The general use of the bearing, due to friction is small, less damage, so the service life of the rolling bearing can be achieved fatigue life. If in the course of the accident, may also cause early damage , which can not be used. General not because of the fatigue life reaches unavailable, we become the early damage, or directly call for the use of the breakdown or accident. And more generally on the installation, use, lubrication occur in Rolling.slewing bearing manufacturers
Rolling bearing structure; generally different mechanical structure, the process is not the same in different parts Rolling does not match, then certainly it is easy to make the rolling bearing damage.
To improve the machining process; Rolling is preferably used in the heat treatment processing aspects lower limit quenching temperature the appropriate extended holding time, and doing so can increase the concentration of the bearing alloy, can enhance the impact toughness of the bearing. Improved process monitoring tools; promote the improvement of process quality. Such as improved flow channel curvature position to monitor and improve the overall performance of the car bearing assembly, improving Rolling work.
Precaution
1, measuring body main bearing bore coaxially and roundness while measuring runout of the crankshaft, the thickness of the pad in this optional, so that the lubricating gap uniform. Scraping method can be applied to the preparation of the bush.
2, bearing repair and assembly quality, strictly control the quality of the connecting rod. New the old the rod uniformly requirements measurement parallelism and distorted, unqualified rod prohibited assembly; chock up and down two bearing watt mouth should be above the bearing seat plane 30-50mm, in order to ensure that the bearings will not loose ; assembly crankshaft prevent skew and bearing bolt torque so as to avoid the crankshaft bending deformation. Purification assembly site environment, produce cylinder liner dust cover, and to ensure the cleanliness of the diesel engine assembly.ball bearing suppliers
3, reasonable choice of filling oil, and to ensure that clean.

    The skf bearing friction mechanism was significantly different with the other bearing, the frictional force is mainly depending on the radial load, the wobble frequency, oscillating number, the swing angle, the temperat ure of the contact surface, and the surface roughness, and other factors. General deep groove ball bearing in the movement of the inner and outer rings relative to sliding friction, and its larger friction; liner layer and the inner or the outer ring while the other bearing in the movement, compared with the relative sliding under friction, the friction coefficient small. The study shows that, under the same conditions as the coefficient of friction of different materials SKF Bearing have significant differences, in the gasket material.
With the continuous development of the bearings, the wear mechanisms and forms of change. Usually lubricated bearings in the work process, due to the relative sliding of the inner and outer rings, thereby causing the bearing surface layer material continuous loss result in the bearing can not work properly. The main wear adhesive wear, abrasive wear and corrosion wear of three types. Deep groove ball bearing wear to work due to the relat ive sliding of the liner and the inner and outer rings, which caused the shedding of the liner, tearing, extrusion and other failure modes, causing the bearing is not working properly.bearing manufacturer
The role of the bearing lubrication can be briefly described as follows:
a. an oil layer is formed in the two rolling surfaces or sliding surfaces of mutual contact between the second surface spaced apart, reducing the friction and wear of the contact surface.
using oil lubrication, especially circulating oil lubrication, oil mist lubrication and injection lubrication, lubricants can take away most of the internal friction heat of the deep groove ball bearings, to play an effective role in heat dissipation.
greased, can prevent external dust and other foreign matter from entering the bearing and sealing effect.
d lubricant has to prevent metal corrosion.
e. extend the fatigu e life of the bearing.
As we all know, their work appearance always kept the dial gauge head against the end face of the deep groove ball bearings or shafts appropriate parts, even if it is with a contemporary superlative skf bearing parts of manufacturing technology and processing. Observe the changes in the method of its readings with the pretension load. Pretension method has its negative aspects, such as the imported bearing friction torque increases, the temperature increase, and shortened life expectancy, so to take full account the different levels of tiny geometric error, roller bearings and DD clearance, shaft or bearing boxes need be rotated toward different directions several weeks, to ensure that the ball end portion of the deep groove ball bearing with the proper contact on the leading edge of the inner ring.ball bearing manufacturer
Self-lubricating layer thinning, lead to the skf bearing wear dep th increases. Thus, the reason of the bearing failure in its swing process PTFE constantly being extruded, the lubricating function decline, eventually leading to the woven base material wear occurs.
