摘要： A tensioner for a power transmission belt that is adapted to be operated in an endless path and a method of making the same are provided, the tensioner comprising a support unit for being fixed relative to the belt, a belt engaging unit carried by the support unit and being movable relative thereto, a mechanical spring unit operatively associated with the support unit and the belt engaging unit for urging the belt engaging unit relative to the support unit and against the belt with force to tension the belt, and a fluid dampening unit operatively associated with the support unit and the belt engaging unit to dampen the movement of the belt engaging unit relative to the support unit in at least one direction of movement thereof, the fluid dampening unit comprising a rotary dampening unit and the support unit comprising a shaft. The rotary dampening unit and the spring unit are coaxially spaced apart and coaxially aligned on the shaft with the belt engaging unit having a portion thereof disposed between the rotary dampening unit and the spring unit and being rotatably carried by the shaft.

The rotary dampening unit and the spring unit are coaxially aligned. The support unit has an opening passing therethrough for receiving a fastening member that will fasten the support unit to a vehicle bracket or the like. The opening is disposed coaxially through the rotary dampening unit and the spring unit.

摘要： A tensioner for a power transmission belt which is adapted to be operated in an endless path and method of making same are provided and the tensioner comprises a rotatable idler pulley, a supporting assembly for rotatably supporting the pulley and urging same against the belt with a particular belt tensioning force with the assembly supported adjacent the belt, and a system for holding the assembly with the pulley urged against the belt, and wherein the holding system operates to lock the assembly at a fixed position immediately prior to moving the belt in its endless path and while the supporting assembly is applying the particular belt tensioning force to thereby determine a fixed center about which the pulley is rotated and the holding system operates to provide release of the assembly from the fixed position and hence the pulley from the fixed center only when the belt is stationary.
