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.
