内齿轮泵
摘要：
提供一种内齿轮泵。该泵的多个外齿以及多个内齿的任一方的形状基于式(1)至(5)形成。r＝ro‑dr·cosθ式(1)；Px＝(ro‑dr)+1/4dr{1‑cos(2θ)}式(2)；Py＝1/4dr{‑2θ+sin(2θ)}式(3)；Qx＝Px‑r·cosθ式(4)；Qy＝Py+r·sinθ式(5)。
摘要（英）：

Provided is an internal gear pump. The shape of any one of a plurality of external teeth and a plurality of internal teeth of the pump is formed on the basis of formulae (1)-(5). Formula (1): r = ro - dr · cos ¸, Formula (2): Px = (ro - dr) + 1/4 dr {1 - cos (2¸)}, Formula (3): Py = 1/4 dr {-2¸ + sin (2¸)}, Formula (4): Qx = Px - r · cos ¸, Formula (5): Qy = Py + r · sin ¸.
