既述の通り、本発明によれば、操作部材の質量とばね要素のばね剛性とを特定の 方法で互いに且つ振動プレートの周波数に、即ち干渉周波数に適合させるべきで ある。この適合化は、干渉周波数と、それぞれ操作部材の軸線に沿う並進運動お よび軸線まわりの回転運動並びにそれぞれ前記軸線に対し直角の二方向に沿い且 つ互い方向の並進運動およびこの二方向まわり且つ互い一方向の回転運動に関す る操作部材の特性周波数との間の関係が＞Ｖ’２となるように実施すべきである 。As described above, according to the present invention, the mass of the operating member and the spring stiffness of the spring element are set to a specific value. should be matched in a way to each other and to the frequency of the vibrating plate, i.e. to the interference frequency. be. This adaptation is based on the interference frequency and the translational movement along the axis of the actuating member, respectively. and rotational movement about an axis, respectively along two directions perpendicular to said axis and Regarding translational motion in mutual directions and rotational motion around these two directions and in one direction relative to each other. should be carried out so that the relationship between the characteristic frequency of the operating member and the characteristic frequency is > V’2. .
振動プレートの振動絶縁ハンドルに対する正しいばね剛性と質量を理論的に計算 することについて、第２図を参照しながら以下に説明する。第２図は、ハンドル のシャフト部材１０とばね１６を介してシャフト部材１０間に取付けた操作部材 １１を概略的に示す。第２図には、互いに直角な３つの座標軸が示されている。Theoretically calculate the correct spring stiffness and mass for the vibration isolation handle of the vibration plate This will be explained below with reference to FIG. Figure 2 shows the handle an operating member attached between the shaft member 10 and the shaft member 10 via the spring 16; 11 is schematically shown. In FIG. 2, three mutually perpendicular coordinate axes are shown.
即ち、操作部材１１と同軸のＹ方向と、互いに直角且つＹ方向に直角な２つの方 向２およびＸである。図面において、軸Ｘは紙面に対し直角であり、２つの矢印 ｙ、ｚの交差点を通って蔦びる。That is, the Y direction is coaxial with the operating member 11, and the two directions are perpendicular to each other and perpendicular to the Y direction. Direction 2 and X. In the drawing, axis X is perpendicular to the plane of the paper, and two arrows It rises through the intersection of y and z.
操作部材１１の支持については、振動絶縁の計算に際し各々の特定のケースで操 作部材の正確な位置を確立できるように６つの異なる振動方向を考慮しなければ ならない。これらの移動の３つは、軸Ｘ、Ｙ、Ｚ方向の並進運動である。その他 にこれらの各軸まわりの回転運動を考慮しなければならない。これに関し、αは Ｘ軸まわり、βはＹ軸まわり、γは２軸まわりの回転を示す。これらの並進およ び回転運動の各々には、本発明に関連する重要な特性周波数がある。シャフト部 分１（ＨＣ対する操作部材１１の絶縁を十分に満足なものとするためＫは、本発 明によれば、これらの特性周波数が干渉周波数（振動プレートによって発生され る振動の主周波数）よりかなり下回らなければならず、干渉周波数と各特性周波 数との関係が〉Ｖ−１であれば最良の絶縁が得られるということが判っている。The support of the actuating member 11 is determined in each specific case when calculating the vibration isolation. Six different vibration directions must be considered to be able to establish the exact position of the working part. No. Three of these movements are translations in the X, Y, and Z axes. others The rotational motion around each of these axes must be considered. In this regard, α is β represents rotation around the X axis, β represents rotation around the Y axis, and γ represents rotation around two axes. These translations and Each of the rotational and rotational motions has a characteristic frequency of interest that is relevant to the present invention. shaft part 1 (in order to ensure sufficient insulation of the operating member 11 against HC, K is According to Akira, these characteristic frequencies are called interference frequencies (generated by the vibrating plate). The interference frequency and each characteristic frequency must be considerably lower than the It has been found that the best insulation is obtained if the relationship is >V-1.
