单列向心球轴承尼龙保持架产品结构及模具尺寸表中的套圈宽度b,球数Z球径△,兜孔R_c及浪形保持架尺寸,均按滚动轴承专业标准图Q/Z55—67,Q/Z56—67选取.一、尼龙保持架的设计尼龙保持架结构见图1.这种结构简单,省料,具有一定的刚度和强度.经初步试验发现,尼龙保持架在高温、高速运转情况下,保持架受离心力的作用,有向外扩张,兜孔有增大的现象.为了有效地消除保持架外径与外圈挡边相碰,有意识地将尼龙保持架包球量减小,内径包球量适当增大,并在保持架外径作α=3°-4°斜度.下面所列公式及数据,是依据200、300系列共计34个轴承型号系列化设计总结得出,仅供参考,有待在生产中验证加以修正.
Single row radial ball bearings nylon cage product structure and die size table ferrule width b, ball number Z ball diameter △, pocket R_c and wave cage dimensions, according to the professional standards of rolling bearings Q / Z55-67, Q / Z56-67 selected First, the design of nylon cage Nylon cage structure shown in Figure 1. This structure is simple, save material, with a certain degree of stiffness and strength of the preliminary test found that nylon cage in high temperature, high speed operation Case, the cage by the role of centrifugal force, outward expansion, pockets have increased the phenomenon.In order to effectively eliminate the outer diameter of the cage and the outer edge of the collision, the ball will deliberately reduce the amount of nylon cage , The amount of ball inside the appropriate increase in the amount and the outer diameter of the cage for α = 3 ° -4 ° gradient The following formulas and data are based on 200,300 series total of 34 bearing model series design concluded , For reference only, to be verified in the production to be amended.
