Description
本発明は、電動機を固定する電動機固定ベースに関する。
The present invention relates to an electric motor fixing base for fixing an electric motor.
従来、電動機を固定する電動機固定ベースは、電動機からの振動でベース表面が振動する。ベース表面の面に対して垂直な方向に振動すると、振動が空気に伝播して音が発生する。特に電動機を電動機固定ベースに固定した状態で、固有振動数に近い加振力があると、共振して騒音となる。
Conventionally, an electric motor fixed base that fixes an electric motor vibrates the base surface due to vibration from the electric motor. When vibrating in a direction perpendicular to the surface of the base surface, the vibration propagates to the air and generates sound. In particular, when there is an excitation force close to the natural frequency in a state where the electric motor is fixed to the electric motor fixed base, it resonates and becomes noise.
電動機固定ベースの振動の集中箇所を特定して穴を設け、騒音の低減を図る手法が特許文献１に開示されている。
Patent Document 1 discloses a technique for identifying a concentrated portion of vibration in a motor-fixed base and providing holes to reduce noise.
しかしながら、特許文献１に開示される手法は、ベース表面の振動モードを、個々に解析又は実測して確認する必要があり、機種が変わると穴の位置も変更する必要がある。
However, in the method disclosed in Patent Document 1, the vibration mode of the base surface needs to be individually analyzed or measured and confirmed, and when the model changes, the position of the hole also needs to be changed.
そのため、特許文献１に開示される手法は、電動機固定ベースを複数の機種に対応させることはむずかしく、また、機種によって電動機固定ベースの剛性が変化してしまうという問題があった。
Therefore, the method disclosed in Patent Document 1 has a problem that it is difficult to make the motor fixed base compatible with a plurality of models, and the rigidity of the motor fixed base varies depending on the model.
本発明は、上記に鑑みてなされたものであって、騒音の発生を抑制して固定可能な電動機の機種が複数であり、固定する電動機の機種によって剛性が変動することを抑えた電動機固定ベースを得ることを目的とする。
The present invention has been made in view of the above, and there are a plurality of types of electric motors that can be fixed while suppressing generation of noise, and an electric motor fixing base that suppresses variation in rigidity depending on the type of electric motor to be fixed. The purpose is to obtain.
上述した課題を解決し、目的を達成するために、本発明は、２以上の機種の電動機のいずれかを択一的に固定可能な電動機固定ベースであって、電動機の複数の取付脚が固定される複数の取付脚固定部と、複数の取付脚固定部に囲まれた部分に設けられて、各機種の電動機を運転した際に振動が集中する複数の振動集中領域を含んだ領域を除去する穴と、を含むことを特徴とする。
In order to solve the above-described problems and achieve the object, the present invention is an electric motor fixing base that can selectively fix any of two or more types of electric motors, and a plurality of mounting legs of the electric motor are fixed. Removes the area including multiple vibration concentration areas where vibration is concentrated when operating various types of motors. And a hole to be formed.
本発明にかかる電動機固定ベースは、騒音の発生を抑制して固定可能な電動機の機種が複数であり、固定する電動機の機種によって剛性が変動することを抑えることができるという効果を奏する。
The electric motor fixing base according to the present invention has an effect that there are a plurality of electric motor models that can be fixed while suppressing the generation of noise, and it is possible to suppress variation in rigidity depending on the electric motor model to be fixed.
以下に、本発明の実施の形態にかかる電動機固定ベースを図面に基づいて詳細に説明する。なお、この実施の形態によりこの発明が限定されるものではない。
Hereinafter, an electric motor fixing base according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.
実施の形態．
図１及び図２を用いて本発明の実施の形態にかかる電動機固定ベースの構造を説明する。図１は、本発明の実施の形態にかかる電動機固定ベースに電動機を固定した状態を示す正面図である。図２は、実施の形態にかかる電動機固定ベースに電動機を固定した状態を示す下面図である。電動機固定ベース１０には、下部に取付脚２が形成された電動機１がボルト２０によって固定されている。電動機固定ベース１０には、電動機１とは異なる機種の電動機を固定することも可能である。すなわち、電動機固定ベース１０は、２以上の機種の電動機のいずれかを択一的に固定可能である。 Embodiment.