操作部材の吊持をいわゆる３対称支持であれば、特性周波数の計算はかなり簡単 化できる。従って、特性周波数は以下のよ５＆Ｃして計算される。Calculating the characteristic frequency is quite easy if the operating member is suspended in a so-called 3-symmetrical manner. can be converted into Therefore, the characteristic frequency is calculated by 5&C as follows.

ｆ、は２軸まわりの回転運動の特性周波数（Ｈ２）である。f is the characteristic frequency (H2) of rotational motion around two axes.
ｆβは２軸まわりの回転運動の特性周波数（Ｈ２）である。fβ is the characteristic frequency (H2) of rotational motion around two axes.
ｆａはＸ軸まわりの回転運動の特性周波数（Ｈ２）である。（この例では、ｆａ ＝０ であり、これはばねが理論的に全体に摩擦力を伴わないで、あるいは小さ な摩擦力を伴って固定されていることによる。）Ｍは操作部材の質量に２である 。fa is the characteristic frequency (H2) of rotational motion around the X axis. (In this example, fa = 0, which means that the spring theoretically has no or only small frictional force. This is due to the fact that it is fixed with a strong frictional force. ) M is 2 for the mass of the operating member. .
Ｋ２は２方向におけるばね要素の剛性Ｎ ／ ｍである。K2 is the stiffness of the spring element in two directions N/m.
豹はＹ方向におけるばね要素の剛性Ｎ ／ ｍである。The stiffness of the spring element in the Y direction is N/m.
ＫｘはＸ方向におけるはね要素の剛性Ｎ ／ ｍである。Kx is the stiffness N/m of the spring element in the X direction.
ＫβはＹ軸まわりのばね要素の捩り剛性Ｎ ／ ｍである。Kβ is the torsional stiffness N/m of the spring element around the Y axis.
ａ はばねの対称線までの質量中心距離であり、Ｙ軸に沿って測定したｍｏ ρは２対称軸に関する操作部材の回転半径ｍである。a is the center of mass distance to the spring symmetry line, and mo measured along the Y axis ρ is the radius of rotation m of the operating member with respect to the two symmetry axes.
ρ８はＸ対称軸に関する操作部材の回転半径ｍである。ρ8 is the rotation radius m of the operating member with respect to the X symmetry axis.
上述の特性周波数の各々が振動で生じる振動板の干渉周波数よりはるかに小さく 、しかも干渉周波数と操作部分の各特性周波数との関係が＞ｖ”２−であるよう に２つのばね１６のばね定数を適合させれば、非常に良好な振動絶縁が得られる 。ばね要素を砂時計または亜鈴の形状に設計し、ばね要素の偏倚を無くしたため 、ばね要素の寿命およびシャフト部材における操作部材の支持の寿命を非常に長 くする。従って、振動プレートを使用した際１、操作部材は残りの振動プレート に対して絶縁された非常に満足すべき振動となり、作業者にとっては機械が扱い 易く、また職業上の傷害の危険性が少くなる。機械を転回させたり、それ以外の 方法で取扱い作業者がかなり大きな力を部材１１に加えるいように、カップ状手 段１４に固着したゴムリング１５がカップ状手段１９の内側に係合する。このば ね撓み規制装置はさらにばね要素１６の損傷を招く恐れを伴うことなくハンドル により振動プレートを引き上げることを可能とする。Each of the characteristic frequencies mentioned above is much smaller than the interference frequency of the diaphragm caused by vibration. , and the relationship between the interference frequency and each characteristic frequency of the operating part is >v''2-. Very good vibration isolation is obtained by matching the spring constants of the two springs 16 to . The spring element is designed in the shape of an hourglass or a bell, eliminating the bias of the spring element. , the service life of the spring element and the support of the operating member in the shaft member is greatly increased. to save. Therefore, when using the vibrating plate 1, the operating member is the remaining vibrating plate. This results in very satisfactory vibrations that are isolated from easier and reduce the risk of occupational injury. Turning the machine or other A cupped hand is used to prevent the handler from applying a significant force to the member 11 during the process. A rubber ring 15 fixed to the step 14 engages inside the cup-shaped means 19. Konoba The spring deflection limiter also allows the handle to be removed without risking damage to the spring element 16. This makes it possible to pull up the vibrating plate.
