【摘要】：为提高链式输送机的输送位置准确度,降低输送链条的运动不均匀性,提出了新型双节距齿形输送链的结构,给出了链板的主要设计参数,创建了双节距齿形输送链系统与双节距滚子输送链系统的虚拟样机模型,且针对两系统的运动不均匀性进行了仿真对比实验。结果表明,在相同条件下,与双节距滚子输送链相比,双节距齿形输送链的紧边链条横向波动量、水平速度不均匀性以及从动轮角速度不均匀性分别降低了24.18%、45.61%和23.13%。可见:双节距齿形输送链的运动不均匀性明显低于双节距滚子输送链。
[Abstract]:In order to improve the accuracy of conveying position of chain conveyor and reduce the movement inhomogeneity of conveying chain, the structure of a new type of double pitch tooth conveying chain is put forward, and the main design parameters of chain plate are given. The virtual prototype model of the double pitch tooth conveying chain system and the double pitch roller conveying chain system is established, and the simulation and contrast experiments on the motion inhomogeneity of the two systems are carried out. The results show that under the same conditions. Compared with the double pitch roller conveying chain, the lateral fluctuation, horizontal velocity inhomogeneity and angular velocity inhomogeneity of the tight edge chain are reduced by 24.18% respectively. 45.61% and 23.13. it can be seen that the motion inhomogeneity of the double pitch tooth conveying chain is obviously lower than that of the double pitch roller conveyor chain.
