IKO forklift bearing clearance and the clearance of the importance of lubrication - bearing knowledge
Bearing rotates, as IKO bearing rotating speed, bearing the internal friction heat and the temperature rise is also increased.
Rotational speed limit is able to produce sintering, overheating, running speed value of experience.
Should this, all kinds of bearing limit speed, due to the bearing structure, size, cage structure, material, bearing load, lubrication methods, including bearing cooling conditions and different.
Forklift bearing clearance namely bearing in the bearing box mounted on shafts or not, will it a fixed housing, then the party has not been fixed do radial or axial movement of the mobile.
According to the moving direction, can be divided into radial clearance and axial clearance.
The size of the clearance of IKO bearing in the operation of the rolling fatigue life, temperature, noise, vibration, etc.
Measurement of bearing clearance, to obtain stable measured value, generally impose regulations on bearing load measurement.
Received as a result, the measured value is bigger than real clearance, which increases the measuring load produced by the elastic deformation.
But for bearings of the roller bearing, due to the elastic deformation is small, can be neglected.
Before the installation of bearing internal clearance is generally expressed in the theory of clearance.
Forklift bearing lubrication is the use of the rolling surface of relative movement between oil film will be separated from each other, not excessive wear and failure as a result of rough contacts.
If users can attach great importance to IKO bearing lubrication technology, can ensure that during the working life of the rules, still can maintain the stable performance and rotation accuracy.
Bearing lubrication grease lubrication and oil lubrication, grease lubrication facilities of the method is simple, the grease is not easy to leak, have certain waterproof, gas and other impurities into the IKO bearing ability, therefore usually grease lubrication is widely used.
Such as overloading, high speed, high temperature working condition of oil lubrication.
Grease is composed of base oil, thickener and add agent.
Base oil viscosity play an important role on the lubrication performance of the grease, the thickener composition on the performance of the fat, especially the temperature characteristic, water resistance, oil analysis, etc have important influence on, add agent is mainly used to enhance the resistance of gasification of the grease, rust, extreme pressure performance, etc.
According to the types of lubricants, the brand is different, there are other performance is good, but not suitable for high speed rotation.
So, IKO bearing rotating faster than bearing the limit speed of 70% recorded in the table size, need to choose the excellent performance of grease, lubricating oil.
Forklift bearings of various sizes in the table, according to each IKO bearing all records the limit speed of grease lubrication and oil lubrication.
This value is the standard design of bearing, under the condition of normal load, grease lubrication and oil lubrication operation, allowed by the rotation of the number.
The value of oil lubrication, which is based on oil bath lubrication benchmark.
