Install the FAG bearings, to facilitate the inspection bearing code, not an error, the bearing ring type side arrangement and installation.
The heating shell hole 1 of the bearing and the bearing seat:
For a large amount of surplus, large bearing, in order to facilitate the installation, must be installed before heating; for light metal bearing shell hole tightly matched ( such as aluminum bearing seat ), because of very low hardness, surface for the prevention of FAG bearing outer ring press bearing shell hole is scratched, napping, should also be heated installation. Heating method, is generally bearing or the separation bearing ferrule, put into a clean oil tank, the oil submerged non-standard bearings, uniform heating. The temperature reached 80℃ - 90 ℃, remove the clean, hot installation. The tank can be made of 2 - 3mm thick iron plate, from the bottom of 50 - 70mm high with a porous plate, bearing is arranged on the porous plate heating. Its purpose is to avoid the precipitation of impurities in the oil into the bearing.
2 choose to cooperate with the basis
According to the rotation of the loads acting on the bearings relative to the ring, load FAG bearing ring bearing has three kinds: local load, cyclic load, oscillating load. Usually cyclic loading ( axial rotation ), oscillating load the tight fit; local load in addition to the special requirements on the use of, not the tight fit. When non-standard bearing under dynamic load and is a heavy load, inner, outer ring shall be used for interference fit, but sometimes the outer ring can be a little looser, should be able to make axial swimming in the housing bore bearing seat; when the bearing rings under oscillating load and load is light, can be used than tight fit with a little loose some.
3, the magnitude of load
FAG bearing ring and shaft or housing bore the magnitude of interference depends on the load size, load is heavy, the larger the amount of interference fit; load is light, use a less interference fit. The general radial load P is less than 0.07C at light loads, P greater than 0.07C and less than or equal to 0.15C when the normal load, the P is greater than 0.15C for heavy load ( C bearing dynamic load rating )
