8と9とは第2の振動質量体であって、材質はなるべく

、第1図には示してない。Note that the grip portion 3 and the rod body 20 are not shown in FIG. 1 due to the drawing space.
上記の構造を有する本発明装置の作用を説明すれば、つ
ぎのとおりである。The operation of the device of the present invention having the above structure will be explained as follows.
電動工具等の−・ウジフグから伝わる有害な原振動は連
結部2を介して振動受入れ部材1に伝えられ、あらまし
、そのままの振幅と周波数とをもって、第の振動質量体
4と5に伝えられる。Harmful original vibration transmitted from a power tool or the like is transmitted to the vibration receiving member 1 via the connecting portion 2, and is transmitted to the second vibrating mass bodies 4 and 5 with the same amplitude and frequency.
ただし、アーム状をした細口8,1bに振動系から見て
催かなからも弾性がある場合には、すでに、とσ所にお
いて、若干の振動減衰作用は得られるであろう。However, if the arm-shaped narrow openings 8 and 1b have elasticity even if viewed from the vibration system, some vibration damping effect will be obtained already at the and σ positions.
装置の中心線Cを中心として、左側の振動系は質量体4
よシバネ6を経て減衰されて第2の振動質量体8に伝わ
り、ふつうの手持工具の場合には径が5〜8mm程のも
のであるのを可とする棒体20の左伺痒分を介して第3
の振動質量体12に伝わり、質量体12はいちじるしく
減衰された姿態において振動をする。The vibration system on the left side is centered on the center line C of the device, and the mass body 4
The vibration is attenuated by the vibration spring 6 and transmitted to the second vibrating mass body 8, and the vibration on the left side of the rod body 20, which can have a diameter of about 5 to 8 mm in the case of an ordinary hand-held tool, is transmitted to the second vibrating mass body 8. 3rd through
is transmitted to the vibrating mass 12, which causes the mass 12 to vibrate in a significantly damped manner.
同様の振動の姿勢は、中心線Cよりも右側の振動系につ
いても起り、第1の振動質量体5よりバネγを経て減衰
されて第2の振動体9に伝わり、棒体20の右側半分を
介して第3の振動質量体13に伝わり、この質量体13
はいちじるしく減衰された姿態において振動する。A similar vibration attitude also occurs in the vibration system on the right side of the center line C, and is attenuated from the first vibrating mass body 5 via the spring γ and transmitted to the second vibrating body 9, and is transmitted to the right half of the rod body 20. is transmitted to the third vibrating mass body 13 via
vibrates in a significantly damped manner.
なお棒体20は第3の振動質量体16.17の間は図示
のように欠除するも、あるいは連続している形のものに
するも任意である。The rod 20 may be omitted between the third vibrating masses 16, 17 as shown, or may be continuous.
包含される各振動質量体およびバネの質量やバネ常数を
適宜に調節すると、中心線Cに合致するか、あるいは、
それにごく近いところの1点Aのところにおいて、振動
の節とも見なされる地点が存在することが確められるか
ら、少くとも、棒体20に清うところにおいて、左側お
よび右側の振動系、とくに第3の振動質量体12と13
は、振動時の大部分において、互いに反位相の振動をし
ているものとみることができる。If the masses and spring constants of each included vibrating mass body and spring are adjusted appropriately, it will match the center line C, or
Since it is confirmed that there is a point that can be considered as a node of vibration at a point A very close to that point, at least the left and right vibration systems, especially the 3 vibrating masses 12 and 13
can be seen as vibrating in antiphase with each other during most of the vibration.
したがって、第3の質量体12.13に対してのみ固着
されている握り部3は、他の諸点、とくに、その両端部
は、振動源とも、振動系の他の部分より物理的、機械的
に切り離されており、その中央部は振幅が理論的にはゼ
ロと見なしうる節Aと同様のあるいは、それに近い振動
をするのみであるから、したがって、いちじるしく少さ
な振動しか受けず、実験によると、1/10〜1//3
0程度までに、原振動を減衰させることができる。Therefore, the grip part 3, which is fixed only to the third mass body 12.13, is physically and mechanically more susceptible to vibration sources than other parts of the vibration system. The central part only vibrates as much as or close to node A, whose amplitude can be theoretically considered to be zero. and 1/10~1//3
The original vibration can be damped to about 0.
ただし、握り部3を手で提げることによって、棒体20
が第1振動質量体4,5の中心孔4a+5aの内壁面に
直接に接触すると、有害振動の棒体20への伝わりが一
部分直接的となるという不具合いはあるが、それでも振
動は元の1//10程度に減衰しうる。However, by holding the grip part 3 by hand, the rod 20
directly contacts the inner wall surfaces of the center holes 4a+5a of the first vibrating masses 4, 5, there is a problem that the harmful vibrations are partially transmitted directly to the rod 20, but the vibration still returns to the original 1 //It can be attenuated to about 10.
なお、本発明の装置において、中心線Cを中心とする左
右の振動系は、各質量及びバネ定数につき、左右が完全
な対称であるとする。In the apparatus of the present invention, it is assumed that the left and right vibration systems centered on the center line C are completely symmetrical with respect to each mass and spring constant.
きわめて簡単なものにした振動モデルについて説明した
ものであるけれども、振動源より連結部2を通じて入つ
てくる振動の如何によっては、左右非対称のものに出来
るのはいう迄もなく、そのような姿勢はいう迄もなく設
計事項に属することである。Although this is an explanation of a very simple vibration model, it goes without saying that depending on the degree of vibration that enters from the vibration source through the connecting part 2, it is possible to create a left-right asymmetrical posture. Needless to say, this is a matter of design.
なお、原振動は、振幅および周波数において、いろいろ
のものを含み、またその振動平面の向も多様である複雑
であるけれども、上述のように左右に割振用の振動系を
、正しくか、あるいは、あらまし対称的に構成しである
ので、実験の結果によると、そのような複雑振動である
にも拘わらず、きわめて効果的に割振効果を達成し、実
用上充分な程度において、本発明所期の目的を達成しう
るものであることが判明している。Although the original vibration is complex, including various amplitudes and frequencies, and the direction of the vibration plane is also diverse, it is important to understand whether the vibration system for left and right distribution as described above is correct or Since the structure is symmetrical in outline, experimental results show that despite such complex vibrations, the allocation effect is extremely effectively achieved, and the desired effect of the present invention is achieved to a practically sufficient degree. It has been found that the objective can be achieved.
なお、バネはゴムのようなもので代置しうる。Note that the spring can be replaced with something like rubber.
