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。In order to reduce the motion unevenness of the conveyor chain, a new kind of double - pitch silent chain is proposed and used in conveyor to replace the traditional double - pitch roller chain. The main design parameters of the chain plate is given, the double - pitch silent conveyor chain system and double pitch roller conveyor chain system of the virtual prototype model are created, and the simulation comparison experi- ment of the motion unevenness of this two systems are carried out. The analysis results show that, under the same condition, compared with double -pitch roller chain, the tension side lateral fluctuate value, unevenness of horizontal velocity and unevenness of driven sprocket angular velocity of double - pitch silent chain are respectively reduced 24. 18% , 45.61% and 23.13%. Therefore, it can be deduced that the double -pitch silent chain motion unevenness is smaller than double -pitch roller chain distinctly.
