1) the wear and tear of improper lubrication
Surface wear mirror zhuang, color is blue or brown. This situation is caused by insufficient lubrication, should improve the lubrication condition, to determine the lubrication cycle and oil seal.
2) the dent that caused by improper installationInner and outer ring work surfaces have the dent spacing is equal to the distance between the roller and the reason for this is when installation has not hit on the right ring, or on the cone shaft promote excessive, or in the stationary state load caused by overload.
3) foreign bodies caused by indentation
Work surface and roller surface around the indentation, may be installed into the foreign body or lubricant foreign body and the surrounding environment, etc. Bearing installation clean, use a clean lubricant and check the oil seal.
4) roller end surface scratches
On the friction roller end face and guide the guard, Nick and discoloration. This situation is due to the excessive axial load caused by sliding or insufficient lubrication. This damage can choose higher viscosity of lubricant.
5) roller and raceway grinding
At the beginning of the race load area end mill with roller and local color, this is because the roller into the load zone, caused by the sudden acceleration. There are two kinds of feasible methods: one is to choose the high viscosity of lubricant; The other is reducing the bearing clearance.
6) the surface abrasionInner bore and the external surface of the outer ring is scored and local color, this is a ring or bearing housing and shaft caused by relative motion.Is the only way to solve the increasing ring and shaft or the bearing box with interference quantity to prevent turning to each other. The axial braking or clamping cannot solve such problems.
