Delete the SKF bearing repair, the first record of SKF bearing, confirmed that the remaining lubricant, lubricant sampling inspection, bearing. Common use gasoline, kerosene as a cleaner.
Open the code to import bearings cleaning, coarse and fine finishing clean points, respectively, in the container, put a metal mesh at the bottom of the first, SKF bearing no direct contact with the dust from the container. When cleaning, if rotating dirt SKF bearing, can damage the bearing rolling surface, should be paid attention to. In the rough, clean oil, use the brush to remove grease, adhesives, after cleaning, about into fine cleaning).
Good cleaning, SKF bearing rotating cleaning oil, carefully cleaning at the same time. In addition, oil always keep clean SKF Bearings Construction http://www.skf-ball-bearings.com/derby-bearings-uk.php.htm .
In order to determine whether to delete the SKF bearing can be used again, check the bearing after cleaning, check rolling, rolling surface, cooperate with the state, the wear of the cage, the increase of SKF bearing clearance, and dimensional accuracy, abnormal drop loss. Don't separate the types of ball bearing inner ring with one hand support levels, rotate the outer ring confirm whether smooth.
Tapered roller bearing separation SKF bearing, rolling body, surface of outer ring raceway can respectively. Large imported bearing can't rotate with the hand, pay attention to check the rolling element and raceway and the appearance, such as cage, defender SKF bearing high importance must be carefully checked.
Demand once confirmed the final value of the rated load, you must consider SKF bearing, install the required dimensions including here consider SKF bearing and fixed installation. With rated load bearing and matching requirements, the size of the shaft. These factors help to determine the structure and size of bearing, can also exclude some imported bearing type. Even in some cases, due to space limitations in the rated load to determine the rule out options.
Look very narrow if, for example, SKF bearing, ball bearing is the only type available in this work. Or, if you must use a very small diameter of bearing box, you need to be installed in the same two or more than two shaft roller bearing enough rated load.
When the size of the shaft and the request of SKF bearing rated load measurement phase, when there is a big difference, there is another common contradiction. If shaft is big but the load is light, even rated load is small, but it also puts forward an expensive, high rated load large SKF bearing, in this case, the best contact bearings manufacturers, in order to put forward the most economic and effective solution.
The instance
The basic working conditions. Assuming that SKF bearing used in reducer, imported bearings must support of about 25 mm diameter at one end of the shaft, shaft is installed on a gear.
The work cycle and imported SKF bearing load. Analysis and drive forces work cycle show that the radial load bearing had about three quarters of 1780 n, the speed of 11000 r/min, the running time of a quarter, SKF bearing radial load of 890 n, the speed of 3500 r/min. A good grid is almost do not produce axial force, not inclined wire or other effective axial force components. Expect the two direction maximum axial force is 89 n, 89 n power.
Size limit. Because of the limitation of internal gear reducer design allows the SKF bearing diameter is 70 mm, maximum interference degree is calculated by 6, the location of the maximum at 0001. Don't need a self-aligning bearing.
The environment. SKF bearing lubrication gear lubrication: from a large jar of injection, the highest temperature is expected to 140 degrees.
Reliability. SKF bearing continuous work must have a good reliability, reliable failure rate of 8%.
