Claims (1)
外輪側を磁性体からなるケース体に配設したホルダーに
固着し、このボールベアリングの内輪側に前記回転軸を
挿通し、この内輪側を軸方向に付勢して予圧を付加する
機構において、前記ボールベアリングを少なくとも前記
回転軸の出力側に位置する前記ケース体に配設すると共
に、前記回転軸に固着した回転体の永久磁石を前記ケー
ス体の軸方向と直角に面対向させ、この永久磁石と前記
ケース体との吸引力により回転軸を一方向に付勢して前
記ボールベアリングの内輪側に予圧を付加してなるモー
タ用軸受装置における予圧付加機構。The outer ring side of a ball bearing that supports a rotating shaft to which a rotor is fixed is fixed to a holder provided in a case body made of a magnetic material, and the rotating shaft is inserted into the inner ring side of this ball bearing, and this inner ring side is attached to the shaft. In the mechanism for applying preload by applying force in a direction, the ball bearing is disposed at least in the case body located on the output side of the rotating shaft, and a permanent magnet of the rotating body fixed to the rotating shaft is attached to the case body. A bearing device for a motor in which the rotating shaft is biased in one direction by the attractive force between the permanent magnet and the case body, and a preload is applied to the inner ring side of the ball bearing. Preload addition mechanism.
