摘要：

针对液压式板坯结晶器驱动系统投资高昂、控制复杂、双缸同步性差等问题，提出了由空间非圆齿轮组成的两点连接、同步输出的板坯结晶器非正弦驱动系统。以新型空间非圆齿轮副为变速比传动机构，与偏心轴连杆一起合成结晶器的非正弦振动速度;建立了给定传动比下，波状面齿轮副的节曲线封闭条件和数学模型，并以此为基础，构建出振动波形具有匀速段特征的空间非圆齿轮节曲线;最后通过仿真计算，说明了根据给定非正弦波形设计非正弦驱动系统的流程。与其他形式的非正弦驱动系统相比，该系统不需伺服控制，且同步性能好，成本低，具有推广价值。

Abstract:

Due to the disadvantages of the vast investment, complicated control and weak synchronization of hydraulic driven device of slab molds, a new non-sinusoidal system comprised of spatial noncircular gears was presented with two point joint and synchronous output. Its transmission principle was given that the non-sinusoidal oscillation velocity of molds was composited by that of a pair of spatial noncircular gears and the eccentric shaft mechanism. The closed conditions and the mathematical model of pitch curves of the undulating face gear set were built under given transmission ratio, with non-sinusoidal wave constructed. Finally, the process for designing non-sinusoidal driven system under given wave function was illustrated through simulations. With the advantages of good synchronism and low cost over other driving styles, the new system has wide promotional values.

Key words: slab mold, non-sinusoidal vibration, spatial noncircular gear, synchronism
