通过试验研究了鼓形齿轮传动系统的静态传动误差和侧隙的冲击特性。研究了载荷、输入速度和冲击力指数系数对系统动态特性的影响。数值模拟表明，静态TE可以与间隙参数相结合。在低速条件下，动载荷主要与TE的高频分量有关，随着齿面精度的提高、齿形误差和粗糙度的改善，可以有效地抑制TE的高频分量。在高速条件下，TE轴频分量对共振区动载荷的影响占主导地位。参数减小，动载系数增大，特别是在共振区。当ε = 1.0时，系统中存在一个失接触冲击区，动态TE中轴频分量的幅值几乎相等，表明在无失接触时，系统的动态特性受负载和参数的影响很小。证明了非线性冲击模型是研究齿轮副拍击过程的充分条件。
The impact characteristics of a crowned gear transmission system are investigated with experimental static transmission error (TE) and backlash. The effects of load, input speed and impact force exponent coefficientnon the dynamic characteristic of system are investigated. The numerical simulations show that the static TE can be combined with a backlash parameter. Under low speed conditions, the dynamic load is mainly connected with the high frequency component of TE, which can be effectively suppressed with the increase of tooth surface accuracy and the improvement of tooth profile error and roughness. Under high speed conditions, the shaft frequency component of TE has a dominate influence on dynamic load in the resonance area. Parameternis decreasing and the dynamic load coefficient is increasing especially in the resonance area. Whennis 1.0, a loss contact impact area exists in the system and the amplitudes of shaft frequency component in dynamic TE are almost equal, which indicates that dynamic characteristics are little affected by load and parameternwhen there is no loss contact. It proves that the nonlinear impact model is sufficient to study the rattling process of gear pairs.
