Koyo double LieDiao heart ball bearings and the shaft shoulder lubrication method to use

In general, the tight fit interference installed double LieDiao heart ball 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. Test, the bearing inner ring end face and shoulder on the circumference of a circle to try several, and if found to have clearance is very uniform, koyo bearing is not installed in place, inflating a double ball bearing inner ring LieDiao heart make it depends on tight 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. Koyo bearing lubrication in principle with other double LieDiao heart ball bearing lubrication is consistent, only bearing working condition is bad, its performance could get effective play to a large extent depends on the situation of the lubrication of the bearing. Bearing lubrication methods mainly include grease lubrication and oil lubrication. Grease lubrication grease and seal, seal structure and lubrication equipment simple, add grease is convenient, so as long as the work conditions allow, koyo bearings are generally used grease lubrication. Oil lubrication cooling effect is strong, and can be taken from bearing inner dirt and moisture. Double LieDiao heart ball bearing lubrication oil lubrication methods have pressure oil lubrication and oil lubrication, oil mist lubrication and oil lubrication. Under the pressure oil lubrication is normal speed koyo bearing is the most effective way of lubrication. Oil lubrication is the lubricating oil at a certain pressure through in a bearing on one side of the nozzle spray into the double LieDiao heart internal lubrication for ball bearing, commonly used in the high-speed bearing, or pressure oil supply lubrication can't satisfy the cooling requirements of the occasion. Spray lubrication is to contain oil mist dry compressed air into the double LieDiao heart internal lubrication for ball bearing, use less oil, due to the effect of air, cooling effect is extremely strong, it is mainly used for high speed and high precision of rolling large koyo bearing, or to often do not remove the bearing in the bearing housing. If koyo bearings for interference fit is mounted on the bearing hole, double LieDiao heart ball 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.
