Abstract: The paper presents an analysis ofthe stress deformation state o f shafts o f characteristic drive pulleys on belt conveyors in Drmno open pit mine. The shape and dimensions o f the shafts were defined based on the original technical documentation, and the stress state was verified by applying the finite difference method in the Catia software package. Loads were simulated for real working conditions in exploitation. The analysis results showed that shafts with cone between locking device and bearing have the best load distribution and that T-shaped end disks most favourably transfer loads to the shaft. The analyses also showed that the values o f stresses formed in shafts at the failure site are not high enough to lead to shaft failure due to overload and that failure cause should be sought in fatigue, then in plastic deformation, residual stresses after shaft repair and pulley weight unbalance.
