SGZ-ⅢA型钻机变速分动箱改进设计

Design Improvement on Variable Transfer Case of GZ-ⅢA Drilling Rig

摘要:

利用转速图设计和分析钻机的传动系统，是一种比较简便和有效的辅助设计方法，能清晰而有条理地反映传动系统各传动副的关系。根据转速图分析了SGZ-ⅢA型钻机变速箱传动结构存在的问题，对变速箱的结构进行了改进设计，采用变速箱和分动箱的组合形式，使传动路线更合理。

Abstract:

It is convenient and effective to design and analyze the transmission system of drilling rig by speed diagram, so the relationship of transmission pairs could be distinctly reflected. The existing problems of gearbox structure of GZ-ⅢA drilling rig were analyzed according to the speed diagram, modification was made on gearbox, the combination of gearbox and transfer case were adopted, which made the transmission route more reasonable.