The structure of the motor fixing base according to the embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a front view showing a state in which an electric motor is fixed to an electric motor fixing base according to an embodiment of the present invention. FIG. 2 is a bottom view showing a state in which the electric motor is fixed to the electric motor fixing base according to the embodiment. Anelectric motor 1 having a mounting leg 2 formed in the lower portion is fixed to the electric motor fixing base 10 by bolts 20. It is also possible to fix an electric motor of a different model from the electric motor 1 to the electric motor fixing base 10. That is, the motor fixing base 10 can alternatively fix any of two or more types of motors.
図１及び図２を用いて本発明の実施の形態にかかる電動機固定ベースの構造を説明する。図１は、本発明の実施の形態にかかる電動機固定ベースに電動機を固定した状態を示す正面図である。図２は、実施の形態にかかる電動機固定ベースに電動機を固定した状態を示す下面図である。電動機固定ベース１０には、下部に取付脚２が形成された電動機１がボルト２０によって固定されている。電動機固定ベース１０には、電動機１とは異なる機種の電動機を固定することも可能である。すなわち、電動機固定ベース１０は、２以上の機種の電動機のいずれかを択一的に固定可能である。 Embodiment.
The structure of the motor fixing base according to the embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a front view showing a state in which an electric motor is fixed to an electric motor fixing base according to an embodiment of the present invention. FIG. 2 is a bottom view showing a state in which the electric motor is fixed to the electric motor fixing base according to the embodiment. An
電動機固定ベース１０は、取付脚２と接する複数の取付脚固定部３，３を有し、取付脚固定部３，３に囲まれた領域の中央部には円形の穴１１が形成されている。取付脚固定部３，３の中央部に穴１１を設けることにより、穴１１による電動機固定ベース１０の剛性の低下を小さく抑えることができる。実施の形態では、ボルト２０が配置された位置を四つ角の頂点とする矩形の中心Ｃと、穴１１の中心Ｏとが一致している。穴１１は、電動機１の回転軸１５を対称軸として線対称に配置されている。
The motor fixing base 10 has a plurality of mounting leg fixing portions 3 and 3 that are in contact with the mounting leg 2, and a circular hole 11 is formed at the center of the region surrounded by the mounting leg fixing portions 3 and 3. . By providing the hole 11 in the central part of the mounting leg fixing parts 3, 3, it is possible to suppress a decrease in rigidity of the motor fixing base 10 due to the hole 11. In the embodiment, the center C of the rectangle whose four corners are the positions where the bolts 20 are arranged coincides with the center O of the hole 11. The holes 11 are arranged in line symmetry with the rotation axis 15 of the electric motor 1 as the axis of symmetry.
図３を用いて、実施の形態１にかかる電動機固定ベースが備える穴の特性を説明する。穴１１は、取付脚固定部３に固定された各機種の電動機１を運転した際に振動が集中する複数の振動集中領域を含んでいる。図３は、実施の形態にかかる電動機固定ベースの穴の特性を示す図である。図３は、電動機固定ベース１０に機種Ａ、機種Ｂ及び機種Ｃのうちのいずれかの電動機１が固定される場合を例示している。機種Ａの電動機１を電動機固定ベース１０に固定して運転すると、振動集中領域１２に振動が集中する。機種Ｂの電動機１を電動機固定ベース１０に固定して運転すると、振動集中領域１３に振動が集中する。機種Ｃの電動機１を電動機固定ベース１０に固定して運転すると、振動集中領域１４に振動が集中する。
Referring to FIG. 3, the characteristics of the holes provided in the motor fixing base according to the first embodiment will be described. The hole 11 includes a plurality of vibration concentration areas where vibration concentrates when each type of electric motor 1 fixed to the mounting leg fixing portion 3 is operated. FIG. 3 is a diagram illustrating characteristics of holes in the motor fixing base according to the embodiment. FIG. 3 illustrates a case where any one of the model A, the model B, and the model C is fixed to the motor fixing base 10. When the electric motor 1 of model A is fixed to the electric motor fixed base 10 and operated, vibration concentrates on the vibration concentration region 12. When the electric motor 1 of model B is fixed to the electric motor fixed base 10 and operated, vibration concentrates in the vibration concentration region 13. When the electric motor 1 of model C is fixed to the electric motor fixed base 10 and operated, vibration concentrates on the vibration concentration region 14.
