SUPPORT DEVICE OF ROLLING BEARING, AND VIBRATION INSPECTION APPARATUS WITH THE SAME

PROBLEM TO BE SOLVED: To provide a support device of a rolling bearing in which preload directions can be switched over by a necessary and sufficient preload, and no moment is applied to the rolling bearing even when applying the preload to the rolling bearing, and a vibration inspection apparatus with the same.SOLUTION: A support device of a rolling bearing comprises: a bearing holding member 31 which holds an inner ring of the rolling bearing W before insertion into an arbor 33 and includes a pusher 53; a holding member drive part which moves the bearing holding member 31 in the rotational axis direction; a first pressure member 57 which moves in the rotational axis direction capable of contacting with an outer ring; and a first pressure drive part which drives the first pressure member 57 to apply a pressure to the outer ring. The arbor 33 supporting the rolling bearing W includes: a fixed collar 131 and a movable collar 147 which protrude from an outer peripheral surface to outside in a radial direction; and a collar opening/closing drive part which performs opening/closing drive of the movable collar 147. The bearing holding member 31, the first pressure member 57, and the pusher 53 are coaxially arranged with the rotation axis of the arbor 33.SELECTED DRAWING: Figure 6 【課題】必要十分な予圧荷重で予圧方向を切り替え可能にすると共に、転がり軸受に予圧を付与した場合でも、転がり軸受にモーメントが作用することのない転がり軸受の支持装置、及びこれを備えた振転検査装置を提供する。【解決手段】転がり軸受の支持装置は、アーバ３３への挿入前の転がり軸受Ｗの内輪を保持しプッシャ５３を有する軸受保持部材３１と、軸受保持部材３１を回転軸方向に移動させる保持部材駆動部と、回転軸方向に移動して外輪に当接可能な第１加圧用部材５７と、第１加圧用部材５７を駆動して外輪を加圧する第１加圧駆動部と、を備える。転がり軸受Ｗを支持するアーバ３３は、外周面から径方向外側に突出する固定鍔１３１及び可動鍔１４７、及び可動鍔１４７を開閉駆動する鍔開閉駆動部を有する。軸受保持部材３１、第１加圧用部材５７、及びプッシャ５３を、アーバ３３の回転軸と同芯に配置した。【選択図】図６
