Different types and different sizes of bearings, installation methods and tools are also varied, with mechanical or hydraulic. Here is mainly to explain some common basic installation methods and considerations.
Do not install on the ball, which can cause local overload of ball and the contact surface, leading to premature failure of FAG bearings.
Do not use solid tools, such as hammers, screwdrivers and the like knock bearing surface, which would allow the fracture or cracking of the outer ring of the bearing.
Bearing cleaner
Clean environment is important for bearings. Bearing ring turning and rolling elements of precision surface roughness is probably one-tenth μ m, smooth surface of the ball if contaminated, the impact is very serious. Rolling lubrication between the surface layer is typically a 0.2~1 μ m, size is greater than the lubricant particles of impurities will be subject to excessive rolling of rolling elements in self-aligning roller bearing steel in the partial pressure, will eventually lead to permanent fatigue. In addition to this, the external environment of dust particles in sizes up to 10 μ m, will also reverse heart roller bearings are damaged. That is why, bearing process detection
Thermal induction in use by the operating temperature of the bearing, if temperatures exceed the established limit, then automatically alert, to prevent the occurrence of hot box. High temperature often indicates that the bearing is in unusual circumstances. High temperature but is also harmful to the bearing lubricant. Sometimes overheated bearings can retain the lubricant in the bearing. If the bearing temperature exceeds 125 ℃ long-term continuous transfers reduce the service life of the bearing. Causes of high temperature bearings including: insufficient bearing lubrication lubricant may not be qualified, which contain impurities, when under heavy load may also be FAG bearing internal clearance not enough friction the oil seal, and so on.
Bearings are properly installed, affecting the accuracy, longevity, performance. Therefore, design for bearing installation and Assembly sector to fully study. Want to be installed in accordance with the standard. Standard project typically is as follows:
(1) check the size and finishing of associated parts;
(2) installation;
(3) supply of lubricants.
(4) clean bearing and associated parts;
(5) bearing after installation check;
Want to just before installing, just open the bearing packing. Are lubricated by lubricating oil, ordinary or cleaning, however, instruments or high speed bearings, to wash with clean oil, dropping the antirust coating on the bearing. General grease lubrication, no cleaning, fill the grease directly. Furthermore, into the bearings with grease, no cleaning directly. Remove Rust of bearings, rusted, so cannot be placed aside.
When installed into the shell, General clearance and interference in the outer ring, usually press onto, or cooling installation of shrink fit method. Use dry ice as a cooling agent, shrink fit occasion, moisture in the air will condense on the bearing surface. Therefore, appropriate measures against corrosion.
Bearing installation methods, fit, the bearing structure varies depending on the conditions, in General, due to rotate, so take the inner ring fits. Tapered bore, installed directly on the tapered shaft or sleeve installed. Bearings with a cylindrical bore, press onto, or multiple-use and loading method
