すきまばめで取り付けた自由側玉軸受のアキシアル方向挙動観察

抄録

Rolling bearings are fixed at the both ends of a shaft. In order to avoid the effect of expansion of shaft by heat generation, clearance fit is designed between the outer ring and the housing. Thus, one end of the shaft can move to its axial direction. Though a recommended clearance according to the amount of load is listed in a trade catalogue, a free-end bearing may wreck due to axial unmoving of the shaft on ground of fixing inclination between the shaft and the free-end bearing. In this study, axial movement of free-end bearing caused by axial movement of shaft was observed with a simplified equipment. Consequently, the axial displacement, the load required for axial displacement, etc., was clarified.
