摘要： A blade-type tensioner for chain drives which is suitable for use as a tensioner on the timing chain of a motor vehicle engine. The present invention is a chain tensioner particularly suited for use in confined spaces having a blade spring element mechanically interlocked with a plastic shoe. The shoe may be of rigid filled nylon and engages the chain to be tensioned. The spring element is interlocked to the plastic shoe by having ends inserted into grooves formed in the opposite ends of the shoe. The shoe is rotatably fixed to a base by way of a pin. The groove at the fixed end of the shoe extends towards the tip of the fixed end of the shoe past the pin attachment point. The groove at the free end of the shoe extends toward the tip of the free end of the shoe past the point at which the free end of the shoe bears upon a sliding surface formed on the base.

摘要： A two speed shift mechanism for a belt drive that includes a rotatable shaft with a first pulley, and a tube concentric with the shaft and rotatable therearound. The tube includes a shift hub supporting a second pulley in axially spaced relation to the first pulley for concentric rotation about the shift hub. The mechanism further includes a collar mounted around the shift hub for rotation with the fit hub and for axial movement between a position adjacent the first pulley and a position adjacent the second pulley. In a first position, the collar and the first pulley include elements engageable for connecting the collar to the first pulley for rotation of the collar, the shift hub and the tube. In a second position, the collar and the second pulley include elements engageable for connecting the collar to the second pulley for rotation of the collar, the shift hub, and the tube.

摘要： A motorcycle has a final drive, including a flexible drive member, such as a chain or a belt, that extends between the drive pulley and the driven pulley. A belt retention member is positioned proximate a forward portion of the final drive to reduce the likelihood of the belt skipping free of the drive pulley. The belt retention member preferably includes an upper belt retention portion and a lower belt retention portion. Preferably, the upper drive retention portion is positioned further forward relative to the lower belt retention portion such that the upper portion is moved more forward relative to an axis of rotation of the pulley. In this manner, the belt retention member allows more slack to be thrown during rapid acceleration from a decelerated state in the illustrated motorcycle.

摘要： Means are provided for effectively restricting or preventing occurrence of abnormal noise under cold ambient. The means are durable, cost effective and also keep the function of a pulley. A ball bearing 2 of a single row type includes an outer ring 2a and balls 2c. The outer ring 2a and each ball 2c are contacted with each other at two points. An oil groove 5 is formed at a position adjacent to the contact positions P and Q on the raceway surface between the raceway surface 3a of the outer ring and the balls 2c. The ball bearing 2 is fitted within or made integral with the inner diameter of a pulley body 1 having a peripheral surface 1e to be contacted with a belt.

摘要： The present invention is directed to a roller chain and sprocket drive which has at least two sprockets with varied radial seating positions. The relative orientation of the sprockets are adjusted to provide favorable dynamics to the drive. This can include the minimization of the strand variation and providing the maximum strand variation for each chain strand to be phased differently than other strands.
