【摘要】：利用同步带传动爬齿机理,建立了传动误差数学模型,揭示了同步带传动误差为带轮一个节距转角的函数。基于Recur Dyn建立同步带虚拟样机动态传动仿真模型,通过数据采集及数值分析得出啮合点处带的爬齿轨迹-阿基米德螺线,仿真结果与试验结果一致,验证了仿真分析的准确性。并对新齿廓与L型梯形齿同步带进行传动精度对比研究,结果表明新齿廓同步带传动误差(Δθ=0.932 mrad)小于L型梯形齿同步带(Δθ=1.615 mrad),说明新齿廓同步带抗爬齿能力强于L型梯形齿,新齿廓同步带齿形设计更合理。
[Abstract]:The mathematical model of transmission error is established by using the mechanism of synchronous belt transmission. The function that the transmission error of synchronous belt is a pitch angle of belt wheel is revealed. The dynamic transmission simulation model of virtual prototype of synchronous belt is established based on Recur Dyn. Through data acquisition and numerical analysis, the trajectory of climbing teeth in the meshing point is obtained, and the simulation results are in agreement with the experimental results. The accuracy of the simulation analysis is verified, and the transmission accuracy of the new tooth profile is compared with that of the L-type trapezoidal synchronous belt. The results show that the transmission error of the new tooth profile synchronous belt (螖胃 ~ (0.932) mrad) is smaller than that of the L-type trapezoidal synchronous belt (螖胃 ~ (1.615) mrad). It shows that the new tooth profile synchronous belt has better anti-climbing ability than L type trapezoid tooth, and the new tooth profile synchronous belt tooth shape design is more reasonable.
