The invention relates to the technical field of axle driving systems, in particular to a lubricating and sealing structure of an axle driving system. The lubricating and sealing structure comprises anaxle, wheels, a gear box, an axle suspension box and a traction motor, torque output by the traction motor is transmitted to the axle and the wheels through a driven gear and a driving gear in the gear box, and lubricating oil used for splash lubrication of the driven gear, the driving gear and a motor bearing is arranged at the bottom of the gear box. The lubricating and sealing structure has reliable static sealing and dynamic sealing structures, gear oil leakage can be effectively prevented, and therefore the amount of gear oil in a gear box is guaranteed, and the lubricating stability ofa gear and a bearing is guaranteed; and a wheel shaft driving device can effectively prevent lubricating oil in the gear box from entering a driving bearing chamber and prevent bearing grease in the bearing chamber from entering the gear box, mixed pollution of two lubricating media is avoided, and therefore the lubricating stability of the gear and the bearing is guaranteed.

    本发明涉及轮轴驱动系统的技术领域,尤其涉及一种轮轴驱动系统润滑密封结构。这种轮轴驱动系统润滑密封结构包括车轴、车轮、齿轮箱、抱轴箱和牵引电机,牵引电机输出的扭矩通过齿轮箱内从动齿轮和主动齿轮传递到车轴及车轮,齿轮箱底部装有用于从动齿轮、主动齿轮以及电机轴承进行飞溅润滑的润滑油,这种轮轴驱动系统润滑密封结构具有可靠的静密封及动密封结构,可以有效防止齿轮油渗漏,从而保证齿轮箱内的齿轮油量,确保了齿轮及轴承润滑的稳定性;该轮轴驱动装置既可以有效防止齿轮箱内的润滑油进入驱动轴承室,又可以防止轴承室的轴承脂进入齿轮箱内,避免了两种润滑介质的混合污染,从而保证了齿轮及轴承润滑的稳定性。
