POSITION ADJUSTING DEVICE FOR ROTOR
Document Type and Number:
Japanese Patent JP3418571
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize the positional adjustment of a rotor such as a holder with high accuracy and at the same time, maintain the positional adjustment at a high accuracy level for a long time.
SOLUTION: This position adjusting device has a guide 16 with a V-section formed on the outer periphery of a holder 3a, 3b as a rotor supported, in a freely movable manner, by rotating shafts 2a, 2b. In addition, fitting rollers 27 with a V-section are supported, in a freely rotating manner, on shifters 22, 25 which are movable along guide shafts 20, 23 and the movement of the shifters 22, 25 is transmitted to the holders 3a, 3b by bringing the tapered faces, on both sides, of the fitting rollers 27 into contact with the inclined faces, on both sides, of the guide 16. Friction is prevented from being generated in the contact part between the fitting roller 27 and the guide 16 by bringing the fitting roller 27 into contact with each of the holders 3a, 3b to rotate during rotating the holders 3a, 3b.
