Abstract

The transmission error of the gear transmission system is the main factor affecting its transmission performance. The expansion of special applications of elliptic gear transmission system and the improvement of transmission accuracy requirements put forward higher requirements for its transmission performance. Although many works have been presented to study the transmission error of cylindrical gear transmission system, a few works were focused on the transmission error of elliptic gears for the reason of the inconsistency of the tooth profile of the elliptic gear pair, the difficulty of establishing a transmission error model and obtaining the dynamic backlash. To overcome this problem, the theoretical model of the transmission error and backlash of the elliptic gear pair is proposed and established based on the meshing line incremental method. The ellipse gear transmission test-rig is built and the transmission test is carried out on it. Finally, the correctness of the theoretical model is verified. The results show that the dynamic backlash of the elliptic gear pair can be obtained through the bidirectional transmission error curve. The dynamic transmission error has a negative correlation with the speed and has a positive correlation with the load torque. The dynamic backlash shows an increasing relationship with the increase of speed and load torque. The research results of this article can provide a certain theoretical basis for the anti-backlash control of the elliptic gear transmission system and the improvement of transmission performance.

椭圆齿轮传动系统传动误差与动间隙的实验研究

齿轮传动系统的传动误差是影响其传动性能的主要因素。椭圆齿轮传动系统特殊应用领域的扩大和传动精度要求的提高对其传动性能提出了更高的要求。虽然对圆柱齿轮传动系统的传动误差进行了大量的研究，但由于椭圆齿轮副齿形不一致、传动误差模型的建立和动态齿隙的获取困难等原因，对椭圆齿轮传动误差的研究较少。针对这一问题，提出并建立了基于啮合线增量法的椭圆齿轮副传动误差与齿隙的理论模型。建立了椭圆齿轮传动试验台，并在其上进行了传动试验。最后，验证了理论模型的正确性。结果表明，通过双向传动误差曲线可以得到椭圆齿轮副的动态间隙。动态传动误差与转速呈负相关，与负载转矩呈正相关。动间隙随转速和负载转矩的增大而增大。本文的研究成果可为椭圆齿轮传动系统的抗间隙控制和传动性能的提高提供一定的理论依据。
