We should pay attention to the following points: one, from the angle of use to ensure the stable operation:
1, appropriate clearance, impact is too large, too small, poor lubrication, may burn tile.
2, the rolling bearing and shaft neck surface quality and geometry should be strictly guaranteed.
3, improve the quality of lubrication, control oil pressure, temperature and flow, strengthening the oil filter.
The temperature status 4, control of diesel engine, the overheating too cold circumstances are bad. Cold weather, diesel engine preheating before starting, and rotate the crankshaft by hand so that the oil into the
5, with fuel oil and lubricating oil regulations.
Two, to extend the three principles of IKO bearings
A. IKO bearing type high load capacity
Bearing selection should take into account the bearing of the price, or the higher load capacity but more expensive rolling bearing, or on the use of ordinary while trying to extend its life. The bearings have a high load capacity, for example with cylinder roller bearing convexity bearing spherical roller symmetric roller, belt, strengthen the tapered roller and ball type ball groove bus modified ball, or IKO bearing 70000CD series of deep groove ball instead (radial), these have a high load capacity of the bearing or because of improving the stress distribution, fatigue or because of rolling body and may have a higher number of.
B. select the size of bearing right
To make the size is rightly chosen, must work load, accurate computation and calculation of rolling bearing speed and operating temperature. Effect of load on the maximum lifetime, so the load while most difficult to measure but also should be measured accurately. When there are difficulties load measurement, can measure the actual power consumption is calculated according to the motor, transmission routes and deduct the losses along the process for power, until the calculated is closer to the actual load. Load calculated or measured is too large, the fatigue life of IKO bearings can expect inevitable with greater amplitude decreases, must try to remedy. If the installation position is allowed, bearing products optional size file; if the radial size is limited, the rolling bearing in the presence of a wide bearing conditions should be wide; if cannot use bearing wide, can use the load bearing capacity of high.
C. to select suitable materials
The choice of rolling bearing materials should take into account its price, and when to use vacuum melting and electroslag remelting steel, attention should be paid to the lubrication conditions must be perfect, can greatly improve the fatigue life can be expected. Of course, this kind of selection of high quality steel bearing costs than the selection of bearing load capacity is higher much more expensive, but in the machine is difficult to close and very difficult to assemble and disassemble, or mine, tunnel operation machinery used in the IKO bearings, maintenance is very difficult situations, sometimes must still consider the use of.
