【摘要】 渐开线齿轮在啮合传动过程中含有明显的动载荷,在齿轮精度不变时,随着转速的增大,动载荷波动幅度增大,变速器冲击振动增加;因此,不能单靠增加轧制速度来提高轧制生产率。仿真结果与理论计算比较结果表明,二者数据比较吻合,证实了虚拟样机模型构建合理,仿真正确。更多还原

【Abstract】 The results showed that the meshing force of involute gears in the meshing process was obviously dynamic,and when gear accuracy remains unchanged,the fluctuation range of dynamic load and the vibration of transmission increased with the rise of the rotational velocity of gears,and that the rolling productivity couldn’t be increased by only the rise of rolling speed.Good coincidence between simulation results and theoretic calculated values proves that the virtual prototype is reliable and the simulation results are correct.更多还原
