Imported bearing installed directly affects the performance and service life - bearing knowledge
Bearing is one of the important parts on construction machinery, poor installation will affect its use effect, even result in engineering machinery and equipment failure.
If the imported bearing with iron filings, burrs, dirt and other foreign matter to enter, will make the import bearing noise and vibration during operation, and even damage raceway and the moving body.
So before the installation of bearings, it is necessary to ensure that the installation surface and the environment clean.
In order to make the imported bearing a good cast performance, first of all, should choose to suit to use premise, purpose of lubrication method.
In addition, the increase of vibration and friction could significantly increase the risk of energy consumption and premature failure.
The method of bearing lubrication, divided into grease lubrication and oil lubrication.
Thickener and relationship with lubrication function, thickening agent of water resistance to the water resistance of the grease.
Lubrication of the bearing work and life have very important influence.
The whole block imports bearing not clean fuel.
Imported bearing surface coated with anti-rust oil, it is necessary to use of clean gasoline or kerosene cleaning carefully, then coated with clean, high quality or high speed high temperature lubricating grease before installation.
The function of the grease is mainly composed of base oil.
In principle, different brand of grease can't mix, and even the same thickening agent of grease, will also bring bad influence each other on the basis of different additives.
Grease made out of base oil, thickener and additive.
The basis of generally low viscosity oil used in low temperature, high speed;
Used for high temperature, high load of high viscosity.
After the imported bearing installed, if not done carefully alignment, alignment can lead to bearing suffered another load, friction, and vibration.
These could accelerate fatigue and reduce the use of bearing life, and it might damage the other machine parts service life.
Hydraulic pump plunger pump bearing is the most important components of the bearing.
Reduce the negative pressure in the imported bearing is to prevent the water into the basic requirements.
Angular contact bearing load calculation.
Oil for maintenance of locomotive bearing is very important.
In the process of operation, import bearing requires accurate lubrication again, perfect its performance.
The regular check to early detection of latent subject and will prevent unexpected machine suspended on the phenomenon, make production plan, the progress of factory production force and efficiency.
If only consider lubrication and oil lubrication the lubricity of the upper hand.
But there are grease lubrication can simplify the structure of imported bearing near specialty.
