摘　　要：推土机中央传动伞齿轮有悬臂式和双跨式两种安装方式,安装方式不同,伞齿轮处轴承所承受的载荷大小将不同。介绍两种安装方式下,轴承径向和轴向载荷的计算公式,以及轴承使用寿命校核的方法。通过计算分析,得出伞齿轮安装方式对轴承载荷具有重要影响的结论。How a load acts on bevel gear at a bulldozer's central transmission.These bevel gears are mounted in an overhang way or twin-span way,which would result in different amount of load taking capability of bearings there.The text further introduces formulas to compute the radial and axial loads on the bearings,as well as to check work life of the bearings as concerning the 2 ways of mounting.Finally,we thru computation and analyses have made a conclusion that the manner in which to mount the bevel gear does affect greatly the load on the bearing.
