Abstract
Connections between rotating and stationary structures of transportation and building machines have been developed under the influence of various working and constructing requirements. So far the solutions have been based on rotating and stationary structure in the form of letters H and X. However, these concepts do not provide reliable and long-lasting operation of indirect elements (bearings of big diameters) inserted between the rotating and stationary members of the following machines: excavators, column cranes, truck cranes, and portal cranes. Research work and development of new structures of the connections between rotating and stationary structures of transportation and building machines, which make the basis of the project, are based on the analysis of torsional stiffness of possible structures. Theoretical calculation model of carrying structure of the bearing has been formed, influencing parameters have been reduced, and theoretical dependence between appropriate geometrical characteristics of carrying structure has been established. The theoretical dependences relevant for connection quality have been verified by experiments made on the carrying structure of an excavator. The final result which will be reached by this project is a new concept of connection between rotating and stationary structure of transportation and building machines.
