Use the porous characteristics of the raw materials or the affinity characteristics of the lubricating oil; before the application of the bearing device; make the lubricating oil moisturize the bearing material; the bearing operation time can be added without adding or lubricating oil for a long time; this kind of bearing is called oil bearing. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
The oil-impregnated bearing is in non-working condition; the lubricating oil overflows its pores; when working; the shaft reversal heats due to the conflict; the thermal expansion of the bearing shell reduces the porosity; the è°‘ è—è ¡é¸µç»¯è§¯ 胫岢 胫岢 湎 当 当. Cooling; pore recovery; lubricating oil is sucked back into the pores.
Although the oil-bearing bearing can form an intact oil film; but in most cases; this kind of bearing is in a mixed conflict condition of the oil film.
The data can be used to make the oil-bearing bearing bushings of the oil-filled pores: wood, growing cast iron, cast copper alloy and powder metallurgy grinding data, which can use the affinity characteristics of the data and the lubricating oil; The oil bearing bearing bearing material in the guess is mostly polymer; such as oleic phenolic resin.
Recommend to friends comments close window Bearing related knowledge The "damage and discrimination" of SKF bearings in the industry is detailed. The layout of the fine instrument bearing and the failure of the brake valve are analyzed. The influence of the metal wear self-correcting skill on the bearing life. The rolling bearing is tightly cooperating with the outer ring. The door is improved by the Osaka University of Japan. Ring data progress bearing heat resistance (Figure)
