Abstract
The object of work is definition of loading on rollers of belt conveyor, and further creation of algorithm and computer program for definition of the maximum loading after which in bearings of the roller the jamming moment begins. The jamming moment, is a consequence of distortion of bearing rings and is one of the negative coefficients influencing working capacity and durability of the bearing. Certainly, non recurrent occurrence of the jamming moment will not lead to instant destruction of the bearing, but it is known that monotonous, uniform operation of the product without peak critical loadings and multiple repeating jamming moments can lead to jamming and thereof to bearing destruction. Scope of results application received by authors is method improvements of definition of loads of bearings and definitions of loading on rollers. The results of this work can be used at different research of belt and roller conveyors to increase reliability and durability of its knots.
