Rolling bearing is an important mechanical component; whether the function of a mechanical device can be fully exerted depends on whether the bearing is smooth or not; it can be said that smoothness is a necessary condition for ensuring the normal operation of the bearing; And the use of the number of life plays an important role. No matter which smooth method is chosen; smoothness can have the following effects in rolling bearings:
.1) Cut the conflict between metals; slow down their wear and tear.
.2) The composition of the oil film increases the touch area; reduces the touch stress.
.3) to ensure that the rolling bearing can be under high-frequency touch stress; normal operation for a long time; extended fatigue life;
.4) Eliminate conflict heat; reduce bearing surface temperature; avoid burns.
.5) It is dustproof, rustproof and anti-corrosive.
Therefore, correct smoothing is very important for the normal operation of the rolling bearing. The smooth depiction of the rolling bearing mainly includes: the determination of a reasonable smooth method; the correct selection of the smoothing agent; the quantitative calculation of the amount of the smoothing agent and the determination of the oil change period. Smoothness can usually be divided into three categories: oil smooth, smooth grease and solid smooth. The oil smoother has a wider temperature range than other smooth methods; it is more suitable for high speed and high load operation. Bearings, together; because the oil is smooth, it also has the convenience of equipment protection and smoothing agent replacement, and the conflicts such as gears in the system can be smooth together; so far, the bearing oil is most smooth. The grease is smooth and has simple sealing equipment and repair costs. Low and smooth fat cost lower level of strength; used in low-speed, medium-speed, medium-temperature bearings, especially the advent of anti-wear additives in these years; improved grease smooth function; smoother grease has been more widely Use. If the oil is smooth and the grease is smooth, it will not be smooth. Pieces; or unable to meet certain conditions of work; it is possible to use solid smooth agent; or try to smooth the progress of the bearing itself functions.
