LYDZC交叉滚子转盘轴承概述:
LYDZC交叉滚子转盘轴承可以同时承受轴向载荷、倾覆力矩和径向载荷。交叉滚子转盘轴承的结构和应用与四点接触球转盘轴承基本相同,只是滚动体由钢球变为滚子,滚动体与内外圈的接触由点接触变为线接触。故承载能力增加,但磨损和摩擦力矩将增大。
LYDZC交叉滚子轴承结构及特性:
LYDZC交叉滚子转盘轴承主要由内圈、外圈、单排交叉放置的滚子、保持架(隔离块)、密封装置等零件组成。
LYDZC交叉滚子转盘轴承的圆柱滚子(轴线)在滚道上呈十字交叉分布,圆柱滚子的长径比小于1,滚子在运动时存在轻微的滑动。
通过调整滚子交叉数量和接触角,可以应对各种工况条件下产生的不同轴向力、倾覆力矩和径向力组合。
LYDZC交叉圆柱滚子转盘轴承的内圈或外圈有整体式和分体式结构之分,为减少滚子间的摩擦,通常设计有保持架或隔离块。
当载荷较大时采用满装滚子结构时,承载和抗倾覆能力增强,但摩擦阻力大,摩擦还易造成滚子间接触部位产生沿圆周方向的沟痕。
