特開平10−14169号公報Japanese Patent Laid-Open No. 10-14169

ところが、かかる従来のポンプ一体型電動機では、電動機の枠に形成した取付脚は電動機の下方に位置しているため、ポンプが大型であったり、ポンプに弁等を搭載したりして大重量の場合には、ポンプを支持する別の支持部材を必要としなければならず、部品点数が増加して構成が複雑になる問題点があった。   However, in such a conventional pump-integrated electric motor, since the mounting legs formed on the frame of the electric motor are located below the electric motor, the pump is large or a valve or the like is mounted on the pump. In this case, another support member for supporting the pump has to be required, which increases the number of parts and complicates the configuration.

本発明の課題は、電動機とポンプとを取付脚により支持して、ポンプを支持する別の支持部材を不要として部品点数の増加を抑制し、構成の簡素化を図り得るポンプ一体型電動機装置を提供するものである。   An object of the present invention is to provide a pump-integrated electric motor device that can support a motor and a pump with mounting legs, suppress an increase in the number of parts without using another support member that supports the pump, and can simplify the configuration. It is to provide.

かかる課題を達成すべく、本発明は次の手段をとった。即ち、
回転自在な出力軸を軸方向一端側に露呈する電動機と、軸方向一端側に露呈した入力軸の回転駆動で流体を吸入吐出するポンプと、出力軸で入力軸を回転駆動するよう電動機とポンプとを連結するブラケット部材と、被取付部材に固定する取付脚とを備え、取付脚はブラケット部材に着脱自在に有し、平面で相互に間隙を有して伸長する少なくとも2個の脚部を設け、各脚部の一端側を電動機の下方に位置すると共に、一端側と対向する他端側をポンプの下方に位置したことを特徴とするポンプ一体型電動機装置がそれである。
In order to achieve this problem, the present invention has taken the following measures. That is,
An electric motor that exposes a rotatable output shaft to one end in the axial direction, a pump that sucks and discharges fluid by rotating the input shaft exposed to one end in the axial direction, and an electric motor and a pump that rotationally drives the input shaft by the output shaft And a mounting leg fixed to the mounted member. The mounting leg is detachably attached to the bracket member, and has at least two legs extending in a plane with a gap therebetween. The pump-integrated electric motor apparatus is characterized in that one end side of each leg portion is located below the electric motor and the other end side opposite to the one end side is located below the pump.

以上詳述したように、請求項1に記載の発明は、被取付部材に固定する取付脚は電動機の下方とポンプの下方とにわたって位置しているため、電動機とポンプとを取付脚により支持できて、ポンプを支持する別の支持部材を不要として部品点数の増加を抑制でき、構成の簡素化を図ることができる。   As described above in detail, according to the first aspect of the present invention, since the mounting leg fixed to the mounted member is located below the motor and the pump, the motor and the pump can be supported by the mounting leg. Thus, another support member for supporting the pump is not required, and an increase in the number of parts can be suppressed, thereby simplifying the configuration.

また、取付脚はブラケット部材に有し、一端側を電動機の下方に位置すると共に、一端側と対向する他端側をポンプの下方に位置しているため、取付脚をブラケット部材とともに電動機およびポンプから取り外しできるから、取付脚による固定を他の固定手段に簡単に変更することもできる。さらに、取付脚はブラケット部材へ着脱自在に有しているため、ブラケット部材を電動機およびポンプから取り外すことなく、取付脚を取り外しできるから、取付脚による固定を一層簡単に変更することもできる。
Further, preparative Tsukeashi has the bracket member, for thereby positioning the one end side to the lower side of the electric motor, are located the other end facing the one end side to the lower side of the pump, the motor mounting leg with the bracket member and Since it can be removed from the pump, the fixing by the mounting leg can be easily changed to other fixing means. Furthermore, since the mounting leg is detachably attached to the bracket member, the mounting leg can be removed without removing the bracket member from the electric motor and the pump, so that the fixing by the mounting leg can be changed more easily.

