Abstract
Official abstract text for this publication.
A belt tensioner having a tensioner base and a tensioning arm axially aligned about a pivot shaft defining a pivot axis, the tensioning arm pivotal in relation to the tensioner base about the pivot axis. The tensioner has a bearing positioned around and sealed against the pivot shaft, with the tensioning arm positioned around the bearing. The bearing forms a radial seal between the bearing and the tensioning arm and between the bearing and the pivot shaft. A torsion spring is positioned externally around a portion of the tensioning arm.
First claim
Opening claim text (preview).
What is claimed is: 1. A belt tensioner for a belt drive, comprising: a tensioner base and a tensioning arm axially aligned about a pivot shaft defining a pivot axis, the tensioning arm pivotal in relation to the tensioner base about the pivot axis, and a sealed pivot bearing positioned around and sealed against the pivot shaft, the tensioning arm positioned around the sealed pivot bearing, a damping mechanism, wherein a torsion spring and damping mechanism are positioned radial to the pivot shaft and having the tensioning arm positioned therearound, wherein the tensioning arm is axially positioned between the torsion spring and the sealed pivot bearing, and the torsion spring is axially positioned between the sealed pivot bearing and the damping mechanism, wherein the damping mechanism is configured to engage an inner radial wall of the tensing arm. 2. The tensioner of claim 1 , wherein the damping mechanism is secured to a second end of the torsion spring and a first end of the torsion spring is mated to the tensioning arm. 3. The tensioner of claim 2 , wherein the damping mechanism is positioned around the second end of the torsion spring.
