How to install the rear thrust bearing test

Install thrust bearing manufacturers, shaft ring and shaft should examine the vertical centerline. Method is fixed to the tank shell dial gauge face, the head of the table to touch the top of the bearing shaft rotating bearing ring raceway, while observing dial gauge pointer, if the pointer deflection, indicating ring and shaft centerline axis is not perpendicular. Tank shell hole deeper, we can still use an extension of the dial gauge head test.
Thrust bearing is installed correctly, the seat can automatically adapt to the rolling elements rolling, make sure to scroll down raceway body is located. If installed backwards, not only Double roller bearing is not working properly, and each mating surface would be subjected to severe wear. As shaft ring and seat ring and the difference is not very obvious, the assembly should be careful not to mistake. In addition, the thrust bearing race with the bearing hole should be left between 0.2-0.5mm gap to compensate for parts processing, the error caused by mounting inaccuracy, when in operation bearing ring center offset, this gap would ensure its automatic adjustment, avoid touching the friction to operate normally. Otherwise, it will cause severe damage to the bearing.

In shutdown, how to check of rolling bearings

In shutdown, how to check of rolling bearings
Periodically check the roller bearing co seal is a very important step. Optimal inspection time is arranged in a regular stop check period.
First, the importance of a clean bearings:A check is required prior to clean the surface of the machine, and then remove the bearing surrounding parts.2, the seal is very fragile parts, so need to be careful disassembly, do not use excessive force.3, then carefully check the seal and the surrounding parts, if you have shown adverse symptoms, be sure to replace the lost, poor seal will lead to bearing damage and lead to equipment downtime.Second, check the lubricant
Stained point lubricant friction between two fingers, if contaminants can feel it, or coated with a thin layer on the back of the hand lubricant and seal-ray.
Describes the importance of imports bearing lubrication and effect
Lubrication of the thin bearings, in particular, the fatigue life of the rolling bearing and friction, wear, temperature, vibration, etc. have a major impact. Without proper lubrication, the bearings will not work. Analysis to understand: Bearing causes of damage showed that about 40% of the bearing damage are related with poor lubrication. Therefore, well lubricated bearings is to reduce bearing friction and wear of effective measures.

Install needle bearing notes

 roll bearings clearance is defined as a case of a fixed ring, another ring in the radial or axial flow by the maximum amount, the clearance is divided into radial clearance and axial clearance two kinds . Move needle bearing assembly, the clearance is not too big, not too small. Clearance is too large, it will cause the load to move the body to withstand the reduced number of individual load increases to move the body, thereby reducing the accuracy of rotation of the bearing, reducing the service life; clearance is too small, the friction will increase, the heat generated increases, increased wear, also can reduce bearing life. Therefore, the bearing assembly must strictly control and adjust the clearance.

china bearing supplier temperature causes are: oil quality does not meet the requirements or deterioration, lubricant viscosity is too high; institutions assembly too tight (lack of space); bearing assembly tight; bearing ring on the shaft or housing rotation; overload large; bearing cage or rolling fragmentation.

1), the shaft and housing bore roundness and the vertical shoulder block bearing according to the appropriate precision requirements.

2), it is necessary to accurately calculate the rotating rings fit the amount of interference, but also suitable for accurate calculation of the amount of the fixed ring. Rotating rings blanch the amount of interference to the extent possible should also get smaller. As long as the operating temperature and ensure the effect of thermal expansion, and the maximum speed of the centrifugal force, resulting in a tight fit so as not to creep or sliding surfaces. Fixed ring size according to the work load and bearing size, select small clearance fit or interference fit, too loose or too tight is not conducive to maintaining the original shape exactly.
