FAG bearings and bushings, seat, bearing hole clearance fit transition, bi-directional thrust bearing rings should be fixed on the shaft, to prevent the axis bearings installation method, under normal circumstances, most cases, shafts, therefore draw of the inner ring and shaft, bearings and bearing clearance fit.
FAG bearing installed, you should check ring and bushings center line of axis vertical indicator fixed in tank body Shang, will faced touch bearing, axis above of bearing roll road of table head, while observation indicator pointer, if pointer deflected, description ring and bushings of axis not vertical center line box shell hole more deep Shi, head also can using dial test instrument of extends bearing of installed is correctly, seat can automatically adaptation body, to ensure the institutions is is located in upper and lower roll road if loaded anti-has, not only bearing not normal work, And tie surface will was serious wear due to bearing block ring and ring of differences also not is clearly, Assembly should carefully, not got wrong also, bearing block ring and block hole Zhijian left has 0.2-0.5mm of gap, to compensation parts of processing, installed errors caused of not accurate, operation Center offset bearing ring, this space, to ensure its automatically adjustment, avoid contact friction of normal operation or, FAG bearing will caused serious damage.
1. assemble the scene should be as clean as possible, and free of dust.
2. to avoid contaminants and moisture-bearing contaminated dust, pollutants have adverse effects on the operation and service life of the bearing.
3. check the bearing bore and the mating surfaces on the shaft: geometric and dimensional accuracy and cleanliness.
4. the mating surfaces of the bearing rings coated with a little oil or a little fat.
5. ensure that the shaft and housing bore has a leading chamfer of 10-15 degrees.
6. not too much cooling bearings: condensation moisture can cause the FAG of mating surfaces of the bearing and bearing corrosion.
7. after installation: FAG bearings filled with lubricant, check that the bearing arrangement is working properly.
