Belt roller module for heat engine of motor vehicle, has screw including interface for fixing belt roller inside slot, where roller is immobilized with respect to screw, and diameter of fixation interface is higher than diameter of roller

摘要

The module (18) has a fixation screw (20) for fixing a slot of a belt e.g. timing belt. The screw has a fixation interface (22) for fixing a belt roller (24) e.g. tension roller or winder roller, inside the slot. The belt roller is axially immobilized with respect to the screw, where the diameter of the fixation interface is higher than the diameter of the belt roller. Threads (26) are formed on the fixation interface. An independent claim is also included an engine comprising a belt roller module.
