INSTALLATION SHAFT ASSEMBLY

摘要

A tensioner for a synchronous or non-synchronous drive system of a motor vehicle engine. The tensioner has an installation shaft with an aperture for receiving a bolt for affixing the tensioner to a motor vehicle engine. The aperture has a center that is offset from the first axis of rotation of a tensioner arm. The stamped installation shaft has a guide portion and an integrally formed plate portion. The plate portion extends transversely from the guide portion. The guide portion extends into the pivot shaft on which the tensioner arm is pivotally mounted. A distal end of the guide portion engages the pivot shaft in a manner which enables rotational movement and which prevents axial movement therebetween. The guide portion is configured to maintain offsetness of a distal end of the guide portion as the offsetness of the center of the aperture when the tensioner is installed on an engine.
