Reason for the bearing chamber wear and maintenance care

Bearing in the process of use, bearing chamber wear or bearing defects and the bearing chamber appeared crack is a common damage state, in order to get the better application to bearing, China bearing network on the basis of experience inform you about the bearing chamber wear the main reason. Of wear of the bearing chamber main reason has the following four kinds: 1, dimension, mainly depends on the machining error of the cause: big local bearing housing and bearing outer ring with common used shaft basis, usually with into smaller clearance fit or transition fit. Once the fit clearance is too large, the bearing outer ring will indoor attacks more frequent rotation in bearing, wear cause bearing chamber. 2, normal metal fatigue wear, fatigue properties of the metal itself has certain, long-term accept vibration will cause metal fatigue normal wear and tear, this phenomenon by resolution metal itself characteristic, so as long as the axis consumption improved during the process of technology extension of metal fatigue cycles, progress using life. 3, smooth oil quality problem: smooth oil content of common use for smooth synthetic oil and petroleum base oil. Smooth oil has certain abrasion resistance, resistance to pressure and viscosity-temperature properties. So inferior smooth oil used in the process of ordinary dryer can not comply with the operation of the high temperature environment, incur smooth oil film rupture or cannot form effective smooth oil film, incur bearings running smooth. Thus bearing friction coefficient is big, in the process of running from inside and outside the circle and outdoor table bearing large torque force, forming the damage of the bearing chamber wear. 4, maintain the improper care: can't timely change bearing or smooth not free and one of the main reason cause the bearing chamber. Bearing housing maintenance care: 1, the use of the bearing chamber cooling system. Bearing chamber under the condition of the correct use of cooling water not only prolong the using life of the bearing, consumption efficiency and progress. Data ordinary bearing chamber are dedicated after disposal of bearing steel made, again good steel bearing chamber also have their use of blame, such as temperature. Bearing chamber in the condition of use, if the mold temperature is too high, it would be easy to make the mold core early appearance presents turtle crack, some bearing chamber that has not yet been beyond 2000 times turtle crack and large area. And bearing in consumption because of bearing high temperature mold core are changed color, after a measure to reach more than four hundred degrees, the temperature meet again in the release agent is easy to appear under the condition of chilling turtle crack, the consumption of products is also easy to deformation, strain, sticky mold etc. The use of the bearing chamber under the condition of the cooling water can greatly reduce the use of release agent, which will help operators application release agent to reduce the temperature of the bearing chamber. The benefits is to effectively extend the service life of bearing seat, thriftiness die casting cycle, yield and quality progress, less viscous modulus and strain, and the status of the glued aluminum attack, reduce the use of release agent. Also can reduce because of bearing temperature through heat and the formation of a plunger and core losses. 2, bearing chamber in the process of beginning consumption required for bearing chamber to stop preheating, avoid suddenly encountered in cold bearing chamber of hot metal to incur turtle crack, more complex bearing chamber can use burner, liquefied gas, die temperature machine, with good condition than simple bearing chamber can slow injection preheating. 3, to the bearing chamber parting surface settlement, it is very convenient, also is very easy to ignore, operators use kerosene in bearing chamber parting surface cleaning thoroughly again, not only can avoid bearing chamber will not be hurt, and after cleaning, can put the bearing chamber on the release agent residue or other vent groove through dirt infarction, is advantageous to the gas discharge in injection mold during the process of yield and quality progress. 4, if the bearing chamber equipped with neutrons control, are wary of the absolute stop between die casting machine and the bearing chamber signal lines have a joint phenomenon, the reason is very understand, in the daily consumption, it is difficult to prevent signal lines touch water, or in the middle of the joint bandage easily broken, thus forming and machine sub, if form error signal, light alarm automatic stop time delay, or signal is disorder, the bearing cap. Don't want to lose. Travel switch attention to waterproof.