穴１１は、振動集中領域１２，１３，１４を含む領域を除去するように形成されているため、機種Ａ、機種Ｂ及び機種Ｃのいずれを電動機１に用いても、電動機固定ベース１０には、振動が集中する領域は存在しない。このように、穴１１は、取付脚固定部３，３に固定された各機種の電動機１を運転した際に振動が集中する複数の振動集中領域１２，１３，１４を含む領域を除去しているため、電動機固定ベース１０は、電動機１の複数の機種に対応可能であり、共通化を図ることができる。
Since the hole 11 is formed so as to remove the region including the vibration concentration regions 12, 13, and 14, no matter which model A, model B, or model C is used for the motor 1, There is no region where vibration is concentrated. In this way, the hole 11 removes a region including a plurality of vibration concentration regions 12, 13, and 14 where vibrations concentrate when the electric motor 1 of each model fixed to the mounting leg fixing portions 3 and 3 is operated. Therefore, the motor fixing base 10 can correspond to a plurality of models of the motor 1 and can be shared.
電動機固定ベース１０は、取付脚固定部３，３に固定された各機種の電動機１を運転した際に振動が集中する複数の振動集中領域１２，１３，１４を含む領域を除去する穴１１が形成されているため、空気に振動を伝える膜状の部分の一部が除去されることとなり、騒音の発生を抑制できる。
The motor fixing base 10 has a hole 11 for removing a region including a plurality of vibration concentration regions 12, 13, and 14 where vibration is concentrated when each type of motor 1 fixed to the mounting leg fixing portions 3 and 3 is operated. Since it is formed, a part of the film-like portion that transmits vibration to the air is removed, and the generation of noise can be suppressed.
また、電動機固定ベース１０は、取付脚固定部３，３に囲まれた部分に穴１１を設けるのみであるため、固定する電動機１の機種によらず剛性は一定である。したがって、電動機固定ベース１０は、騒音の発生を抑制して固定可能な電動機の機種が複数である。
Moreover, since the motor fixing base 10 is only provided with the hole 11 in the portion surrounded by the mounting leg fixing portions 3 and 3, the rigidity is constant regardless of the model of the motor 1 to be fixed. Therefore, the motor fixing base 10 has a plurality of types of motors that can be fixed while suppressing the generation of noise.
上記の説明においては、穴１１は円形であるとしたが、穴１１の形状は円形でなくてもよく、楕円形又は多角形であってもよい。また、取付脚固定部３，３に囲まれた領域の中央部に穴１１が形成されているとしたが、穴１１の位置は取付脚固定部３，３に囲まれた領域の中央部でなくてもよい。さらに、穴１１の数を２以上としてもよい。
In the above description, the hole 11 is circular, but the shape of the hole 11 may not be circular, and may be elliptical or polygonal. In addition, although the hole 11 is formed in the central portion of the region surrounded by the mounting leg fixing portions 3, 3, the position of the hole 11 is the central portion of the region surrounded by the mounting leg fixing portions 3, 3. It does not have to be. Further, the number of holes 11 may be two or more.
以上の実施の形態に示した構成は、本発明の内容の一例を示すものであり、別の公知の技術と組み合わせることも可能であるし、本発明の要旨を逸脱しない範囲で、構成の一部を省略、変更することも可能である。
The configuration described in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and can be combined with other configurations without departing from the gist of the present invention. It is also possible to omit or change the part.
