KOYO one-way bearing and the degree of the shoulder on tight

In general, the interference fit to install the one-way bearings must rely on shoulder. Test method: 1) Lighting method. The lights on, KOYO bearings and shaft shoulders look 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. Inspection, the one-way bearing inner ring end face and shoulder the entire circumference try several, and if found to have clearance is very uniform, KOYO 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, not at this time must be removed, to nap, reinstall. If KOYO bearings for interference fit is mounted on the bearing hole, a one-way 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. Bearing inspection when installing KOYO bearings after installation, should check shaft circle and verticality of shaft centerline. Method is to fix the dial gauge box shell end face, make the table touch the top of the head in a unidirectional ring raceway on bearing axle bearing, and observe the dial gauge pointer, if the deflection of the pointer, shaft ring and shaft centerline is not vertical. Box shell hole deep, also can use extended dial gauge head test. One-way 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 axial ring and seat and the difference is not obvious, the assembly should be extra careful, do not make a mistake. In addition, KOYO bearing seat and the bearing hole there should also be between 0. 2 - 0. 5 mm clearance to compensate parts processing, installation error caused by inaccurate, when one-way bearing ring during operation center migration, the clearance can be adjusted to ensure the automatic, the avoidance of friction, make its normal operation. Otherwise, will cause the KOYO bearing severe damage.
