<P>PROBLEM TO BE SOLVED: To provide a device to hold a motor-driven work spindle in a housing of a processing machine, which protects against collision by removing the driven work spindle that is weak against physical impact from the force flow of the strong processing machine. <P>SOLUTION: The device has an outside ring 7, and an inside ring 6 arranged within the outside ring 7. The inside ring 6 is displaced and tilted axially to hold the work spindle, wherein the inside ring 6 is elastically pretensioned to the outside ring 7 in the axial direction by a pretension element and is held at an operating position within the outside ring 7 by a holding device with a specified holding force. The holding device is designed as a magnet arrangement with at least one magnet, which is arranged in the inside ring 6 and/or the outside ring 7, to create a magnetic holding force. <P>COPYRIGHT: (C)2012,JPO&INPIT |
