Abstract

A tensioner comprising a base having a cylindrical portion extending axially, the cylindrical portion comprising a radially outer surface and a receiving portion that is radially inward of the radially outer surface, an eccentric arm pivotally engaged with the radially outer surface, a torsion spring disposed within the radially inward receiving portion, the torsion spring applying a biasing force to the eccentric arm, and a pulley journalled to the eccentric arm.

First claim

I claim:

1. A tensioner comprising:
a base cylindrical portion having a radially outer surface and a radially inward receiving portion;
an eccentric arm pivotally engaged with the radially outer surface;
a torsion spring disposed within the radially inward receiving portion, the torsion spring applying a biasing force to the eccentric arm; and
an elongate member engaged with the eccentric arm and disposed to pivot is response to a rotation of the eccentric arm.

2. The tensioner as in claim 1 , wherein the eccentric arm and the torsion spring are concentrically arranged such that no one of the eccentric arm or torsion spring is axially displaced along an axis A-A from the others.

3. The tensioner as in claim 1 , wherein the eccentric arm is journalled to the base on a bushing.

4. The tensioner as in claim 1 , wherein a pulley is journalled to the eccentric arm on a needle bearing.
