Description
本発明は、角度センサ一体型滑り軸受に関し、特に、滑り軸受に角度センサを内蔵させることにより、電動パワーステアリング用モータ、発電機、スターターモータ、位置決め用モータ等の軸受の角度センサで回転検出し、小型化等を達成するための新規な改良に関する。 The present invention relates to an angle sensor-integrated slide bearing, and in particular, by detecting the rotation with an angle sensor of a bearing such as an electric power steering motor, a generator, a starter motor, or a positioning motor by incorporating the angle sensor in the slide bearing. The present invention relates to a new improvement for achieving miniaturization and the like.
従来、用いられていたこの種の滑り軸受としては、電動パワーステアリング等における滑り軸受には回転センサは内蔵されておらず、駆動用のモータが、例えば、特許文献１及び２で示されるモータエンコーダで構成されるか、又は、モータの外側に特許文献３で示されるＶＲレゾルバを設けることにより、パワーアシストを行っていた。 Conventionally, as this type of sliding bearing used, a sliding sensor in an electric power steering or the like does not include a rotation sensor, and a motor for driving is, for example, a motor encoder shown in Patent Documents 1 and 2 Or by providing a VR resolver disclosed in Patent Document 3 outside the motor.
従来の滑り軸受は、以上のように構成されていたため、次のような課題が存在していた。
すなわち、滑り軸受の中には角度センシング機能を有していなかったため、滑り軸受の周辺又はモータ自体に大型のセンサを組み込まなければならず、滑り軸受の周辺の大型化及びモータの大型化となり、近年のように、小型軽量のモータが求められると、このような要望には応えることが困難であった。
Since the conventional sliding bearing is configured as described above, the following problems exist.
That is, since the slide bearing did not have an angle sensing function, a large sensor had to be incorporated in the periphery of the slide bearing or in the motor itself, and the periphery of the slide bearing and the motor became large. When a small and light motor is required as in recent years, it has been difficult to meet such a demand.
本発明による角度センサ一体型滑り軸受は、外輪の内側に内輪が設けられ、前記外輪と内輪が滑り面を介して相対回転するようにした滑り軸受を用い、前記滑り軸受にはレゾルバが内蔵して設けられている角度センサ一体型滑り軸受において、前記滑り軸受は樹脂で形成され、前記レゾルバは樹脂で一体成形されている構成であり、また、前記外輪にはステータ巻線を有するステータが設けられ、前記内輪には前記ステータに対応するロータが設けられている構成であり、また、前記外輪にはロータが設けられ、前記内輪には前記ロータに対応するステータが設けられている構成であり、また、前記外輪の前記樹脂よりなる樹脂外周が前記滑り軸受の取り付け面を形成している構成である。 An angle sensor-integrated slide bearing according to the present invention uses a slide bearing in which an inner ring is provided inside an outer ring, and the outer ring and the inner ring rotate relative to each other via a sliding surface. The slide bearing includes a resolver. in aNGLE sensor integrated type sliding bearings that provided Te, before SL sliding bearing is formed of a resin, the resolver is configured are integrally formed of plastic, also, the outer ring has a stator winding A stator is provided, the inner ring is provided with a rotor corresponding to the stator, the outer ring is provided with a rotor, and the inner ring is provided with a stator corresponding to the rotor. a configuration and a structure in which a resin outer periphery consisting of the resin before Kigairin forms a mounting surface of the sliding bearing.
本発明による角度センサ一体型滑り軸受は、以上のように構成されているため、次のような効果を得ることができる。
すなわち、滑り軸受内に角度センサであるレゾルバを内蔵することで、回転指示と角度検出の両方を実現することができ、センサを内蔵した上で大幅な小型化及び軽量化を達成することができる。
また、モータの部品点数の低減及びコストダウンが達成できる。
Since the angle sensor integrated slide bearing according to the present invention is configured as described above, the following effects can be obtained.
That is, by incorporating a resolver, which is an angle sensor, in the slide bearing, both rotation instructions and angle detection can be realized, and a significant reduction in size and weight can be achieved while incorporating the sensor. .
In addition, the number of motor parts can be reduced and the cost can be reduced.
本発明は、滑り軸受に角度センサを内蔵させることにより、電動パワーステアリング用モータ、発電機、スターターモータ、位置決め用モータ等の軸受の角度センサで回転検出し、小型化等を達成するようにした角度センサ一体型滑り軸受を提供することを目的とする。 In the present invention, by incorporating an angle sensor in the slide bearing, rotation detection is performed by an angle sensor of a bearing such as an electric power steering motor, a generator, a starter motor, or a positioning motor, thereby achieving downsizing or the like. An object of the present invention is to provide an angle sensor integrated slide bearing.
