The damage reason of tapered roller bearings during normal operation
 

Cone roller bearings use factors mainly refer to installation and adjustment, maintenance, maintenance repair and other compliance with technical requirements. According to the requirements of the bearing installation, use, maintenance, maintenance technology, IKO bearings in the running to take the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found abnormal immediately find reasons to adjust, restore normal. Installation conditions is one of the leading factors in the use factor, the bearing is often caused by the installation of inappropriate stress state between the various parts of the complete bearing change, bearing an abnormal state operation and early ending life of internal factors mainly refers to the three major factors of structural design, manufacturing process and material quality determine the bearing the quality of the.
The metallurgical quality of bearing material tapered roller is the main factor affecting the early failure of rolling bearings once. With the metallurgical technology (such as vacuum degassing of steel bearing) progress, improved quality of raw materials. Raw materials quality factors of failure analysis of the proportion has decreased significantly in the IKO bearing, but it is still one of the main factors of bearing failure. Proper selection is still bearing failure analysis must be considered.
Manufacturing of tapered roller bearings are generally after forging, heat treatment, machining, grinding and assembling multi-channel processes. Rationality, advanced, stability of the machining process can also affect the service life of bearing. The effect of heat treatment and grinding process quality of IKO bearings, and bearing failure is often
Rolling bearings make precision parts, and therefore requested the use of the corresponding support cautious attitude, both variable using tapered roller bearings with high performance, if used improperly, can not achieve the expected performance, so the use of tapered roller bearings that should pay attention to the following items:
Keep the tapered roller bearing and its surrounding environment clean. Even the eyes can not see the smile dust entering the IKO bearings, also will increase the wear of the tapered roller bearings, vibration and noise.
Use the installation carefully, do not allow powerful punch, not allowed to directly strike the tapered roller bearing with a hammer, not allowed to pass through the rolling pressure.
Use tools appropriate, accurate, as far as possible the use of special tools, the use of fabric and fiber or something to avoid.
To prevent the tapered roller bearing corrosion, direct hand take tapered roller bearings, should wash hands sweat, and coated with high quality mineral oil before operation, during the rainy season and summer with particular attention to anti rust.
With the tapered roller bearing
Inner diameter and outer diameter of IKO bearings are manufactured according to standard tolerance, bearing inner ring and shaft tolerance outer ring and the seat hole degree can only through tolerance and seat hole control shaft neck to achieve. With the bearing inner ring and shaft using the basic hole system, with the tapered roller bearing outer ring and the seat hole of the shaft.
The correct choice of cooperation, must know the actual load condition of the tapered roller bearings, working temperature and other requirements, but in fact it is very difficult. Therefore, in most cases it is used according to the selection of fine grinding.
Need to pay attention to selecting test point position and acquisition method in practice. To accurately reflect the state of rolling bearing vibration signal acquisition, must pay attention to the true and accurate, so from the IKO bearing the nearest place arrangement of measuring points in the motor free end generally have a rear fan cover, the selection of measuring point in the fan cover fixing screw has better monitoring effect. It should also be noted on the vibration signal acquisition and analysis of tapered roller bearings for many times, the comprehensive comparison. In order to get the accurate conclusion.
