Belt drive for internal combustion engine, belt guided at pulleys and guide roller, which can rotate from loose position, in which roller does not clamp belt, into clamping position, in which roller clamps belt and can be locked, at axis

摘要

The drive has a flexible belt guided at belt pulleys and a guide roller (6), which is arranged rotatably arranged on a position fixed base plate (16). The base plate is arranged or can be fixed on a third object such as motor. The guide roller can rotate from a loose position, in which the roller does not clamp the belt, into a clamping position, in which the roller clamps the belt and can be locked, at an eccentric rotation axis. The roller has a bearing (9) in which an eccentric (12) is pressed in. An independent claim is also included for a guide roller for a belt drive.
