One, bearing in the process of running, sometimes into foreign IKO bearing surface between hard particles or hard foreign body or abrasive dust on the surface of the metal, it can cause furrow is bearing abrasion, inside these hard foreign body through into the bearing lubrication medium, with the continuous operation of bearing, the local friction heat production, easy to cause the friction surface phenomena, local micro welding deformation and friction of partial melting may even happen, finally cause occlusion phenomenon.
Two, bearing faults have defects and overload causes two factors, when fracture loads more than material strength limit and cause parts called overload fracture, overheating in IKO bearings can also occur during the operation of organizations and local burns and other defects, defect caused by fracture.
From the point of use should pay attention to the following: 1, bearing type selection, bearing type are generally according to the product of form a complete set of conditions of use and the load of IKO bearing selection.
So you have to learn the user's actual load is consistent with the selected bearing, if bearing can not meet the use requirements, should change model as soon as possible, but unless special products on the choice models generally do not have what problem.
2, the selection of the bearing clearance: when buying bearings generally just let us know in what type, grade, rarely for IKO bearing clearance request, business people must ask bearing conditions of use, which the bearing rotating speed, temperature, tolerance is directly related to the selection of the bearing clearance.
Generally under 3500 RPM speed motor mostly adopts CM clearance, such as high temperature and high speed motor, require the use of relatively large clearance.
Bearing clearance after assembly will rise because of the inner hole and cylindrical reduction and lead to reduce, the reduction of clearance = interference quantity x 60% (
Except the bearing chamber is aluminum)
。
Such as bearing clearance is zero before assembly.
01 mm, interference when assembling the quantity to zero.
01 mm, bearing assembly after the clearance of 0.
004mm。
In theory at zero clearance noise and bearing life can reach the best state, but in actual operation considering the problems such as temperature, bearing clearance to 0 after assembly.
002mm-
0.
004 mm is better.
3, the choice of grease: the choice of grease are generally according to the situation of IKO bearing rotating speed, heat resistance, noise, requirement and select starting torque, etc, for the performance of various oil is very understanding.
4, the choice of bearing seal type: IKO bearing lubrication can be divided into oil lubrication and grease lubrication.
Oil lubricated bearing is generally choose form of bearing, grease lubricated bearing dust cover is generally selected or rubber seal seal.
Dust cover suitable for high temperature or the use of good parts, seal two points contact seal and non-contact seal and contact seal dustproof performance is good but the starting torque, the sealing type starting torque is small, but there is no contact sealing performance is good.
