Rotating body clamping device

Abstract

Abstract PURPOSE: To maintain a spin tester in a centered state even when the tester is rotated at a high speed so that the tester can be fitted quickly to a rotating body by providing discoid or cylindrical centering means between a center shaft for rotating body and the rotating body. CONSTITUTION: A plurality of, desirably, two centering means 20 are provided between a center shaft 1 for rotating body and a rotating body 6 in the axial direction of the rotating body 6. The peripheral surfaces of the centering means 20 formed in discoid 22 or cylindrical bodies are divided by a plurality of dividing grooves 26 which are formed by cutting the peripheral surfaces in the radial directions and arranged in the axial direction at regular intervals. Therefore, the behaviors of peripheral areas 31 as springs can be matched accurately to the expanding behavior of the rotating body 6. To guarantee the centering actions of the centering means 20, at least three peripheral areas 31 are required. It is preferable, in addition, to provide four dividing grooves 36, namely, four peripheral areas 31 from the viewpoint of the behaviors of the areas 31 as springs and the manufacturing cost. Therefore, a spin tester can be maintained in a centered state even when the tester is rotated at a high speed. COPYRIGHT: (C)1989,JPO
