| 20110278133 | GAPLESS MAIN SHAFT LOCKING APPARATUS - A gapless main shaft locking apparatus includes a fastening ring, an elastic retaining device, a plurality of detent pins, a driving plate and an output shaft. The elastic retaining device is installed in the fastening ring and has an inner space in which elastic portions and cylinder portions are disposed. Each of the detent pins is disposed between one of the elastic portions and one of the cylinder portions. The driving plate has a central hole, and the periphery of the central hole includes fan-shaped convex portions. A side of the driving plate has a plurality of concave slots for receiving the elastic retaining device. The output shaft includes a polygonal shaft having a regular polygonal cross section. The polygonal shaft passes through the central hole of the driving plate, and each side of the polygonal shaft is contacted with one of the detent pins. | 11-17-2011 |
| 20150369319 | TORQUE LIMITATION SYSTEMS AND METHODS - A torque limited drive system comprising: an input shaft; at least one gear unit driven by the input shaft; a torque limiter having a torque limit and being driven by the at least one gear unit; and a torque limited output shaft driven by the torque limiter; wherein the torque limiter is adapted such that when it experiences a torque above its torque limit it applies a brake to said input shaft. The fact that the torque limiter is situated downstream of the gear units combined with the fact that the torque limiter brakes the input shaft upstream of the gear unit allows minimization of component weight within the gear units and within equipment driven by the output shaft due to the removal of the effect of efficiency and drag bandwidths associated with the gear units. | 12-24-2015 |

| 20090000902 | Window Winder Drive - A window winder drive functions with a freewheeling coupling, which has an outer coupling part and an inner coupling part, which is concentric thereto, and comprises clamping bodies arranged between a clamping face of the outer coupling part and a clamping face of the inner coupling part, wherein the clamping bodies are arranged in pairs in the annular space formed between the clamping faces, and the first clamping body of a pair of clamping bodies demonstrates a clamping effect exclusively in a specific direction of rotation of the outer coupling part in relation to the inner coupling part, while the second clamping body of the pair of clamping bodies exclusively has a clamping effect in the opposite direction of rotation. | 01-01-2009 |
| 20090250308 | Torque Limiter with Brake - A torque limiter device comprises a drive input, an output rotatable upon rotation of the drive input, and a roller-jammer device operable in the event that the torque transmitted between the drive input and the output exceeds a predetermined level to apply a braking load to the drive input and/or the output, and a brake device operable to apply a braking load to the roller-jammer device to cause activation thereof. | 10-08-2009 |
| 20100018832 | CLUTCH DEVICE FOR A SEAT LIFTING APPARATUS OF A VEHICLE - A clutch device for a seat lifting apparatus of a vehicle includes a friction brake portion for transmitting rotation of an operational lever to an output shaft, an output gear provided at the output shaft, a biasing force receiving portion provided at the output shaft for receiving a biasing force which assists a rotation of the output shaft, a first bearing portion provided at one side of the biasing force receiving portion and the output gear and a second bearing portion provided at the other side of the biasing force receiving portion and the output gear. The first bearing portion and the second bearing portion rotatably support the output shaft at both sides of the biasing force receiving portion and the output gear. | 01-28-2010 |
| 20110079486 | TRANSMISSION MECHANISM HAVING DECELERATION FUNCTION - A transmission mechanism having deceleration function includes a guide screw, a worm wheel set, an intermediary ring, an isolator and a passive sleeve. The worm wheel set is fitted onto the guide screw and includes worm wheel and plural claw arms. A spacing slot is formed between any two adjacent claw arms. The intermediary ring is fitted onto a peripheral edge of each claw arm. The isolator surrounds a peripheral edge of the intermediary ring with one side fixed to an actuator. With plural grooves arranged on a peripheral edge thereof, the passive sleeve is fitted onto the guide screw. An accommodation space is formed among the groove, spacing slot and intermediary ring. Each needle roller is accommodated in the accommodation space and inter-contacted with the claw arm, the intermediary ring and the passive sleeve. By frictional function, a rotation of the guide screw in a specific direction is hindered to reach a deceleration purpose. | 04-07-2011 |
| 20130313067 | INTEGRATED TORQUE LIMITER/NO-BACK DEVICE - An integrated torque limiter/no-back device for use in an actuator with an input shaft, an output and gear reduction. The device includes an input ramp to receive torque from the input shaft; a combined ramp to transfer torque; an output ramp to transfer torque to the gear reduction; one or more balls between the input ramp and the combined ramp and between the combined ramp and the output ramp to transfer torque; and a brake for causing torque to be grounded and for preventing backdriving of the input shaft by preventing movement of one or more of the input ramp, the combined ramp and the output ramp when a torque threshold has been met. The input ramp and the output ramp are a no-back ramp and a torque limiter ramp, respectively, and the device also includes a pin between the combined ramp and one or more of the no-back ramp and the gear reduction for transferring torque. | 11-28-2013 |
| 192223400 | Wrap-spring brake | 3 |
| 20090014272 | DRIVING FORCE INTERRUPTING MECHANISM - A driving force interrupting mechanism includes input and output members. A coupling sleeve is to be movable on the input and output members along a rotational axis. A fork is swingable around a swing shaft to move the coupling sleeve between a connecting position and a disconnecting position. The coupling sleeve is positioned on both of the input and output members in the connecting position. The coupling sleeve is positioned on either the input member or the output member in the disconnecting position. An operating member is integrally rotatable with the swing shaft. A spring is provided on the swing shaft between the operating member and the fork relatively rotatably with respect to the swing shaft. A motion of one of the operating member and the fork follows a motion of another of the operating member and the fork via an elastic force of the spring. | 01-15-2009 |
