The input arm and an output arm each have a head portion for connecting with the central element and a body portion.

Abstract: A tolerance ring is arranged between an output-side rotary shaft and a rotor shaft. For this reason, even when looseness in a spline fitting portion of the output-side rotary shaft and rotor shaft is not filled, both the output-side rotary shaft and the rotor shaft are held by the tolerance ring so as not to rattle. Therefore, it is possible to reduce tooth hammer noise that occurs in the spline fitting portion. An output-side rotary shaft has oil passages for supplying lubricating oil to a tolerance ring. Lubricating oil is forcibly supplied through these oil passages to an annular space in which a tolerance ring is accommodated.

Abstract: The invention relates to a coupling for coupling two rotatable bodies, in particular a gear and a drive shaft, which are disposed essentially concentric to each other, with or without axial offset, having a coupling part. In order to reduce the structural height of the coupling, the coupling part is integrated into one of the rotatable bodies. In a fuel-supply pump, the drive shaft is coupled to the driven gear by means of the coupling part.

Abstract: A coupler is provided which responds to relative rotation of a driving and a driven shaft with variable rates of stiffness. As the two shafts experience slight degrees of relative rotation, such as at idle speed, the elastically deformable member of the coupler responds in a relatively soft manner with a slight degree of stiffness. As relative rotation increases because of the transmission of higher torque between the driving and driven shafts, the elastically deformable member responds with a stiffer reaction. The elastically deformable member also reacts in a similar manner with differing rates of stiffness to misalignment of the driving and driven shafts.

The drive ring transfers torque to the drive plate so as to absorb torsional vibrations which occur during operation of the system, so as to resist abrasion of the drive ring from the drive plate, and so as to resist failure from rotational shock loads imposed on the drive ring by the drive plate.

Abstract: A universal joint for use in an automobile tilt wheel assembly includes a first (12) and second (28) shaft. The end of the first shaft (12) includes a pin (20) extending on opposite sides of the first shaft (12). A pair of caps (22) having a circular outer periphery are rotatably disposed on the pin (20). Two socket member halves (34) interconnect the first shaft (12) and the second shaft (28). The socket members (34) define a circular pocket (36) for receiving the first end of the first shaft (12). The socket members (34) mate in a plane containing the axis of the pin (20). The socket members (34) define an outwardly flared recess (40, 41) to accommodate the sides (17) of the first shaft (12) during rotational movement of the cap members (22) in the circular pocket (36) and to accommodate movement of the first shaft (12) about the axis of the pin ( 20).

Abstract: Both the rotating drive and also the back and forth movement of the pump piston (5) occurs through a joint arrangement (29), which consists of a first through (65) on the crank (28), a second trough (67) on the piston (5) and a rolling member (30) which is received in the troughs (65, 67). The troughs are pressed by a springy ring (68) against the rolling member (30). The troughs (65, 67) have a slightly smaller curvature than the rolling member (30), so that the rolling member (30) rolls in the troughs (65, 67). Friction in the joint arrangement (29) is avoided through this, which results in a long life of the joint arrangement (29).

Abstract: A coupling shaft couples driving and driven shafts which are subject to relative misalignment. The coupling shaft has crowned male polygonal profiles on both of its ends, and which ends mate directly with corresponding female polygonal profiles carried by the driving and driven shafts. The crowned male profiles permit the coupling arrangement to act in a hinge like manner to accommodate the misalignment. Non-metallic bushings and adapters may be interposed between the coupling shaft and the driving and driven shafts to eliminate metal to metal contact and to thereby eliminate fretting and metal wear which would otherwise occur.

Abstract: A shaft coupling system for accommodating axial displacement and angular misalignment between two shafts. A hollow bushing is force fit into the hollow end of a first shaft. The bushing is provided with a plurality of part-circular recesses on its inner surface. A spline adapter is slip-fit onto a second shaft. The spline adapter cooperates with the bushing, and has spline teeth extending from its outer surface which are substantially boat-shaped. The shape of the teeth allows for extra clearance at the ends of the coupling system, which is necessary to accommodate angular misalignment. The bushing is made of readily replaceable and relatively inexpensive plastic materials.

The cylindrical and flat laminated elastomeric bearing means comprise alternating layers of an elastomeric resilient material and a nonextensible material to provide a more reliable coupling with improved performance.

The damper includes a plate (14) rigidly mounted to the quill shaft (6) and a plate (16) compliantly mounted to the rotor shaft (2) so that the rotor shaft plate (16) follows the angular displacement of the quill shaft plate (14) due to shaft misalignment which may occur, while torsional damping is achieved.

Abstract: A long wearing shaft coupling is comprised of metallic male and female members, and a plastic insert. The plastic insert is interference fitted into the female member, and the male member is slip fitted into the insert. The male member is provided with a number of part-circular shaped in transverse cross-section, radially outwardly extending projections which correspond to an equal number of similarly shaped and situated recesses in the insert. The plastic insert transmits the load between the male member and the female member, and is readily replaceable. The projections can be of a slightly smaller radius than the recesses, to allow for misalignments in the shaft. The slip fit nature allows for easy disassembling of the coupling.
