Description

本発明は一種の爪形回転子対装置に係り、特に、一種の、相互に噛み合う二つの回転子の構造形態が同じであり、相互の共役噛み合い過程を十分に順調とすることができ、騒音及び機構疲労を発生せず、且つ十分にパラメータで偶数個の噛み合い爪数を提供できる、外形が同じ二つの回転子からなる爪形回転子対装置に関する。   The present invention relates to a kind of claw-shaped rotor pair device, and in particular, the structural form of a kind of two mutually meshing rotors is the same, the mutual conjugate meshing process can be made sufficiently smooth, and the noise Further, the present invention relates to a claw-shaped rotor pair device comprising two rotors having the same outer shape, which does not cause mechanical fatigue and can provide an even number of meshing claws with sufficient parameters.

周知の爪形回転子は、実際の需要の違いにより、二つの回転子上の爪部に、奇数爪或いは偶数爪の組合せ形式がある。ただし、どちらの形式の組合せであっても、爪形回転子の構造は基本的に、二つの、相互共役噛合の定義回転子と共役回転子を包含し、これらの二つの回転子上の爪部が、相互共役噛合回転することで、周期性循環の圧縮運動を提供する。周知の爪形回転子の構造に関しては、特許文献１乃至６を参照されたい。   The known claw-shaped rotor has a combination type of odd-numbered claws or even-numbered claws in the claw portions on the two rotors depending on the difference in actual demand. However, in either type of combination, the structure of the claw-shaped rotor basically includes two rotors that define the mutual conjugate mesh and a conjugate rotor, and the claws on these two rotors. The parts rotate in a mutually conjugate meshing manner to provide a compressive motion of periodic circulation. For the structure of the known claw-shaped rotor, see Patent Documents 1 to 6.

しかし、周知の爪形回転子には、改善すべき共通する欠点がある。すなわち、相互噛合の過程中に騒音と振動の現象を発生することである。その原因は、爪形回転子の二つの爪部は先端部曲線にあって不連続を形成し、このため、周期性循環の圧縮運動過程にあって、定義回転子と共役回転子は先端部曲線が不順調であるために、二つの爪部の相互噛合性が不良となり、圧縮運動過程で騒音と振動を発生するのであり、ひいては、不当な噛合が発生する摩擦と機構疲労により、使用寿命が短くなってしまう。   However, the known claw rotor has a common drawback to be improved. That is, noise and vibration are generated during the mutual meshing process. The reason is that the two claws of the claw-shaped rotor are in the tip curve and form a discontinuity, so in the compression motion process of periodic circulation, the defining rotor and the conjugate rotor are at the tip. Since the curve is not smooth, the mutual engagement of the two claws becomes poor, and noise and vibration are generated during the compression movement process.As a result, the service life is due to friction and mechanical fatigue that cause inappropriate engagement. Will be shorter.

最後に、それぞれ、定義回転子１００と共役回転子２００の単一爪部の先端部及び根部輪郭（すなわち第１爪部の断面外形１１０、２１０）を、交錯式に複製し回転させれば、偶数倍の同じ爪数と構造形態の定義回転子１００と共役回転子２００を取得できる。   Finally, if the tip and root contours of the single claw portion of the definition rotor 100 and the conjugate rotor 200 (that is, the cross-sectional outlines 110 and 210 of the first claw portion) are replicated and rotated, respectively, The definition rotator 100 and the conjugate rotator 200 having the same number of claws and structure forms that are even multiples can be acquired.

図１及び図２に示されるように、第１実施例の６爪の定義回転子１００と共役回転子２００は、同じ偶数個の爪部と同じ爪部断面外形を有し、製造上、該定義回転子１００及び共役回転子２００は同じ外径ｒ及びピッチ円半径ｒpを有し、且つ外径ｒはピッチ円半径ｒpよりも大きくなければならない。 As shown in FIGS. 1 and 2, the six-claw definition rotor 100 and the conjugate rotor 200 of the first embodiment have the same even number of claw parts and the same claw section cross-sectional outline, The definition rotor 100 and the conjugate rotor 200 have the same outer diameter r and pitch circle radius r p , and the outer diameter r must be larger than the pitch circle radius r p .
