双列向心球面滚子轴承在起重运输机械、重型矿山机械、列车、舰船等方面应用得较多.如果在这类轴承的装配时,采用预加载荷调整工艺,并使轴承按最佳寿命选择最佳载荷,这样不仅可以提高轴承的刚度和精度,还能提高轴承的承载能力,延长轴承的使用寿命。所以,国外有关高等院校、科研单位和制造厂商对此都很感兴趣。本文就这课题在理论推导和设计计算方法方面介绍如下。一、滚动轴承预加载荷的分析图1(a)为双列向心球面滚子轴承113000型,其内环有锥度为1:12的圆锥孔;图1(b)为13000型,它带有圆锥紧定套.这类轴承可通过预紧的方法来控制轴承的装配游隙,从而实现预加载荷和预加过盈的目的。
Double row radial spherical roller bearings in the lifting of transport machinery, heavy mining machinery, trains, ships, etc. more used in this type of bearing assembly, the use of preload adjustment process, and the bearings according to the most Good life choose the best load, so that not only can improve the bearing stiffness and accuracy, but also improve the bearing capacity and prolong the service life of the bearing. Therefore, foreign institutions of higher learning, research institutes and manufacturers are very interested. This article on the subject in the theoretical derivation and design and calculation methods are as follows. First, the analysis of the preload of the rolling bearing Figure 1 (a) for the double row radial spherical roller bearings 113000, the inner ring taper 1:12 taper hole; Figure 1 (b) for the 13000 type, with Conical sleeve.This type of bearing preload control method can be used to control the bearing assembly clearance, in order to achieve the purpose of preloading and preloading.
