SKF the main effect of the vibration of the wheel bearing lubrication

Rolling bearing vibration is basically caused by the vibration of the bearing ring, and bearing structure, stiffness, manufacturing accuracy, installation and usage and other factors. If there is a large roll SKF bearing inner ring road radial corrugated, which ring rotates the bearing outer ring to produce radial vibration. Waves of bearing inner ring will not only cause the radial vibration of outer ring, but also will cause the axial vibration of outer ring, bearing when the axial load can make the bearing inner and outer ring of the axial relative position changes, so the inner ring rotates the bearing outer ring, produce the axial vibration sieve mouth at work, for high-speed rotating bearing, caused by the vibration frequency of corrugated, likely to equal the vibrator shaft rotational frequency, which produce resonance. Lubrication of wheel bearing repair method: lubricated bearing internal smooth agent in general can be divided into two kinds of oil and grease. Repair method: prepare: dry towel, pliers, bearing cleaning night, bearing smooth smooth oil or grease. 1, boring: take the SKF bearing from cleaning fluid, with a dry towel wipe cleaning fluid, in the shade to dry again. 2, bearing cleaning fluid, soaked the bearing in the bearing cleaning fluid in the market to buy, and swing at this point, the bearing internal foreign body is swinging into, some shop ultrasonic cleaner to remove foreign bodies are sponsorship. 3, smooth agent injection according to the trend to inject grease or oil in the bearing, cover cover partial new install C type ring. 4, unload the C type ring and cover: with a dry towel to the inside of the bearing dirty stuff erase, and then carry with sharp pliers live C word on one side of the ring, take C type ring and shield. 5, test: for bearing already assembled into the original situation by hand grasp the inner ring line behind several turns. Friction is mainly refers to the abnormal vibration of rolling bearing vibration, in general friction vibration likely to occur in large ball bearing, especially with grease lubrication grease lubrication performance not good when are more likely to happen. According to the test and observation, SKF bearing friction vibration generation tend to have a direct bearing and lubricating oil properties. When the lubricant performance is bad or not clean, is prone to friction vibration, but also related to rolling bearing outer raceway machining quality, if the use of special precision machining method, can better control the friction vibration.
