    摘要： A tensioner for tensioning engine driven driving elements, such as belts or chains, is disclosed. In accordance with one aspect of the invention, the tensioner is initially installed with the pivot structure spaced past the perpendicular angular position thereof. In accordance with another aspect of the invention, the tension required to move the pivot structure to the end of its range of angular positions is at least 75% more than at the hot engine angular position thereof. In accordance with another aspect of the invention, the tensioner has a stop at the maximum travel position thereof and the tension required to move the pivot structure to its maximum travel position is at least 75% more than at the hot engine angular position thereof. In accordance with a still further aspect of the invention, the tension required to move the pivot structure to a potential tooth skip angular position is greater than the maximum tension the engine is capable of creating.

    摘要： 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.

    摘要： 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.

    摘要： 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 of the tensioner arm is adjustable from a position suitable for installation of the tensioner to a position suitable for operation of the installed tensioner. In one embodiment, the movement of the stop from the installation position to the nominal operating position also compensates the spring.

    摘要： 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.
