For as long as possible in order to adhere to bearing the function of the original outstanding condition, maintenance, repair, in order to prevent accident arrangement, to ensure reliability of the work, improve the productivity and economy.Curing the best corresponding mechanical working conditions of specification, timing.Content includes sliding bearing monitoring working condition, make up or replace smooth agent, view of time apart.As a work of maintenance matters, have bearing rotating the sound, vibration, temperature, the condition of smooth agent and so on.
Bearing cleaning: open bearing maintenance, the appearance of the first recorded bearing, confirm the residual stock composite bearing smooth agent, after sampling check with smooth agent, washing bearing.As a cleaner, usually use gasoline, kerosene.
Tear open come down to the bearing cleaning, coarse and fine clean clean, separation on the container, first put on the metal mesh at the bottom of the bearing is not straight touch touch dirt from the container.Coarse clean, if the bearing with dirt, can damage the bearing surface, should be pay attention.In coarse clean oil, use a brush to remove to smooth grease, adhesive, after clean, roughly into fine cleaning).
Fine cleaning, bearing in the clean oil side spin, carefully clean.Other, clean the oil also will always adhere to the clean.{TodayHot}
Bearing maintenance and judgment: in order to figure out whether open down bearing can use, to check in the bearing after washing clean.View the raceway surface on the surface of the roll surface, cooperation, adhere to the wear condition, bearing clearance, and has nothing to do with scale precision falling damage, abnormal.Non separation of small ball bearing, the inner ring with one hand support levels, rotate the outer ring to confirm whether smooth.
Tapered roller bearing type bearing separation, able to roll body, the outer ring raceway surface view separation.
Because of large bearing not rotate with the hand, pay attention to check the roll body, raceway surface, insist on the frame, guard surface appearance, such as the importance of bearing high stable must see.
Bearing the intention of the smooth:
Smooth intent is to cut the bearing of the rolling bearing internal conflict and friction losses, smooth to avoid burning stick, its utility is as follows.{HotTag}
(1), reduce conflict and friction losses.
In the form of bearing ring, rolling body and stick to touch each other some, avoid touching, metal cutting conflict, wear and tear.
(2), the extension of fatigue life spans.
Bearing rolling fatigue become old, yea, in the rotation, the rolling touch surface is smooth, the outstanding is outspread.On the contrary, low oil viscosity, smooth and oil film thickness owe good, is shortened.
(3), heat, cooling discharge conflict.
Cycle to oil can oil discharge caused by the conflict, such as heat, or by external heat from the cooling.Avoid overheating bearing, smooth oil itself.
(4), other
Also has to avoid foreign body into bearing internal, or avoid the effect of rust and corrosion.Smooth way:
Measures for the smooth of bearing is divided into oil and grease smooth smooth.In order to make the function of bearing performance extremely well, first, to choose appropriate conditions, the intention of using the smooth way.If only consider smooth, the oil slick smoothness is preferred.But can simplify the one fat smooth around the bearing structure specialty, will be fat and oil slick smooth interest contrast.
The bearing device:
Bearing device is accurate, affects the precision, stature, function.Therefore, design and assembly parts of the bearing's device to full discussion.Expect to carried out in accordance with the working rules on the device.Job specification project usually is as follows:
(1), clean bearing and the bearing connection parts;
(2), check the scale of the hook part and finishing condition;
(3), device;
(4), the device after good bearing view;
(5), smooth supply agent.
At least in front of the line device, just open the bearing packing.Usually smooth smooth, not clean, smooth filling grease directly.Oil smooth smooth, usually don't have to clean, however, instrument using or high speed bearings, etc., to wash with clean oil, remove rust inhibitor) on the bearing.Remove the rust inhibitor of bearing, easy to rust, so can't place.Moreover, has smooth sealed bearing grease, not clean direct use.
Bearing device, owing to the different bearing structure, cooperation, conditions, usually, because more as the axis of rotation, so the inner ring needs cooperation can be made.Cylindrical hole bearing, multi-purpose press pressure into, or multi-purpose hot charging method.Taper hole, device on the taper shaft directly, or use the sleeve device.
Unit to the case, we usually clearance cooperation, outer ring had surplus quantity, usually with press pressure, or have after cooling device of cold working methods.Use dry ice as coolant, cold working device, the moisture in the air condenses on the surface of bearing.So, demand of appropriate anticorrosive measures.
