Abstract
A tensioner is used for reducing the slack of an endless belt wound between a driving rotating body mounted on a drive shaft and a driven rotating body mounted on a driven shaft. A tensioner comprises a base part having a sliding member fitted to the drive shaft or driven shaft with a frictional force, an arm part extending from the base part to a relaxed traveling line which is the return side line from the driving rotating body to the driven rotating body, and a contact member affixed to the arm part and abutting against the relaxed traveling line of the endless belt.
Claims2
A tensioner for reducing the slack of a relaxed traveling line of an endless belt for forming a power traveling line to transmit power as being applied on a driving rotating body mounted on a drive shaft and a driven rotating body mounted on a driven shaft and a return side relaxed traveling line between the rotating bodies, consisting of
- a base part mounted on the drive shaft or the driven shaft and receiving the rotational moment acting in the same direction as the rotation of said shaft;
- an unitary arm part extending from the base part toward the relaxed traveling line of the endless belt, and
- a contact member affixed to the arm part, abutting against the relaxed traveling line of the endless belt and pushing said relaxed traveling line by said moment so as to reduce the slack thereof;
- said base part having a sliding member which generates said moment by press contacting against said shaft with a frictional force.
