1. Influence on bearing life The SKF bearing sanitary degree has a considerable influence on the life of the needle roller bearing; the bearing has carried out special experiments for this purpose; the result is that it is not several times or even dozens of times more. Bearing The higher the degree of hygiene; the longer the lifespan, the other people's experiments indicate that smooth oil with different sanitation has a great influence on the life of the ball bearing. Therefore, improving the hygienic degree of the smooth oil can extend the life of the bearing; The oil-containing dirt particles are controlled below 10um; the bearing life is also increased several times. 2. Influence on the oscillation noise The experimental results in the middle of the bearing experiment indicate that the hygienic degree seriously affects the oscillation level of the SKF bearing; especially in the high frequency band. The oscillation is more obvious. The high hygienic bearing oscillation speed value is low; especially in the high frequency band; the effect of dust on the noise of the needle roller smooth grease has been tested; the more the dust is, the more noise is. The smooth function affects the hygienic degree of SKF bearing; it not only affects the composition of smooth oil film; it also causes the smoothing of smooth grease and accelerates its aging; then it affects the smooth function of smooth grease. Anti-rust treatment; we can think that the entire roller is coated with a layer of anti-rust paint; this will be a good way to deal with the anti-rust problem; the selection of anti-rust paint needs to be selected; can not use the residual products; otherwise it is difficult to play Anti-rust treatment, when the whole needle roller bearing is installed, we need to do a preventive method; the simple problem of neglecting in the meantime is that the time of the device is the best with gloves. The time for the bearing of the device must prevent the bearing from entering. Foreign matter. Due to the fine layout inside the needle bearing; any foreign matter entry will bring fatal flaws to the layout of the SKF bearing; the necessary smoothness should be adhered to during the installation; and it must be sealed well. Compared with the usual mechanical parts; the precision of the imported bearings is high; therefore, it should be carefully handled when using it. 1) Adhere to the hygiene of the bearing and its surroundings. 2) Carefully use the thick and large leaves to give the bearing a severe impact when used. The bearing is scratched, indented, cracked, etc. 3) Apply suitable things 4) Pay attention to the rust prevention of the bearing to prevent it from being used in wet places; Do not wear sweat; should wear gloves. 5) The user should understand the bearing 6) The operating standard for the preparation of the imported bearing a, the storage b of the bearing, the clearance of the bearing and its surroundings c, the scale of the device and the inspection of the processing quality d, device operation e, view f after device, open work g, protection protection (timed view) h, smoothing agent make up
