A drive belt tensioning method and assembly using a spring loaded, non-active tensioner. The spring is mounted between a base plate, and a tensioner arm, both of which rotate. A belt tensioning pulley is mounted on the tensioner arm, such that the belt tensioning pulley is adjacent to the drive belt

A drive belt tensioning method and assembly using a spring loaded, non-active tensioner. The spring is mounted between a base plate, and a tensioner arm, both of which rotate. A belt tensioning pulley is mounted on the tensioner arm, such that the belt tensioning pulley is adjacent to the drive belt. The tension of the spring causes the tensioner arm to rotate which causes the belt tensioning pulley to tension the drive belt. The spring chosen has a predetermined working length at which the drive belt has the desired tension. Because both the base plate and the tensioner arm rotate, the spring may be kept at this predetermined working length for each belt adjustment. This enables the drive belt to maintain the desired tension. An alignment index integral to the assembly may be used to ensure that the spring is at the predetermined working length.
