轴承、平的基板的加工单元、以及安装和移除旋转工具的方法
Abstract:
一种用于保持旋转加工工具（10,11）的轴承，包括两个端部滚动轴承装置（26,28）、至少一个位于所述两个端部滚动轴承装置（26,28）之间的中间滚动轴承装置（27）、以及至少一个机械致动器（32,33），所述端部和中间滚动轴承装置（26,27,28）用于与所述旋转工具（10,11）的端部（10a,10b,11a,11b）接合，所述机械致动器配置成对所述中间滚动轴承装置（27）施加径向预载力（Fo,Fo’）。
Abstract(English):

The invention relates to a bearing for supporting a rotary processing tool (10, 11), the bearing comprising two devices with end bearings (26, 28), at least one device with an intermediate bearing (27) disposed between the devices with end bearings (26, 28), the devices with end and intermediate bearings (26, 27, 28) being designed to cooperate with an end (10a, 10b, 11a, 11b) of the rotary tool (10, 11), and at least one mechanical actuator (32, 33) configured to exert a radial preload force (Fo, Fo') on the intermediate bearing device (27).
