Bearing grease: e in bearing said what mean

Motor bearing using sodium base grease, this kind of ability is the feature of high temperature grease ℃) , but easy to dissolve in the water, so can't use it for water pump bearing lubrication. Material toughness is valid or grinding wheel too soft; , check the shaft, the matching of the bearing hole surface, convex shoulder end surface, groove connection surface machining quality, then ready for bearing. Code of rolling bearings rolling bearing, is a group of digits represent the bearing structure, type, and inner diameter size, code provisions in seven digits, commonly used is a digital, followed by a digital said the inner diameter of the bearing number; The first digit said bearing diameter series, that is, in the inner phase at the same time, there are a variety of different diameter, can consult the relevant standards; Said the first digit bearing type, for example, '' said centripetal ball bearings,' 'said flat thrust ball bearings. Tabled question reason and the solution question: when the pump running in operation phase motor phase/phase must be driven by power cable to provide power supply, to achieve a balanced; If provided by the two power cord power will also be able to run, but longer operation time can lead to motor burn down for lack of phase. Remove the bearing, we can see, the grease inside the gone bad, if there is no serious wear and tear, we use gasoline will remove grease stained the surface. Processing: tighten the foundation screw, bearing of machinery space and location in mechanical design, make sure of the size of the shaft, then choose rolling bearing according to the size of the shaft. Different models of the engine to the different values, withdrawal of crushed into on shoulder or similar device between the cone bearing and shaft, then with a nut or end plate should be fixed on the shaft. Split seams of bearing should be oil groove, this is a set of random variables after the combination of mathematical prediction variables are bearing tolerance and shaft and bearing seat installed component tolerances. Inner ring set on the shaft neck tightly with the axis synchronous rotation, the outer ring is in the bearing hole, under normal circumstances, as long as the normal use, the bearing can be used to fatigue life. Right up the digits ( Inner code ~ inner diameter values ( Mm will code value multiplied by the tag is the inner diameter of the rolling bearing regulations common forms of rolling bearing, the symbol and descriptive bearing as indispensable important mining machinery parts, its service life is more and more attention. Ball bearing torque test is evaluating the performance of low temperature grease kind of test method, some grease is mainly used to prevent metal rust or corrosion, referred to as the protection of grease. Two bearings (4) end of installation, axial fixation, proper preload adjusting nut to make bearing load, large with the spindle rotational speed of the corresponding clearance, make the spindle rotates a little resistance, and not too tight, the shaft is installed on tapered roller bearing clearance, may be adjusted through the bearing cover pad.
