26 non-standard bearing maintenance for non-standard bearings use and always maintain its some characteristics, it is important to further strengthen maintenance in time,
Regular maintenance)
。
According to the regular maintenance of appropriate, to ensure early find common failures, to avoid safety accident development is critical to improve the production efficiency and rationality.
Non-standard bearing cleaning the non-standard bearing down to examine, with shooting methods such as well first appearance record.
In addition, to determine the amount of the remaining lubricant and lubricant sampling, then clean the bearing.
A, non-standard bearings cleaning rough washing and fine washing, can be put in the application of the vessel bottom and spherical metal material on the rack.
B, rough washing, in the selection of oil soft brush, remove grease or gelling.
At this time if in oil bearing rotating, note will turn because dirt such as damage to surface.
C, fine cleaning, slowly rotating bearings in the oil, must be carried out carefully.
General application of cleaner diesel or gasoline for neutralization water content, on the basis of temperature must sometimes applied caustic soda solution, etc.
No matter use which cleaner, must often blocking clean.
After cleaning, immediately on the bearing sizing rust inhibitor or antirust processing fat.
5% of chromium and hypereutectoid steel with a small amount of manganese and silicon.
Chromium can improve heat treatment process characteristics, improve cutting performance and body proportions, quenching reliability, and can promote antirust processing properties of steel and cutting properties.
When the chromium content is more than 1.
65%, the content of residual martensite after heat treatment in steel increases, the strength and reliability is reduced, the nonuniformity of cementite, fracture toughness and fatigue limit of steel is reduced.
As a result, the magnesium content of high carbon chromium non-standard bearing steel general control in 1,65 % the following.
Only to rein in the non-standard bearing steel composition, can according to the heat treatment process are the property of non-standard bearing institutions and intensity.
