Influence of treatment technology of bearings of printing machines on quality of printed output

Gavrysh A. P., Royik T. A., Mel’nyk O. O., Vitsyuk Yu. Yu. Influence of treatment technology of bearings of printing machines on quality of printed output
In the article the method of magnetic-abrasive finishing of new materials sliding bearings for heavy exploitation conditions of polygraph machines have been shown. The influence for working surfaces properties of friction details and printing production’s quality have been presented.
It was determined the new developed conditions of finishing increase the quality parameters of surfaces in 1,5–2 times in comparison with traditional methods.
Researched results of optical density showed equal distribution of ink layer along a whole of surface print at functioning new sliding bearings in friction units.
Using of bearings on the basis of nickel alloy ЭИ 929 – CaF2 and on the basis of copper ДН5М3КФ9 which were finished at new fine abrasive grinding in the friction units of printing machines assists increase of quality the printed output and decrease of the rejects to 2,0–2,2 %.
