Abstract: Connection of revolving and nonrevolving bonds in construction and transport mechanization machines have developed under the influence of various operating and structural requirements. However, the current conceptual solutions do not provide a long and reliable life of indirect elements (bearings with big diameter). Research and development of new conceptual solutions for connection of revolving and nonrevolving bonds in construction and transport mechanization machines, in this paper are based on an analysis of torsional rigidity of various alternative solutions. Forming the theoretical calculation model of the carrying structure of radial-axial bearings has resulted in a degree of reduction of influential parameters and the theoretical dependence of corresponding geometric characteristics of carrying structure has been established. Thus, without violating the generality of the observed problem, a base has been created to research and develop the new concept for connecting revolving and nonrevolving bonds which eliminates the influence of terrain roughness on support surface deformation of radial-axial bearing.
