Title (EN) KEYLESS IMPELLER SYSTEM AND METHOD
(FR) SYSTÈME À ROUE À AUBES SANS CLAVETTES ET PROCÉDÉ ASSOCIÉ
Abstract:
(EN) A compressor for a heating, ventilating, air conditioning, and refrigeration (HVAC & R) unit includes an impeller, a shaft configured to rotate the impeller, and a fastener. The impeller includes an opening and does not include keys, splines, pins, or any combination thereof. The fastener is coupled to an end of the shaft and extends through the opening of the impeller), and the fastener is configured to stretch in an axial direction relative to the shaft via a tensioner during assembly of the compressor.
(FR) L'invention concerne un compresseur destiné à une unité de chauffage, de ventilation, de climatisation et de réfrigération (CVC & R), le compresseur comprenant une roue à aubes, un arbre conçu pour faire tourner la roue à aubes, et un élément de fixation. La roue à aubes comprend une ouverture et ne comprend pas de clavettes, de cannelures, de broches ni des combinaisons de ces éléments. L'élément de fixation est accouplé à une extrémité de l'arbre et s'étend à travers l'ouverture de la roue à aubes, l'élément de fixation étant conçu pour s'étirer dans une direction axiale par rapport à l'arbre, par l'intermédiaire d'un tendeur, pendant l'assemblage du compresseur.
