Improving the Technology for Producing Pressure Couplings of Bushing-Housing Parts by Using a Power Drive Made of an Alloy with the Shape Memory Effect

The article describes the technology of using a power drive made of an alloy with the shape memory effect to improve the quality of the pressure couplings of bushing-housing. A comprehensive assessment of the existing approaches to the production of a pressure coupling is performed. The risk analysis of the technological process of pressing by the FMEA method is carried out. The flow diagram of the proposed process and the results of an experimental study of the dependence of contact pressures on the radial expansion of a ring load-bearing element made of an alloy with the shape memory effect are presented.
