摘　　要：针对起重机平行轴斜齿轮副组成的减速器体积大、功重比小等缺点,设计了摆线针轮传动减速器。摆线针轮传动具有传动比大、刚性高、体积小、功重比高等优点。为分析减速器摆线轮与针齿接触力、同时接触齿数等动力学特性,建立修形摆线轮齿廓方程,在多体动力学软件中建立摆线针轮传动动力学模型,并进行动力学仿真分析。研究发现,同一修形方式下,齿顶齿根设计间隙越大,同时接触齿数越少,摆线轮与针齿接触力越大。In view of the shortcomings of the reducer composed of parallel-shaft helical gear pairs for cranes,such as large size and low power to weight ratio,a cycloidal-pin-annulus trans mission reducer is designed.The cycloidal pin-annulus transmission has the advantages of large transmission ratio,high rigidity,small size and high power to weight ratio.To ana lyze the dynamic characteristics such as the contact force and the number of simultaneous contact teeth between the cycloidalannulus and the pin teeth,an equation of modified cycloidal annulus tooth profile is established,a dynamic model of the cycloidal pin annulus transmission is constructed in the multi-body dynamics software,and dynamic simulation analysis is carried out.It is found that,under the same modification mode,the larger the designed gap between the tooth top and the tooth root and the fewer the contact teeth,the greater the contact force between the cycloi dal annulus and the pin teeth.The relevant research can provide a theoretical reference for the design of cycloidal-pin-annulus trans mission for cranes.
