| description | [Technical Problem] Provided is an oil pump rotor that can embody the improvement of noiseless properties and volume effects. [Technical Solution] When a base circle (bi) of an inner rotor has a diameter (phibi), a first external rolling circle (Di) has a diameter (phiDi), a first internal rolling circle (di) has a diameter (phidi), a base circle (bo) of an outer rotor has a diameter (phibo), a second external rolling circle (Do) has a diameter (phiDo), a second external rolling circle (do) has a diameter (phido), and an amount of eccentricity between the inner rotor and an outer rotor is e, the following formulas are satisfied: phibi = n·(phiDi ＋ phidi) and phibo ＝ (n + 1)·(phiDo ＋ phido), and either phiDi ＋ phidi = 2e or phiDo ＋ phido = 2e, and furthermore, phiDo＞phiDi, and phidi＞phido. When a clearance between the inner rotor and the outer rotor is t, in a case of phiDi ＋ phidi = 2e, the following formula is satisfied: 0.3 @ ((phiDo ＋ phido) - (phiDi ＋ phidi ))·(n +1)/t @ 0.6. In the case of phiDo ＋ phido = 2e, the following formula is satisfied: 0.3 @ ((phiDo ＋ phido) - (phiDi ＋ phidi))·n/t @ 0.6.
Cette invention concerne un rotor de pompe à huile assurant l'amélioration des propriétés antibruit et des effets de volume. Si un cercle de base (bi) d'un rotor interne présente un diamètre (phibi), un premier cercle de roulement externe (Di) présente un diamètre (phiDi), un premier cercle de roulement interne (di) présente un diamètre (phidi), un cercle de base (bo) d'un rotor externe présente un diamètre (phibo), un second cercle de roulement externe (Do) présente un diamètre (phiDo), un second cercle de roulement interne (do) présente un diamètre (phido), et une excentricité entre le rotor interne et le rotor externe est égale à (e), alors : phibi = n·(phiDi ＋ phidi) et phibo ＝ (n + 1)·(phiDo ＋ phido). De plus, ou bien phiDi ＋ phidi = 2e ou bien phiDo ＋ phido = 2e, et phiDo＞phiDi, et phidi＞phido. Si un jeu entre le rotor interne et le rotor externe est égal à (t), et dans le cas où phiDi ＋ phidi = 2e, alors 0,3 @ ((phiDo ＋ phido) - (phiDi ＋ phidi))·(n +1)/t @ 0,6. Dans le cas où phiDo ＋ phido = 2e, alors 0,3 @ ((phiDo ＋ phido) - (phiDi ＋ phidi))·n/t @ 0,6. |
