Abstract:
This article includes an analysis of the possibility of using polymer materials for the production of harmonic drive. The use of additive methods greatly eases and accelerates the manufacturing of the flexspline. In the case of gears made of polymeric materials using rapid prototyping (RP) methods, the problem is often with their mechanical strength. In a harmonic drive, the wheel is uniquely exposed to damage, because during work, it deforms and is additionally loaded with torque. Therefore, numerical calculations were conducted using the finite element method (FEM) in the Abaqus program. As a result, information was obtained on the distribution of stresses in the flexspline and their maximum values. On this basis, it was possible to determine whether a flexspline made of specific polymers could be used in commercial harmonic drives or whether they were only adequate for the production of prototypes.
摘要:
本文包括对使用聚合物材料生产谐波驱动器的可能性的分析。添加方法的使用极大地简化和加速了柔性花键的制造。在使用快速成型(RP)方法由聚合物材料制成的齿轮的情况下,问题往往在于它们的机械强度。在谐波驱动中,车轮受到独特的损坏,因为在工作中,它变形,并额外加载扭矩。因此,在Abaqus程序中使用有限元方法(FEM)进行了数值计算。因此,获得了有关柔轮中应力分布及其最大值的信息。在此基础上,可以确定由特定聚合物制成的柔轮是否可以用于商业谐波驱动器,或者它们是否仅足以生产原型。
