Bearing (Bearing) It is a kind of important spare part in contemporary mechanical equipment. Its main function is to support the mechanical solid of revolution, reduces the coefficient of friction (friction coefficient) in its rate process ,And guarantee it turns precision (accuracy) round .
Rub the difference of properties according to the movement component, the bearing can be divided into an antifriction bearing and big class of the sliding bearing two. Among them antifriction bearings have been already canonicalization, seriation, but compare with sliding bearing its radial size, vibration and noise are relatively great, great too of the price.
The antifriction bearing is generally made up of outer lane, inner circle, rolling element and part of retainer four, it is made up of outer lane, inner circle, rolling element, retainer, sealing, major possession of lubricating oil six that it is said that rigorous. To put it briefly, so long as can be defined as the antifriction bearing when possessing outer lane, inner circle, rolling element. According to the shape of the rolling element, the antifriction bearing is divided into ball bearing and roller bearing two big class.
The lubricated eye of the antifriction bearing reduces the internal friction of the bearing and abrades, prevent burning and glueing; Lengthen its life time; Discharge the frictional heat, cool, prevent the excessive heating of the bearing, prevent lubricating oil from wearing out; Also prevent foreign matter from invading within the bearing, or prevent getting rusty, result of corrosion.
Bearing lubricated method, is divided into lipoprotein lubricating and oil lubrication. In order to make the bearing well give play to the function, at first, will be chosen suitable service conditions, lubricated method to use purpose. If only consider lubricating, the lubricating property predominant of the oil lubrication. However, the lipoprotein is lubricated can simplify the structural specialty around of the bearing, lubricate the lipoprotein to compare with pros and cons of the oil lubrication. Should pay special attention to consumption while lubricating, no matter oil lubrication or lipoprotein is lubricated, it influences the bearing life-span that quantity is lubricated too few insufficiently, quantity will produce great resistance too much, influence the rotational speed.
Install and safeguard
Pay attention to the main point
Guarantee from using the angle the bearing should pay attention to the following several points to work reliably:
1,Improve lubricated quality, control the pressure, temperature and flowrate of the engine oil, strengthen the engine oil to filtrate.
2,It accords with specified fuel and lubricating oil to adopt.
3,Control the temperature state of the diesel generator set, it is all unfavorable to work in with overheated supercooling cases. Leng Tian, the diesel engine should be preheated first before start, and rotated the crankshaft by hand to make the engine oil enter and grit the surface.
4,The bearing, journal surface condition and geometric shape should get the assurance strictly.
5,The bearing clearance should be appropriate, the generating set over assaults, too lubricate badly small, may burn tiles.
