Abstract
A tensioner system for tensioning a power transfer member such as a chain or a belt is disclosed. In one example, the system includes a base adapted to rotate about a main shaft that is operatively coupled to a motor, a housing positioned around the main shaft and a plurality of deformable elastic members positioned within the housing. The system further includes a plurality of deforming members positioned within the housing around the main shaft, wherein the plurality of deforming members are adapted to be urged in a radially outward direction so as to deform the deformable elastic members.
Claims19
A tensioner system for tensioning a power transfer member used to transfer power from a motor to apparatus driven by the motor, the tensioner system comprising:
- a base adapted to rotate about a main shaft, wherein the base is adapted to be operatively coupled to the motor;
- a housing positioned around said main shaft;
- a plurality of deformable elastic members positioned within the housing;
- and
- a plurality of deforming members positioned within said housing around said main shaft, said plurality of deforming members adapted to be urged in a radially outward direction so as to deform said deformable elastic members.
