针对刮板输送机哑铃销在使用过程中频繁发生断裂的问题。在综合考虑了诸多学者研究成果的基础上,分别从结构、工艺两方面着手,对其进行改进设计,制成样件,并利用刮板输送机综合试验台对其进行加载试验,以强度和韧性作为评价参数,对其进行性能评价,强度满足要求,但韧性有待进一步提高。 For the scraper conveyor dumbbell pin frequent use in the process of fracture problems. On the basis of comprehensively considering the research results of many scholars, the authors respectively design and make samples from the aspects of structure and technology, and use the scraper conveyor comprehensive test bench to carry out the loading test. The intensity and Toughness as the evaluation parameters, its performance evaluation, strength to meet the requirements, but the toughness needs to be further improved.
