Fatigue life analysis of slewing bearings in wind turbines

Jun 01, 2018· The final wind turbine slewing bearing fatigue life theory estimate is 9.65 × 10 5 revolutions. (7) T 1 = Lnm ∗ Z = 88, 21, 000 where T 1 is the theoretical calculation of the nuer of raceway stress cycles. The slewing bearing test platform was used to conduct the test at a test speed of 4 rpm.

Effects of supporting structure and bolt connection on the

Nov 12, 2016· The preload is applied on the bolt by a few pretension elements. The ball–race contact forces, fatigue lives, and carrying capacities of the slewing bearing in the four models are calculated. The effects of supporting stiffness, bolt nuer, and bolt preload on the contact force and fatigue life of the slewing bearing are studied.
