Abstract

In order to investigate the influence of drive shaft offset on conveyor chain vibration in mesh belt dryer, the vibration of chain drive system is detected and analyzed by building a conveyor chain test platform, and at the same time, in order to better study the interaction between three factors, namely, rotational speed, center distance and offset, the response relationship of each factor on the transverse, longitudinal and lateral vibration displacements of the conveyor chain is analyzed by means of Box-Behnken test. It was found that when the test platform of conveyor chain was kept at the center distance of 660 mm, the level of triaxial vibration displacement increased with the increase of rotational speed; when the conveyor chain existed offset, the lateral vibration level of the test platform changed with the change of the tension level, i.e., the larger the average center distance of the two chains, the larger the amplitude of the lateral vibration displacement; when, in the rotational speed range from 27 rpm to 45 rpm, the rotational speed of 30 rpm When the rotational speed is 27 rpm to 45 rpm, the rotational speed is 30 rpm, the center distance is 659 mm, and the offset is 0 mm, the overall vibration amplitude of the conveyor chain test platform is the smallest, and the smoothness of the conveyor chain movement is the best. The study provides a reference for improving the smoothness of conveyor chain movement in mesh belt dryer.
