To the choice of materials of working and distributive links of by displacement hydraulic mashines for the needs of building-travelling industry.

Abstract

Search of ways of increase of technical level and reliability of by hydraulic fluid power of rotatory motion for building and travelling machines. Analysis of designer and technological decisions in part of choice of materials of pairs of friction of working links and distribution of working liquid in by displacement hydraulic mashines – pumps and hydraulic motors with the purpose of acquaintance of specialists with advanced experience in this type of technique. Method. On the basis of mathematical model of dynamics of hydraulic fluid power by means of application of VisSim package the estimation of intensity of height of extreme values of pressures is conducted from character of action of the external loading on hydraulic motor at starting of hydraulic fluid power. Results. It is set that in by hydraulic fluid power can take place substantial vibrations pressures exceeding almost in two times the set values in the technological mode of operations of machine. Conclusion. Depending on the fast-acting of loading on hydraulic fluid power of machine a preliminary dynamic design the value of the capacity of hydraulic motors gets out on results that is recommended for providing of supply on working pressure. The brought information over about the applied pairs of friction of hydromashines and their thermo-chemical treatment can be useful to the specialists at planning of new hydraulic mashines, and repair of exploited.

Показано, что в объемных гидроприводах для строительных и дорожных машин путем усовершенствования узлов трения существенно повышены номинальные давления и снижена материалоемкость гидромашин – насосов и гидромоторов. В зависимости от быстродействия нагрузки на гидропривод машины, для обеспечения запаса по рабочему давлению рекомендовано предварительное динамическое моделирование, по результатам которого выбирается значение рабочего объема гидромотора.

У статті показано, що в об’ємних гідроприводах для будівельних і дорожніх машин через удосконалення вузлів тертя істотно підвищені номінальні тиски й понижена матеріаломісткість гідромашин – насосів і гідромоторів. Залежно від швидкодії навантаження на гідропривід машини, для забезпечення запасу щодо робочого тиску рекомендовано попереднє динамічне моделювання, за результатами якого вибирається значення робочого об’єму гідромотора.
