Abstract
L'invenzione concerne un cuscinetto ad alta velocità con lubrificazione interna per il rotore di un filatoio in fino, costituito da un guscio, un albero, due serie di corpi di rotolamento guidati tramite gabbie massicce, ed è provvisto, alle estremità, di dischi di tenuta e copertura. Il guscio consiste di almeno due parti collegate tramite saldatura, che terminano con flange sui loro lati opposti in contatto. Il diametro interno di almeno una flangia è minore del diametro esterno della gabbia. Fra le flange e la pista esterna è formata, nelle parti del guscio, almeno un'apertura di montaggio. Fra le due serie di corpi di rotolamento è previsto un tubo, con un incavo di fronte all'apertura di montaggio. Fra il tubo e la superficie interna delle parti di guscio vengono formate intercapedini per il lubrificante.The invention relates to a high speed bearing with internal lubrication for the rotor of a fine spinning machine, consisting of a shell, a shaft, two sets of rolling bodies driven by massive cages, and is equipped, at the ends, with sealing and covering. The shell consists of at least two parts connected by welding, which end with flanges on their opposite sides in contact. The internal diameter of at least one flange is smaller than the external diameter of the cage. At least one mounting opening is formed in the parts of the shell between the flanges and the outer race. A tube is provided between the two sets of rolling bodies, with a recess in front of the mounting opening. Gaps are formed between the tube and the internal surface of the shell parts for the lubricant.
