CALCULATION OF THE PERMITTED MAXIMUM RADIAL AND AXIAL LOAD OF MOTOR MVR
Bearing 61803: C=1680 N, C0=930 N.
Bearing 6202: C=7800 N, C0=3750 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=(1680/P)3, where P=780 N.
Final result: Fr = 1000 N
(maximum radial force in the absence of axial load).
The maximum axial force in the absence of radial load is:
Fa = 1850 N
