摘要： A power take off includes a housing, an input mechanism that is supported in the housing and is adapted to be rotatably driven by a source of rotational energy, and an output mechanism that is supported in the housing and is rotatably driven by the input mechanism, the output mechanism being adapted to rotatably drive a rotatably driven accessory. The power take off further includes a two piece damping assembly that minimizes the transmission of torque transients from the input mechanism to the output mechanism. The two piece damping assembly may be an input cluster gear assembly that includes a first gear portion and a second gear portion that are supported for rotational movement relative to one another. The two piece damping assembly may also be part of a clutch assembly for selectively the output mechanism to be rotatably driven by the input mechanism.

A second flange including an outer edge section, a first surface section, a second surface section opposite the first surface section, and a second plurality of passages. A connecting element extends between and connecting the first flange and the second flange through one of the first plurality of passages and one of the second plurality passages. The connecting element includes a connecting member having a first stop element and a second stop element. A compliant component is arranged on the connecting element. The compliant component is positioned on the connecting member between one of: the first stop element and the first surface; the second stop element and the second surface section; and between the second surface and the first surface section.

摘要： A driver for coupling a driving device and a driven device includes a core defining a plurality of corner chamfers and a casing formed on and encasing the core. The casing has a contoured perimeter surface and a variable casing thickness, and is compressible during an interference fit installation to a coupling socket to provide a non-lubricated coupling which has zero backlash and substantially no running noise. The core is made of a metal-based material and includes a shaft bore for receiving an input shaft. In an illustrative example, the driver core is made of a stainless steel core and the casing is made of a high wear thermoset urethane material. The metal core can be recycled from the coated driver by removal of the polymeric casing, then recoated with a new casing to form a new coated driver including the recycled metal core.

摘要： A rotation transmitting mechanism may include first and second tubular holders connected to first and second tubular members, respectively, to be incapable of rotating relative thereto, and a third tubular holder provided to project from an inside of the second tubular holder to the first tubular holder side and connected to the second tubular holder to be incapable of rotating relative thereto. The rotation transmitting mechanism may also include an inner coil spring, the ends of which are inserted inside of and respectively fixed to the first and third tubular holders, and an outer coil spring, the ends of which are inserted outside of and respectively fixed to the first and third tubular holders. The coils may have the same winding direction. In certain states, the second and third tubular holders may be connected to be incapable of rotating relative to each other.

摘要： A device for damping torsional oscillations, including: a pendulum-type torsional oscillation damper, a supplementary torsional oscillation damper including an input element, an output element, wherein both are configured to rotate around one axis rotation, and at least one mechanical energy accumulator device disposed between the input and output elements, a torque limiter, including at least one friction coating fixed on a disk, configured to be displaced around the axis. The disk is connected to rotate with the input element of the supplementary torsional oscillation damper and the friction coating is fixed to the disk of the torque limiter by an adhesively bonded surface-to-surface joint.

摘要： A damper device is provided with a first rotating body, a second rotating body, a coil spring and a spring seat. The coil spring is interposed in a circumferential direction between the first and second rotating bodies. The resin spring seat includes a seat portion, an overhang portion and a pair of clamping protrusions. The overhang portion extends in the circumferential direction from an outer diameter end of the seat portion and covers an outer diameter side of the coil spring. The clamping protrusions protrude from the seat portion and sandwich an attaching portion of the one of the rotating bodies. The clamping protrusions are relatively turnable in a radial direction of the rotating bodies. The clamping protrusions have a low-rigidity portion on an outer diameter direction side of the spring central axis and a high-rigidity portion on an inner diameter direction side of the spring central axis.

摘要： A torsional spring that can be used as a joint adapted to transmit a torsion actuation with elastic response. The torsional spring relates to a compact torsional elastic element, provided with a linear torque characteristic which is also not affected by the direction of rotation. The torsional spring is capable of attaining a high transmissible torque relative to its weight and overall dimension.

摘要： An isolator for isolating a device driven by an engine via an endless drive member is described. The isolator comprises a shaft adapter that is connectable with a shaft of the device, defining a shaft adapter axis, a rotary drive member that is rotatable relative to the shaft adapter and has an endless drive member engagement surface that is engageable with the endless drive member, and an isolation spring arrangement positioned to transfer torque between the shaft adapter and the rotary drive member. The isolation spring arrangement has at least one isolation spring that is axially offset from the endless drive member engagement surface. The at least one isolation spring has an outer edge that is radially outside the endless drive member engagement surface.
