Bearing corrosion is common, answers and solutions

Bearing corrosion is common, causes and solutions, will reduce the service life of bearing. So we should pay attention to the problems in daily work. High temperature bearing corrosion to determine the causes and prevention methods, first of all, see the high temperature bearing corrosion caused by what, generally divided into the external cause and internal cause. 。 Metal surface finish, The oxygen concentration cell corrosion) 。 。 Chemical composition and the structure of metal materials. 。 Solution composition and value of contact with the metal surface. 。 The environment temperature and humidity. 。 Contact with the metal surface of various environmental media. The sweat of others is also a cause of corrosion, the value of. Therefore, in order to prevent hand sweat corrosion, installation and production personnel should wear gloves, don't touch the hand of the high temperature bearing. Tu rust-proof oil to prevent high temperature bearing rust:. Soak methods: some small high temperature bearing immerse in antirust grease, by controlling the temperature of the antirust grease or viscosity to achieve oil film thickness. Attached a layer of anti-rust oil on its surface method. Evenly brush method: brush, pay attention to in high temperature bearing surface, do not produce accumulation, also should pay attention to prevent leakage. Spray method: some big rust inhibitor is not applicable to immerse oil, commonly used pressure filtering compressed air spray where clean air. Spray method using solvent XiShiXing rust-proof oil or thin layer of anti-rust oil. This method correct fire prevention and labor protection measures must be taken. Bearing the load rotation, internal and external raceway and rolling, due to the rolling fatigue and designed stripping phenomenon. The load of stripping bearing damage reason: too many bad installation ( Nonlinear) , torque load, foreign invasion, into the water. Poor lubrication, lubrication is undeserved, improper bearing clearance. The accuracy of bearing box is bad, uneven stiffness of bearing box, the deflection of shaft rust, corrosion, scratches, and indentation ( The surface deformation) The development of the cause. What measures should be taken to solve the bearing stripping damage check load and the bearing again used to improve the size of the installation method, improve the sealing device, prevent rust. Use appropriate viscosity of lubricant and lubricating method improvement. Check the shaft and bearing box precision inspection clearance. Bearings, comfortable and durable, )
