摘　　要：提出一种基于变齿厚齿轮的齿轮侧隙控制方法:在取得变齿厚齿轮副连续侧隙曲线规律基础上,根据主动轮的角位移来实时调整变齿厚齿轮主动轮与从动轮的相对位置关系进行侧隙控制;推导了具有偏心误差齿轮副的双向无负载传动误差及侧隙计算公式及其等效关系,在此基础上根据双向传动误差试验曲线获得了齿轮副连续侧隙曲线;在未消隙情况下,分析了不同负载幅值及不同负载频率的传动误差试验曲线,结果表明在交变负载下侧隙对齿轮副的动态传动误差有明显影响;在不同负载条件下,开展了基于变齿厚齿轮副的侧隙电控试验研究,对比其动态传动误差试验曲线,结果表明:电控侧隙控制后,因侧隙和脱啮导致的动态传动误差跳变或波动现象明显改善,动态传动误差明显减小,证明该侧隙控制方法有效。A backlash control method based on the variable tooth thickness gear pair(VTTGP) is presented. On the basis of the continuous backlash curve of VTTGP, the backlash compensation is carried out in real time according to the angular displacement of the driving gear by adjusting the relative position of driving and driven gear. The two-directions transmission error, backlash and their relationship of an involute gear pair with eccentricities are developed. On this basis, the continuous backlash curve of gear pair is obtained according to the experimental two-directions transmission error curve. The dynamic transmission error(DTE) curves of VTTGP under different loads with various amplitude and frequency are obtained by experimental method, and the results show that the backlash has a significant influence on the gear pair’s DTE. An experimental investigation on electrical control to backlash based on VTTGP is carried out under different varying load and the DTE is analyzed. The results show that the jump or fluctuation phenomenon of DTE is obviously improved after backlash control, which validates the electrical anti-backlash method.
