在交叉滚子轴承中，因圆柱滚子在呈90°的V形沟槽滚动面上通过隔离块被相

In the cross roller bearing, since the cylindrical rollers are arranged perpendicular to each other through the spacers on the V-groove rolling surface of 90 °, the cross roller bearing can bear radial load, axial load and moment load Multi-directional load. The size of the inner and outer ring is miniaturized, the ultra-thin form is closer to the limit of the small size, and has high rigidity, so it is more suitable for the joint part and rotary part of the industrial robot, the rotary table of the machining center, the rotary part of the manipulator, Precision rotary table, medical equipment, measuring instruments, IC manufacturing equipment and other equipment. <br><br>Rotation accuracy: Separation blocks are installed between the vertically arranged rollers in the bearing, which prevents the inclination of the rollers and the mutual friction between the rollers, reducing the rotational torque. In addition, compared with the previous use of steel plate retainers, there will be no roller edge stress concentration or locking phenomenon. At the same time, because the inner ring or outer ring is a two-part structure, the bearing clearance can be adjusted, and even if a preload is applied, it can rotate smoothly with high precision. <br><br>Types of crossed cylindrical roller bearings: <br>1, RB type (integral inner ring, split outer ring) This model is the basic type of crossed roller bearings. The outer ring is divided into two pieces, and the inner ring is a whole structure, which is more suitable for occasions requiring rotation accuracy of the inner ring. <br><br>2. The RE type (split inner ring and overall outer ring) is also the basic type of crossed roller bearings, with the same dimensions as the RB type, but the structure is integral with the outer ring and the inner ring is divided into two pieces, which is more suitable for use in Where the rotation accuracy of the outer ring is required. <br><br>3. RU type (integral inner and outer ring, with mounting holes), because the outer ring and the inner ring have mounting holes, there is no need to fix the flange and the support seat when installing. In addition, since the outer ring and the inner ring are integral structures, the installation has almost no effect on performance, so stable rotation accuracy and torque can be obtained, which is suitable for the occasion of rotation of the outer ring and the inner ring. <br><br>4. RA type (integral inner ring, split outer ring, ultra-thin) This model is a compact type that reduces the thickness of RB inner and outer rings to the limit. The structure is the same as RB type. The outer ring split structure is more suitable for weight. Light and compact design parts, such as the rotating part of the manipulator.<br><br>5. CRBH type (integral inner and outer ring type, ultra-thin), this model is ultra-thin RU, because of the ultra-thin design and no mounting holes in the outer ring and inner ring, flange and support seat are required for installation. In addition, since the outer ring and the inner ring are of an integral structure, the installation has no impact on performance, so stable rotation accuracy and torque can be obtained. It is suitable for occasions where the outer ring and the inner ring rotate but the size reduction is required. <br><br>6. SX type (integral inner ring, split outer ring, ultra-thin), under the same journal condition, this type has a smaller cross-sectional size than the RB type. Due to the ultra-thin design, the outer ring and the inner ring There is no mounting hole, and the flange and the supporting seat are required to be fixed during installation, which is suitable for the application of inner ring rotation.

在交叉滚子轴承中，因圆柱滚子在呈90°的V形沟槽滚动面上通过隔离块被相互垂直地排列，所以交叉滚子轴承可承受径向负荷、轴向负荷及力矩负荷等多方向的负荷。内外圈的尺寸被小型化，极薄形式更是接近于极限的小型尺寸，并且具有高钢性，所以更适合于工业机器人的关节部和旋转部、机械加工中心的旋转台，机械手旋转部、精密旋转工作台、医疗机器、计量器具、IC制造装置等设备。<br><br>旋转精度：轴承中垂直排列的滚子间装有隔离块，防止了滚子的倾斜和滚子之间的相互摩擦，减小了旋转力矩。另外，与以前使用钢板保持器相比，不会发生滚子的边缘应力集中或锁死现象。同时，因内圈或外圈是两分割的构造，轴承间隙可调整，即使被施加预载，也能高精度平稳地旋转。<br><br>交叉圆柱滚子轴承的类型：<br>1、RB型（内圈整体、外圈分体）此型号为交叉滚子轴承的基本型。外圈被分为两片，内圈为整体结构，它更适合用于要求内圈旋转精度的场合。<br><br>2、RE型（内圈分体、外圈整体）同样为交叉滚子轴承的基本型，外形尺寸和RB型相同，但结构为外圈整体，内圈分为两片，它更适合用于要求外圈旋转精度的场合。<br><br>3、RU型（内外圈整体、带安装孔），由于外圈和内圈都有安装孔，安装时不需要固定法兰和支撑座。另外，由于外圈和内圈均为整体结构，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，适用于外圈和内圈旋转的场合。<br><br>4、RA型（内圈整体、外圈分体、超薄）此型号是将RB型内外圈厚度减小到极限的紧凑型，结构和RB型一样外圈分体结构，更适合于需要重量轻、紧凑设计的部位，例如机械手旋转部位。<br><br>5、CRBH型（内外圈整体型、超薄），此型号是超薄型RU，由于采用了超薄设计而且外圈和内圈没有安装孔，安装时需要法兰和支撑座固定。另外，由于外圈和内圈均为整体结构，安装对性能没有影响，因此能够获得稳定的旋转精度和扭矩，适用于外圈和内圈旋转但有尺寸小型化要求的场合。<br><br>6、SX型（内圈整体、外圈分体型、超薄），在相同的轴颈情况下，此类型比RB类型有更小的截面尺寸，由于采用了超薄设计，外圈和内圈没有安装孔，安装时需要法兰和支撑座固定，适用于内圈旋转的应用场合。
