Title (EN) COMPRESSOR WITH DUAL OUTBOARD SUPPORT BEARINGS
(FR) COMPRESSEUR DOTÉ DE DOUBLES PALIERS-SUPPORTS EXTÉRIEURS
Abstract:
(EN) A compressor includes a motor having a rotor mounted to a free end of a crank shaft and a stator in a motor housing, and a bearing assembly supporting the crank shaft on the crank shaft housing adjacent the motor housing. The bearing assembly includes a bearing housing mounted to the crank shaft housing and including a bore; and a pair of spaced bearings mounted in the bore of the bearing housing and receiving the crank shaft. The space between the bearings is selected to allow the free end of the crank shaft to deform in synchronization with the movement of the stator and maintain a gap between the rotor and stator over the operating range of the motor.
(FR) Le compresseur selon la présente invention inclut un moteur équipé d'un rotor monté sur une extrémité libre d'un vilebrequin et d'un stator dans un carter de moteur, et un ensemble de palier supportant le vilebrequin sur le logement de vilebrequin adjacent au carter de moteur. L'ensemble de palier inclut un logement de palier monté sur le logement de vilebrequin et incluant un alésage ; et une paire de paliers espacés montés dans l'alésage du logement de palier et recevant le vilebrequin. L'espace entre les paliers est sélectionné de manière à permettre à l'extrémité libre du vilebrequin de se déformer en synchronisation avec le mouvement du stator et de maintenir l'espace entre le rotor et le stator sur la plage de fonctionnement du moteur.
