渐开线花键是齿轮箱传递转矩的重要零件,通常花键联接仅用于传递转矩,但在某些场合,花键还要承受部分径向载荷、弯矩或者轴向载荷,这些载荷可导致内外花键齿面发生相对移动,从而引起齿面磨损。笔者针对花键跑合及发生疲劳磨损时产生的磨损量,研究花键联接发生滑动磨损和疲劳磨损的机理,并且给出花了键磨损寿命的计算方法。
Involute splines are an important part of the gearbox to transmit torque. Spline joints are usually used to transmit torque only, but in some cases the splines are also subject to partial radial loads, bending moments or axial loads Loads can cause relative movement of the internal and external spline tooth flanks, causing wear on the flanks. The author studies the mechanism of sliding wear and fatigue wear of spline joint in spline running-in and fatigue wear, and gives the calculation method of key wear life.
