so that the force flux introduced into the shaft can be axially braced on the housing by way of the first shaft bearing.
