摘要： A camshaft in an internal combustion engine encounters various torques during operation which produce torsional vibrations leading to excessive noise and reduced gear life. An active inertia absorbing system includes a camshaft gear integrally formed with a carrier. The carrier has a plurality of bores having a predetermined diameter. A plurality of weights are positioned within the bores and have a predetermined diameter less than the predetermined diameter of the bores so that the weights are free to move within the bores. The mass of the carrier and the weights establish an inertia which acts in opposition to the torques applied to the camshaft for absorbing the torsional vibrations of a camshaft.

摘要： A damped torsional coupling is utilized to couple a drive shaft to a work shaft while permitting some relative rotation due to torsional vibrations. The coupling includes a second coupler oriented to rotate with respect to a first coupler about an axis through a continuum of negative to positive torque orientations. The first coupler defines a fluted perimeter surface with a number of flutes, distributed with radial symmetry about the axis. The second coupler a number of pistons reciprocally received in respective barrels to define a variable volume chamber fluidly connected to a damping passage. A spring biases the pistons and barrels to extend toward a position in contact with one of the flutes. The contact end may be an edge of a roller that rolls on the fluted perimeter surface in one of the flutes responsive to torques transmitted between the couplers.

摘要： A compliant gear assembly for a gear train of an internal combustion engine includes a hub subassembly having a first hub component and a second hub component. The first hub component defines a first axis, and the compliant gear assembly includes a gear ring rotatable relative to the hub subassembly and defining a gear ring axis of rotation. The second hub component is movable relative to the first hub component in a direction normal to the first axis between a first stop position at which the gear ring axis of rotation is co-linear with the first axis and a second stop position at which the gear ring axis of rotation is parallel to but not co-linear with the first axis. A compliance mechanism is coupled between the first hub component and the second hub component and biases the second hub component toward the first stop position. Translating the second hub component relative to the first hub component in a direction normal to the first axis attenuates torque spikes induced for example via fuel injector actuation and/or cylinder firing in an engine gear train employing the compliant gear assembly.

The output member is configured to provide a torsional output. The transfer assembly is coupled between the input member and the output member and includes a ring, a first guide, a second guide, a first spring, and a second spring. The ring defines a first linear slide path that has a first end and a second end, and a second linear slide path that has a third end and a fourth end. The first guide is slideable within the first linear slide path and coupled to the input member. The second guide is slideable within the second linear slide path and coupled to the input member. The first spring is positioned between the first guide and the second end of the first linear slide path. The second spring is positioned between the second guide and the fourth end of the second linear slide path. Movement of the input member relative to the output member causes the first guide to slide along the first linear slide path and the second guide to slide along the second linear slide path.
