Abstract The planar ball reducer is small in size and is simple in processing. However, the relative velocity between the wave generator and ball is large, which decreases the operation efficiency. In this work, a novel planar ball reducer based on a rolling bearing is proposed to eliminate the high relative velocity, and the equations of its tooth profile characteristics are deduced. The equations of the relative velocity and meshing efficiency between meshing pairs are also developed, and are used to investigate the relative velocity and meshing efficiency of the reducer. The results show that the relative velocity of the novel planar ball reducer is largely reduced and its meshing efficiency is more than two times greater than that of the classic reducer. Experiments verify the superiority of the proposed novel reducer and the correctness of the theoretical analysis.

一种新型平面球减速器的相对速度和啮合效率

摘要 平面滚珠减速器体积小，加工简单。然而，波发生器与球体之间的相对速度较大，降低了运行效率。在这项工作中，提出了一种基于滚动轴承的新型平面球减速器，以消除高相对速度，并推导出其齿廓特性方程。还建立了啮合副之间的相对速度和啮合效率方程，用于研究减速器的相对速度和啮合效率。结果表明，新型平面滚珠减速器的相对速度大大降低，啮合效率比经典减速器高两倍以上。
