      <abstract xml:lang="ru">
        <p>Эффективность пневматических перфораторов, долговечность и надежность их работы в большой степени определяются смазкой трущихся частей. Выполненные на заводе "Пневматика" исследования показали, что в условиях высоких динамических нагрузок, скоростей скольжения контактирующих поверхностей и повышенных температур в контактах, смазка существенно влияет на параметры перфоратора, особенно на крутящий момент, а также на темпы и характер износа основных трущихся деталей.</p>

      <abstract xml:lang="en">
        <p>The efficiency of pneumatic rock drills, the durability and reliability of their work are largely determined by the lubrication of the rubbing parts. The studies carried out at the Pnevmatika plant have shown that under conditions of high dynamic loads, high sliding speeds of contacting surfaces and increased temperatures in the contacts, lubrication significantly affects the parameters of the drill, especially its torque, as well as the rate and nature of wear of its main rubbing parts.</p>
