The embodiment of the invention provides a hub reduction gear and a heavy dumper, and relates to the technical field of engineering machinery. The hub reduction gear comprises a rack, a first-stage planetary gear train and a second-stage planetary gear train, and the first-stage planetary gear train and the second-stage planetary gear train are both installed in the rack. The second-stage planetary gear train comprises a second-stage sun gear and a second-stage planet carrier, the second-stage sun gear is in transmission connection with the first-stage planetary gear train, a first spline is arranged at the end, away from the first-stage planetary gear train, of the second-stage sun gear, a spline housing is installed on the first spline, and the spline housing is rotatably supported on the second-stage planet carrier through a first bearing; and in this way, floating supporting of the second-stage sun gear is achieved, space can be provided for floating of the second-stage sun gear through matching of the first spline and the spline housing, the problem that the second-stage sun gear is abraded is solved, abrasion of the second-stage sun gear is transferred to the position of the spline housing, even if the spline housing is abraded, only the spline housing needs to be replaced, and the maintenance cost is low.

    本发明的实施例提供了一种轮边减速器及重型自卸车,涉及工程机械技术领域。轮边减速器包括机架、一级行星轮系和二级行星轮系,一级行星轮系和二级行星轮系均安装于机架内。二级行星轮系包括二级太阳轮和二级行星架,二级太阳轮与一级行星轮系传动连接,且二级太阳轮远离一级行星轮系的一端设置有第一花键,第一花键上安装有花键套,花键套通过第一轴承可转动地支承于二级行星架,如此实现二级太阳轮的浮动支撑,第一花键与花键套的配合即可为二级太阳轮的浮动提供空间,改善二级太阳轮出现磨损现象的问题,而且二级太阳轮的磨损转移至花键套处,即使花键套出现磨损问题,仅需更换花键套即可,维修成本低。
