Description
本発明の着磁パルサリングは、環状のフランジ部を有し、かつ回転輪に対して一体回転可能に設けられる支持部材と、前記フランジ部の一側面に接着され、かつ周方向に所定間隔で配列された多数の磁極を有するとともにその磁極の変化が磁気センサによって検出される環状の永久磁石と、前記フランジ部に対する所定の接着位置に前記永久磁石を保持するための環状の保持部材と、を備えており、前記保持部材が、前記回転輪に一体回転可能に嵌合する筒状の嵌合部と、この嵌合部から径方向外方に延び、前記磁気センサの磁気検出範囲よりも径方向内側において前記永久磁石の軸方向及び径方向の移動を規制する規制部とを有し、前記保持部材の規制部に周方向に複数の切り欠きが形成され、前記永久磁石に、前記切り欠きに噛み合う突部が周方向に複数形成されていることを特徴とする。 The magnetized pulsar ring of the present invention has an annular flange portion and is provided so as to be integrally rotatable with respect to the rotating wheel, and is bonded to one side surface of the flange portion and arranged at predetermined intervals in the circumferential direction. An annular permanent magnet having a large number of magnetic poles that are detected by a magnetic sensor, and an annular holding member for holding the permanent magnet at a predetermined bonding position with respect to the flange portion. A cylindrical fitting portion that is fitted to the rotating wheel so as to be integrally rotatable with the rotating wheel, and extends radially outward from the fitting portion, and more radially than a magnetic detection range of the magnetic sensor. A restriction portion for restricting movement of the permanent magnet in the axial direction and the radial direction on the inner side, and a plurality of notches are formed in a circumferential direction in the restriction portion of the holding member, and the notch is formed in the permanent magnet. Bites Characterized in that it formed with a plurality but circumferentially.
前記保持部材の規制部には、周方向に複数の切り欠きが形成され、前記永久磁石には、前記切り欠きに噛み合う突部が周方向に複数形成されているので、切り欠きと突部とを噛み合わせることによって永久磁石が周方向に位置ずれてしまうことを防止することができる。 The restriction portion of the holding member, a plurality of notches in a circumferential direction is formed, and the prior SL permanent magnets, since projections meshing with the notch is formed with a plurality circumferentially, notches and collision It is possible to prevent the permanent magnet from being displaced in the circumferential direction by meshing with the portion.
