DISPOZITIV SUPORT PENTRU ROTOARE LA MASINI RAPIDE DE CABLARE CU MAI MULTE VITEZE

摘要

The arrangement of the bearings of the rotors in a multi-stage high speed cabling machine, in which the separate rotors are assembled in a common housing side by side or one above the other, and are separately driven, has, between the outer ring of the roller bearing on the journal of the rotor, and the seat of the bearing housing, a bearing bush consisting of three sleeves one inside the other. The middle sleeve of the three is a relatively thin-walled tube of an elastic material, e.g. 'Syspur' (RTM), and to prevent any build up of heat in the roller bearing due to the lack of metallic contact, between bearing housing and housing cover an annular cavity is provided to form a zone through which air circulates with a whirling motion. Reduces the noise and vibration levels to within reasonable limits and combines a satisfactory dispersal of heat generated in the bearings with their efficient lubrication.
