摘要
针对某航空遥感器的同步传动机构要求:传动比大小为1∶1,二者转角方向相反,允许的转角误差为±36′,提出采用弹性体精密传动来满足这种要求。从弹性体的蠕动变形理论和传动部件机械加工精度出发,分析了弹性体的变形产生机理和传动件加工精度对传动机构精度的影响,对实际模型做有限元动力学分析。通过仿真分析,证明了设计的合理性。
An aircraft synchronic elastic transmission system＇s request： transmission ratio of 1∶1 with opposite direction,the most rotate angle error of ±36′ is permitted,the precision drive of elastomer could reach such a request.Based on the theory of the creep deformation and the machining precision of transmission parts,it conclude the influence of elastomer deformation and the machining for transmission parts,this paper use finite elements dynamic methods for predicting the accuracy of transmission parts,the result shows the design is reasonable.
