双圆柱滚子轴承有两个结构:圆柱形内孔和锥形内孔。This kind of bearing has the advantages of compact structure, large rigidity, large bearing capacity and small deformation after loading. double cylindrical roller bearing is suitable for machine tool spindle.锥形内孔还可以在稍微调节间隙时发挥作用,并且可以简化定位装置的结构并便于安装和拆卸。

常用的双圆柱滚子轴承具有以下形式:

NN0000双圆柱滚子轴承这种轴承结构紧凑,在负载下变形小,因此特别适用于支撑机床主轴。因为外环没有法兰,外圈和内圈部件(带滚子和笼)可以单独安装,这不限制轴或壳体的轴向位移,并且与单个相比可以承受更大的径向载荷- 具有相同径向尺寸的圆柱滚子轴承。

NN0000K conical hole double cylindrical roller bearing这种轴承结构紧凑,负载变形小,因此适用于支撑机床主轴。轴承的内孔是锥形的,其可以略微调节轴承的径向间隙。因为这种类型的轴承的外圈没有法兰,所以外圈和内圈部件(带辊和笼)可以分开安装,这不限制轴或壳体的轴向位移。与具有相同径向尺寸相同的单排圆柱滚子轴承相比,它可以承受更大的径向载荷。

Both types of双圆柱滚子轴承请勿限制轴和壳体之间的相对轴向位移,并且适用于不定位轴承。The cage of this type of bearing mostly adopts the car-made solid cage.

NNF型双圆柱滚子轴承是双排全负载圆柱滚子轴承,不仅可以承受径向载荷和轴向载荷,而且倾覆的时刻,因此通常用作固定轴承。

NNF类型双圆柱滚子轴承是一种结构,其具有两个内圈,双肋和一个外圈,具有中间肋。辊子由双内圈的保持边缘引导,并且两个内圈通过紧固环固定在一起。NNF轴承的两侧采用触点密封。轴承充满油脂。当single-row cylindrical roller bearings with flanges on the inner and outer rings are selected, the axial load capacity should be calculated, and its value is related to the radial load and lubrication method.润滑脂的工作温度为-50℃至+ 110℃,但由于油封材料的限制,轴承的工作温度受到-40℃至+ 80℃。Under good service conditions, NNF bearing with oil seal does not need to be maintained. If the bearing is exposed to water vapor or polluted environment for a long time, and it runs at medium and high speed, the bearing can be supplemented with lubrication through the lubrication groove and lubrication hole on the outer ring.

双圆柱滚子轴承的应用主要用于机床主轴,冶金设备,重型机械,提升设备等。
