SKF bearing noise problem caused by wrong installation

1, assembly on site must be kept clean. SKF bearing operation and service life is vital, to avoid bearing from dust, moisture and contaminants - Contaminants. 2, check the bearing hole and shaft with the surface, such as geometry and dimensional accuracy, and cleanliness. 3, in the bearing ring mating surface coated with a little oil or a little fat. 4, shaft and bearing hole has a 10 degrees - Guide the chamfering of 15 degrees. 5, condensation of water will lead to the matching of the bearing and the bearing surface rust, so don't be too cool SKF bearing. 6, after installation to the drill bearing loading lubricant, check whether the bearing configuration is working properly. Heating temperature of the bearing to the bearing size, the required amount of interference. Hot charging work related matters needing attention, the following points need to note: 1, will not be bearing heated to 120 degrees Celsius above; 2, to make the bearing is not direct contact with the bottom of the tank, it is best to consider put drill bearing metal two stage, or the SKF bearing hung; 3, will the drill bearing heating to 20 - higher than the required temperature 30 degrees Celsius, so that does not occur in the operation of inner ring cool, difficult to install; 4, after installation, bearing cooling down, width contraction, so use shaft nut, or other appropriate method, make it tight, in case of gap between inner ring and bearing retaining shoulder. Bearing retainer materials required by the performance: the size stability is good mechanical strength and good workability. According to different purposes and demands of its, impact resistance, heat resistance, good corrosion resistance. Bearing ring and rolling body material: ring and rolling body usually use high carbon chromium bearing steel. Most SKF bearing, using JIS SUJ2 steel grade. Use SUJ3 large bearing. Further need impact resistance, used as a bearing material nickel chrome steel, chrome molybdenum steel, chrome molybdenum steel, using carbon quenching, make the steel from the surface to the appropriate depth has a hardening layer. With appropriate hardening depth, fine structure, suitable hardness hardness of surface and the core permeability of coal bearing, than using the bearing steel bearing has excellent resistance to impact, the average permeability coal bearing steel chemical composition. SKF bearing retainer materials: punch retainers material, using low carbon steel. According to different purposes, also used brass, stainless steel plate. Cutting system maintains a material, the use of high-intensity brass, carbon steel, and also the use of synthetic resin.
