Safety bearing for rotor shaft of textile rotor and bearing device having front safety bearing and rear safety bearing

The invention relates to a safety bearing (10, 12) for a rotor shaft (3) of a textile rotor (2). The textile rotor (2) is supported in a magnetic bearing (6). The safety bearing has a bearing element(8) made of a wear-resistant material, which is designed to cooperate with a bearing surface (5, 15) of the textile rotor (2). The safety bearing comprises a damping element (9), in which the bearingelement (8) is accommodated. According to the bearing device for a rotor shaft (3) of a textile rotor (2), the textile rotor (2) is supported in the magnetic bearing (6), the bearing device has a bearing housing (16), a front safety bearing (10) and a rear safety bearing (12). The bearing device has at least one safety bearing (10, 12) as described. 用于纺织转子（2）的转子轴（3）的安全轴承（10、12），所述纺织转子支承在磁性轴承（6）中，所述安全轴承具有由耐磨材料制成的轴承元件（8），所述轴承元件构造用于与所述纺织转子（2）的轴承表面（5、15）协同作用，所述安全轴承包括阻尼元件（9），所述轴承元件（8）容纳在所述阻尼元件中。用于纺织转子（2）的转子轴（3）的轴承装置，所述纺织转子支承在磁性轴承（6）中，所述轴承装置具有轴承壳体（16）、前安全轴承（10）和后安全轴承（12），所述轴承装置具有如所描述的至少一个安全轴承（10、12）。
