详细介绍:
|
螺栓滚轮轴承(又名曲线滚轮轴承) 螺栓型曲线滚轮一般为满装滚子结构,螺栓轴滚道部位经过淬火,为避免应力集中,滚轮的厚壁外圈外表面为弧形。外圈有两个整体挡边,轴向由滚子引导。螺栓轴头部和压装的侧挡圈通过滚子为外圈提供轴向支承。 KR系列,KRV系列,NUKR系列等螺栓型滚轮滚针轴承是由G20CrMo螺栓轴经过HVI≥664,有效硬化层1.3mm精制而成,再由作为滚子组内滚道的螺栓及一个厚壁外圈组合。螺栓轴的台肩及压在螺栓上的端面挡圈组成了外圈沿两个侧面方向的引导面。当曲线滚轮在平滚道或凸轮盘上运动时,由于外圈的弹性变形,滚轮的内应力加大。因此应用于此种工作情况下的额定负荷请选择曲线滚轮一栏:(以下为详细说明)除此之外我司还可定制大外径CF,CRY,CYR,NCF等系列滚轮轴承。
