The invention relates to an elastic mounting of a high-speed rotor, especially of high-spinning machines. The shaft supporting the elastic mounting has a pressed-on spinning rotor at its one end, the other shaft end being trued for the attachment of a belt pulley. According to the invention, the central bush 1 engages into the rubber members 2, 3 on the spinning-rotor side and on the belt-pulley side, the rigidity of the rubber member 2 located on the belt-pulley side being higher than that of the rubber member 3 located on the spinning-rotor side. The combination of the rubber members 2, 3 of differing rigidity achieves an optimum dynamic balancing of the spinning rotor. The mounting according to the invention is suitable for fine-spinning machines having rotor speeds above 60,000 min<-1>. <IMAGE> |
