摘要： A non-return device for coaxial rotation transmission includes coaxial input and output shafts, a frame for guiding the rotation of the shafts. A locking element is urged in radial translation through a channel of the output shaft between a radial locking position, in which the locking element projects from the channel so as to prevent a rotation of the output shaft by abutting against the frame, and a radial unlocking position, in which the locking element is retracted so as to allow axial rotation of the output shaft. The input shaft includes means for radially switching the locking element between the locking and unlocking positions thereof.

摘要： The electric motor with a reverse input cutoff clutch has an output shaft. The output shaft is configured by connecting a first shaft and a second shaft that are coaxially arranged with each other via the reverse input cutoff clutch. The second shaft is rotatably supported to a housing by one radial bearing. The reverse input cutoff clutch has a function that, when rotational torque is inputted to the first shaft, transmits the rotational torque inputted to the first shaft to the second shaft, and when rotational torque is reversely inputted to the second shaft, completely cuts off the rotational torque reversely inputted to the second shaft, and does not transmit the rotational torque to the first shaft, or transmits a part of the rotational torque to the first shaft, and cuts off the remaining part.

摘要： A reverse rotation prevention mechanism is provided on a torque transmission path between an output shaft and a driving shaft of a motor, and includes: a relative rotation inhibition unit configured to inhibit rotation of a lock plate provided on the torque transmission path from rotating relative to an output pin when an external force in a rotational direction is exerted on the output shaft; and a lock plate side brake member configured to generate a braking force that prevents reverse rotation when an external force in the rotational direction is exerted on the output shaft, by causing a portion of the lock plate to be pressed. The relative rotation inhibition unit is provided in an area different from the lock plate side brake member.

摘要： The REVERSING TRANSMISSION includes a shaft, a retainer, a spacing collar, a plurality of reversing members, two gears and two covers. The holder is sleeved on the shaft with spaced sliding notches formed thereon. The spacing collar is mounted on an outer surface of the retainer. The reversing members each includes two spaced swing plates with two reversed spiral teeth dented on two diagonal half surfaces of the two spaced swing plate. The reversing members slide into the sliding notches of the holder with two swing plates distributed at different side of the spacing collar. Each of the gears has a group of spiral teeth formed on the inner side for engaging with the group of spiral teeth of the reversing members, and cogs formed on the outer circumference surface. The covers are mounted on two opposite ends of the holder to keep the reversing member in position.

摘要： The present invention discloses and claims a torque transfer mechanism. The torque transfer mechanism connects an input shaft to an output shaft to transmit rotation and torque in either direction from the input shaft to the output shaft. The torque transfer mechanism also inhibits the transmission of rotation and torque in at least one direction from the output shaft to the input shaft. In alternate embodiments, the torque transfer mechanism may transmit rotation and torque in one direction from the output shaft to the input shaft. In still further embodiments, the torque transfer mechanism may inhibit the transmission of rotation and torque in either direction from the output shaft to the input shaft.

摘要： A reverse input blocking clutch comprises, as main elements, an input member, an output member, a stationary member for constraining the revolutions, locking means, lock release means and torque transmission means. By forming the input member, the output member, the stationary member and a fixed side plate from metal plates such as press worked steel plates, a compact, lightweight and low cost reverse input blocking clutch is provided. Reverse input torque from the output member is locked in both the forward and reverse rotational directions relative to the stationary member, by rollers which function as the locking means. Input torque from the input member in both the forward and reverse rotational directions is transmitted to the output member via apertures 1d and protrusions which function as the torque transmission means.
