Abstract

A tensioner for tensioning a strand of chain between two sprockets including a tensioner body and a ramp fixed to ground. The tensioner body has an oval shape defined by first and second arcuately curved sides. Each side has a distal end, a proximal end, and a blade spring. The first and second arcuately curved sides are coupled together at the distal ends and pivotally attached to ground at the proximal ends. When the first arcuately curved side is in contact with the ramp, the second arcuately curved side is in contact with the chain strand, and the tensioner body is positioned relative to the ramp such that the blade springs of the tensioner body are compressed, a tensioning force is applied to the strand of chain.
