摘　　要：链轮是重型刮板输送机链轮轴组的关键件和易损件,因现有重型刮板输送机链轮轴组的整体式结构限制,链轮不能在井下直接完成更换,维修成本高,维修效率低。为此在保证强度和互换性的前提下对现有整体式链轮轴组进行了分体式改造,使链轮能够直接在井下完成更换;同时,对改造后的分体式链轮轴组进行了快速拆装装置设计和快速拆装工艺设计,以保证装配质量,提高维修效率;制作了分体式链轮轴组样机,使用快速拆装装置按照快速拆装工艺完成了性能试验。试验表明,分体式链轮轴组在保证强度和互换性的条件下,可以实现链轮在井下的直接更换,可有效降低维修成本,减少人工作业量;快速拆装装置和快速拆装工艺的使用有效提高了链轮的更换效率。链轮轴组的分体式改造方法和快速拆装装置及工艺的研究具有显著的实用价值和工程意义。Sprocket is a key and vulnerable component of the heavy-duty scraper conveyor sprocket shaft group.Due to the limitations of the overall structure of the existing heavy-duty scraper conveyor sprocket shaft group,the sprocket cannot be directly replaced underground,resulting in high maintenance costs and low maintenance efficiency.To this end,while ensuring strength and interchangeability,the existing integral sprocket shaft group has undergone a split transformation,allowing the sprocket to be directly replaced underground;at the same time,a rapid disassembly and assembly device design and a rapid disassembly and assembly process design were carried out on the modified split sprocket shaft group to ensure assembly quality and improve maintenance efficiency;a prototype of a split type sprocket shaft group was produced,and performance tests were completed using a rapid disassembly and assembly device according to the rapid disassembly and assembly process.Experiments have shown that the split type sprocket shaft group can achieve direct replacement of the sprocket underground under the conditions of ensuring strength and interchangeability,effectively reducing maintenance costs and reducing manual work volume;the use of rapid disassembly and assembly devices and processes effectively improves the efficiency of sprocket replacement.The research on the split transformation method,rapid disassembly and assembly device,and process of the sprocket shaft group has significant practical value and engineering significance.
