| 20090093329 | CHAIN NOISE REDUCTION DEVICE - A cushion ring ( | 04-09-2009 |
| 20110300977 | SPROCKET - In a sprocket comprising a sprocket hub, sprocket teeth and a cushion plate for contacting link plates of a transmission chain, the cushion plate is formed with concave portions at angular positions corresponding to the angular positions of the tips of the sprocket teeth, thereby avoiding contact, or reducing contact pressure, between the cushion plate and the middle parts of link plates of the chain. | 12-08-2011 |
| 20080312018 | Power transmission and hub used for power transmission - In a power transmission | 12-18-2008 |
| 20090264234 | Electric rotary machine - An AC generator for vehicles as an electric rotary machine, a pulley is fixed to a rotating shaft, and a belt transmits a driving force from outside to the rotating shaft via the pulley. The pulley comprises a cylindrical portion in contact with the belt, an attachment part screwed and fixed to the rotating shaft by fitting, a supporting part which joins the attachment part and the cylindrical portion, and a reinforcement part having its form projected to an inner diameter side of the cylindrical portion that is located in the opposite side of the supporting part to the direction against the center position of an axis of the belt | 10-22-2009 |
| 20100304907 | Torsional Compensator - A torsional compensator having an inner hub, an outer sprocket, left and right grippers, and a resilient torsion sleeve. The torsion sleeve occupies a generally annular cavity between the inner hub and outer sprocket and each end of the sleeve is coupled to a gripper. One gripper is coupled to the inside of the outer sprocket and the other gripper is coupled to the outside of the inner hub and they are axially spaced apart. The inner hub supports the outer sprocket for coaxial rotation thereon. | 12-02-2010 |
| 20090118047 | RANDOM ELASTOMER CUSHION RINGS FOR A CHAIN SPROCKET - A sprocket includes a plurality of teeth spaced about its periphery, roots located between pairs of adjacent teeth, and a cushion ring contacted by a chain engaging the sprocket teeth. The roots have root radii defined as the distance between the center of sprocket and the point along the root closest to the sprocket center in the radial direction. In some embodiments, the roots have three distinct radii. The cushioning material of the cushion ring receives the impact while engaging the chain. In some embodiments, the cushion ring has a contour substantially following the contours of the sprocket teeth geometry. In some embodiments, the cushion ring has a randomized contour to provide predetermined cushioning that varies from tooth to tooth around the sprocket. | 05-07-2009 |
