　　渐开线花键联结因其传递扭矩大、定心精度高等优点，在汽车行业得到广泛应用。为保证内、外花键同轴度，在汽车变速器中齿轮与轴多采用大径定心的花键过盈配合联结方式。在我国渐开线花键配合标准中没有此配合类别及其压装力计算方法。笔者试以光滑圆柱面过盈联结计算方法计算大径定心的渐开线花键配合压装力，为制定渐开线花键压装工艺提供依据。

The involute spline coupling is widely applied in automobile industry due to strong transmission torque and high centering accuracy.To assure the concentricity of internal and external splines, the coupling method of major diameter center-ing spline interference fit is mostly adopted between gears and shafts in a vehicle transmission.However, there are no fit cate-gories and calculating method of press fitting force in China′s involute spline fit standard.In this paper, the press fitting force of major diameter centering involute spline is calculated using the press coupling calculation method on a smooth cylindrical surface, thus the basis for establishing the press fitting process of involute spline is provided.
