Abstract
Aspects of the present invention generally provide tensioner for varying tension applied to a continuous drive member based on temperature changes. In one embodiment, a temperature compensating chain tensioner is provided. The temperature compensating chain tensioner includes a fixed support member, a first idler sprocket coupled to the fixed support member, a support arm having a proximal end pivotably coupled to the fixed support member, a second idler sprocket coupled to a distal end of the support arm, and a spring form coupled intermediate of the fixed support member and the support arm, wherein the spring form has a spring constant that increases with increasing temperature, which causes the distal end of the support arm to move relative to the fixed support member.
