The invention discloses a wheel edge planet wheel shaft structure of a loader drive axle. The wheel edge planet wheel shaft structure comprises a wheel edge end cover and a planet wheel shaft, a planet wheel is installed on the planet wheel shaft through a roller bearing assembly, and the roller bearing assembly is limited through a check ring so that it can be guaranteed that the roller bearing assembly cannot get loose; the wheel edge end cover and the planet wheel shaft are in a split type, and the planet wheel shaft is in an independent flange type; a plurality of screw holes which are uniformly distributed are formed in the wheel edge end cover, and are fixed on the wheel edge end cover through screws; and an independent flange type planet wheel shaft is formed by forging a 20CrMnTi material and then carrying out carburizing and quenching treatment, so that the rigidity is improved. The problems that in the prior art, the manufacturing cost is high due to the fact that four standcolumns of the wheel edge end cover need to be forged and formed many times, and the failure rate is high due to stress concentration easily caused by roots of the four stand columns of the wheel edgeend cover are solved.

    本发明公开了一种装载机驱动桥轮边行星轮轴结构,它包括轮边端盖和行星轮轴;行星轮通过滚柱轴承组件安装在行星轮轴上,滚柱轴承组件通过挡圈限位,以确保滚柱轴承组件不松脱;所述轮边端盖和行星轮轴采用分体式,该行星轮轴为单独法兰型;其上设有多个均匀分布的螺钉孔,通过螺钉固定在轮边端盖上;所述单独法兰型行星轮轴采用20CrMnTi材料锻制后进行渗碳淬火处理而成,以提高刚性。本发明解决了现有技术中轮边端盖四个立柱需多次锻造成型导致制作成本高、轮边端盖四个立柱根部易引起应力集中造成故障率高的问题。
