Way to solve the TIMKEN bearing heating failure

TIMKEN bearings lubrication method there are several kinds, and various types of bearings and all kinds of bearings used in lubrication also are not the same, which is more conducive to maximize service life of TIMKEN bearings, is the mechanical performance of the device is in the highest State of efficiency
1, oil lubrication:
Viscosity lubricating oil is an important characteristic, liquidity and size directly affect the viscosity of lubricating oil film thickness of the friction surface formed between, TIMKEN bearing operating temperature viscosity of lubricants in General is 12-15cst. Higher the speed should be selected lower viscosity, heavier the load should be selected high viscosity. High speed machinery commonly used lubricant oil, 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, for low, medium lubrication of bearings, bearing part submerged in a tank in the lubricants from bearings of rotating parts, and then flows back to the oil 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 drops every 3-8 seconds, too much oil will cause increased bearing temperature.
C. circulating oil lubrication
The filtered oil to the bearings with oil pump parts, by bearing lubricating oil filter again after cooling after use. Due to the circulating oil can take a certain amount of heat, cool the bearing, therefore law is applicable to high speed bearing parts.
D. spray lubricant
Drying of compressed air through the formation of aerosol is mixed with the lubricant oil mist, Jet bearing, air can effectively cool the bearing and prevent intrusion. This method suitable for high speed, high temperature lubrication of the bearing components.
E. spray lubrication
Oil pump high pressure oil nozzle into the bearing, oil the bearing into bearing the other end into the oil tank. In the bearings rotate at high speed, rolling elements and cage to very high rotation speed so that the surrounding air to form air general lubrication method is difficult to bring their oil to bearings, in which case you must use high pressure Jet method spray of lubricating oil to the bearing, position of the nozzle should be placed between the inner ring and the cage Center.
Bearings are fixed parts in the machine, is a mechanical body, its role is basically to keep the axis center position, and control the movement of mechanical parts. TIMKEN bearings have a decisive role in any machinery, without bearings, machinery cannot function.

Previous: Effects of attention using TIMKEN bearings temperature is too high
Next: Pillow block bearing lubrication maintenance of heating methods
