SKF bearing structure on the effect of vibration and noise

When SKF bearing under radial load and the oil cases of poor performance, running initially heard "click, and click" noise, this is due to the bearing after leaving the loading area, issued suddenly accelerated and collided with the cage of the bearing noise, the impact sound inevitable as operation will disappear after some time.
Cage noise prevention measures are as follows:
A. in order for the cage of orbital motion stability should as far as possible using rings boot and boot attention given adequate lubrication, tapered roller bearings under high speed conditions improve, roller guide ring flanges instead of l-shaped cage boot Z-type cages.
B. SKF bearings rotate at high speed, Pocket Hole clearance of bearing cage vibration amplitudes greater than small pocket hole clearance of cage vibration amplitude, Pocket Hole gap value is particularly important.
C. should pay attention to minimizing the radial clearance.
D. preserve manufacturing precision as possible, improve the surface quality of cage, conducive to reduce bearing and cage of noise generated by collisions or friction.
E. actively adopts advanced cleaning technology, spare parts and products for effective after thorough cleaning, improving the cleanliness of SKF bearings.
5. bearing by vibration
While the SKF bearing under radial load is running, its internal only if several bearings are subjected to load, because the rings consisting of elastic contact "Spring" supporting role through the radial bearing load lines to generate periodic vibrations, and hinge Centre will move vertically or horizontally from top, while noise is thrown. This type of vibration known as the bearing by vibration, particularly in the more evident during low-speed operation.
While its amplitude and SKF type, radial load, the radial clearance of bearings and bearing the number. Usually the smaller amplitude, large amplitude only when hazards, often using radial clearance reduction or impose the appropriate preload to reduce.
