Rotational accuracy and dynamic torque measuring device for rolling bearings |
| abstract |
(57) [Summary] [PROBLEMS] To relate the rotational asynchronous runout and dynamic torque of a rolling bearing 1 in both radial and axial directions to each other, In addition, it can be accurately measured freely. A rolling bearing (1) is provided by a spindle shaft (10). One of the bearing rings is rotationally driven. The axial load can be freely applied to the holder 23c holding the other raceway by the hydrostatic gas bearing 29a while allowing the holder 23c to freely move in the radial and rotational directions. And the holder 23c The radial and axial displacement sensors 49 and 50 can measure the displacement in both the radial and axial directions. Further, the torque applied to the holder 23c can be measured by a torque sensor via a wire. |
