Description

本発明は、レゾルバと筒状ケースとの接続固定構造に関し、特に、筒状ケースをアルミダイキャストとし、筒状ケース用キー溝と輪状ステータ用キー溝間に形成された穴内に接着剤を注入することにより、レゾルバと筒状ケースとを簡単でかつ確実に固定するための新規な改良に関する。   The present invention relates to a connection and fixing structure between a resolver and a cylindrical case, and in particular, the cylindrical case is made of aluminum die cast, and an adhesive is injected into a hole formed between the cylindrical case key groove and the annular stator key groove. Thus, the present invention relates to a new improvement for easily and reliably fixing the resolver and the cylindrical case.

従来、用いられていたこの種のレゾルバと筒状ステータの接続固定構造としては、例えば、後述の特許文献１に示されているように、輪状ステータの外周面は凹凸のない円周状に形成されている。
そのため、レゾルバの輪状ステータと筒状ケースとの接続固定構造は、図４に示される構成が採用されていた。 Conventionally, as this type of resolver and cylindrical stator connection and fixing structure that has been used in the past, for example, as shown in Patent Document 1 described later, the outer peripheral surface of the ring-shaped stator is formed in a circumferential shape without irregularities. Has been.
Therefore, the structure shown in FIG. 4 has been adopted for the connection and fixing structure between the annular stator of the resolver and the cylindrical case.

すなわち、図４において符号１で示されるものは輪状ステータであり、この輪状ステータ１の内周面１ａからは所定角度間隔で内方へ向けて突出する複数の突出磁極２が形成され、前記各突出磁極２にはステータ巻線３が巻回されている。   That is, what is denoted by reference numeral 1 in FIG. 4 is a ring-shaped stator, and a plurality of projecting magnetic poles 2 projecting inward at predetermined angular intervals from the inner peripheral surface 1a of the ring-shaped stator 1 are formed. A stator winding 3 is wound around the protruding magnetic pole 2.

前記輪状ステータ１の外周面１ｂには筒状ケース４が嵌合されており、この筒状ケース４の内周面４ａは前記外周面１ｂに嵌合することにより、レゾルバの輪状ステータ１は筒状ケース４と一体状となり、この筒状ケース４を車輌等の所定位置に取付けることによって、レゾルバを所定位置に固定することができる。   A cylindrical case 4 is fitted to the outer peripheral surface 1b of the annular stator 1, and the inner peripheral surface 4a of the cylindrical case 4 is fitted to the outer peripheral surface 1b, so that the annular stator 1 of the resolver is cylindrical. The resolver can be fixed at a predetermined position by being integrated with the cylindrical case 4 and attaching the cylindrical case 4 to a predetermined position of a vehicle or the like.
