ABSTRACT:
A drive belt tensioning method and assembly using a dual spring tensioner. A pulley from a drive belt/pulley system is mounted onto a pivot arm having a pivot point. A tensioner spring mounts between the machine frame and the pivot arm, such that is causes rotation of the pivot arm about the pivot point in the opposite direction that the belt/pulley system causes rotation about the pivot point. A stop is used to keep the pivot arm in the position of tensioner spring/belt/pulley system equilibrium. This stop is mounted to the machine frame after the pivot arm equilibrium is reached. A retainer spring mounts between the machine frame and the pivot arm such that when in tension it causes a rotational force about the pivot point in the same direction that the tensioner spring causes a rotational force about the pivot point.
