某工程行走机械使用不到两个月,发现该机传递动力的主要零件之一主动盘失效(花键剥落),对失效原因进行了以下分析。主动盘受力分析主动盘形状见图1。主动盘的大端面与摩擦片相接触,通过花键将发动机动力输出。主动盘是传递动力的关键部件,它主要承受扭力及花键部位周期性的弯曲应力。材料要求及金相分析
A project using less than two months running machinery and found that the aircraft power transmission failure of one of the main disk failure (spline spalling), the failure of the reasons for the following analysis. Active disk force analysis of active disk shape shown in Figure 1. The major face of the drive plate is in contact with the friction plate and the engine power is output via splines. Drive plate is a key component of power transmission, it is mainly subjected to torsion and periodic bending stress spline parts. Material requirements and metallographic analysis
