交叉滚子轴承简介

交叉滚子轴承是一种内圈分割、外圈旋转 的特殊型号轴承。有两大类组成,一种是交叉圆柱滚子轴承,另一种是交叉圆锥滚子轴承;与传统型号相比,刚性提高3~4倍,交叉滚子轴承在国外已经有很长的应用历史,但在国内也仅仅是最近几年才进入大众的视界,由于自身的特殊性和拥有其他轴承所不可比拟的优越性而被广泛使用。此型轴承广泛运用在如工业自动机械人、工作机械及医疗设施等,需要刚性高、紧密及高转速下仍能确保精确之场合下。

交叉滚子轴承使用特点

1、具有出色的旋转精度
交叉滚子轴承内部结构采用滚子呈90°相互垂直交叉排列,
滚子之间装有间隔保持器或者隔离块,可以防止滚子的倾斜所滚子之间相互磨察。另外,不会发生滚子的一方接触现象或者锁死现象;同时因为内外环是分割的结构,间隙可以调整,即使被施加预压,也能获得高精度的旋转运动。
2、操作安装简化
被分割成2部分的外环或者内环,在装入滚子和保持器后,被固定在一起,所以安装时操作非常简单。
3、承受较大的轴向和径向负荷
因为滚子在呈90°的V型沟槽滚动面上通过间隔保持器被相互垂直排列。
4、大幅节省安装空间
交叉滚子轴承的内外环尺寸被最小限度的小型化,特别是超薄结构是接近极限的小型尺寸,并且具有高刚性,所以最适合于工业机器人的关节部位或者旋转部位、机械加工中心的旋转工作台、机械手旋转部、精密旋转工作台、医疗仪器、计量器具、IC制造装置等广泛用途。
5.转速能力高
6.减少轴长度和加工成本,热膨胀导致几何尺寸的变化有限
7.采用尼龙分隔器,转动惯量低,启动扭矩低,易于控制角分度
8.优化预紧力,刚度大,引导滚子运转精度高
9.渗碳钢提供优良的抗冲击力和表面抗磨能力
10.简单但润滑充分

交叉滚子轴承类型分类

RB型(外圈分割型)
RB系列型号为交叉圆柱滚子轴承的基本型,内、外环尺寸被最小限度地小型化,其构造是外环是分割型,内环是一体设计,适合于要求内环旋转精度高的部位。
RE型(内圈分割型)
RE系列型号是由XRB型的设计理念产生的新型式,主要尺寸与XRB型相同。其构造是内环是分割型,外环是一体设计,适合于要求外环旋转精度高的部位。
RU型(内、外圈一体型)
RU系列型号由于已进行了安装孔的加工,就不需要固定法兰和支撑座。另外,由于采用采用带座的的一体化内外环结构,安装对性能几乎没有影响,因此能够获得稳定的旋转精度和扭矩。能用于外环和内环旋转。
RBC型(外圈分割型)
RBC系列型号(对应IKO公司CRBC系列)其构造是外环是分割型,内环是一体设计,带保持架满装滚子轴承。适合于要求内环旋转精度高的部位。
CRBH型(内、外圈一体型)
CRBH系列型号内、外环都是一体结构,用于外环和内环旋转。
RA型(外圈分割、超薄型)
RA系列型号是将RB型内、外环厚度减小到极限的紧凑型。适合于需要重量轻、紧凑设计的部位,例如机器人和机械手旋转部位。
SX型(外圈分割型)
SX系列型号结构与RB系列类似,外环是两分割的结构,通过三个弹簧卡环连接,内环一体设计,适用于要求内环旋转精度高的地方。
XRU08型(内外圈一体型)
XSU08系列与RU系列相近,内外环已进行了安装孔的加工,就不需要固定法兰和支撑座。由于采用采用带座的的一体化内外环结构,安装对性能几乎没有影响,因此能够获得稳定的旋转精度和扭矩。能用于外环和内环旋转。
