Abstract

PURPOSE:To keep off any resonance attendant upon high speed rotation of a spindle as well as to raise its critical speed by setting up a detector, detecting a rotational quantity of state in the rotational speed and position of the spindle, between first and second bearings. CONSTITUTION:A gearlike toothed ring plate 42 is attached to a spindle 10 by means of interference fit, and a bracket 46 provided with a hole where a speed detecting element 44 is inserted, is clamped to a casing 3 with a screw 50. And, the speed detecting element 44 inset in this bracket 46 is attached to a position to be opposed to the toothed ring plate 42, and it is positioned by a span ring 52 so as to make the opposed clearance with the toothed ring plate 42 so proper, then it is held and clamped to the position from the cross direction by a screw 48. Thus, since a speed detector is set up between bearings 24 and 16, a cantilever area to be overhung from a bearing part can be reduced as short as possible, and critical speed of a turning shaft is made to go up, thus the spindle 10 can be rotated at superhigh speed.
