The new double row cylindrical roller bearing of solid frame has a double row outer ring and a double row inner ring, and there are many rollers between the inner and outer ring, and the roller is supported by solid cage. In order to solve the problems of low dynamic load, short life and more consumption of bearings, the output of the factory and the increase of cost are affected. The dimensions are: the inner diameter of the bearing is d = 440mm, the outer diameter of the bearing is D = 640mm, the width of the bearing is T = B = 230mm. The roller bearing diameter, Dw, roller length L, the number of rollers per row and the value range of the roller are determined by the designer's first design method of rolling bearing. Compared with the existing bearing structure design of the same type, roller diameter and roller maximum length, the bearing ring and cage enough strength conditions, as much as possible to occupy the effective mining empty roller bearing, dynamic load amount increased, the growth of service life greatly, reduce customer cost. For steel, non-ferrous metallurgical metal industry rolling mill support roll or work roll, is a large type of bearing.
【技术实现步骤摘要】
实体架新型双列圆柱滚子轴承
本技术是一种双列圆柱滚子轴承,属特大型轴承。主要用于钢铁及有色冶金行业轧钢机支撑辊或工作辊上。属工程元件轴承类(F16C)、金属的轧制类(B21B)。
技术介绍
过去圆柱滚子轴承采用老方法设计,设计的产品滚子直径小,长度短,轴承的额度动载荷值低,使用寿命短,增加了轴承的消耗,换辊等辅助时间也加长,直接影响了钢厂的产量并导致成本增加。
技术实现思路
本技术提出了实体架新型双列圆柱滚子轴承,其目的就是解决上述老设计中双列圆柱滚子轴承额度动载荷值低,使用寿命短的问题。采用的技术方案如下:实体架新型双列圆柱滚子轴承,具有一个双列外圈1和一个双列内圈2,内、外圈间设多个滚子4,并由实体保持架3支撑,轴承的内径d,轴承外径D,轴承宽度T(B),分别为表1中的数值,其特征是一种型号轴承滚子直径Dw,滚子长度L,每列数量Z取值范围分别为表1的数值范围;表1为获取实体架新型双列圆柱滚子轴承的最佳效果,表1中轴承的滚子直径Dw,滚子长度L,滚子每列数量Z分别取表2中数值,即表1中删去公差后的公称尺寸的数值。表2本技术有益效果:本实体架新型双列圆柱滚子轴承是采用 ...
