What bearing bearing type size query: 8000 turn use

First of all, the operating temperature of the fan shaft size, speed, wear, such as data; Within the bearing into the oil, will wash, heating some minutes, take out after heat on the journal. Will let bearing box end cover to offshoring, use TAB to get between bearing housing and the space between the outer ring, possible axial spring force on the outer ring, in order to reduce the axial shaft floating. High welding strength, however, PeVue used high-speed sampling technology, the signal after a high-pass filter to the number of sampling points per second fixed for all, to the complex frequency domain signal transformation to the time domain, you can repair the rotating equipment in several ways, at the same time understand the cause of the problem and how to avoid these problems. Small failure rate in the running, it can reduce the maintenance work of manpower and material consumption, thus while rolling bearing axle box device manufacturing cost is far higher than that of sliding bearing axle box device, but still get more and more widely adopted. There is a common small bearing, replace this widget can only when replacement, price is very cheap, but more troublesome, to change partners than in integral. Under high stress, or in the condition of lack of oil, the friction between objects will have a lot of friction heat, sometimes, the heat is to contact the local melting state, thus appear instantaneous welded, and then will be torn apart, the consequences are the cause of contact area between metal migration, the wear is called adhesion wear, as shown in figure - Shown below. Bearing heating method: electric heating plate bearing heating method be placed on the electric hot plate temperature ℃ for a few minutes, this method is simple, such as reverse it a few times can make the bearing heated evenly, and the efficiency is high, the size of the bearing can use this method. This structure makes it in the car factory assembly difficulty, high cost and poor reliability, and when the car in pits maintenance, also need to clean, oil bearing and adjustment. Deep groove ball bearings to install use, because as much as the axis of rotation, so the inner ring and outer ring can respectively USES the interference fit and clearance fit, the outer ring rotates, the outer ring USES the interference fit. From the function and structure, main shaft bearing can be divided into two categories, the rolling bearing and sliding bearing, sliding bearing based on its way to produce the oil film pressure difference, can be divided into fluid dynamic bearing and hydrostatic bearing. Composite lubrication bearings used in composite material is a new type of extreme pressure lubrication materials, solid by metal substrate and the solid lubricant embedded substrate holes or slots of paste. Rolling bearing clearance change failure at work, because of the influence of the external or internal factors, makes the original fit clearance change, precision is reduced, and even cause 'killed, known as the clearance change failure.
