Abstract
A blade tensioner includes a blade shoe assembly with parallel stacked flat springs that pivots at one end and is supported in series by a spring loaded ramp at the opposite end. Providing a spring loaded ramp in series reduces the overall stiffness of the tensioner which enables a more uniform tensioning load as the tensioner takes up chain slack due to elongation from wear.
