この発明は、帯鋸盤における駆動装置に係わり更に詳し
くは、帯鋸刃とワークとの接触部で発生する強制振動現
象をか（乱し、振動の継続発生を阻止することで、騒音
の防止と、切削性能の向上と、工具の寿命の延長とを得
た装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drive device for a band saw machine, and more specifically, the present invention relates to a drive device for a band saw machine, and more specifically, a device for disturbing the forced vibration phenomenon that occurs at the contact portion between a band saw blade and a workpiece, and preventing the continuous generation of vibration. The present invention relates to a device that prevents noise, improves cutting performance, and extends tool life.
従来、帯鋸盤における帯鋸刃の駆動には、モータ回転ト
ルクを減速機を介して減速し、減速機出力トルクを駆動
ホイールに直接伝達することによつ℃、帯鋸刃を駆動す
る方式であった。Conventionally, the method of driving the band saw blade on a band saw machine was to reduce the rotational torque of the motor through a reducer, and then directly transmit the output torque of the reducer to the drive wheel. .
上記のような駆動方式の帯鋸盤で切削を続行すると、鋸
刃刃先が材料にくい込むことによって発生する強制振動
数、振動力によって鋸刃がまず加振される。When cutting continues with a band saw using the drive method described above, the saw blade is first vibrated by the forced vibration frequency and vibration force generated by the cutting edge of the saw blade digging into the material.
鋸刃は加振されることによって固有の振動モードで振動
を始める。When the saw blade is excited, it begins to vibrate in a unique vibration mode.
この振動モードは多数の実験結果から、縦振動モードが
支配的なものであることが解っている。It has been found from numerous experimental results that the longitudinal vibration mode is predominant.
この縦振動によって、工具と工作物間で切削方向での相
対振動が誘起され、しかもこの振動数は１０００ヘルツ
以上の高い振動数である。This longitudinal vibration induces relative vibration between the tool and the workpiece in the cutting direction, and this vibration frequency is as high as 1000 hertz or more.
要するに、鋸盤の両ホイール、鋸刃、の構造系全体が、
工具と工作物との間で発生する１０００ヘルツ以上の高
い周波数の振動モードを持つまでになり、騒音上と切削
性能上と、更に工具の寿命にまで悪い影響を与えている
のである。In short, the entire structural system of the saw wheels and saw blade is
Vibration modes with a high frequency of 1000 Hz or more are generated between the tool and the workpiece, which has a negative impact on noise, cutting performance, and even tool life.
実験によると、摩耗の進行した工具はど振動が生シやす
（、摩擦形びびりと呼ばれるがん高い音をともなってい
る。Experiments have shown that tools with advanced wear tend to vibrate (accompanied by a high-pitched sound called frictional chatter).
特に難削材（たとえばステンレススチール）を切削する
時には極め又不快な高音を発する為に、この音の発生を
阻止することが帯鋸盤での大きな課題となっている。Particularly when cutting difficult-to-cut materials (for example, stainless steel), an extremely unpleasant and high-pitched sound is emitted, so preventing the generation of this sound is a major challenge for band saws.
本発明は上記目的を達成するための機構を具備した帯鋸

。Since the device of this embodiment is configured as described above, the rotating member 63 driven by the worm gear 55 and the worm wheel 57 rotates around the hollow fixed shaft 15, and the cam follower 73 comes into contact with the cam TO. The cam TO drives the drive wheel 13, but the cam TO is separately equipped with a chain wheel 77, a sprocket 51, a chain wheel 53, a chain wheel 75, and a sprocket 6.
7, in order to rotate at a high rotational speed, the speed of the saw or the movement for cutting is not constant, and acceleration and deceleration are performed in short cycles, which disturbs the forced vibration phenomenon and causes the band saw to move at a high rotation speed. This prevents the generation of vibration noise caused by longitudinal vibration of the blade, improving cutting performance and extending tool life.
