一、汽车变速箱齿轮图1 a)、b)分别为整体式和两体式汽车变速箱齿轮。本文主要介绍冷镦花键技术。花键为渐开线形式,为了便于与接合套结合,花键的一端起导向作用。图2表示齿轮特征,表1为各部分参数。在花键一端的导向部分 First, the gearbox car Figure 1 a), b), respectively, and two-piece car gearbox. This article describes the cold heading spline technology. Spline involute form, in order to facilitate the combination with the sleeve, one end of the spline plays a guiding role. Figure 2 shows the gear characteristics, Table 1 for each part of the parameters. The guide at one end of the spline
