Optimization Methods for Transmission Mode of Flying Shear Device with Crank Connecting Link for Slab Bands

文章以曲柄连杆板带飞剪装置传动系统为研究对象,求解曲柄连杆机构受力关系并计算飞剪齿轮箱在工作过程承受的剪切扭矩,定量讨论在单飞轮以及双飞轮两种模式下飞剪传动系统的功率流分配关系,进而量化在两种设计模式下飞剪齿轮箱的承载能力。工程实例表明:在大规格板带飞剪装置中,双飞轮模式可以减小单个飞轮质量的同时确保飞剪装置具有更高的可靠性。

In the paper, the transmission system of flying shear device with crank connecting link for slab bands is taken as the object of study. The stress relationship of crank and connecting rod mechanism is solved as well as the shear torque of gearbox for flying shears during working process is calculated. Moreover, the distribution relations of power flow for transmission system of flying shears with the modes of single flywheel and double flywheels are discussed quantificationally to quantify the carrying capacity of gearbox for flying shears with the two modes. The results of engineering examples indicate that the mass of single flywheel could be reduced and the reliability of flying shear device could be higher with double fly- wheel mode for large flying shear device for slab bands.
