摘要
突破了用表面修形来降低或避免滚子轴承边界应力集中的传统理论和方法,通过设计创新来降低或避免轴承 滚子边界应力集中,提出了一种新型滚动体轴承--深穴空心滚子轴承。新型圆柱滚子轴承兼备了对数滚子轴承和 空心滚子轴承的优点,又克服了它们各自的缺点。理论研究表明这种新型滚动体轴承具有突出的优点:①解决实心 和空心直母线滚子轴承的接触应力和等效应力的边界应力集中的问题。②使轴承在具有对数滚子轴承可克服边界应 力集中的优点的同时,避免了在加工工艺上的超精加工的要求。③保持了空心滚子轴承的优点,如:适应振动冲击 性载荷,改善轴承系统的润滑冷却条件,重量轻,减少了外圈所受的离心力,具有较好的高速运转性能等等。
Breaking through the conventional theory and method with design innovation, a novel roller bearing-deep cavity hollow cylindrical roller bearing is proposed in order to decrease or prevent the stress concentration on the ends of the roller. The research based on theory indicates that the deep cavity hollow cylindrical roller bearing has outstanding performance. With the advantages and without the disadvantages of both logarithmic profile roller bearing and hollow cylindrical roller, the novel bearing is able to eliminate or decrease the sharp edge stresses effect of both contact stresses and equivalent stresses, to prevent super-precision manufacturing and to keep the merits of the hollow roller bearing such as adapting to vibration and impact loads, improving the lubricating and cooling condition, light, less inertial forces on the outer ring and better high speed performance, etc.
