    • A rotor centering device comprising two radial bearings each one constituted of first and second opposing members with angular contact races, mounted with axial clearance so that if one of the said members is in abutment, the other member has a radial clearance. The first angular contact centering members of the first and second bearings are also opposing, and the second angular contact centering members of the first and second bearings are likewise opposing, so that by relative axial movement of the inner and outer contact races of both first and second centering means belonging to the two bearings, simultaneous contact of the inner and outer faces is achieved either with the first centering members or with the second centering members which happen to be opposing on the two bearings.
    • 一种转子定心装置,包括两个径向轴承,每个径向轴承每个由具有角接触圈的第一和第二相对构件构成,安装有轴向间隙,使得如果所述构件中的一个抵接,则另一个构件具有径向间隙。 第一和第二轴承的第一角接触定心构件也是相对的,并且第一和第二轴承的第二角接触定心构件同样相反,使得通过第一和第二轴承的内外接触轨道的相对轴向运动, 属于两个轴承的第二对中装置,内外表面的同时接触可以通过第一定心构件或与在两个轴承上相对的第二定心构件实现。
