[0003] EP 1 395 759 B1描述了一种用于将轴支承在壳体上的轴承布置,包括支承所述轴的磁轴承和支承漉轴承,其中,支承漉轴承的轴承环在磁轴承的正常运行中相对轴保持支承漉轴承间隙。 [0003] EP 1 395 759 B1 describes a method for the shaft support bearing disposed on the housing, comprising a magnetic bearing supporting the shaft and the support bearings Luk, wherein the support bearing a bearing ring glistening magnetic bearing normal operation is supported relative to the shaft holding bearing gap Luk. 如果磁轴承失效,那么轴下落到支承漉轴承的内环内。 If the magnetic bearing fails, the drop shaft into the inner ring of the support bearing glistening. 为了避免高的轴向和径向的力,在壳体上固定第一中间元件并在支承漉轴承的外环上固定第二中间元件,其中,第二中间元件具有径向槽,在第一中间元件上的径向突出部嵌接在该径向槽内。 In order to avoid the high axial and radial forces, the first intermediate fixing element is fixed to the housing and on the support bearing outer ring glistening a second intermediate element, wherein the second intermediate member has a radial groove, in a first radially projecting portion on the intermediate element engages in the radial slots. 在该突出部和该槽之间设置有减震元件,运些减震元件应该能抑制从支承漉轴承向刚性壳体的力传递。 Disposed between the projecting portion and the groove damping element, the damping element to be transported can be suppressed more transferred from the support bearing force of glistening rigid shell.

发明内容 SUMMARY

[0004] 本发明的任务是提供一种具有支承漉轴承的轴承布置,借此,可W在该支承漉轴承内更好地吸收在负载情况下产生的力。 [0004] The object of the invention is to provide a bearing arrangement having a bearing supporting glistening, whereby W can better absorb forces generated under load in the bearing support Luk.

[0005] 根据本发明,该任务对于开头所述的轴承布置是如下运样完成的,即,在壳体内设置基本上在圆周方向上延伸的构造为贯穿部的缝隙。 [0005] According to the present invention, this object according to the start of the following sample transport bearing arrangement is completed, i.e., structure is provided which extends substantially in the circumferential direction to penetrate the slot in the housing portion.
