摘要： The invention discloses a novel method for constructing a torsional vibration damper where the spring damper system is aligned axially with the axis of the device, and it is put into compression by axially reducing its width and simultaneously preventing radial expansion. The assembly of the torsional vibration damper occurs in two progressive controlled stages by torquing a set of fasteners, thereby minimizing the shear strain on the elastomer during assembly, enhancing structural robustness, modally stability, and serviceability in the field.

摘要： A filtering pulley assembly for an accessory drive of a vehicle has a hub fixedly attachable to a rotating shaft, a pulley mounted coaxial and freely rotating on said hub, an actuator disc carried by the hub, a plurality of elastic assemblies interposed between the pulley and the actuator disc, and a torque limiting coupling configured to rotationally connect the actuator disc to the hub, when the torque is below a predetermined threshold value, and to decouple the actuator disc from the hub, when the torque is above the threshold value.

摘要： Described is a generator for an engine-driven power system. The generator having a generator shaft, a sleeve coupler, a first pulley, and a second pulley. The generator shaft, which is shaped at an end to define a first tapered surface, rotates a rotor relative to a stator. The sleeve coupler is shaped to define a bore with a second tapered surface. The bore receives the end of the generator shaft. The first pulley has a center hole to receive the sleeve coupler. The second pulley shares an axis of rotation with the first pulley and transfers a rotational force to the generator shaft and to the sleeve coupler.
