Failure analysis of bolted roller bearings In recent years, our economic development has become better and better, as our industrial production demand has increased, so more machine products have been used by our industrial platform. We have seen bearings on many machines, and we all know that there are many varieties of bearings, so let's briefly inquire about the failure analysis of bolted roller bearings, I hope you can have more decomposition, So, let's follow the bolt roller bearing manufacturer to do a decomposition together with everyone. I hope you can have a new decomposition and inquire. 1. The bolt roller bearing is burnt. Burned bearings have signs of tempering on their raceways and rotating bodies. One of the reasons for the burn: the bearing is installed incorrectly and the position is in the wrong position. If the deflection is large, it is easy to cause the bearing temperature to rise and cause the bearing to burn; the second reason: the bearing is not lubricated enough, and the quality of the lubricating oil is not suitable Requirements or deterioration; Reason three: The bearing device is too tight, and the influence of thermal expansion is not considered during planning, resulting in smaller and smaller bearing clearances during operation. 2. The metal of the connecting frame is adhered to the rotating body. One of the reasons: the rotating body of the thin-walled bolt roller bearing is too tight with the connecting frame during the installation process. When the bearing is twisted at high speed, the rotating body is stuck in the connecting frame; the second reason: the quality of the lubricating oil does not meet the requirements or deteriorates , The lubricating oil pipeline is blocked, resulting in insufficient lubrication. 3. Cracks in the bolt roller bearing race. The reason for the cracks in the thin-walled bolted roller bearing race may be that the bearing is too tight, the outer or inner ring of the bearing is loose, the bearing part is deformed, and the surface of the installed bearing is poorly processed, etc. After reading the above analysis of the failure of the bolt roller bearing, you should have a little breakdown. I hope you can have some inquiries. Regarding bearing products, in fact, they all have high requirements for their quality, so as to ensure the safety of our machine applications. Our company's needle roller bearings are also one of our company's products. You can come and ask. of.
