Koyo bearing installed with detection technology

Rolling bearing and the shaft's joint venture for the transition of the joint venture, seat and bearing hole of the joint venture for the clearance of the joint venture. The center axis of the two-way bearing ring should be fixed on the shaft, in order to avoid related to migration of axis shift. Koyo bearing device, a popular condition is the condition of shaft changes in the majority, and inner ring and the shaft joint venture for win, bearing outer ring and the bearing chamber of the joint venture for the clearance of the joint venture. Device for rolling bearing, to fix the dial gauge box shell end face, make the table touch the top of the head in the bearing axis shift bearing ring raceway on migration, migration transformation while see dial gauge pointer, if the deflection of the pointer, clarify among axis and axis line not vertical. If the box shell hole deep, also can use extended dial gauge head hone. This is a very good hone shaft circle and axis perpendicularity of the median line method. The wrong Koyo bearing device, not only operation of the bearing and the joint venture will face badly worn. Because the circle with the seat and the difference is not obvious, the assembly of cockiness special be careful, can't appear upside. Device accurate time should be when the seat can take the initiative to adapt to the roller rolling, to ensure that is located in the upper and lower roller ring raceway. In addition, self-aligning ball bearing seat and bearing holes should also be left between 0. 2 - 0. 5 mm gap to compensate the error in the composition of the defective parts processing, installation, when the bearing ring in the middle shift operation, the clearance can ensure that its active adjustment, the avoidance of friction, make its normal operation. Otherwise, will make serious damage of the bearing. Test 1, the feet of common types: rolling bearing of rolling mill bearing, joint bearings, wheel bearings, insert ball bearing, thrust ball bearings, one-way bearing, full roller bearings, thrust roller bearings, linear motion bearings. For larger diameter rolling bearing, the gap is larger, with a narrow feeler direct detection. For small diameter, Koyo bearing clearance is small, inconvenience with feeler, bearing clearance, however, must use the thickness of the appropriate feeler. 2, pressure lead test by pressing lead was detected using feeler, accurately detect rolling bearing clearance but more trouble. Aluminium wire used in the test should be soft, shoulds not be too big or too small in diameter, the diameter of the ideal of clearance of 1. 5 ~ 2 times, the actual work showed soft lead wire for testing. Detection, first open the Koyo bearing cover, the diameter of the lead wire, appropriate to cut it into 15 ~ 40 mm long segments, on the shaft neck and upper and lower bearing interface, cover the bearing cover, tighten the retaining bolt torque by the regulation, unscrew the bolt, then remove the bearing cover, micrometer is used to inspect flattening lead wire thickness, and the average of the top bearing clearance. If the top gap is too small, can add pad on the surface of the upper and lower tile combination. If too large, the reduction of pad, scraping the inquiry or watering the tile again. Koyo bearings after installation, in order to check whether installed correctly, check for running. Small mechanical can rotate with the hand, to confirm whether to rotate smoothly. Check project has caused by foreign bodies, scars, creasing seized up, due to bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction caused by the torque is too big, and so on. If there is no abnormal can start power operation.
