| 摘要: |
| 为了提高短筒柔轮谐波齿轮传动刚度,提出了一种柔轮和刚轮采用新齿形的短筒谐波传动的设计方法. 柔轮轮齿采用双圆弧齿廓,刚轮轮齿采用具有一定倾角的共轭齿廓,从而提高轮齿的啮合面积. 提出了采用慢走丝线切割加工柔轮和刚轮轮齿的加工工艺,分别试制了刚轮有倾斜轮齿、长径比各为1/4和1/2的两种50机型短筒柔轮谐波齿轮减速器样机,并进行了刚度测试实验. 结果表明,刚轮轮齿有倾角的新型短筒柔轮谐波传动与刚轮轮齿无倾角的短筒柔轮谐波传动相比,传动刚度可提高39%以上． |

| Abstract: |
| In order to improve the transmission stiffness of harmonic gear drive with short flexspline, a design of harmonic drive with new teeth profile is proposed. The teeth profiles of flexspline and circular spline are designed as double arc profile and its conjugate profile with certain axial inclination angle, respectively, so that the contact area between meshing teeth is improved. The WEDM-LS processes for teeth of short flexspline and circular spline are presented, and 50 prototype harmonic gear drives with tilt tooth circular spline and 1/4 and 1/2 length-diameter ratio are developed, respectively. The results of transmission stiffness experiments show that the transmission stiffness of the new designed harmonic gear driver is increased by 39% compared to that of the previous designed harmonic gear driver without tilt tooth. |
