352226X2—3(原197726)型轴承零件几何形状的改进

Improvement of Geometric Shape of Parts on Bearings Type 352226X2 3(Original Type 197726)

根据弹性流体动力润滑理论，对３５２２２６Ｘ２—３型轴承内圈大挡边和滚子的几何形状提出了改进建议。认为，只要将滚子大端的球面半径改为６７．５２ｍｍ，将大挡边的倾斜角改为１．

According to the hydrodynamic lubrication theory,suggestions for improving geometric shapes of the big collar of inner ring and roller of the bearing type 352226X2-3 are put forth.It is considered that simply by changing the spherical radius of the big end of the roller to 67 52 mm,the inclining angle on the collar to 1 16°,can the lubrication condition between the collar and roller be greatly improved。
