Annotation: The paper is about the results of the analysis of the mode of deformation of the joints of guide pulley resting on sub-pulley structures of a shaft frame-type headgear which is presently under operating conditions. The analysis was done by the design model consisting of plane and solid finite elements and which was realized in the program «LIRA». Due to the numerical results, there were revealed the regularities of local stresses distribution under a guide pulley bearing; parameters of a plane stress under both emergency and normal working loads were found out. On the numerical simulation the guidelines to improve the construction of the joints of guide pulley resting on the sub-pulley frame-type structures were worked out. In whole, the results obtained are the base to improve the engineering procedures of designing steel structures of shaft sloping headgear.
Keywords: shaft frame-type sloping headgear, sub-pulley structures, joint of a guide pulley resting, design diagram, mode of deformation, local stresses.
