Abstract: The paper transferring mechanism includes a drive gear coaxially coupled with a rotation shaft of a motor, a pick-up gear coupled with a shaft of a pick-up roller to separately feed the paper sheets, and a feed gear coupled with a shaft of a feed roller to outwardly transfer the paper sheets. The paper transferring mechanism also includes a discharge gear coupled with a shaft of a discharge roller to outwardly discharge the paper sheets, and a swing gear having one end connected to the drive gear and the other end selectively connected to one of the pick-up gear and the feed gear. The pick-up gear is rotated when the motor is rotated in a first direction, the feed gear is rotated when the motor is rotated in a second direction, and the discharge gear is rotated constantly in one direction regardless of the rotation direction of the motor.

Abstract: A power transmission device includes a pair of gear assemblies and an idle. Each of the gear assemblies includes a first gear having continuous external teeth on a peripheral wall and a second gear having continuous external teeth on a peripheral wall. The first gear and second gear are arranged to form a one-way clutch. When the first gear rotates in one direction relative to the second gear, the first gear is not connected to the second gear. When the first gear rotates in the other direction relative to the second gear, the first gear is connected to the second gear. The external teeth of the first gears in the gear assemblies engage each other, and the external teeth of the second gears in the gear assemblies engage the idle gear. One direction output at the second gear is obtained regardless of an input direction at the first gear.

Abstract: A dual drive system for a hydraulic pump and an air boost compressor is provided. Reversible power is transmitted to a shaft connected to clockwise and counterclockwise over-running clutches connected to different vehicle or equipment subsystems. Reversing the drive allows power to be alternately transmitted to one or the other of the subsystems. The invention includes utilizing the dual drive for hydraulic and air conditioning systems for an aircraft, with the provision of an additional drive motor providing constant power to one or more of the subsystems.

Abstract: The invention relates to a transmission assembly comprising at least one input shaft (1) driven in rotation and in engagement with a toothed wheel (2A).

Abstract: Transmission mechanism of drilling/milling tool, including a motor capable of forward and backward rotating. The motor has a transmission shaft for transmitting the power to the transmission mechanism. The transmission mechanism further includes a movable slide gear, a first and a second driven wheels constantly engaged with the slide gear and a brake or shaft mounted on a driving wheel or the driven wheel. The slide gear is responsive to the forward and backward rotation of the transmission shaft to axially move along the brake or shaft to selectively drivingly engage with the first or second driven wheel. In the forward and backward travel of the drill bit or blade, the drill bit or blade is rotated at high or low rotational speed.

Abstract: The present invention provides a compact transmission assembly for use in a coin storage and dispensing apparatus. The transmission assembly can connect the rotational output of a reversible electrical motor to a link unit that supports a switching gear unit. A helical gear unit can be mounted adjacent to the link unit and can be driven axially along a shaft to contact a mounting unit to receive a thrust force and to drive the link unit in a clockwise or counter-clockwise direction depending upon the rotation of the reversible motor. The switching gear unit is radially mounted at an offset position on the link unit and can appropriately contact output gears connected to output shafts for providing a selective dual power output.

Abstract: A structure of a variable transmission device includes an input shaft driven by a motor to perform alternate rotation having a gear on a middle portion, an output shaft having a pair of gears secured to the upper and lower ends respectively and a speed changing shaft positioned between the input and output shaft having a pair of gears rotatably secured to two ends respectively meshed with the gears of the output shaft and a spiral outer periphery on a middle portion rotatably and slidably engaged with an inner threaded gear which meshes with the teeth of the gear of the input shaft. Thereby, the rotation of the input shaft drives the inner threaded gear to rotatably slide about the spiral outer periphery to force the gears of the speed changing shaft to rotate and in turn to drive the gears of the output shaft to rotate in concert with the input shaft.

Abstract: A device (1), particularly a facsimile apparatus, has a reversible motor (26), an intermediate transmission gear (29) which is drivable by the motor (26), and three drive wheels (44, 48, 51) which are drivable with the aid of the intermediate transmission gear (29). The intermediate transmission gear (29) includes a basic member (30) which is drivable by the motor (26), a control member (36), and a drive member (37). A first unidirectional coupling of the basic member (30) and the control member (36), and a second unidirectional coupling of the basic member (30) and the drive member (37) are constructed to transmit power in opposite directions of rotation (31, 32). The control member (36) is adapted to selectively establish a drive transmission between the motor (26) and at least one drive wheel (44, 48, 51), and the drive member (37) is adapted to drive the drive wheels (44, 48, 51).

The transmission agent includes a first and second toothed wheel mounted on an incoming shaft, which is arranged to be driven by the motor, a third toothed wheel and a fifth toothed wheel are arranged on the shaft for the holder, freewheel hubs are arranged at the shaft for the holder between the third and the fifth toothed wheel. The freewheel hubs are capable of locking a toothed wheel in one direction of rotation. Due to the arrangement of the toothed wheels, a first and second drive path is formed so that the transmission agent is capable of achieving two gear changes on an outgoing shaft, depending on the direction of rotation of the motor.

Abstract: A gearbox arrangement couples an input shaft to an output shaft whereby the output shaft is driven by the input shaft in a constant rotational direction but at two different rotational speeds depending upon the particular direction of rotation of an input shaft for a given rotational speed of the input shaft. The input shaft has an input gear integral therewith and the output shaft has an output gear integral therewith. A first unidirectional clutch couples the input shaft with the output shaft such that rotation of the input shaft in a first input direction at a first input speed rotates the output shaft in a first output direction at a first output speed, but rotation of the input shaft in a second, opposite input direction causes the first unidirectional clutch to slip. An idler gear meshes with and is driven by the input gear. An intermediate shaft has a first intermediate gear integral therewith. The first intermediate gear is meshed with and driven by the idler gear.
