ABSTRACT:
A vibration measurement system 1 comprises a shrink-type chuck 5, a spindle 14, and a servo motor 16 as mechanical elements, and has a vibration pickup 41 attached to the outer peripheral surface of a jaw 5a holding an outer ring 4 of a roller bearing 2. A ring groove 5b is formed on the inner face of the jaw 5a holding the bearing 2, and a shell 18 with oil pressure as back pressure is fitted into the ring groove 5b. When vibration is measured, the oil pressure of the shell 18 is raised to bring bearing clearance to zero, thereby preventing so-called roller drop from causing impulsive vibration.
