摘要： PROBLEM TO BE SOLVED: To provide a device which improves the accuracy of a balance in a rotor 1 and shortens the time necessary for making the balance of the rotor 1.
SOLUTION: An unbalance measurement device is one with the rotor 1 supported axially by a bearing device using a static fluid. In the bearing device, a circumferential face of a rotating shaft of the rotor is supported at least two opened bearing shells 11, 11' which are supplied with the fluid. The device also has two bearing plates 12, 12', supplied with the fluid, and abutted against the ends of the rotating shaft of the rotor. A driving device 5 is separated, when the unbalance measurement process of the rotor 1 is performed. Preferably, the measurement process is performed, under the rotational behavior of the rotor 1 which varies with the passage of time.

摘要： PROBLEM TO BE SOLVED: To provide a supporting device for making possible to conduct a high precision dynamic balancing test for a rotor without a journal. SOLUTION: A bearing mandrel 5 has openings 10, 20 for supplying fluid. In addition, an introduction pipe 11 for supplying the fluid is provided in a fluid chamber 40 separated by an upper end surface 16 of the bearing mandrel 5 and a bottom surface 17 of a rotor hole 6. The rotor 2 supported by the bearing mandrel 5 is supported with a fluid cushion by the fluid in the fluid chamber 40 in an axial direction. With this supporting device, imbalance of the rotor 2 with a bottomed hole 6 can be inspected at a high precision. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a method for precisely performing a balance test and its apparatus, for a rotor which is not equipped with any journals, and has a bearing hole instead in a shape of not stretching to the whole of an axial direction.
SOLUTION: A bearing mandrel 5 insertable into the bearing hole 6 of the rotor 2 is provided. The mandrel 5 is provided with a first bearing region 7 and a second bearing region 8 separated axially. To the first and second regions 7 and 8, liquid fluid is supplied from inside the bearing mandrel 5. The friction and gap between the bearing mandrel 5 and the bearing hole 6 of the rotor 2 into which the bearing mandrel 5 is inserted are absorbed with the supplied fluid. Consequently, the rotor 2 can be rotated smoothly, and unbalance of the rotor 2 can be measured.
