CALCULATION OF THE PERMITTED MAXIMUM RADIAL AND AXIAL LOAD OF MOTOR LFB(H).
Bearing 6001: C=5070 N, C
0
=2360 N.
Bearing 609: C=3710 N, C
0
=1660 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=(3710/P)
3
, where P=1722 N.
(maximum radial force in the absence of axial load).
Final result: F
r
= 650 N
(maximum radial force in the absence of axial load).
The maximum axial force in the absence of radial load is:
F
a
= 1000 N
