Imported bearing in use, is an important characteristic of lubricating oil viscosity, viscosity directly affects the liquidity of lubricating oil and the size of the friction surface is formed between the oil film thickness, the more speed Gao Yingxuan lower viscosity, the more load weight should choose high viscosity. Commonly used lubricating oil machine, high-speed machine oil, turbine oil, compressor ( compressor) Oil, transformer oil, cylinder oil, etc. Imported bearing lubrication what method is there? China bearing network according to the summary tell everyone basically has the following kinds: 1, oil bath lubrication oil bath lubrication is the most common lubrication method, suitable for low, medium speed, bearing ( 轴承) Lubrication, imported bearing part of the immersion in the slot, lubricating oil, 润滑油) By the rotation ( 旋转) Bearing parts take up, and then flow back to the oil level of oil tank should be slightly lower than the lowest at the center of the roller. 2, drip lubrication ( lubrication) Oil drip lubrication ( lubrication) Suitable for the need to ration oil imports bearing ( 轴承) Components ( 装配单元) , the drops of oil every 3 - in general A drop of it is advisable to 8 seconds, too much oil will cause the bearing temperature increased. 3, circulating oil lubrication, lubrication) With the oil pump ( 深井泵) To filter the oil transfer to the bearing parts, after bearing lubricating oil ( 润滑油) Filter used after cooling ( 使用) 。 Due to the circulating oil can take a certain quantity of heat, cooling the bearing, therefore method is suitable for high speed bearing parts. 4, spray lubrication with dry compressed air sprayer and lubricating oil mixed form oil mist, spray bearing ( 轴承) , can effectively make the bearing cooling airflow and can prevent the intrusion. This method is suitable for high speed and high temperature bearing parts ( 装配单元) The lubrication. 5, spray lubrication oil pump to pass through the nozzle shot into the bearing, high pressure oil into the bearing of the bearing at the other end into the oil in the tank. Imported bearing with higher rated load, low noise, greatly reduce warranty costs, increase the machine running time, etc; When in identifying such imports bearing true and false, but through touch to play on the bearing steel is more quick and more accurate to identify, the seal by hand touch, without a touch, but the use of nails touch can feel the existence of the steel seal on the seal. When bearing at high speed, rolling element and cage also with very high rotation speed, 转速) Degree of the surrounding air flow formation, in general it is difficult to be sent to the bearing lubricating oil lubrication method, then must use the method of high-pressure jet spray the lubricating oil to the bearings, the position of the nozzle should be placed between inner ring and retainer center.
