The article describes promising structures of clip (screw and friction) connections with incomplete sweep of shaft used in machines and mechanisms for the oil and gas industry. The contact problems of interaction between semi-hubs and shaft for the symmetric and asymmetric connections are formulated. For structures that are asymmetric relatively the joint bolt two types of interaction are investigated: with and without lateral displacement. Based on a priori assumption about the distribution laws of contact pressure accepted in traditional courses of "Machine Details" an engineering method for calculating of clip connections is developed. Herewith different types of details coupling (with a gap, matched, with tension) correspond to concentrated, cosine and sustainable (linear) distributions of contact stresses. There are determined an analytical dependences of boundary points and breakloose force on spanning angles, bolt tightening force and tribological properties of joined parts of subassembly.
