There are many reasons for the failure of forklift bearings. All influencing factors in the design and manufacturing process will be related to the failure of IKO bearings, which is difficult to judge by analysis. In general, it can be considered and analyzed from two aspects: use factors and internal factors.Three factors affecting bearing failure of IKO forklift
Three factors affecting bearing failure of IKO forklift
Use factors mainly refer to whether the installation, adjustment, use and maintenance, maintenance and repair meet the technical requirements. The installation condition is one of the primary factors in the use factors.
The improper installation of IKO bearing often leads to the change of the stress state between the parts of the whole bearing, and the bearing operates in an abnormal state and fails early.
According to the technical requirements of bearing installation, use, maintenance and repair, monitor and inspect the load, speed, working temperature, vibration, noise and lubrication conditions borne by the running bearing, find out the cause immediately and adjust it to make it return to normal.
In addition, it is also important to analyze and test the quality of grease and the surrounding medium and atmosphere.Three factors affecting bearing failure of IKO forklift
Internal factors mainly refer to the three factors that determine the quality of IKO bearing, such as structural design, manufacturing process and material quality.
First of all, the reasonable design and advanced nature of the structure will lead to longer bearing life. The manufacturing of bearings generally goes through multiple processing processes such as forging, heat treatment, turning, grinding and assembly.
The rationality, advanced nature and stability of all the processing technologies will also affect the life of bearings. Among them, the heat treatment and grinding processes that affect the quality of finished IKO bearings are often more directly related to the failure of bearings.
In recent years, the research on the metamorphic layer on the working surface of bearing shows that the grinding process is closely related to the surface quality of bearing.
The metallurgical quality of forklift bearing materials was once the main factor affecting the early failure of rolling bearings. With the progress of Metallurgical Technology (such as vacuum degassing of bearing steel), the quality of raw materials has been improved.
The proportion of raw material quality factor in IKO bearing failure analysis has decreased significantly, but it is still one of the main influencing factors of bearing failure. The proper selection of bearing material must still be considered.Three factors affecting bearing failure of IKO forklift
The main task of forklift bearing failure analysis is to find out the main factors causing bearing failure according to a large number of background materials, analysis data and failure forms, so as to put forward targeted improvement measures, prolong the service life of IKO bearing and avoid sudden early failure of bearing.Three factors affecting bearing failure of IKO forklift
During the periodic maintenance and operation of IKO bearing equipment and the replacement of peripheral parts, when the search and inspection of the disassembled rolling mill bearing is suspended, it is necessary to judge whether the secondary bearing parts can be reused and record the good or bad application conditions.
Also make great efforts to inquire, visit and record the removed IKO bearings and appearance conditions. In order to find out and inquire about the remaining amount of lubricant, after sampling, clean the bearing well.
Secondly, check the raceway surface, rolling surface and joint surface of IKO bearing and the wear condition of confrontation frame for damage and abnormal conditions.
In particular, check the running track of raceway surface. To judge whether the rolling mill bearing can be used again, we should think about the level of bearing damage, mechanical function, priority, operation premise, search and inspection cycle, etc.Three factors affecting bearing failure of IKO forklift
Search and inspection results. If IKO bearing is found damaged and abnormal, please find out the notice and formulate countermeasures according to the phenomenon of bearing damage.
In addition, the inspection results show that if there are the following defects, the rolling mill bearing can no longer be used. It is necessary to replace the IKO bearing with a new one.Three factors affecting bearing failure of IKO forklift
Any one of the inner and outer rings, rolling elements and confrontation frame has cracks and fragments.
Any one of the inner and outer rings and rolling elements has peeling.
The raceway surface, retaining edge and rolling element are significantly jammed.
The standoff frame is severely worn or the rivets are loose and ferocious.
The raceway surface and rolling element are rusty and scarred.
The rolling surface and rolling body have significant indentation and indentation.
There is creep on the inner diameter surface of the inner ring or the outer diameter of the outer ring.
Overheating and discoloration are fierce.Three factors affecting bearing failure of IKO forklift
