Bearing manufacturer to tell you the cause of bearing damage

Bearing manufacturer to tell you the cause of damage of bearing roller bearing, if there is no wrong choice can be used correctly, until the bearing life, can use for a long time, in this case, the damage status to divest. On the other hand, there are unexpected injury earlier, and yield to the early damage of use, as the reasons of early damage, not enough to use scare the consideration on the lubrication and, in turn, and foreign invasion, the error of the bearing assembly and axis deflection of big, not enough research on shaft and bearing box, etc. It can be said that these reasons the situation more overlap each other. So, want to use machine to fully understand the bearing, conditions of use, bearing outer structure based on, if we can find out before and after the accident situation, again according to the damage of the bearing and a variety of reasons, can prevent the similar accidents from happening again. Bearing manufacturer for instance! Stripping spending damage status: when bearing load bearing rotation again, inner ring and outer ring raceway surface or rolling decent present designed stripping due to rolling fatigue phenomenon. Too much spending reasons: s load s bad installation ( Non linear) S torque load s foreign invasion, the water s poor lubrication, lubricants inappropriate inappropriate s bearing box s bearing clearance accuracy is bad, uneven rigidity of bearing box s axis deflection of great bustard rust, erosion point, scratch and indentation ( The surface deformation phenomenon) Cause the development of spending measures: s check the size of load and used again bearing s improve installation method s to improve the sealing device, when stop rust s using the appropriate lubricant viscosity, improving the lubrication method s check the shaft and the accuracy of bearing box s check clearance card spending injury damage status: the so-called card is produced in the slip surface injury injury minor burns summary of part of the surface damage. Slide face, rolling surface circumferential direction of linear scars. End of the roller set linear scar near the end of the roller shaft torus card. Excessive spending reasons: s too much load and poor lubrication preloading s s foreign body nip s inner ring of the outer ring tilt, the deflection of shaft s axis and the precision of bearing box bad spending measures: s check load size s preloading to appropriate s check the shaft s improved lubricants and lubrication method, the accuracy of bearing box bruises spending damage status: the so-called bruises, is the raceway surface and rolling consult personally again, with rolling slippage and the small burns the sum of the oil film cracking occurring in the course of surface damage. Rough surface with a stick. Spending reasons: s high speed light load s sharp deceleration s lubricant inadequate s water intrusion spending measures: s improved preloading s bearing clearance s use lubricant with good sex of the oil film s improving lubrication method s spending to improve sealing device fracture damage status: fracture refers to the roller Angle of raceway on the wheel rim or local part are exerted impact or excessive load and a small part of the fracture. Spending reasons: s is shocked when installation s load falling too s using bad spending measures such as: s improve installation method ( Adopt the hot charging, using the appropriate tool holder) S bearing installed, s correct load conditions make the guard by supporting the indentation spending damage status: bite into a tiny metal powder, foreign bodies, such as on the raceway surface or rotating the dent. Due to impact, such as installation on the roller spacing interval to form the concave ( Brinell hardness indentation) 。 Spending reasons: s of metal powder and other foreign body nip s assembly or transport process under impact load is too large spending measures: s shock collar s improved filter sealing device s lubricating oil s assembly and usage state of burn injury of spending: race, rolling element and cage in the rotating heat until discolored sharply, softening, deposition and damaged. Spending reasons: s s too big load (poor lubrication Preloading is too big) S too much speed s clearance is too small s water intrusion, foreign body. S axis, the accuracy of bearing box, axis deflection of big spending measures: s research on the choice of lubricants and lubrication method s correct bearing s research, bearing clearance and preloading s to improve the precision of the sealing device s check the shaft and bearing box s improve rust installation method, the spending of corrosion damage status: bearing rust and corrosion groove wheel, rolling on the surface of the body surface rust pit type, comprehensive rust and corrosion. Spending reasons: s water, corrosive substances ( Paint, gas, etc. ) Inappropriate invade s lubricant s due to the condensation of water vapor with high temperature water s wet when more stalling s transport heavy rust bad s utilization status, inappropriate s inappropriate spending measures: s improving lubrication sealing device s research method s anti-rust measures when the stalling s improve utilization method s [to be paid attention to when Return] A: what kind of precision ball forming method are there?
