Title (EN) CENTERING RING BEARING ELEMENT AND METHOD FOR CENTERING A SHAFT
(FR) ELEMENT DE PALIER A BAGUE DE CENTRAGE ET PROCEDE DE CENTRAGE D"UN ARBRE
Abstract: front page image
(EN)The invention refers to cylindrical bearings for guiding a shaft. Each bearing element comprises a centering ring (4) made of a material having a thermal expansion coefficient higher than that of the material of the shaft (1), for example polytetrafluoroethylen arranged substantially coaxially to the shaft with a play such that upon an appropriate cooling, the ring hoopes to the shaft. The method for the relative centering of the shaft (1) and the bearing comprises then a cooling step down to a temperature such that the ring (4) is hooped to the shaft. Then, each bearing element is motionless and fixed. Application to pumps.
(FR)Les paliers cylindriques a coussinet pour le guidage d"un arbre. Selon l"invention chaque element de palier inclut une bague de centrage (4) en materiau ayant un coefficient de dilatation thermique superieure a celui de materiau constituant l"arbre (1), par exemple en polytetrafluoroethylene dispose sensiblement coaxialement a l"arbre avec un jeu tel que lors d"un refroidissement approprie, la bague vienne se fretter sur l"arbre. Le procede de centrage relatif de l"arbre (1) et du palier comprend alors une etape de refroidissement jusqu"a une temperature telle que la bague (4) soit frettee sur l"arbre. A ce moment chaque element du palier est immobilise et fixe Application aux pompes.
