摘　　要：双离合器自动变速器(DCT--Dualclutch transmission)中,油泵通常由固定在双离合器上的油泵齿轮驱动。双离合器自动变速箱受载后,壳体、轴等发生的微观变形导致油泵驱动齿轮副发生啮合错位,这使得齿轮副接触斑点恶化和传递误差(TE)增大,并出现啸叫噪声。文中主要论述通过优化齿轮接触斑点等手段对某型DCT油泵驱动齿轮啸叫噪声消减的方法。The oil pump is usually driven by the gear which is mounted on dual-clutch in dual-clutch transmissions. When the transmission works under load, the deformation（in microscope） of housing and shafts may lead to pump gear misalignment, this will cause a worse contact pattern on tooth flank and big transmission error（TE）, meanwhile gear whine noise will occur. In this paper, gear micro-geometry re-design is used in a certain transmission to decrease whine noise.
