SUPPORTO PER ROTORE DI FILATURA CON DISPOSITIVO DI LUBRIFICAZIONE.

摘要

A bearing assembly for supporting the shaft of a spinning rotor is provided having a housing in which a pair of roller bearings are mounted spaced from each other along the shaft and which journal the shaft. Interposed between the roller bearings and surrounding the shaft is a sleeve in the form of a tubular member provided with at least one capillary channel formed between the inner and outer surfaces and extending longitudinally between its frontal ends. At least one hole extends from the outer surface radially inward in communication with the capillary channel. In this manner lubricant supplied to the housing exterior of the sleeve will pass through the hole and the capillary channel into direct contact with the roller bearings.
