A tensioner comprising a base comprising a first portion, an arm comprising a second portion, the arm pivotally connected to the base, a pulley journalled to the arm, a resilient member compressively disposed between the first portion and the second portion, the resilient member comprising a gap within which the first portion and the second portion are disposed, and the resilient member comprising a bore, the bore engaging the arm.
1. A tensioner comprising:
a base comprising a first portion;
an arm comprising a second portion, the arm pivotally connected to the base;
a pulley journalled to the arm;
a resilient member compressively disposed between the first portion and the second portion thereby damping arm oscillations by compression of the resilient member between the first portion and the second portion through pivotal movement of the arm;
the resilient member comprising a gap within which the first portion and the second portion are disposed;
the first portion and second portion held in contact by the resilient member when the tensioner is only in an unloaded condition; and
the resilient member comprising bore, the bore engaging the arm.
2. The tensioner as in claim 1 , wherein the resilient member describes a “C” shape.
3. The tensioner as in claim 1 , wherein the resilient member comprises either natural rubber or synthetic rubber or a combination thereof.
4. The tensioner as in claim 1 , wherein the first portion and the second portion are in contact for a predetermined operating condition.
