Based on the ostwald - de waele equation, the leakage characteristics of power - law transmitted by helical gear pump are researched, and the leakage model of power - law in the clearence is founded, and - the velocity distributing and the leakage capacity are worked out by the boundary condition. the power loss of leakage is got through the clearence leakage capacity, and the friction power loss is attained by the velocity distributing. the mathematic calculation model
利用冪律流體本構方程，首次對聚合物流體在斜齒齒輪泵中的漏流特性進行了研究，建立冪律流體在間隙中的泄漏模型，利用邊界條件求出速度分佈及泄漏量；由間隙泄漏量得到漏流損失功率，由速度分佈得到流體摩擦功率損失，並得到間隙最優解的數值計算數學模型，同時給出實例及數值計算結果。
