Abstract
A belt or chain tension producing apparatus comprises a tension head engageable with a chain, belt or the like of a chain or belt drive and a tension piston on which the tension head is carried. The tension piston is guided longitudinally slidable in a guide body which is simultaneously a mounting element and is acted on by at least one tension spring engaged with it which is supported at its other end on the base of the guide body. In order to provide a particularly compact structure and thus also a more universal structure, at least a part of one side of the tension piston projects laterally from the guide body and the tension head is mounted laterally on a mounting surface on that projecting part. A recess may be provided in the tension head to better mount it on the tension piston.

In a belt or chain tensioner comprising a tension head engagable with a stretch of endless member to be tensioned and a tension piston on which said tension head is carried, said tension piston being guided longitudinally slidable in a guide body which is simultaneously a mounting element and said tension piston being acted on by at least one tension spring engaged therewith which is supported on the base of said guide body, the improvement wherein at least a part of one side of said tension piston projects laterally from said guide body and said tension head is mounted laterally on said part of said side of said tension piston so that said head being in a plane parallel to but spaced from a plane of said piston of said spring, and said guide body is provided with two opposing guide columns and small sides of said tension piston positioned between said guide columns two correspondingly shaped guide grooves are provided, and wherein said guide body is provided with a guide housing engaging said tension piston, said housing being a substantially C-shaped bent flat bar having said base and a top piece between which said guide columns extend.
A belt or chain tension producing apparatus comprising:
- a tension head engagable with a chain, belt or the like;
- a substantially parallelepiped shaped tension piston on which said tension head is carried;
- a guide body in which said tension piston is guided longitudinally slidable which is simultaneously a mounting element;
- at least one tension spring acting on said tension piston supported on the base of said guide body;
- a projecting mounting surface oriented parallel to the travel direction of said tension piston on a part of a slide of said tension piston which projects laterally from said guide body on which said tension head is detachably mounted;
- a lateral recess in said tension head in which said projecting mounting surface present on said piston fits;
- and
- two opposing guide columns provided in said guide body and on the small sides of said tension piston position between said columns two correspondingly shaped guide grooves are provided for each of said guide columns.
