INA even pump shaft bearing axial clearance adjustment must pay attention to the point

Is the life of the bearing with maintenance and maintenance has a very important relationship, because it is related to the length of the water pump shaft bearing life even, high and low working efficiency. Maintenance the INA bearing, good use can bring many benefits, such as can lead to high production efficiency, produce higher quality precision products several times maintenance can prolong life save you time to purchasing cost. 1 adjusting shim method: in the bearing cover and bearing seat face between placing a set of soft materials ( Mild steel or elastic paper) Gasket; When adjustment, not first spacer on the pump shaft bearing end cover, a evenly tighten the screw on the bearing end cover, a rotation shaft with the hand, until the rolling element bearing contact with the outer ring and axial internal clearance so far; When measuring the bearing cover and bearing gap between end face, plus the INA bearing the axial clearance in normal work need; This is required to fill in spacer thickness, and then fill in the bearing cover and gasket prepared between bearing end face, finally tighten the screws. 2 adjusting bolt method: press the circle on the bearing's outer ring, pressurized with adjusting bolts; Before the pressure adjustment, first of all to measure adjustment bolt pitch, then adjust the bolt tightening slowly, until the bearing internal no clearance, and then calculate the adjustment bolt corresponding rotation Angle. For example, pitch to 1. 5 mm, water pump shaft bearing clearance required for normal operation, then adjust the bolt required rotation Angle of 3600 * 0. 15／l. 5 = 360; At this time the adjustment bolt reverse 360, INA bearings was 0. 5 mm axial clearance, and then use gaskets to be fixed can stop. Flow is lubricated by grease bearing should be replaced after running 1500 hours, grease filling amount of oil in moderation, because grease too much or too little will cause the water pump shaft bearing heating, amount to general in bearing chamber volume 1/2 ~ 2/3 is advisable. However, for INA bearings used lubricating oil, oil should be added to the location of the corresponding provisions;
