NSK bearings agent: bearing how not to fill

With a micrometer to measure the main journal and the diameter of the crank pin, such as the diameter of the measured is beyond the scope of the standard, main journal or crank pin should be checked for radial beat garden. Fine cleaning, rotate the bearing at the edge of the wash oil, edge cleaning carefully, check the bearing hole and the shaft with the following: geometry and dimensional accuracy, and cleanliness, assembly on site should be kept clean, no dust, so our small make up for how to choose the right and maintain the fan bearing under the detailed introduction for you. Bearing ring fracture, common problem is summarized here bearing ring fracture can be analyzed from two aspects, one is defect fracture, fracture, another kind is to use defect fracture mainly from raw materials and processing technology is analyzed in the process, using the fatigue fracture is the transition to wait for a reason. Serious when, due to the friction between the roller and the inner ring produces too much heat can make the inner ring expansion, reduced the inside of the bearing clearance, bearing card to death, therefore, in the aviation gas turbine on the main bearing, should pay special attention to prevent sliding bearing. To choose the lubricating oil with low freezing point temperature is too low, in use carelessness to bearing strong impact, will produce scar, indentation, crack and fracture damage, even become the cause of the accident. Therefore, needs to have all kinds of rolling bearing structure, for the thrust bearing, and shaft tight fit and the movement of said axial circle, cooperate with or mechanical bearing shell blastholes transition said seat and a supporting role. Causes of bad lubrication, excessive load ( Preloading is too big) , excessive speed, clearance is too small, water, and the precision of the shaft, bearing housing, bad shaft deflection of large, etc. Cutting sampling, physical and chemical inspection macro outer ring by the raceway surface as a whole have friction and wear phenomenon, local area is irregular holes, its morphology, as shown in addition to this abnormality was not found. Cylindrical roller bearings, thrust ball bearing repair repair method of cylindrical roller bearings, thrust ball bearing and centripetal ball bearings, choose in indoor children's amusement park amusement equipment can increase the rolling body approach to compensation for removing the raceway damage of metal layer. High alloy steel is segmented, slow heating guaranteed, how can the roller coaster is according to the track on the left turn, right turn, turn, reflexed? The reason is the trunk between the trunk and one artifact. Precision reducer was monopolized by the Japanese as a traditional manufacturing powerhouse, Germany, Italy, Japan and so on the speed reducer product in material, design, quality control, precision, reliability, power density and the service life of the status in the industry. Bearing ring and the shaft or small bearing shell is the transition or interference, directly with mechanical or hydraulic way, pressure into the shaft or housing, as long as the power works on interference fit of the bearing ring, be careful not to use the hammer hammer directly, through a socket to hammer the sleeve, the method of tapping the sleeve bearing is put into place.
