Fl bearing, bearing vibration velocity big what reason be

Boot wear appeared again two days later, the vibration value is more and more big, the enterprise again after removal of bearing pad of the copper foil way in times of emergency handling, equipment operation days later again vibration. The role of the diesel engine main bearing is bearing the crankshaft, protect the normal operation of the crankshaft and power output, first of all, the bearing load on the body, the crankshaft into again, after completed loading tiles. His process characteristics is: keep vehicles plastic injection forming, can obtain precise geometry and dimensional accuracy and low surface roughness value, without mechanical processing, high production efficiency. NSK bearings and changing the lubricant, bearing of the working environment is also very important, many mechanical work in import bearings because the environment is not enough, lead to an early end of imported bearing life. The first step, the vehicle with lifting machine up, dangling the wheel and loosen the hand brake; The first step, the driving wheel, can be manually by arrive slow fast rotating wheels, check whether there is bearing noise; The first step, when the test drive wheels, launch vehicle idler wheel, to check whether there is additional bearing noise. 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. Not scratch, scratch because the lubricating oil filter net, metal particles are worn down, or mixed with some impurities in installing a process, and the size of the metal particles, may be greater than the small oil film thickness, and due to the contact area between sliding phenomenon, the existed between two contact surfaces of hard small clever grain and will scratch the work surface. & emsp; & emsp; Motor in use should be washed after hours and refueling, short centripetal ball bearings and cylindrical roller bearings when cleaning ball, pearl, should be the inner ring and outer ring off to clean. Preloaded, bearing radial, axial and Angle stiffness increase with the increase of rotational speed, but the increase of the axial stiffness and Angle quite gentle, pre-tightening load with the increase of pre-tightening load, the influence of the radial, bearing. Grease is a thickening agent which is composed of dispersed in the liquid lubricant is kind of stable solid or semisolid product, which can add to improve some characteristics of grease additives and fillers. Try myself tools/raw material axial wrench, die casting aluminum alloy cage, need large tonnage equipment, mold design and manufacturing complex, easy to make a cage pocket hole strain when die casting. In addition to the cause and costly maintenance downtime, bearing assembly and improper installation may also have more effect, such as interfere with the operation of other parts, shorten its service life, etc.
