    Abstract: A tensioner for tensioning a flexible drive means, such as a timing belt or chain, includes a pulley to contact the belt. The pulley is mounted on a tensioner arm and the tensioner arm can be rotated about a pivot shaft mounted to the tensioner by a spring. The axis about which the pulley rotates is spaced from the axis of the rotation of the tensioner arm with respect to the pivot shaft and the spacing of these axes of rotation results in the pulley moving through an eccentric towards or away from the belt when the tensioner arm is rotated. A stop is used to limit the range of movement of the tensioner arm between a desired range of movement defined by a free arm stop and a backstop. The position of the stop is adjustable by an installer. The angular range of movement installed tensioner. In one embodiment, the movement of the stop from the installation position to the nominal operating position also compensates the spring.

    Abstract: A tensioner for an endless belt comprising a stationary structure on which a pivotal tension arm with an idler pulley is mounted. A spring between the tension arm and the stationary structure acts to bias the pulley against the belt, thereby applying tension. The invention includes a one-way device that is operable in response to the extent of pivotal movement of the tension arm in the forward direction to establish different positions at which pivotal movement in the return direction is limited. A damping system is used to restrict pivotal movement of the tension arm as a result of sudden short-time vibratory movements or dynamic vibrations in cold conditions.

    Abstract: A timing belt tensioner for a motor vehicle engine comprising a pivot that is fixed relative to the motor vehicle engine. A tensioner arm is mounted for pivotal movement on the pivot. The tensioner arm has a friction surface disposed in friction sliding relation with an adjacent surface during the pivotal movement. A belt engaging pulley is mounted for rotation on the tensioner arm. A spring coupled with the tensioner arm biases the arm in a direction tending to force the pulley into tensioning engagement with the belt when the tensioner is installed on the motor vehicle engine. The spring biasing the arm into a working position maintains a predetermined range of tension in the belt during dynamic operating equilibrium of the belt. An anti-kickback stop mechanism is coupled with the arm and stops instantaneous kickback movement of the arm against the belt tensioning direction beyond when the arm is instantaneously moved away from the working position against the belt-tensioning direction in response to instantaneous tightening of the belt. The anti-kickback mechanism adjusts a location of the stop position based upon the working position of the arm.

    Abstract: A tensioner (10) features a backstop device (40) which allows free rotation of the pivot arm (20) in one direction but not the other. Reverse rotation is prevented by friction that is able to resist torque on the pivot arm (20) under ordinary operating conditions which otherwise could permit belt tooth-skip to occur. In disclosed embodiments, the backstop device (40) includes a stop sleeve (50) and a clamp holder (60) which are axially interlocked and are able to rotate relative to each other. A clutch spring (80) surrounds permits relative rotation between the stop sleeve (50) and the clamp holder (60) in one direction but not the other. A clamp (70) retained within the clamp holder (60) frictionally engages the pivot shaft. A viscous coupling may be used in place of the frictional clamp.

    Abstract: A belt tensioner for tensioning a drive belt or timing belt comprises an eccentric adjusting member having an end surface thereof constructed and arranged to be mounted directly in surface-to-surface engagement with respect to a belt tensioner mounting surface for an engine frame. A pivoted structure is mounted on the eccentric adjusting member for pivoted movement between a first position and a second position, and a belt tensioning pulley is mounted for rotational movement on the pivoted structure. A coil torsion spring is constructed and arranged to resiliently bias the pivoted structure in a belt tightening direction away from the first position and toward the second position, the eccentric adjusting member being movable during an installation procedure to move the pivoted structure against the bias of the coil torsion spring into a position wherein the belt tensioning pulley is disposed in predetermined static tensioning relation with the belt, at which point the eccentric adjusting member is to be manually fixed. The end surface of the eccentric adjusting member is in sliding surface-to-surface relation with the mounting surface during rotation of the eccentric adjusting member.
