Guangzhou city bearing factory bearing is to show how to the working principle of high temperature resistant if you are looking for high temperature bearing has a deep understanding of, you will find that the bearing is indeed a very ingenious mechanical parts.
Although very simple, but it is very clever days with the characteristics of the data.
Every local bearing load bearing pressure load.
Yes, this is the bearing of a local delicacy.
In a simple deep groove ball bearing as an example.
Inside and between steel balls and steel ball and outer pressure load.
Data can accept compressive stress must be much higher than tensile stress, thus bearing raceway or ball can accept high compressive stress.
Bearing the high temperature bearing how to accept high temperature then?
First of all, why the temperature to rise?
Bearing work, between the roller and outer ring, will produce contact friction between roller and inner circle.
Friction will generate heat, and heat will be absorbed by the bearing parts, and the temperature will rise.
Friction is bearing parts bearing in normal working conditions of heat source temperature is really high?
The answer can not, then when the bearings work continuously to reduce the temperature of the bearing?
A, how to reduce the generation of heat?
Smooth, reduce the friction coefficient between the contact parts.
Reduce the friction coefficient, heat will be reduced.
Bearing is working, it is necessary to add smooth smooth grease or oil talents to work.
In addition, oil bearing heat will also be a smooth away.
With the increase of bearing temperature, when the temperature around the bearing temperature is higher than other parts, by conduction and radiation heat transfer to other media.
The higher the temperature, the more heat through heat conduction and radiation distribution.
When the temperature reaches a certain value, the heat generated by the friction with the equal distribution of heat.
This is due to the bearing in thermal equilibrium, that is, the temperature of the bearing will be stable and no longer increases.
Plain bearing can accept the high working temperature, usually the use of common information bearing life should not exceed 120 ℃, otherwise it will affect the use of the bearing life.
If the temperature above 120 ℃, should think of other solutions.
