Jiaxing bearing small make up for you introduce test of rolling bearing and the shaft shoulder depend on the degree of tight

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. In general, the tight fit interference installation of rolling bearings must rely on the shoulder. Inspection methods are as follows: ( 1) Lighting method. The lights on the bearing and shaft shoulders, see light-leaking judging. If not light-leaking, installed correctly; If uniform around the shoulder light-leaking, bearing with shoulder to rely on tight, deal with bearing put pressure on tight; If some light-leaking, bearing installation tilt, available hit bearing inner ring hammer, tongbang, or socket, trued slowly. （ 2) Thickness gauge test. The thickness of the thickness gauge shall be 0. 3 mm. Test, the bearing inner ring end face and shoulder the entire circumference try several, and if found to have clearance is very uniform, bearing is not installed in place, inflating a bearing inner ring to make it on the shoulder; If increase the pressure also is not tight, journal fillet area of rounded corners is too large, the bearing stuck, should trim journal fillet, make its become smaller; If it is found that bearing inner ring end face and bearing shoulder parts thickness gauge can pass, that at this time must be removed, to nap, reinstall. If bearing for interference fit is mounted on the bearing hole, bearing outer ring is fixed, shell hole block shoulder its outer end face and the shell hole blocking shoulder face is on tight, installation is correct, also can examine thickness gauge. When installing thrust bearing thrust bearing test after the installation, should check shaft and shaft centerline of verticality. Method is to fix the dial gauge box shell end face, make the table touch the top of the head of the ring raceway on bearing axle bearing, and observe the dial gauge pointer, if the pointer deflection, axial circle and not vertical shaft centerline. Box shell hole deep, also can use extended dial gauge head test. Thrust bearing installed correctly, the seat can automatically adapt to roller rolling, to ensure that the rolling elements located at the top and bottom ring raceway. If installed backwards, bearing not only don't work properly, and the matching surface will badly worn. Due to the difference between the shaft ring and seat is not very obvious, the assembly should be extra careful, do not make a mistake. In addition, the seat of thrust bearing and the bearing holes should also be left between 0. 20. 5 mm clearance to compensate parts processing, installation error caused by inaccurate, when the bearing ring during operation center offset, the clearance can be adjusted to ensure the automatic, the avoidance of friction, make its normal operation. Otherwise, will cause bearing severe damage. If you are more interested in jiaxing bearing group co. , LTD.
