SPROCKET GEROTOR PUMP

A sprocket gerotor pump includes an outer gerotor gear configured to rotate about a first axis. The outer gerotor gear includes an outer gear body including a plurality of internal gear teeth extending from the outer gear body toward the first axis. The sprocket gerotor pump includes an inner gerotor gear configured to rotate about a second axis. The inner gerotor gear includes an inner gear bodyand a plurality of external gear teeth extending from the inner gerotor gear away from the second axis. The external gear teeth mesh with the internal gear teeth. Rotating the outer gerotor gear causes rotation of the inner gerotor gear. The sprocket gerotor pump further includes a sprocket integrally coupled with the outer gerotor gear such that the sprocket and the outer gerotor gear collectively form a one-piece structure. The sprocket is driven by a chain. 一种链轮回转泵，包括被配置为绕第一轴线旋转的外回转齿轮。外回转齿轮包括外齿轮体，而外齿轮体包括从外齿轮体向第一轴线延伸的多个内齿轮齿。链轮回转泵包括被配置为绕第二轴线旋转的内回转齿轮。内回转齿轮包括内齿轮体及从内回转齿轮远离第二轴线向外延伸的多个外齿轮齿。外齿轮齿与内齿轮齿啮合。旋转外回转齿轮会带动内回转齿轮旋转。链轮
