The bearing friction mechanism and the other bearing significantly different friction factors vary depending on the radial load, the wobble frequency, the oscillating frequency and oscillating angle, the temperature of the contact surface and the surface roug hness. General deep groove ball bearing movement within the outer ring relative to sliding friction, a larger friction; while the other bearing is in motion relative sliding friction compared to the cushion layer and the inner or outer ring, the friction coefficient small. Research shows that a significant difference in the skf bearing friction coefficient of the different materials under the same conditions, in the gasket material.bearing suppliers
With the continuous development of the bearing, the wear mechanism and form changing. Ships lubricated bearings in the work process, due to the relative sliding of the inner and outer rings, causing the bearing surface layer material is continuously loss, resulting in the bearings is not working properly. The main wear adhesive wear, abrasive wear and corrosion and wear 3 types. Deep groove ball bearing wear work due to the liner and the relative sliding of th e inner and outer rings, which led to the shedding of the liner, tearing, extrusion and other failure modes, the bearing does not work.
Bearing lubrication can be briefly described as follows:
a. layer of film is formed between the two rolling surfaces or sliding surfaces in contact with each other and spaced from the second surface to reduce friction and wear of the contact surface.
using oil lubrication, especially circulating oil lubrication, oil mist lubrication and injection lubrication, lubricating oil can take away most of the internal friction heat of the deep groove ball bearings, play an effective role in heat dissipation.
lubricated with grease, you can prevent external dust and other foreign matter from entering the bearing and sealing effect.
d. lubricant has a role to prevent metal corrosion.
e extend the fatigue life of the bearing.
As we all know, the appearance of the work always kept the dial gauge against the end face of the deep groove ball bearings or shaft proper position, even with the contemporary the highest manufacturing technology and processing skf bearing parts. Observe the reading changes with the pretension load method. The preload method has its negative aspects, such as imported bearing friction torque increases, increased temperature rise, shortened life expectancy and so on, so take full account of different levels of tiny geometric error, roller bearings and measurement clearance, shaft or bearing housing need in different directions rotation for several weeks, the ball ends deep groove ball bearings with inner ring on the leading edge in order to ensure proper contact.thin section ball bearing
Self-lubricating layer thinning, leading to the SKF bearing wear depth increases. Thus, bearing failure due to its continuous PTFE is extruded during the swing, the lubrication function decline, eventually leadi ng to knit substrate material wear.
