20140364258 | SYSTEM FOR DRIVING A WATER PUMP AND MOUNTING METHOD - The present invention provides a system for driving a water pump. The system includes a driveshaft, a case containing the water pump, a bearing including a stationary ring that is stationary relative to the case and a rotating ring secured in rotation with the driveshaft. The system further includes a drive belt, at least one rolling path for the drive belt, the rolling path being secured in rotation with the rotating ring, and a flange transmitting the torque from the rotating ring to the drive shaft. The flange is made from plastic and is overmolded both on the rotating ring and on the driveshaft. The invention also relates to a mounting method for such a system. | 12-11-2014 |
20150267790 | IDLER OR ROLLER DEVICE - A tension roller or reel device for a torque transmission element. The device comprises at least one bearing having one inner race, one outer race and at least one row of rolling elements between the inner race and the outer race, a pulley on top of the outer race, and a retaining screw inserted into a central bore of the inner race. The bore of the inner race is provided with a circumferential cavity in which a retaining ring is fitted securely and integrally, the retaining ring comprising an interaction feature providing interaction with the screw so as to allow an axial immobilization of the screw in relation to the bearing. | 09-24-2015 |
20150267791 | IDLER OR ROLLER DEVICE - A tension roller or reel device for a torque transmission element. The device comprises at least one bearing having one inner race, one outer race and at least one row of rolling elements between the inner race and the outer race, a pulley on top of the outer race, and a retaining screw inserted into a central bore of the inner race. The bore of the inner race is provided with a circumferential cavity in which an elastic ring is fitted non-securely and integrally, the cavity having an axial length strictly greater than the axial dimension of the elastic ring. | 09-24-2015 |
20150300463 | IDLER OR ROLLER DEVICE - A tensioning roller/winder device comprising at least one roller bearing including inner and outer rings and at least one row of rolling elements between the two rings; a pulley surmounting the outer ring; and a retaining screw comprising a body and head. An abutment is provided on the body external periphery. First and second abutments are provided on the inner ring bore. The axial length between the head and the abutment equals the axial length between an inner ring radial side edge and the inner ring bore first abutment is greater than the axial length between a inner ring radial side edge opposite the screw head and the inner ring bore second abutment. The screw abutment contacts the inner ring first abutment during the body insertion into the inner ring bore in the desired direction, but contacts the inner ring second abutment during the body insertion in the undesired direction. | 10-22-2015 |
20160017963 | TENSIONING DEVICE FOR A TRACTION MEMBER - A tensioning device for a traction member, such as a belt, for an internal combustion engine, the tension device comprising a pulley rotatably mounted on an eccentric hub also rotatably mounted on a shaft. One end of the shaft comprises a shoulder against which abuts a plate for attaching the device onto the internal combustion engine. The tensioning device further comprises a torsions spring mounted around a tubular portion of the hub extending along a longitudinal direction of the hub between the hub and the attachment plate. The tensioning device also comprising a spring holder interposed between the spring and the attachment plate. An end turn of the spring is attached around an axial portion of the spring holder. | 01-21-2016 |
20160017977 | PULLEY DEVICE FOR CHAIN OR BELT - A pulley assembly comprising an inner ring, an outer ring, at least one row of rolling elements between the inner and outer rings, a pulley rotationally secured with the outer ring, having an outer radial surface for engagement with a chain or belt, a screw comprising a head and a stem radially housed inside the inner ring and having an outer peripheral groove, a mounting support element having a receiving bore or housing for receiving the screw head and an axial retaining member retaining the screw stem within the receiving housing, the member being engaged in the outer groove of the screw stem. The mounting support element includes a cavity that emerges in the receiving bore. When the screw is installed within the receiving bore, the outer groove is axially across from the mounting support element cavity and the axial retaining element is engaged in the mounting support element cavity. | 01-21-2016 |
