Lubrication method to prevent KOYO thin-walled bearing corrosion phenomena

KOYO bearing corrosion causes and prevention methods of thin wall bearing corrosion is caused by a variety of internal and external factors, sum up the main are: 1, metal surface finish, The oxygen concentration cell corrosion) 。 2, metal materials chemical composition and the structure itself. 3, contact with the metal surface composition and pH value of solution; 4, environmental temperature and humidity. 5, and various environmental medium metal surface in contact. 6, the other person's sweat is also causes of KOYO bearing corrosion, its pH value of 5 ~ 6. So in order to prevent hand sweat cause corrosion, installation and production personnel should wear gloves, don't contact thin wall bearing by hand. 1, the oil flow observation: take two cups, one of them need to be checked out of the lubricating oil, empty on the desktop, the other will leave the measuring cup with lubricating oil for high 30 - desktop 40 cm and tilt, let oil flow slowly to the empty cup, to observe the flow situation, quality thin wall bearing lubricating oil when the oil flow should be long and thin, uniform, continuous, if appear oil flow fast and slow, and sometimes has a large flow, the said lubricating oil has deteriorated. 2, hand twist: lubricating oil lay between the thumb and forefinger grinding, good lubricating oil hand feel less lubricity, wear debris, no friction, if feel fingers between the larger friction feeling such as sand, suggests that the impurity, lubricating oil can no longer use, a new lubricating oil should be replaced. 3, illumination method: on a clear day, use a screwdriver to lubricating oil lifted, and horizontal Angle of 45 degrees. Contrast sunshine, observe the oil situation, under the light, can see clearly without wear debris in lubricating oil is good, can continue to function, if excessive wear debris, lubricating oil should be changed. 4, oil droplets trace method: take a clean white paper, number of oil drops on the filter paper, after waiting for lubricating oil leakage, if the surface is black powder, touch resistance acerbity feeling, is the lubricant inside has many impurities, good oil powder, with the hand feels dry, smooth, and yellow. In KOYO bearing lubrication oil of turning resistance consists of the following factors: the design of thin wall bearing and load; Oil viscosity, the dosage and the speed of the bearing. Just when the dosage of the oil in the friction torque when the minimum contact surface to form a layer of film. But too much oil, the oil viscosity is high friction increases. Lubrication, however, to maintain the security and pay little attention to the desire of the friction loss, usually by a majority of advantage. This means that more oil, usually more heavy oil, will be used to reduce or leakage losses due to evaporation.
