【摘要】：Hy-Vo齿形链传动作为一种应用广泛的传动形式,具有传动平稳、噪声小、耐磨性强等众多优点。而双相传动Hy-Vo齿形链相比单相传动Hy-Vo齿形链,传动性能更加优良,能够显著降低Hy-Vo齿形链的波动量、振动噪声等。本论文基于国家自然科学基金“双相传动Hy-Vo齿形链系统的多元变异及其啮合机理研究”,以及吉林省科技计划项目“复相传动Hy-Vo齿形链系统关键技术研究”,分析了双相传动Hy-Vo齿形链的多元变异形式,进行了双相传动Hy-Vo齿形链的多元变异特性及其设计方法的研究。本论文基于Hy-Vo齿形链与链轮刚柔耦合传动的啮合原理,建立了基于心形孔的双相传动Hy-Vo齿形链-链轮-刀具的啮合设计体系,构建了基于心形孔的双相传动Hy-Vo齿形链传动系统及单相传动Hy-Vo齿形链传动系统的动力学模型,并对链板的主要设计参数:基准边心距和定位偏置角进行了变异设计,并分析其与齿形链传动系统波动量的谐应关系。仿真分析结果表明,无论基准边心距和定位偏置角参数值如何变化,其双相传动系统的波动量均明显小于单相传动系统的波动量。并且,与单相传动系统相比,双相传动时链板的角速度变化幅度小、频率低、瞬时传动比相对更加准确。此外,双相传动Hy-Vo齿形链的最优设计结果并不是单相传动Hy-Vo齿形链最优设计结果的简单叠加,而是不同设计参数相互影响相互作用的最优值,所以原有的单相传动的优化设计方法已不能满足双相传动的优化设计。其研究成果将为双相传动Hy-Vo齿形链的参数优化提供数据上的支持,并为Hy-Vo齿形链系统的多元变异耦合效应研究提供一定的科学依据。本论文提出了一种基于菱形孔的新型Hy-Vo齿形链,对链板菱形孔和销轴的形状进行描述与定义计算,并对基于菱形孔的双相传动Hy-Vo齿形链链板、链轮以及链板菱形孔和销轴的参数进行设计计算。通过建立基于菱形孔的双相传动Hy-Vo齿形链传动系统的动力学仿真模型,分析了其传动系统的运动轨迹、齿形链波动量、链板角速度、瞬时传动比及链节间张力。仿真分析结果表明,基于菱形孔的双相传动Hy-Vo齿形链运行平稳,且基于菱形孔的双相传动Hy-Vo齿形链的传动性能优于单相传动Hy-Vo齿形链的传动性能,进一步验证了其设计方法的可行性。由于基于菱形孔的双相传动Hy-Vo齿形链具有定位稳定、耐磨性高、易于润滑等特性,其研究成果将为基于菱形孔的双相传动Hy-Vo齿形链的深入研究与产品开发提供一定的理论依据。综上所述,本论文所研究的基于多元变异的双相传动Hy-Vo齿形链系统的设计方法,是对双相传动Hy-Vo齿形链优化设计方法的一种创新,同时,也进一步验证了对双相传动Hy-Vo齿形链研究的切实可行性与重要意义。
[Abstract]:As a widely used transmission form, Hy-Vo gear chain transmission has stable transmission and low noise. The wear resistance of dual-phase transmission Hy-Vo chain is better than that of single-phase transmission Hy-Vo chain, which can significantly reduce the fluctuation of Hy-Vo tooth chain. Vibration and noise, etc. This paper is based on the National Natural Science Foundation of China, "the study of multivariate variation and meshing mechanism of dual-phase transmission Hy-Vo tooth chain system". As well as Jilin province science and technology project "study on key technology of Hy-Vo tooth chain system of multiphase transmission", the multivariate variation form of dual phase transmission Hy-Vo tooth chain is analyzed. The multivariate variation characteristics of Hy-Vo tooth chain and its design method are studied. This paper is based on the meshing principle of Hy-Vo tooth chain and sprocket rigid flexible coupling transmission. The meshing design system of Hy-Vo tooth chain sprocket cutter based on heart-shaped hole is established. The dynamic model of dual-phase transmission Hy-Vo tooth chain transmission system and single-phase drive Hy-Vo tooth chain transmission system based on heart-shaped hole is constructed. The main design parameters of the chain plate, such as the reference center distance and the positioning bias angle, are designed, and the harmonic response relationship between them and the fluctuation of the gear chain transmission system is analyzed. The simulation results show that. No matter how the reference center distance and positioning bias angle parameter changes, the fluctuation of the two-phase transmission system is obviously smaller than that of the single-phase transmission system, and compared with the single-phase transmission system. The angle velocity of the chain plate is small, the frequency is low, and the instantaneous transmission ratio is more accurate. The optimal design result of two-phase transmission Hy-Vo tooth chain is not the simple superposition of the optimal design result of single-phase transmission Hy-Vo tooth chain, but the optimal value of the interaction between different design parameters. Therefore, the original single-phase transmission optimization design method can not meet the dual phase transmission optimization design. Its research results will provide data support for the parameter optimization of Hy-Vo tooth chain of dual-phase transmission. It provides a scientific basis for the study of multivariate variation coupling effect of Hy-Vo toothed chain system. In this paper, a new Hy-Vo toothed chain based on rhombic hole is proposed. The shape of diamond hole and pin shaft of chain plate is described and calculated, and the Hy-Vo tooth chain plate of dual phase transmission based on diamond hole is discussed. The parameters of sprocket and chain plate diamond hole and pin shaft are designed and calculated. The dynamic simulation model of Hy-Vo tooth chain transmission system based on diamond hole is established. The motion track of the transmission system, the fluctuation of the tooth chain, the angular velocity of the chain plate, the instantaneous transmission ratio and the interlink tension of the transmission system are analyzed. The simulation results show that. The Hy-Vo tooth chain of dual phase transmission based on diamond hole is stable, and the transmission performance of Hy-Vo tooth chain based on diamond hole is better than that of single-phase transmission Hy-Vo tooth chain. The feasibility of the design method is further verified. Because the dual-phase transmission Hy-Vo tooth chain based on diamond hole has the characteristics of stable positioning, high wear resistance, easy lubrication and so on. The research results will provide a certain theoretical basis for the further research and product development of dual-phase transmission Hy-Vo tooth chain based on diamond hole. In this paper, the design method of dual-phase transmission Hy-Vo tooth chain system based on multivariate variation is an innovation to the optimization design method of dual-phase transmission Hy-Vo tooth chain, at the same time. It also verifies the feasibility and significance of the research on the Hy-Vo tooth chain of dual phase transmission.