次に、かかる構成の作動を説明する。
図1に示す状態で、電動機1を通電すると、出力軸4が回転して入力軸7を回転駆動し、ポンプ5はポンプ作動して流体を吸入吐出する。そして、電動機1を非通電にすると、出力軸4の回転が止まり、ポンプ5はポンプ作動を停止する。
Next, the operation of this configuration will be described.
When the electric motor 1 is energized in the state shown in FIG. 1, the output shaft 4 rotates and the input shaft 7 is driven to rotate, and the pump 5 operates to pump and discharge fluid. When the electric motor 1 is de-energized, the rotation of the output shaft 4 stops and the pump 5 stops the pump operation.

かかる作動において、被取付部材に固定する取付脚15は各脚部15B、15Cの一端側を電動機1の下方に位置すると共に、各脚部15B、15Cの他端側をポンプ5の下方に位置しているため、電動機1とポンプ5とを取付脚15により支持できて、ポンプ5を支持する別の支持部材を不要として部品点数の増加を抑制でき、構成の簡素化を図ることができる。   In such an operation, the mounting leg 15 fixed to the mounted member has one end of each leg 15B, 15C positioned below the motor 1 and the other end of each leg 15B, 15C positioned below the pump 5. Therefore, the electric motor 1 and the pump 5 can be supported by the mounting leg 15, an additional support member for supporting the pump 5 is not required, and an increase in the number of parts can be suppressed, and the configuration can be simplified.

また、取付脚15はブラケット部材10に有しているため、取付脚15をブラケット部材10とともに電動機1およびポンプ5から取り外しできるから、取付脚15による固定を他の固定手段に簡単に変更することもできる。さらに、取付脚15はブラケット部材10へ着脱自在に有しているため、ブラケット部材10を電動機1およびポンプ5から取り外すことなく、取付脚15を取り外しできるから、取付脚15による固定を一層簡単に変更することもできる。   Further, since the mounting leg 15 is provided on the bracket member 10, the mounting leg 15 can be detached from the electric motor 1 and the pump 5 together with the bracket member 10, so that the fixing by the mounting leg 15 can be easily changed to another fixing means. You can also. Further, since the mounting leg 15 is detachably attached to the bracket member 10, the mounting leg 15 can be removed without removing the bracket member 10 from the electric motor 1 and the pump 5. It can also be changed.

また、ブラケット部材10は、左側面11側に電動機1の枠2を取り付けて開口を閉塞すると共に出力軸4を回転自在に軸支する軸受け12を有しているため、従来の電動機における枠の端部に有したエンプラを兼用することができ、部品点数を削減して構成の簡素化を図ることができる。   Further, the bracket member 10 has a bearing 12 that attaches the frame 2 of the electric motor 1 to the left side surface 11 side, closes the opening, and rotatably supports the output shaft 4, so that the frame of the conventional electric motor is supported. The engineering plastic provided at the end can also be used, and the number of parts can be reduced to simplify the configuration.

作動は一実施形態と同様で、この作動において、被取付部材に固定する取付脚20は電動機2の下方に位置する脚部20Bの一端側端部をポンプ5の下方位置まで延在して設けているため、一実施形態と同様に、電動機1とポンプ5とを取付脚20により支持できて、ポンプ5を支持する別の支持部材を不要として部品点数の増加を抑制でき、構成の簡素化を図ることができる。   The operation is the same as that of the embodiment. In this operation, the mounting leg 20 fixed to the member to be mounted is provided by extending one end of the leg 20B located below the electric motor 2 to a position below the pump 5. Therefore, similarly to the embodiment, the electric motor 1 and the pump 5 can be supported by the mounting legs 20, an additional support member that supports the pump 5 is not required, and an increase in the number of parts can be suppressed, and the configuration is simplified.
