In the paper stress analysis of rotary kiln support rollers is conducted. Stress state in the support rollers is caused by temperature gradient, shrinkfit connection between shaft and roller and by the contact with kiln ring. The stress analysis is done analytically and numerically, and the results obtained are compared....
