摘　　要：鼓型齿轮副的啮合力学特性对鼓型齿联轴器的承载能力和传动性能有重要影响。在传统鼓型齿轮副结构基础上,提出一种含过渡齿套的新型鼓型齿轮副;分析了鼓型齿轮副的啮合力学特性,探讨了不同倾角对其啮合力学特性的影响。结果表明,传统鼓型齿轮副的最大等效应力应变发生在内齿轴套上,新型鼓型齿轮副的最大等效应力应变发生在过渡齿套上;与传统齿轮副系统相比,新型齿轮副系统中的最大等效应力降低了32.12%、最大等效应变降低了21.4%,外齿轴套最大等效应力降低了15.75%;传统齿轮副的外齿轴套在齿根部位发生应力集中,新型齿轮副的外齿轴套在中间鼓肚位置发生应力集中;传统齿轮副中的最大等效应力和应变随轴间倾角的增大而增大,而新型齿轮副中外齿轴套的等效应力和应变部分转移到了过渡齿套上。因此,新型结构中的外齿轴套在较大倾角下仍能保持较低等效应力,可对成本高昂的外齿轴套起到有效保护作用。The meshing mechanical characteristics of crown gear pairs have an important impact on thebearing capacity and transmission performance of crown gear coupling. Based on the conventional crown gearpair structure, a late-model of crown gear pairs with transition gear sleeves is proposed, the meshing mechanicalcharacteristics of crown gear pair are analyzed, and the influence of different inclination angles on the meshingmechanical characteristics of crown gear pairs is discussed. The results show that the maximum equivalent stressand strain of the conventional crown gear pair occurs on the internal gear shaft sleeve, and the maximum equiva-lent stress and strain of the new crown gear pair occurs on the transition gear sleeve;compared with the conven-tional gear pair system, the maximum equivalent stress in the new gear pair system is reduced by 32.12%, andthe maximum equivalent strain is reduced by 21.4%. The stress concentration of the external gear shaft sleeve ofthe conventional gear pair occurs at the tooth root, and the stress concentration of the external gear shaft sleeveof the new gear pair occurs at the middle bulge position;compared with the conventional gear pair, the maxi-mum equivalent stress of the external gear sleeve in the new gear pair is reduced by 15.75%. With the increaseof the inclination angle between shafts, the maximum equivalent stress and strain in the conventional gear pairincrease, while the equivalent stress and strain of the external gear sleeve in the new gear pair is partially trans-ferred to the transition gear sleeve. Therefore, the external gear shaft sleeve in the new structure can still main-tain a lower equivalent stress under a larger inclination angle, which can effectively protect the expensive exter-nal gear shaft sleeve.
