The dissertation contains results of experimental and analytical researches of the reasons of failures and wear of hermetic rotational refrigerating compressors (HRRC), theoretical analysis of wear resistance of details of HRRC on a base of molecular-mechanical theory of wear and recommendations at the choice of materials for their manufacturing. The results of comparative tests of three modifications of the hermetic rotational compressor FHR-500-1(2) are resulted, which testify, that the best design is the compressor with the fixed rotor not having a wear of the blade along the height with the least values of all details in comparison with the serial compressor are given.
