영문 초록

Modern machine tool spindles simultaneously require high stiffness and fast rotation characteristics for high speed, highly efficient processing, as well as for a wide range of use rotation. In order to this, a variable preload technology is needed so that the bearing that can apply a greater preload to raise the stiffness of the spindle at the low speed range and a smaller preload at the high speed range to reduce heat generation, as opposed to greater stiffness, and to allow high speed rotation. This paper propose the algorithm for determining the variable preload. For determination of a variable preload, the bearing life, rigidity, and the gyroscopic slip were considered as the constraint conditions. The bearing life was calculated by simultaneously considering the spindle rotational speed and external load.
