Engineering plastic bearing, self-aligning bearing main performance is what

Cylindrical roller and race as line contact bearings, table measurement method and the difference of two table measurement table method measurement table from two big difference between measurement more accurate. When bearing inside diameter tolerance zone with axle tolerance zone, as base hole system in the central plains of transition fit tolerance code will be a win to cooperate, such as KKMMN - Methyl amino acetonitrile, etc. , but a win is; When the bearing inside diameter tolerance generation with hh, etc, is not clearance and become a win. Maintains a broken solution: check the conditions of use; Check the lubrication conditions; To study the choice of the cage. Pay attention to the bearing use; The shaft and bearing box rigidity. The whole process is: the bar stock or tube ( Some bar need to the forging, annealing and normalizing) - - - - Car processing - - - - Heat treatment - - - - Grinding - - - - - lapping and polishing - - - Final inspection - parts - - - - - - - - Rust - - - - Warehousing - - - - - - - - - - - - - - ( Stay close set of assembly> steel ball processing procedure. If in some special occasions to use higher speed bearings, such as used in high-speed cutting machine tools and precision machining of high speed rotation axis ChengHai can use ceramic bearings, electrical, magnetic bearings and other special bearings, will contact the professional manufacturers. Avoid using hard tools or gravity batting cage, its typical form is on the ball appear occupies an area of many concentric circles ( 'The cat's eye') Scratch ( Figure. In the early days of aviation gas turbine engine, in order to solve the problem of the balance of the cage, how will be the main bearing cage in the outer ring, but this design is easy to cause the bearing slide injury. Carefully choose the single slope design now refer to ABS in American bureau of shipping part and mechanical part of steel ship specification ship system can find clear requirements, for the ship without front bearing device, in the stern tube of stern tube bearing must be double slope after ( doubleslope) As shown in figure design, unless proper technical documents submitted to the single slope (Ming sin- Methyl amino acetonitrile gleslope) Designed to provide an equivalent or better design, will give the single slope ( sin- Methyl amino acetonitrile gleslope) Design of special consideration. First put bearing in gasoline cleaning, wipe residues of sludge and dust on the bearing, bearing all rusty wipe gently with the metallographic sandpaper polished, until no fingered rough feel. Practice of bearing in the speed and frequency of different rotational speed, and whether there is a corrosion phenomenon, in what place, what type of corrosion, whether related to the failure directly. Can meet the requirements of use for a long time, after the deformation of connecting rod, can make the piston in the cylinder askew, cause the piston and cylinder, connecting rod bearing and connecting rod journal of partial grinding, cylinder, cylinder, etc. Can also be used for cutting the magnetic line of force principle to measure the rotational speed of the cage, according to the understanding of bearing knowledge for many years, tell everyone about these problems, we are a few tips below can be solved.
