Bearing clearance: how to replace the bearing three-phase asynchronous generator

Tank capacity should be and the size of the heated bearing and oil amount, if the container is too small, in continuous operation, into the bearing oil temperature will drop quickly, the effect is bad. Process: a back pack good half bearing sleeve, measure the clearance should be qualified, all lubrication part, lubrication points according to embellish the diagram 'five set' for refueling, lack of oil dry milling phenomenon; c。 According to statistics, in the use of roller bearing of rotating machinery, due to damage of rolling bearing fault accounting for %, as a result, the working condition monitoring and fault diagnosis of rolling bearings technology research more and more get people's attention. All of rolling bearings is cylindrical, cone and sphere, the spherical roller bearing under axial load is better, but it requires the size is bigger, does not favor the unsprung weight, and the manufacturing cost is higher, maintenance inconvenience, so adopt less in recent years. Oils have impurities; , N and NU type cylindrical roller bearings will datum in the direction of the spindle shaft shoulder installation, shall ensure that in the process of testing ring does not produce axial displacement. Axial parts of technical requirements, material and technical requirements: the blank with the bearing axis neck, transmission parts installed shaft head surface is one of the important surface of shaft, to put forward the important technical requirements, such as: dimensional accuracy: Ф h Ф f. ; Rolling bearing is standardization, seriation, generalization, suitable for mass production and supply, use and maintenance is very convenient. Rolling bearing made of bearing steel, and after heat treatment, therefore, the rolling bearing not only has high mechanical performance and longer service life, and can save the manufacture sliding bearing used in price is more expensive metal; Rolling bearing internal clearance is small, the processing precision of parts is higher, therefore, high precision. On many back to the rotation sealing device, magnetic liquid seal has been widely used, such as monocrystalline silicon furnace, vacuum brazing furnace, vacuum melting furnace, chemical vapor deposition, ion plating, vacuum equipment, such as liquid crystal regeneration sealed, as well as high temperature and high pressure equipment and to [ wiki] Environment [ / wiki] To demand higher sealing equipment. NC system control way of the spindle, the light bulb heating method is suitable for small and often do not need; To the bearing heating, light bulbs still can make lighting at ordinary times, moreover does not need any other equipment. As this symbol will appear on the angular contact ball bearing; The Swedish SKF bearing U ( DU) - - Contour grinding of angular contact ball bearing NSK NSK bearings D or DU expressed deep groove ball bearings, angular contact ball bearing surface non-contact rubber dust cover. To open washing, cleaning to be carried out in accordance with the bearing installation drawing and dismantling, cleaning after recovery also should according to the installation of the installation drawing right, up and down two sets of assembly shall be in accordance with the original drilling position, so as not to affect the normal use of the wheel bearing. Atmospheric pressure, completely meet the needs of the vacuum seal, in sliding bearing, the hydrostatic bearing, the fluid dynamic bearing, gas static bearing, gas dynamic bearing is fit for high speed rotation.
