Title:
ROTATIONAL ACCURACY/DYNAMIC TORQUE MEASURING DEVICE FOR RADIAL ROLLING BEARING
Document Type and Number:
Japanese Patent JP2000155073
Kind Code:
A
Abstract:

To measure the rotation asynchronous vibration and dynamic torque of a radial rolling bearing correlatively and accurately.

One bearing ring of a radial rolling bearing 1 is rotatively driven by a spindle shaft 10. An axial load is freely applied to a holder 23a holding the other bearing ring via a static pressure gas bearing 29a displaceably in the radial direction and rotating direction. The displacement in the radial direction of the holder 23a is measured by a displacement sensor 33. The torque applied to the holder 23a is measured by a torque sensor 40 via a wire 41.
