摘要： A tensioner for tensioning a strand of chain between two sprockets including a tensioner body and a ramp fixed to ground. The tensioner body has an oval shape defined by first and second arcuately curved sides. Each side has a distal end, a proximal end, and a blade spring. The first and second arcuately curved sides are coupled together at the distal ends and pivotally attached to ground at the proximal ends. When the first arcuately curved side is in contact with the ramp, the second arcuately curved side is in contact with the chain strand, and the tensioner body is positioned relative to the ramp such that the blade springs of the tensioner body are compressed, a tensioning force is applied to the strand of chain.

摘要： The chain tensioner includes a tensioner arm with a blade spring and a wedge-shaped piston. Complementary friction surfaces of a pair of pawls push against the wedge-shaped piston to dampen the motion of the blade tensioner and hence tension the chain. The pawls are urged together and against the piston by spring loading. The combination of a blade tensioner and a wedging feature provides better chain control than a blade tensioner alone. The system requires no hydraulic fluid pressure from the engine.

摘要： A method of manufacturing a tensioner (10) by mounting an end member (38) on an end of a hollow tensioner shaft (24) includes a step of providing an end member (38) of sheet material with an opening (76) having a plurality of annularly spaced inwardly extending pointed projections (78). A hollow shaft (24) has an outwardly extending shoulder (82) at an end portion thereof. A relative axial movement between the end member (38) and the hollow shaft (24) is effected so that the end member (38) abuts against the shoulder (82) of the hollow shaft (24). The hollow shaft (24) is deformed at the end portion radially outward to embed the projections (78) into the hollow shaft (24) to thereby form a joint (32) therebetween.

摘要： A blade tensioner is configured with blade shoe having chain sliding face, base that supports base part of blade shoe while allowing it to pivot freely, and blade spring in which base part is fixed to tip part of blade shoe. Warped part provided at the tip contacts inner face of blade shoe, and curved part provided at the midpoint of base contacts sliding face of base. In this case, the damping force of the blade tensioner increases due to sliding resistance generated between warped part of blade spring and inner face and between curved part and sliding face.

摘要： The invention comprises a frictional damping strut. The strut comprises an inner cylinder that slides within an outer casing. A spring biases the inner cylinder away from the outer casing in an axial direction. A first wedge member cooperatively engages a second wedge member. The first wedge member having a frictional engagement with the inner cylinder such that when the inner cylinder is pressed into the outer casing the first wedge member bears upon the second wedge member causing the first wedge member to radially expand, thereby increasing a frictional force between the first wedge member and the inner cylinder. A second spring preloads the first wedge member against the second wedge member. A belt tensioner may incorporate the damping strut to preload a belt and damp belt oscillations.

摘要： An automotive tension device features a pair of pulleys which are pivotally mounted on the same pivot arm. The pulleys are positioned within the drive system (e.g., a belt drive system) in such a manner that the moments relative to the pivot axis created by the force resultant of the driving member passing around each of the pulleys are oppositely directed. Thus, the pulleys provide rotational support for each other. The tension device and arrangement is positioned within a belt drive system having a combination starter/generator, wherein the crankshaft ordinarily drives the belt but the starter/generator drives the belt on engine startup (an arrangement which creates varying kinematic conditions within the belt). One of the pulleys bears against a first, crankshaft-driving portion of the driving member extending from the crankshaft pulley to the starter/generator pulley on the driving side of the crankshaft, and the other pulley bears against a second, starter/generator driving portion of the driving member extending from the starter/generator pulley to the crankshaft pulley on the driving side of the starter/generator pulley.

摘要： The invention comprises a self-contained mechanical belt tensioner that produces damping which is a function of the applied hubload through the effect of frictional forces derived from the sliding action of mutually opposing wedges. A first wedge or conical piston is contained within a housing. The conical piston cooperates with a second or conical wedge. A surface of the conical wedge slides on the inner surface of the housing. The conical wedge is expandable in a direction normal to the inner surface of the housing. A spring urges the conical wedge into engagement with the conical piston. As the pulley is loaded, as with an impulse load, the piston will move into the conical wedge. This, in turn, will cause the conical wedge to expand against the inner surface of the housing. The expansion of the conical wedge in the housing will increase the frictional force between the conical wedge and the housing. This will have the effect of damping movements of the conical piston and, in turn, of the pulley. The greater the impulse, then the greater the expansion of the conical wedge. This increases the resultant frictional force resisting movement between the conical wedge and the housing. As the load moves toward a minimum, the frictional force is abated to a low level allowing ease of retraction of the piston.
