370000 type double row circular cone roller bearings installed

Type double row circular cone roller bearings to install 2021-370000 03 - 08 Dong Weiliang one, this type of bearings can withstand radial and axial load at the same time, there are two outer ring, a baffle, a set of components. Bearing manufacturing clearance when the products leave the factory, according to user's working conditions and with reference to the national standard with baffle adjustment well, users only can be installed in the correct procedures. Second, the bearings to install the scene, opened the package, check if there is a knock against rust, transportation of be affected with damp be affected with damp bearing. Three, bearing rust using water soluble agent, no chemical change, contact with different grease metamorphic reactions will not occur. Four, bearing installation steps: clean with clean kerosene, roll neck, bearing box seat hole gland, check whether there is contact with the bearing part burr, bumps, if yes, can use sand cloth or polishing machine polishing smooth. Check the bearing box seat hole, in addition to check whether the form, size out-of-tolerance, also check the load area installed two outer ring of the corresponding position, to see if there is an obvious between two outer convex sets, if size out-of-tolerance and there are obvious convex sets, recommend replacing new bearing box. Measuring the actual height of the bearing, gland out height of seam allowance, combined with the bearing box clear height of calculate the maximum of gasket. ( H1 + H2 + B - L) / 2 = X shim thickness & lt; X。 First installed on only one side of bearing housing gland, the flip horizontal platform, in turn into the first outer ring, ring, inner sleeve insulation components, the second outer ring, in the process to turn the inner ring, to ensure that the first outer end face and gland paste, the raceway and roller fit well, the first column packed this side of the gland. Turn the bearing inner ring by hand, check whether there is a delay velocity, jam phenomenon, if in good condition, after sealed bearing box seat holes can be placed on the spare area. Five, will have been installed and active maze roll loaded on the bearing box, combining with the axial clearance of the bearing, the bearing inner sleeve between capillary and pressing sleeve ends set aside a certain numerical aperture e, this is very important, it can ensure the bearing work, load can maximize the average allocation to the two columns of the scroll body. 6, add the work of the grease according to the needs of the production line, in the above link or on-line injectors. Seven, special considerations: on the roll system and the part of the seal lip contact roughness is in line with the requirements. And roll end joint moving maze is there enough interference on the roll, otherwise, will produce displacement in the bearing use, cause bearing inner ring end face wear and tear, serious when bearing radial radial crack face appear. Eight, suggestion: bearing online use after a period of time, according to the working condition, will be 90 bearing two outer load area & deg; ~120° Adjustments, such doing can effectively prolong the service life of bearing. （ Source: WeChat ID DMD_bearing)
