A, tapered bore bearing mounting
Tapered bore bearing can be directly installed in the shaft neck taper, or load locking sleeve and the sleeve of the cone, the coordination degree can be used to measure the bearing radial clearance reduction, therefore, installation should be radial bearing clearance measuring, measuring the clearance should be often needed to achieve clearance reduction so far the installation process, the installation by the lock nut installation, also can use the method of heating installation.
B, thrust bearing installation
The overall thrust bearing and shaft in general for transition fit, with the seat ring and the bearing hole in general are in clearance fit, so that the bearing is easy to install, axial spring of bi-directional thrust bearing should be fixed on the shaft, to prevent relative to the axis. The method of installing SKF bearings, under normal circumstances is mostly rotating shaft, so the inner ring and shaft meet to win the match, with the bearing outer ring and bearing chamber is in clearance fit.
C, a press fit
Bearing inner ring and shaft so that the tight fit, the outer ring and the bearing hole is a loose fit, can press the bearing first pressure mounted on the shaft, and the shaft together with the bearing in the bearing seat hole, pressure mounted in the bearing inner ring on the end face of the assembly sleeve pad, a soft metal ( copper or steel material. The assembly sleeve ), internal diameter should be slightly larger than the shaft diameter, outer diameter should be smaller than the bearing inner ring rib, in order to avoid pressure on holder. Tight fit bearing outer ring and bearing seat hole, the inner ring and shaft is a loose fit, the bearing can be pressed into the bearing hole, when the assembly sleeve diameter should be slightly less than the bore diameter. If the NSK bearings ring and the shaft and hole are tight fit, the installation of indoor ring and the outer ring to press the shaft and hole, the assembly sleeve structure should also face and tight bearing inner and outer ring.
D, heating with
By heating the FAG bearings or bearing seat, the expansion will be a tight fit into installation method matched by heat. It is a common and installation method of labor. This method is suitable for bearing the larger magnitude of interference of the installation, hot charging before the bearing or separable bearing rings into the tank and uniform heating temperature of 80-100 ℃, and then removed from the oil as soon as possible to shaft, in order to prevent the cooling inner end face and shoulder joint is not tight, the bearing cooling can be subjected to axial fastening. The bearing outer ring and light metal bearing seat is tightly matched with heating, bearing the hot charging method, can avoid the mating surface is. Oil tank heating bearings, in the distance at a distance of a mesh, or using a hook hanging bearing, bearing can′t be put in a box bottom, to prevent the heavy impurities into the bearing or uneven heating, the tank must have a thermometer, strictly control the temperature should not exceed 100℃, in order to prevent the occurrence of tempering effect, make the ring hardness decreased.
