摘要： A drive unit comprising a motor, a drive shaft and a coupling unit. The coupling unit comprising a bearing sleeve, an input hub, an output hub and a torsion spring. The bearing sleeve at least partially surrounding said drive shaft and said torsion spring surrounding said bearing sleeve. The input hub coupled to said drive shaft and being at least partially rotatably mounted on said bearing sleeve. The input hub is at least partially arranged between the two spring ends, wherein the output hub is at least partially rotatably mounted on the bearing sleeve. The input hub acts on the torsion spring upon a rotation caused by the input hub and thereby slides on the bearing sleeve, and that upon rotation caused by the output hub, the output hub acts on the torsion spring in such a way that the torsion spring interacts with the bearing sleeve and prevents rotation.

摘要： Described are, among other things, a steering coupling (50) for interconnecting a steering gear with a steering aid device is provided. The steering coupling comprises a first, outer, shaft (52) having a plurality of inward projecting teeth (53), and a second, inner, shaft (54) having a plurality of outward projecting teeth (55) in direct co-operation with the first outer shaft to form a steering coupling. The first shaft and the second shaft are configured to rotate together in both rotational directions around a common axle. The steering coupling also comprises at least one clastic pad (56), wherein the at least one clastic pad is provided in a pocket (58) of one of the shafts and where the at least one clastic pad abuts pocket side walls in both said rotational directions of the shaft in which the pocket is located. The at least one elastic pad also has a projection extending out from the pocket and wherein said projection abuts sides in both said rotational directions of the tooth/teeth of the shaft cooperating with the shaft provided with the pocket. Hereby the steering coupling can be assembled such that no, or a significantly reduced, play can be achieved in the steering coupling. The steering coupling can then be aided by a steering aid device such as an electrical motor without causing oscillation in the steering aid device and thereby improve power efficiency and reduce wear on the steering aid device. Also steering wheel vibrations can be eliminated, steering coupling and arrangement related thereto

摘要： A mechanical coupling is disclosed. The mechanical coupling includes a first coupling member and a second coupling member. The first and second coupling members each include a body having a first end and an opposed second end. The body defines a central axis. Each coupling member further includes at least one finger that extends from the body in the direction of the central axis and a recess that extends radially into the body, the recess extending between the first end and the second end of the body. The recess has a base that includes at least one channel. The coupling further includes a first resilient member received in the recess of the first coupling member and a second resilient member received in the recess of the second coupling member. The first and second resilient members each include at least one projection that is configured to be received by the channel of the recess of the respective first coupling member or of the second coupling member.

摘要： A damper device includes a first rotor, a second rotor, an elastic coupling part elastically coupling the first and second rotors in a rotational direction, and a hysteresis generating mechanism. The hysteresis generating mechanism generates a hysteresis torque and includes a friction member. The friction member is configured to make frictional contact with the first or second rotor. The friction member does not make frictional contact with the first and second rotors in a first torsion angular range where torsion is caused from a neutral condition to a first side and a second side in the rotational direction. The friction member makes frictional contact with the first or second rotor so as to generate a hysteresis torque in a second torsion angular range exceeding the first torsion angular range. The friction member is set in a neutral position by actuation of the elastic coupling part in the neutral condition.

摘要： The disclosure relates to a belt pulley decoupler for transmitting torque between the belt of a belt drive and a shaft in driving connection therewith. The belt pulley decoupler includes: a hub fastened to the shaft, a belt pulley rotably mounted on the hub, helical torsion spring arranged in a torque flow path between the belt pulley and the hub, a first spring plate extending in the torque flow path on a side of the belt pulley, and a second spring plate rotationally fixed to the hub.
The hub has an imbalance which compensates for an imbalance of the helical torsion spring resulting from a ground portion of the spring ends in such a way that the following relationship applies for the spring imbalance {right arrow over (U)}s and the hub imbalance {right arrow over (U)}b.

|{right arrow over (U)}s+{right arrow over (U)}b

摘要： A marine engine coupler for connecting a sterndrive input shaft to an engine flywheel. A splined central shaft connects the sterndrive input shaft to the coupling. Polyurethane dampers interface between the engine to the sterndrive to reduce vibration. There is a visual indicator on the coupler to allow the user to assess the integrity of the dampening material and give the user an indication that the dampening materials needs to be replaced.

摘要： A decoupler pulley is provided for automotive belt-driven accessory drives, which utilizes a single torsion coil spring that provides torsional resiliency and overrunning functionality. As the torsion spring expands it increasingly pinches a bushing disposed between a radially expansible hub and pulley to thereby provide proportional damping.
