20080305904 | TRANSMISSION WHEEL FOR MOTOR VEHICLE ALTERNATOR - A cushion ring is provided between a transmission shaft and a transmission wheel's sleeve. The cushion ring has a number of centripetal teeth, thereby forming a number of chambers around the cushion ring. Inside each chamber, there is a slope section slanting towards an adjacent first tooth, and there is a spring element pressing a ball (or cylinder) against the slope section and the first tooth. The diameter of the ball or cylinder is such that it stands on the slope section to be slightly beyond the teeth and contacts an outside surface of the transmission shaft. As such, when the engine is ignited and a jitter causes the transmission shaft to turn in a reversed direction, the balls and cylinders are rolled towards the spring elements and the rotational force is thereby absorbed by the spring elements. | 12-11-2008 |
20140357439 | PULLEY RING - A structural or support ring for an overmolded pulley, the ring placed between a bearing and outer radial surface of the pulley, providing structural support across a width of the pulley. | 12-04-2014 |
20150141184 | BELT-DRIVEN STARTER-GENERATOR - A belt-driven starter-generator includes a rotary shaft, and a pulley belt coupled on an outer peripheral surface of the rotary shaft. A key is press-fitted into a pocket formed between the rotary shaft and the pulley belt so as to fix the rotary shaft to the pulley belt. A coupling member is coupled to a thread formed on the outer peripheral surface of the rotary shaft so as to support one side of the pulley belt. Operational reliability and assembly convenience may be improved by the belt-driven starter-generator of the present disclosure. | 05-21-2015 |
474169000 | Plural grooves of different circumferences | 1 |
20100190597 | Pulley for a Cableway System and Set of Pulleys for Producing a Belt Drive - A pulley for the production of a belt drive, in particular for driving deceleration wheels, conveying wheels and acceleration wheels in cableway systems, is formed in its central region with a hub for connecting it to a drive shaft and at its periphery with an annular belt surface, in particular a groove, for a drive belt or the like. The pulley consists of sheet steel and the belt surface provided on its periphery thereof is produced by splitting the rim of the pulley. | 07-29-2010 |
