摘要： A pump system may include a pump, a driveshaft, driving equipment, and a vibration dampening assembly configured to reduce pump-imposed high frequency/low amplitude and low frequency/high amplitude torsional vibrations. The pump may have an input shaft connected to the driveshaft. The driving equipment may include an output shaft having an output flange connected to the driveshaft. The driving equipment may be configured to rotate the driveshaft to rotate the input shaft of the pump therewith. The vibration dampening assembly may include one or more flywheels operably connected to the input shaft and configured to rotate therewith.

摘要： A damped isolation pulley having a hub, a pulley disposed concentrically about the hub, an isolation spring, an inertia ring and an electro-adhesive clutch. The hub is configured to be mounted to a crankshaft of an internal combustion engine. The isolation spring is formed of an elastomeric material and couples the pulley to the hub. The inertia ring is resiliently coupled to the hub and is rotationally de-coupled from the pulley. The electro-adhesive clutch has a clutch input member that is coupled to the pulley and can be operated to form an alternate torque path between the pulley and the hub that does not include the isolation spring.

摘要： A rotary device includes a first rotor, a second rotor, a centrifugal element, and a first rolling member. The first rotor includes an accommodation portion having first and second guide surfaces. The first and second guide surfaces face both sides in a circumferential direction. The first rotor is disposed to be rotatable. The second rotor is disposed to be rotatable with and relative to the first rotor. The centrifugal element is disposed within the accommodation portion. The centrifugal element is disposed to be radially movable by a centrifugal force acting thereon in rotation of the first or second rotor. The centrifugal element rotates about a rotational axis thereof in radial movement thereof. The first rolling member is disposed between the first guide surface and the centrifugal element. The first rolling member rolls on the first guide surface in accordance with rotation of the centrifugal element about the rotational axis thereof.

摘要： A vibration isolator can be configured to provide improved vibration isolation performance, such as in connection with a bicycle saddle. A vibration isolator can be operatively connected to a bicycle saddle. The vibration isolator can be configured to exhibit a non-linear stiffness profile. The non-linear stiffness profile can include a region of quasi-zero stiffness. The vibration isolator can include one or more movable body members and one or more super elastic material members.

摘要： A torque limiter fixed to a flywheel including an annular portion and an accommodation portion is disclosed. The torque limiter includes a first plate, a second plate axially opposed to the first plate, a friction disc disposed between the first and second plates, a pressing member, and a third plate. A torque is inputted to the first plate. The pressing member presses the second plate onto the friction disc. The third plate supports the pressing member with the second plate therebetween while the pressing member is compressed. The third plate includes a support portion supporting the pressing member and a tubular portion provided in an outer peripheral part of the support portion. The tubular portion covers an outer peripheral surface of the friction disc. The tubular portion axially extends and is opposed to an inner peripheral surface of the annular portion of the flywheel, and includes first openings circumferentially aligned.

摘要： Damper apparatus for use with vehicle torque converters are disclosed. A disclosed damper assembly for a vehicle torque converter includes a first portion operatively coupled to a clutch of the vehicle torque converter and configured to receive an engine torque from the clutch based on a state of the clutch. The damper assembly also includes a second portion and a hub rotatably coupled to a turbine of the vehicle torque converter. The damper assembly also includes a gear train including a ring gear coupled to the first portion, a planet gear rotatably coupled to the second portion, and a sun gear coupled to the hub. The damper assembly also includes a primary damping element positioned in a cavity formed by the second portion. Rotation of the first portion relative to the second portion compresses and decompresses the primary damping element to dampen a torsional vibration associated with the engine torque.

摘要： A damper is disposed in at least one of a space between a supported member and a supporting element or a space between the supported member and a supporting member. The damper includes a cushioning member and a protecting member. The cushioning member is configured to relax stress applied to the supported member that is supported by the supporting member together with the supporting element. The cushioning member includes a facing portion that faces the supported member, an opposite portion that is opposite to the facing portion, and a side surface portion that is located between the facing portion and the opposite portion. The protecting member is disposed on the side surface portion to cover the cushioning member from an outside of the cushioning member.
