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 (14) is contained within a housing (1). The conical piston cooperates with a second or conical wedge (13). The outer surface of the second conical wedge slides on the inner surface of the housing. The second conical wedge is expandable in a direction normal to the inner surface of the housing. A spring (6) urges the conical wedge into engagement with the conical piston. As the pulley (8) 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.

摘要: According to an embodiment of the invention, blade tensioner (1) is configured with blade shoe (2) having chain sliding face (20a), base (4) that supports base part (2a) of blade shoe (2) while allowing it to pivot freely, and blade spring (3) in which base part (3a) is fixed to tip part (2b) of blade shoe (2). Warped part (3b) provided at the tip contacts inner face (20b) of blade shoe (2), and curved part (3c) provided at the midpoint of base (4) contacts sliding face (4a) of base (4). In this case, the damping force of the blade tensioner increases due to sliding resistance generated between warped part (3b) of blade spring (3) and inner face (20b) and between curved part (3c) and sliding face (4a).

摘要: In pressing a slack-side span 16a of a V-ribbed belt 16, entrained about a crank pulley 1 variable in rotational speed, auxiliary pulleys 4, 7 and 10 and an idler pulley 13, with an auto tensioner 24, thereby automatically balancing tension of the belt, the damping coefficient DI of the auto tensioner 24 is set in accordance with the modulus of longitudinal elasticity of the belt 16. For example, when the modulus of longitudinal elasticity of the belt 16 is at least 9800 N/100% rib and less than 29400 N/100% rib, the damping coefficient DI of the auto tensioner 24 is set at at least 20% and less than 100%. In this manner, even if the rate at which the auto tensioner 24 absorbs elongation of the belt 16 is as extremely small as 0.3 to 1.0 mm/deg, a rocking motion of the auto tensioner 24 can be avoided thereby reducing the occurrence of a slip or a frictional sound of the belt 16 and the occurrence of abrasion and frictional sounds of friction members, such as an insert bearing 27 and a thrust washer 33, of the auto tensioner 24.

摘要: In an aspect, a tensioner is provided for tensioning an endless drive member that is engaged with a rotary drive member on a shaft of a motive device. The tensioner includes a base that is mountable to the motive device, a ring that is rotatably supported by the base in surrounding relationship with the shaft of the motive device and which is rotatable about a ring axis, a tensioner arm pivotally mounted to the ring for pivotal movement about an arm pivot axis, and first and second tensioner pulleys. The first tensioner pulley is rotatably mounted to the tensioner arm. The tensioner arm is biased towards a first span of the endless drive member on one side of the rotary drive member. The second tensioner pulley is rotatably mounted at least indirectly to the ring and is biased towards a second span of the endless drive member on another side of the rotary drive member. The ring is rotatable in response to hub loads in the first and second tensioner pulleys that result from engagement with the first and second spans of the endless drive member.
