The cooperation gap between KOYO bearing and shaft must be suitable; in order to make the service life of KOYO bearing last longer; the following method can be used to detect the radial clearance of KOYO bearing:
First, the ruler detection method on the KOYO bearing with larger diameter; the gap is larger; it is intended to be directly detected with a narrow feeler gauge. About the KOYO bearing with smaller diameter; the gap is smaller. The prize is é˜Œ åŸé¥¬æµš åŸé¥¬æµš bad side of the KOYO bearing Gap; must be measured with a suitable thickness gauge.
Second, the lead-pressure detection method using the lead-pressure method to detect KOYO bearing voids is more accurate than using the feeler gauge; but it is more complicated. The aluminum wire used for testing should be soft; the diameter is moderate; not too big or too. Noisy this paragraph æ¹ŽPocket 1. 5~2 times; in practice, soft lead wire is usually used for testing.
The time of detection; first open the KOYO bearing cover; select the appropriate diameter of the lead wire; cut it into 15~40 mm long section; place it on the journal and the upper and lower KOYO bearing interface; cover the KOYO bearing cover; Tighten the fixing bolts; then loosen the bolts; remove the KOYO bearing cap; use a micrometer to measure the thickness of the flattened wire; and find the average value of the KOYO bearing top clearance.
If the headspace is too. Slightly thin (11) å³¦å‘“å²· å«” å«” . .. If too large; then reduce the pad, scrape the ground or cast the tile from the head.
Adjustment of bearing bushing force: In order to avoid possible transition and axial movement of the bearing bush during operation; in addition to cooperating with interference and stop parts; bearing bush must also be pressed with KOYO bearing cap; measuring method and measuring top gap method The same; the thickness of the soft lead wire is measured; the bearing bushing force can be calculated.
Usually, the bearing force of the bearing bush is between 0. 02 and 0. 04 mm. If the pressing force does not meet the specifications, it can be adjusted by increasing or decreasing the thickness of the gasket at the joint surface of KOYO bearing and KOYO bearing seat; the back of the tile is not allowed to be padded. .
In addition to ensuring radial clearance, sliding KOYO bearings should also ensure axial clearance. When detecting axial clearances; move the shaft to a pole orientation; then use a feeler gauge or dial gauge to measure the axis from one pole to the other. The azimuth turbulence is the axial clearance. When the gap of the sliding KOYO bearing does not meet the rules; adjustment should be made. The split KOYO bearing often uses a gasket to adjust the radial clearance.
