The use factors of tapered roller bearings mainly refer to whether the installation adjustment, use and maintenance, maintenance and repair meet the technical requirements. According to the technical requirements of bearing installation, use, maintenance and maintenance, monitor and check the load, speed, working temperature, vibration, noise and lubrication conditions of the running tapered roller bearing, and find the cause immediately and make adjustments if any abnormality is found. , it returns to normal. The installation condition is one of the primary factors in the use factor. The bearing often changes the stress state between the parts of the whole set of bearings due to improper installation. The bearing runs in an abnormal state and ends its service life early. The internal factors are mainly Refers to the three major factors that determine the quality of bearings, such as structural design, manufacturing process and material quality.
1. Improper installation (about 16%)
1. Use brute force during installation, and directly hitting the tapered roller bearing with a hammer will cause great damage to the bearing; it is the main cause of deformation.
2. The installation is not in place, the installation is deviated or not installed in the bearing position, resulting in too small clearance of the tapered roller bearing. The inner and outer rings are not in the same center of rotation, resulting in different centers.
Suggestion: choose appropriate or professional bearing installation tools, and use special instruments to test after installation.
2. Poor lubrication (about 50%)
According to the survey, poor lubrication is one of the main reasons for premature bearing failure. The main reasons include: not adding lubricant or lubricating oil in time; not filling lubricant or lubricating oil in place; improper selection of lubricant or lubricating oil; incorrect lubrication method, etc.
Suggestion: choose the correct lubricant or lubricating oil, and use the correct lubrication and filling method.
3. Pollution (about 14%)
Contamination can also lead to premature failure of tapered roller bearings. Contamination means that dust, metal chips, etc. enter the inside of the bearing. The main reasons include: unpacking the tapered roller bearing prematurely before use, causing pollution; unclean working environment during installation, causing pollution; unclean working environment of the bearing, pollution of the working medium, etc.
Recommendation: Do not unpack the bearing before use; keep the installation environment clean during installation, and clean the bearing to be used; strengthen the sealing device of the bearing.
4. Fatigue (about 34%)
Fatigue failure is a common damage method for tapered roller bearings. Common causes of fatigue damage may be: long-term overload operation of bearings; failure to maintain in time; improper maintenance; equipment aging and so on.
Suggestion: choose the appropriate type of tapered roller bearing, and replace the fatigue bearing regularly and in time.
