摘要

为了研究误差对行星滚子螺杆性能的影响，选择对轴向间隙影响较大的齿形角误差作为研究对象，根据空间啮合原理建立了各零件的螺旋面方程。基于赫兹接触理论、弹塑性变形理论和变形协调原理，建立了考虑齿角误差的行星滚子螺杆载荷分布模型。利用ABAQUS软件对考虑齿形角误差前后的载荷分布进行了分析。结果表明:齿形角误差会影响行星滚子丝杠副的轴向间隙，增加整个系统负载分布的不均匀性，但不影响滚子两端负载分布的趋势;该研究为行星滚柱螺杆在工程实践中的应用提供了依据。

Load Analysis and Research of Planetary Roller Screw considering Tooth Angle error

in order to study the influence of error on the performance of planetary roller screw, the tooth profile angle error which has great influence on axial clearance is selected as the research object, and the spiral surface equation of each part is established according to the principle of spatial meshing. based on Hertz contact theory, elastic-plastic deformation theory and deformation coordination principle, the load distribution model of planetary roller screw considering tooth angle error is obtained. The load distribution before and after considering the tooth profile angle error is analyzed by ABAQUS. The results show that the tooth profile angle error will affect the axial clearance of the planetary roller screw pair and increase the non-uniformity of the load distribution of the whole system, but the trend of load distribution at both ends of the roller is not affected. This study provides a basis for the application of planetary roller screw in engineering practice.
