Embodiment 1
[0064] Taking a certain type of double-row four-point contact ball bearing as an example, the structural parameters and material parameters are as follows:
[0065] , , , , , , . The ultimate working conditions of this type of bearing are: axial force , overturning moment , F r =0kN.
[0066] The allowable contact stress of the four-point contact ball bearing is 4200MPa, and the safety factor ,but .
[0067] The method of designing the original contact angle of the bearing using the accurate static load curve is as follows:
[0068] Step 1: Calculate the normal contact load and maximum contact load between the steel ball and the inner and outer raceways according to the external load.
[0069] Given bearing inner ring displacement An initial value, obtained by formulas (1), (2), and (4) A , A 0 and , the result is substituted into formula (10) to get ; Then by formula (9) to find , from formula (6) to get ;Bundle and Substitute into f...

[0076] Taking a certain type of single-row four-point contact ball bearing as an example, the structural parameters and material parameters are as follows:
[0077] , , , , . The ultimate working conditions of this type of bearing are: axial force , overturning moment , F r =0kN.
[0078] Step 1: Calculate the normal contact load and maximum contact load between the steel ball and the inner and outer raceways according to the external load.
[0079] Given bearing inner ring displacement An initial value, obtained by formulas (1), (2), (3) A , A 0 and , the result is substituted into formula (10) to get ; Then by the formula (9) to find , obtained by formula (5) ;Bundle and Substitute into formula (7), and let F r =0, yes and Carry out continuous value acquisition, according to the formula (7), use the Newton-Raphson method to find out each group of working conditions ( , , F r ) Displacement of inner ring of lower bearing The final...
