In order to maintain the original performance of SKF bearings in good condition as long as possible, the need for industrial SKF bearing maintenance, repair, lubrication, in order to accident prevention in the first place, to ensure reliability of operation, improve productivity, economy. Maintenance best corresponding mechanical operating conditions, operating standards, on a regular basis. The surveillance operation, to supplement or replace the lubricant, the inspection of the regular demolition. Matters as the operation, maintenance, SKF bearing rotary sound, vibration, temperature, lubricant status and so on.
SKF bearing cleaning: remove bearing overhaul, first recorded the appearance of SKF bearings, confirm the amount of lubricant remaining sample to check with the lubricant, wash bearings. As a cleaning agent, ordinary gasoline, kerosene.
Removed to the cleaning of SKF bearings, points of rough cleaning and fine cleaning, were placed in the container, first put the bottom of the metal net, bearing no direct contact with the dirt of the container. Coarse cleaning, SKF bearings rotate with dirt, damage SKF bearing rolling surface, it should be noted. Coarse cleaning oil, use a brush to remove to grease, adhesive material, and generally clean, and transferred to the sperm washing.
Sperm washing, SKF bearings in cleaning the oil side of the rotation, while the careful cleaning. In addition, cleaning the oil should be kept clean.
SKF bearing, SKF bearing maintenance and judgment: and removed in order to determine whether you can use to check in the bearing clean. Check the raceway, the raceway, with state of the surface, the wear of the cage, the SKF bearing clearance increases and nothing to do with dimensional accuracy to drop damage, abnormal. Non-separation of small ball bearings, with one hand to the inner level of support, rotating outer ring to confirm smooth.
Tapered roller bearings and other separation shaped bearings, rolling element, the outer ring raceway surface were examined.
Large SKF bearings because they can not hand rotation, pay attention to check the rolling element and raceway, cage, rib surface appearance, the importance of the SKF bearing the higher the greater the need for careful check.
SKF bearing lubrication purposes:
Rolling bearings SKF's lubrication aim is to reduce the bearing internal friction and wear, to prevent burning stick, its lubrication utility as follows.
(1) to reduce friction and wear.
Constitute the SKF bearing rings, rolling element and cage contact with each other part, to prevent the metal contact to reduce friction, wear and tear.
(2) to extend the fatigue life.
SKF rolling bearing fatigue life in the rotation, the rolling contact surface oiled, will be extended. On the contrary, the low oil viscosity, the thickness of the lubricant film is not good, is shortened.
(3) discharge of frictional heat and cooling.
Cycle oil law and other oil discharge occurred by friction heat, the heat coming from the external cooling. Prevent SKF bearings from overheating, to prevent the lubricant itself aging.
(4) Other
Prevent the intrusion of foreign bodies within the SKF bearings, or to prevent rust and corrosion. Lubrication methods:
SKF bearing lubrication method is divided into the grease and oil lubrication. SKF bearing play function, first select the appropriate conditions of use, the purpose of lubrication method. If there is only a lubrication, oil lubrication lubrication dominant. However, the grease can simplify the expertise of SKF bearings surrounding structures, the pros and cons of grease and oil lubrication.
SKF Bearing Installation:
SKF Bearing installation is correct, and affect the accuracy, longevity, and performance. Therefore, the design and assembly department for bearing installation. I hope to be installed in accordance with the operating standards. Operating standards of the project is usually as follows:
(1) cleaning SKF bearings and related parts;
(2) check the connected components of size and finishing;
(3) installation;
(4) check the installed SKF bearings;
(5) the supply of lubricant.
To be installed, just open the SKF Bearing Package. General grease lubrication, cleaning, directly populate grease. Lubricating oil, general do not have to clean, instruments or high-speed SKF bearings and other use of clean oil wash, remove the coating on the SKF Bearing rust inhibitor. Remove the bearing of a rust inhibitor, rust, and so can not be placed regardless. Furthermore, the enclosed grease, SKF bearings, cleaning directly.
SKF bearings is due to the bearing structure, with different conditions general, due to multi-axis rotation, the inner ring needs interference fit. Cylindrical bore bearings, multi-press pressure in, or more hot charging method. The occasion of the tapered bore mounted directly on the taper of the shaft, or sleeve installation.
Installed on the shell, the general clearance with more than outer ring of the amount of interference, usually pressed into the press, or installed after cooling the shrink fit. Coolant with dry ice to expand and contract with the installation of the occasion, the moisture in the air will condense on the surface of the SKF bearing. Therefore, the appropriate anti-rust measures.
