Pulley device for a chain or belt and motor vehicle equipped with such a device

摘要

The inventive pulley device for one of a chain and belt provides an inner ring, an outer ring, at least one row of rolling elements mounted in a rolling chamber defined between the inner ring and the outer ring, a pulley secured in rotation with the outer ring and provided with an outer radial surface for engagement with one of a chain and a belt. A screw for mounting on a support is housed radially inside the inner ring and a mounting support element is provided with a passage opening for the screw. The opening is tapped, with a complementary tapping of a thread arranged on the screw, the screw is provided with a groove, offset relative to the thread along a longitudinal axis (X40) of the screw and in which the tapping of the opening is received.
