摘　　要：船舶在波浪中航行时,船体会发生中拱及中垂弯曲变形.这会导致沿船的纵向布置的传动齿轮轴轴承支座中心距缩减,轴承运行负荷增加,使用寿命降低,尤其是轴系被固定在上甲板或船底时,这种影响会达到不容忽视的地步.文章对纵向布置斜齿圆柱齿轮轴轴承间距缩减产生的附加径向力进行了计算,对该附加径向力作用下的轴承受力情况进行分析,并提出船用斜齿轮圆锥滚子轴承选用公式.A ship navigating in waves will develop hogging and sagging bending deformations of its body. The bending deformations may make the center distance of bearings of a gearing arranged along the ship longitudinal direction reduce, the load of the bearings increase, and the life of the bearings reduce. Especially when the shafting is fixed on the upper deck or the bottom, the effect will achieve unignorable level. This article calculates the additional radial pressure produced due to the reduction of the bearing center distance, analyzes forces acted on the bearings under this condition, and brings forward a group of equations for the selection of taper roller bearings for marine helical gears.
