    • 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.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.
    • 要解决的问题:提供一种将电动机驱动的工作主轴保持在加工机械的壳体中的装置,该装置通过去除不受物理冲击而受到的物理冲击的抵抗力的动作,从而防止碰撞 强力加工机。 解决方案:该装置具有外环7和布置在外环7内的内环6.内环6被轴向位移并倾斜以保持工作主轴,其中内环6弹性预张紧到 外环7通过预紧元件在轴向方向上,并通过具有指定保持力的保持装置保持在外环7内的操作位置。 保持装置被设计为具有设置在内环6和/或外环7中的至少一个磁体的磁体布置,以产生磁力保持力。 版权所有(C)2012,JPO&INPIT
