摘要

The system has a bearing (10) comprising a fixed internal ring (102) relative to a metal casing (4). A revolving external ring and a pulley (6) are rotatably connected to a driving shaft (2). A drive belt (8) is mounted on the pulley. A support (12) is mounted on the driving shaft and fixed at the revolving ring. The support is crimped at a circumference edge (1210) of the revolving ring in a position. An internal surface (66) of the pulley is in contact with the support. The support comprises a tubular portion extending parallel to a rotation axis. An independent claim is also included for a method for assembling a drive system for driving a water pump.
