There may be many factors that can affect the service life of the bearing, use factors and internal factors, could further instructions.
Use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements.
According to the bearing installation, use, maintenance, maintenance of technical requirements, the operation of the tapered roller bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal.
Installation conditions is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing at the end of the abnormal state of operation and early life.
To make the bearings and keep its long-term performance into full play, must earnestly to do regular maintenance (
Regular inspection)
。
Through proper periodic inspection, do early detection of fault, prevent accident arrangement is very important to increase productivity and efficiency.
1, clean the bearing will be removed, with photography method such as first and then record the appearance.
In addition, to confirm the amount of residual lubricant and lubricant sampling, and then wash the circular cone roller bearings.
A, bearing cleaning divided into rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame.
B, rough washing, oil using a brush to remove grease or adhesive.
If at this time in oil bearing, pay attention to the rolling surface due to foreign bodies such as damage.
C, fine cleaning, slowly rotating bearings in the oil, must be carefully.
Commonly used cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc.
No matter use which kinds of detergent, often should filter clean.
After cleaning, immediately on the tapered roller bearing coating anticorrosive oil or antirust grease.
2, examination and judgment to judge remove the bearing can be reused, to inspect the dimension precision, rotating accuracy, internal clearance and mating surface, raceway surface, cage and seal rings etc.
About the test results that can be used by bearing the judgement or master of tapered roller bearing.
Judgment standard according to the mechanical properties and important degree and inspection cycle.
If you have the following injury, bearing shall not be used again, must be replaced.
A, fracture and defect of bearing parts.
B, raceway surface rolling strip below.
Bearing manufacturing generally go through forging, heat treatment, cutting, grinding and assembly, and multi-channel processing operations.
The rationality of the processing technology, advanced, stability will also affect the service life of bearing.
Which affects the quality of finished product tapered roller bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure.
In recent years the study of metamorphic layer of bearings working surface show that the grinding process and is close to the surface quality of the bearing.
The previous: bearing materials should have under the performance of an article: bearing radial clearance -
