Bearing damage and countermeasure diagram analysis

Jiaxing seiko since its inception, technical development, quality and market development has been the focus of attention. Long-term commitment to bearing r&d work and achievement. Bearing under the correct use, can have a long life. If the occurrence of premature damage, it is possible that selection errors, caused by improper use, or bad lubrication. Therefore, when installing a bearing, we need to record the machine type, installation site, the using conditions and the surrounding. Through research summarizes the type of bearing damage, the use of the environment, if a problem occurs in order to avoid similar situation from happening again. Bearing damage way according to the following image classification, we can be judged in the picture shows the main characteristics of the bearing damage forms. Bearing damage pictures and descriptions of understanding, bearing damage so we need what countermeasures to deal with? Here we use a chart to quick, accurate, concise analysis problem causes and solutions, so that in the process of application will be helpful to you. Project after its running surface stripping phenomenon reason measures show obvious convex concave shape, the load is too large or improper use, installation of bad, shaft bearing box bad precision, clearance is too small, foreign invasion, occurrence rust, caused by abnormal high temperature hardness drop, to research conditions of use, to select bearing, reconsider clearance, check the shaft and bearing box processing precision, study around the bearing design, check the installation method, check the lubricant and lubricating bearing heating method burns becomes angry, and then burn can not rotate, clearance is too small ( Including the deformation part clearance is too small) , insufficient lubrication or improper lubricant, overload, Preloading is too big) , roller deflection, set appropriate clearance ( Increase the clearance) Check, check the lubricant types to ensure injection, use condition, prevent the positioning error, check the bearing design (around Including bearing heat) Crack defects, improve the bearing assembly method part gap and crack, impact load is too large, interference is too large, have greater detachment, the lateral friction crack, the installation precision is bad ( Round the corner too • use the bad ( Copper hammer, card into the big foreign body) , check the conditions of use, set the appropriate interference and check material, improve the installation and use, to prevent the crack of friction ( Check the lubricant) , check the bearing looseness or breakage design cage around damaged rivet maintains a rupture, excessive torque load, high speed or speed change frequently, poor lubrication, card into a foreign body, vibration, installation bad ( Installation tilt condition) Abnormal temperature rise ( Resin cage) , check the conditions of use, check the lubrication conditions, to study the choice of the cage, pay attention to the bearing use, the shaft and the bearing box rigid scratch card wound surface is rough, with tiny soluble apply ring gear edge and the end of the roller scratch injury, poor lubrication, foreign invasion, called card bearing tilt caused by roller deflection, axial load caused by the big guard broken oil, rough surface large, rolling body sliding again big, the lubricant, lubrication method, check the conditions of use, set appropriate preloading, improved sealing performance, part or all of normal use bearing rust corrosion rust pitch roller with rust, bad condition of storage, improper packing, rust inhibitor is insufficient, moisture, acid solution such as intrusion, bearing directly with the hand, to prevent the safekeeping of rust, improved sealing performance, regular inspection, pay attention to the bearing lubricating oil use mating surface produce red rust, abrasive wear powder, a surplus quantity is not enough, bearing shake Angle smaller, less lubrication ( Or no lubrication state) Vibration, the stability of the load, transit, to check interference and lubricant coating state, when transported separately on inner and outer packing, not separate when they exerted pressure, to select lubricant, reselect bearing wear surface wear, cause size change, accompanied by gall, grinding crack, lubricant in the mixed into the foreign body, poor lubrication, roller deflection, check the lubricants and lubrication method, improved sealing performance, prevent the positioning error electric erosion rolling surface shape pit of the crater, the further development in wave plate, rolling surface electricity, making current bypass valve, insulation measures, avoid the current through the bearing internal creasing card into the solid foreign bodies and bruised or pits of the impact surface and installation yes bruises, solid foreign invasion, card into the stripping piece, install the adverse impact caused by the loss, in the condition of inclined installation, improve the installation and use methods, to prevent foreign body with, if caused by metal, must check the other parts of the creep inside or outside sliding, mirror or discoloration, sometimes get stuck, insufficient amount of interference fit place, tighten enough sleeve, abnormal temperature rise, study load is too large, to study the interference quantity, conditions of use, check the shaft and bearing box of jiaxing seiko precision co. , LTD.
