CALCULATION OF THE PERMITTED MAXIMUM RADIAL AND AXIAL LOAD OF MOTOR P
Bearing 6203: C=9560 N, C0=4750 N.
Bearing 61805: C=4630 N, C0=2600 N.
Using the formula for dimensioning the bearings, the result is:
L10=(C/P)3 , where L10 = duration in millions of rotations
C = dynamic load coefficient
P = equivalent dynamic load on bearing.
Taking the number of cycles before failure as 10 million, the result is:
10=(4360/P)3, where P=2024 N.
Final result: Fr = 1500 N
(maximum radial force in the absence of axial load).
The maximum axial force in the absence of radial load is:
Fa = 2000 N
