Nyzhnik O. A raise of a reability and operational rating of metallurgical machines drives with use safety device - damping couplings.

Safety device-damping coupling. The inсrease of reliability and operational rating of metallurgical machine drives, that works in shock-impulse load modes, with use of device-damping couplings include the hydrocylinder and power-accumulator systems. Mathematical simulation, theory of experiment planing, computer. It is created the concept of metallurgical machines guard with shock-impulse load modes. Are investigated the hydrocylinder and power accumulator systems and is proved possibility of their use in device-damping couplings of metallurgical machine drives analytically. It is developed the unified method of elastic elements in device-damping couplings account. The method of hydrocylinder parameters optimization is formalized. The elements of hard load hydrocylinder construction are investigated and the dependence of influence the main structural and operational factors to their serviceability is introduced. Two constructions of device-damping couplings are offered, on which the s olutions about issue of the patents on the inventions are obtained. The methodical guard is developed at the choice of optimum parameters of devise -damping couplings and project of the coupling introduced on ОАS "КB Кокsohymmach". The methodical guard to optimum designing of hydrocylinders and automation of researches processes introduced in DоnSIImеt are developed. Reduction of number of failures number of the metallurgical equipment, magnification of operation term. On metal works, research institutes, in educational process in high schools
