Lubrication of the bearings in several ways, and various types of TIMKEN bearings and bearing with lubrication also is not the same, so better to maximize the service life of the bearing, is the State machinery and equipment performance is at the highest efficiency
Are important characteristics of lubricating oil viscosity, viscosity size directly affect the fluidity of lubricating oil and oil film thickness in the formation of friction surface, bearing temperature viscosity of lubricants under General 12-15cst. Higher speeds should select low viscosity, heavier load should be selected high viscosity. Commonly used lubricant oil, high-speed machinery oils, turbine oil, compressor oil, transformer oil, cylinder oil.
Oil lubrication methods include:
A. oil bath lubrication
Oil bath lubrication is the most common method of lubrication, suitable for low and medium-speed bearings lubrication part bearings submerged in the slots, INA bearings from rotating parts with lubricating oil, and then flow back into the tank oil level should be slightly lower than the lowest rolling element Centre.
B. oil lubrication
Drops of lubricating oil suitable for the need to ration Lube bearing parts, oil drops General drops every 3-8 seconds, too much oil will cause increased bearing temperature.
C. circulating oil lubrication
Pump the filtered oil to the bearing parts through bearing lubricating oil filter after use after cooling. Due to the circulating oil can take a certain amount of heat, to cool off the bearing, therefore bearing part of the law applicable to the high speed.
D. spray lubrication
Use dry compressed air through sprayer mixed with oil to form oil mist, Jet bearing, air can be used effectively to cool off the bearing and prevent intrusion. This method for high-speed, high-temperature lubrication of the bearing parts.
E. spray lubrication
Oil pump high pressure oil nozzle Jet bearing, into the bearing oil the bearings into the tank at the other end. The bearing when spinning, rolling elements and cage to a high rotation speed of the surrounding air to form air general lubrication method is difficult to bring oil to the bearings, in which case you must use methods of high pressure jet oil spray to the bearing, position of the nozzle should be placed between the inner ring and the cage Center.
Bearings are fixed parts in machinery, mechanical body, its role is basically to keep the axis center position, and control the movement of parts. Bearings have a decisive role in any machinery, without bearings, machinery cannot function.
Many users are reflected in use when bearing, failure is the most common of the heating in the bearings, this failure will affect the life and performance of bearings. So, how does this failure? The following, is to conclude that several points of knowledge for everyone.
1, the oil level is too low, loss of lubricant from the oil seal;
2, grease in the bearing box completely filled or the oil level is too high. This can lead to excessive mixing lubrication, high temperature or oil spills;
3, contact-type (friction) oil seals are too dry or spring too tight;
Holes in the bearing box of 4, not circular; housing distortion; uneven supporting surface; box hole diameter is too small;
5, contact-type (friction) oil seals are too dry or spring too tight.
