详细介绍: 推力滚针轴承AXK AXW AX NTA系类
推力滚针轴承或推力圆柱滚子轴承是在一套滚到垫圈间配置带保持架的滚针(滚子),保持架可靠地引导并夹持大量的滚动体,同一组件中的滚动体仅有极其微小的差异。推力滚针轴承或推力滚子轴承仅能支撑一个方向轴向负荷的轴承,可作为刚性良好且轴向占有空间最小的轴承配置。推力滚针轴承和推力滚子轴承的标准保持架为冲压钢板保持架,对于带保持架滚子套,务须采用能够以内径或外径进行引导的结构。
推力垫圈AS LS GS WS系类
推力垫圈AS系类是用高质量的弹簧钢冲压而成。其厚度为1mm,并经淬硬和抛光。当相邻部件表面钢性虽好但不宜作为滚到时,AS系类垫圈就充分发挥了它的作用。推力垫圈GS WS LS系类是用轴承钢制成并经淬硬处理。座圈GS外表面和轴圈WS内表面经过磨削制成。LS则是特别经济的车制外表面和内表面。推力滚针轴承或推力圆柱滚子轴承是在一套滚道圈(WS型及GS型)之间,配置带保持架的滚子(AXK型或K型),仅能承受单项轴承负荷的轴承。
使用带保持架滚子套时,因直接用轴或轴承室做滚到面,故可使设计紧凑。此时,滚到面须有HRC58-64的硬度和0.4a以上的光洁度。对于滚针轴承,用薄壁钢圈(AS型)做套圈,因此,即使在轴或轴承室不能进行热处理和精磨的情况下,也能进行紧凑的设计。
相关设计
轴承室和轴的支撑面必须平直于旋转曲线,在整个滚到宽度中轴承垫圈的支撑必须可靠,在采用AS系类垫圈时,务请认真核实内径 外径尺寸,使垫圈得到充分的支撑。在不用单独垫圈的轴承配置中,相关滚道的硬度应为HRC58-64,表面粗糙度Ra≤0.4um.当相关技术参数不能达到时,组件承载能力 使用寿命将显著降低。
