The invention discloses a speed reduction device for a coupling planetary gear system of a mining dump truck, and belongs to the field of mining dump truck transmission. A hub is rotatably mounted onthe peripheral surface of a rack; the inner end of the rack is connected to a drive motor; the drive motor is connected to a half shaft through a drive sleeve; the outer end of the half shaft extendsout of the rack, and the outer end of the half shaft is connected to a duplex inner gear through a high-speed planetary carrier assembly and a low-speed planetary carrier assembly; the high-speed planetary carrier assembly and the low-speed planetary carrier assembly are assembled outside the rack; the inner end of the duplex inner gear is fixedly connected to the hub; and the outer end of the duplex inner gear is fixedly provided with an end cover assembly. The speed reduction device adopts a power dividing mode, is reasonable in load distribution, is small in low-speed solar wheel load, andis uniform in gear teeth stress; the output end of the drive motor and the input end of a wheel edge speed reducer are statically sealed by rubber, so that abrasion on sealing parts is reduced, and maintenance cycle is prolonged; and the output end is sealed by floating oil seal, and maze slots are formed in two end covers, so that external pollution is reduced.

    本发明公布一种矿用自卸车耦合行星轮系减速装置,属于矿用自卸车传动领域。机架外周面上转动安装有轮毂;机架的内端连接有驱动电机,驱动电机通过驱动套连接有半轴;半轴外端伸出机架,半轴外端通过高速级行星架装配、低速级行星架装配连接有双联内齿轮,高速级行星架装配、低速级行星架装配位于机架外侧;双联内齿轮内端与轮毂固定连接,双联内齿轮外端固定有端盖装配。本发明采用功率分流模式,载荷分配合理,低速级太阳轮承载小,齿轮轮齿受力均匀;驱动电机输出端与轮边减速器的输入端采用橡胶静密封,减小封件磨损,增加维保周期;输出端密封采用浮动油封,并且两端盖形成迷宫槽,减少外部污染。
