An improved belt tensioning system 30 includes an improved tensioner 34 mounted on a fixed post 36. The improved tensioner 34 includes the body 37 having a bore 40 extending therethrough. Located in the bore 40 is an elastomeric material 42 having a Shore A durometer of between 30 and 50. Mounted within the bore 48 in the elastomeric material 42 is a bushing 44 that has a bore 46 therethrough sized to closely receive the post or shaft 36. The elastomeric material has damping characteristics capable of substantially eliminating resonant frequencies from the system. Location of the tensioner 34 on the fixed post or shaft 36 permits the appropriate tension to be applied in the system 30 and the driving auxiliary systems by the tensioner while avoiding the use of conventional belt tensioners 20 which may introduce vibrations or oscillations into the belt drive system.
