The invention discloses a hub reduction gear, a terminal driving device, an assembling method and a mining dump truck. The hub reduction gear comprises a main shaft with an axial inner through hole, a hub, a gear ring assembly, a half shaft, a sun gear and a planet assembly. The hub is sleeved on the peripheral surface of the main shaft, and a bearing and a sealing assembly are arranged between the opposite peripheral surfaces of the hub and the main shaft; the gear ring assembly is sleeved on the main shaft in the hub, and the gear ring assembly and the main shaft are connected through a spline; the half shaft is inserted into the axial inner through hole of the main shaft; the sun gear and the half shaft are of a detachable assembly type structure, and outer splines of the sun gear and the half shaft are matched with inner splines of the sliding sleeve respectively. The planetary assembly is embedded in the gear ring assembly and connected with the hub, the outer portion of the planetary assembly is meshed with the gear ring, and the inner portion of the planetary assembly is meshed with the sun gear. The problems that a traditional terminal driving device is complex in structure, low in disassembly and assembly efficiency, poor in maintainability, high in manufacturing and using cost and the like are solved.

    本发明公开了一种轮边减速机、终端驱动装置、装配方法及矿用自卸车,轮边减速机包括具体轴向内通孔的主轴、轮毂、齿圈组件、半轴、太阳轮和行星组件;轮毂套装在所述主轴的外周面上,且在两者相向的周面之间安装有轴承和密封组件;齿圈组件套装在位于所述轮毂内部的主轴上,两者之间通过花键相连接;半轴穿插在所述主轴的轴向内通孔中;太阳轮与所述半轴之间为可拆装配式结构,且两者的外花键分别与滑套的内花键相配合;行星组件嵌入在所述齿圈组件内,并与轮毂相连,行星组件外部与齿圈相啮合,行星组件内部与太阳轮相啮合。本发明解决了传统终端驱动装置结构复杂、拆装效率低、维保性差、制造和使用成本高等问题。
