在重型工业、国防、航空、航天领域有着广泛应用的谐波行星传动,具有结构紧凑、体积小、传动比大、承载能力高等诸多优点,然其存在柔轮易疲劳、扭转刚度低、材料昂贵等问题,本文提出以从动杆替代柔轮,实现谐波行星传动的创新设计,简述其基本工作原理、波轮齿廓理论廓线方程,对所研制样机从动杆滚子中心点及质心进行运动分析,得出位移、速度、加速度、加加速度等曲线图,可全面反映从动件运动特性及变化规律,对于进一步研究机构的动力参数、效率曲线与动态仿真提供依据。
In the field of heavy industry, national defense, aviation and aerospace, it has many advantages such as compact structure, small size, large transmission ratio and high carrying capacity. However, it has the advantages of soft wheel fatigue, low torsional rigidity and expensive materials In this paper, we propose an innovative design that replaces the flexspline with the driven rod and achieves the harmonic planetary transmission. The basic working principle, the theoretical profile equation of the pulsar profile are briefly described. The centroid motion analysis shows the displacement, velocity, acceleration, jerk and other curves can fully reflect the follower movement characteristics and changes in law, to further study the mechanism of dynamic parameters, efficiency curves and dynamic simulation provide the basis.
