摘要： A chain tensioner is disclosed which incorporates a blade tensioner and a rigid tensioner arm. The blade tensioner and rigid tensioner arm can be pivotally supported on proximate support structure and the blade tensioner urges the rigid tensioner arm into engagement with a portion of a chain to tension the chain. Alternatively, the blade tensioner can be pivotally mounted on the rigid tensioner arm. Two or more blade tensioners can be used to tension the rigid tensioner arm. If desired, the rigid tensioner arm can be mounted on one of the blade tensioners.

摘要： A tensioner for a power transmission system includes two tensioning arms operatively engaged with a strand of either the chain or the belt of the power transmission system. The upper end of each tensioning arm is connected to a one way rotational clutch which is pivotally mounted between the upper ends of the tensioning arms. The one way clutch rotates in one direction in response to changing chain loads to adjust the tension substantially equally on both strands at the same time. In order to prevent over-tensioning, a damping means is included in the one-way clutch. When a pre-determined overload threshold is reached, the amount of torque required to overcome the coefficient of friction of a spring in the damper allows the one way clutch to slip in the direction opposite from its normal rotational direction, thereby relieving the overload condition on the chain.

摘要： A camshaft assembly for an internal combustion engine has a hollow outer shaft with slots along its length and an inner shaft with holes along its length. The holes on the inner shaft are aligned with the slots on the outer shaft. A first set of cam lobes are fixed to the outer shaft and a second set of cam lobes are placed on the slots of outer shaft with a clearance fit. A means fixes the second set of cam lobes to the inner shaft, while simultaneously allowing the second set of cam lobes to be a clearance fit to the outer shaft. The means fixing the second set of cam lobes to the inner shaft may be a hollow pin which is hydroformed or a rivet insert which is expanded by insertion, pulling, and removal of a threaded rod.

摘要： A tensioner for imparting tension to a chain in a closed loop chain drive system of an internal combustion engine is disclosed. The tensioner contains two tensioning devices, one for each strand of chain that traverses between a drive sprocket and at least one driven sprocket. The two tensioning devices are installed on a single bracket which is mounted to the engine housing at a single dampened pivot mount. The pivot mount is positioned equidistant from the mid points along the lengths of each of the chain sliding surfaces of each of the tensioning devices to substantially form an isosceles triangle.

摘要： An engine tensioning system including a pair of pivoting arms used to simultaneously tension two separate strands of the same chain in an engine timing system. The tensioner system includes a lever. The lever has a pair of fixed pins attached to an end located between the two strands of chain. The arms extend outside separate strands of the chain and carry shoes positioned to contact an outside portion of the chain are pivotally mounted to the fixed pins. Rotation of the lever causes the fixed pins to move laterally with respect to the chain strands and cause the arms to draw inwardly. The inward movement of the arms draw the shoes into contact with the chain strands and impart tension to the separate strands of the chain simultaneously.
