。In this bearing device, the inner ring 10 was made of ceramic, and the spacer 50 was made of steel. These spacers 50 each have an inner ring 1
In the rolling bearing device, the taper of the inner ring 10 and the spacer 50 is connected to the shaft 60 and the spacer 50 by the thermal expansion of the shaft 60 and the spacer 50. The aim was to appropriately determine the relationship between the coefficient of thermal expansion and the coefficient of thermal expansion of the ceramic inner ring 10, and to always maintain a constant interference in the tapered portion even with changes in temperature.

ならない。[Problem 1 to be Solved by the Invention] In a single rolling bearing as described above, the surface pressure due to the interference of the tapered portion generates a tensile stress T that tends to expand the inner ring 10 in the radial direction. In addition, the coefficient of thermal expansion is not constant depending on the temperature, so if an appropriate interference is given for a certain temperature, the interference will change as the temperature changes, resulting in excessive interference or gaps. The performance is not as expected.

ーパの精度の悪さはそのまま回転軸に対する内輪の傾き
となり、軸受の性能を劣化させる等の問題があった。Furthermore, at high speeds, the spacer 50 does not expand due to centrifugal force. Furthermore, taper machining is generally difficult machining, and the poor precision of the taper directly causes the inner ring to tilt with respect to the rotating shaft, resulting in problems such as deterioration of bearing performance.

I#i or the threaded part formed on the sleeve-shaped part of the sleeve,
In the rolling bearing vc arrangement of this invention, the bearing ring is positioned by the stepped portion and the nut, and the inner ring of the rolling bearing is fitted with a sleeve or a sleeve in which the bearing ring is easily elastically deformed. Since the sleeve is supported by the sleeve, any increase or decrease in tightness due to the difference in thermal expansion coefficients between the bearing ring and the shaft is absorbed by the elastic deformation of the sleeve or sleeve-like portion, and extreme stress is generated on the bearing ring. The fit will not become too loose.

、常に適度の嵌合状態が維持される。In the above-mentioned rolling bearing device, during rotational use, the allowance between the inner ring and the mating shaft, or more precisely, the increase or decrease in the interference between the inner ring and the sleeve-shaped part, is absorbed by the elastic deformation of the sleeve-shaped part. Therefore, no abnormal stress is generated in the inner ring, and the fit does not become a loose fit, so that an appropriate fitted state is always maintained.

半径方向の支持は、前記の残余の部分８２による。In the second embodiment shown below, a sleeve 8 is attached to a pongee 7 having a linear expansion coefficient different from that of the inner ring of the rolling bearing, and a bearing male screw 72 is provided in which the inner ring 1 of the bearing is fitted into the sleeve 8. A pair of sleeves 8 having the same shape are attached to the outer peripheral portion 73 of the shaft 7. The pair of sleeves 8 are provided with slotted notches 81 so as to be easily elastically deformed, but the slotted notches 81 are more slender than the slotted notches in the first embodiment. The range is much wider,
The width of the notched part is wider than the remaining part 82, and the large diameter part f1 of the pongee 7 and the R neck part 2 of the shaft 7 are screwed into the pongee 7 so that the remaining part 82 intersects. It is attached by a matching nut 9. Furthermore, in the sleeve 8,
A step 83 is provided for positioning the inner ring 1 of the rolling bearing. The rolling bearing is held between the stepped portions of the pair of sleeves 8 and positioned in the axial direction, and the remaining portion 82 supports the inner ring in the radial direction.
