As a professional bearing manufacturer, YOGIE bearing also has the most comprehensive bearing knowledge. The basis of bearing is its own quality. After strict control of bearing steel and cross roller bearing technology, the bearing quality produced by YOGIE bearing is absolutely the best.
But why do you see some damage?
This is mainly because of the use of the attention, not seen because of the quality of the bearing itself caused by the problem.
Aren't people often the most important foundation?
So for the bearing is the same, the basis of the bearing is its own quality, through the bearing steel, cross roller bearing technology and other strict control, the quality of the bearing produced is absolutely the best.
But why do you see some damage?
This is mainly because of the use of the attention, not seen because of the quality of the bearing itself caused by the problem.
The reliability and performance of SKF bearings are judged and predicted through the failure and deterioration of composite bearings, performance and state parameters, and the abnormal parts, causes and degree of danger are identified and judged to determine the comprehensive technology of repair and improvement methods.
Therefore, the fault diagnosis technology of bearing is not a simple fault detection (or monitoring) technology, nor is it a simple point inspection instrumentation.
Correct, rapid and effective acquisition of signals, data processing, manual or automatic identification and judgment.
In order to determine the scientific repair cycle, fatigue and wear life should be tested and estimated according to the mechanism of various faults.
I. selection and control of shaft tolerance and bearing chamber: there is no sense of flexibility in the bearing rotary press block.
If significant rotation is not flexible, then the shaft size is too large and tolerance decreases.
If the bearing is pressed into a hand after the obvious "rustling" in a sense of the steering shaft, it may be too much of a circular shaft or shaft tolerance is bad.
A good shaft control room and bearing tolerance should also be controlled for roundness.
Ii. Bearing assembly mode: as the cross roller bearing for robot is a high-precision product, if the assembly is improper, it is easy to damage the channel bearing, resulting in bearing damage.
Bearing in assembly, there should be a special mold, can not beat, push shaft force can only be a small circle, the press when only under the circle.
The assembly requires the use of pneumatic or hydraulic pressure, in the compression of upper and lower die, outside the national level, if the channel slope will lead to cross roller bearing damage, due to power, leaving the production of bearing guide ring.
Three, the prevention of assembly of foreign bodies: bearings installed rotor dynamic balance is very easy to produce iron scrap inside the bearing before the installation of dynamic balance, so it is best to do dynamic balance.
The bearing is lubricated with some oil or grease, but it is often difficult to control the amount, if the oil or grease in the bearing is left indoors, it is easy to rotate along the shaft to the inside of the cross roller bearing.
Bearing chamber is best not coated with oil or grease, such as non-coating control, no residue in the room.
Four, the prevention of paint rust: paint rust features in a sealed motor, in the assembly of multiple motors sounds good, but in a period of time in the warehouse, the motor becomes very abnormal sound, remove the bearing seriously rusty.
Many manufacturers will be seen as front cross roller bearing problems, and now major appliance manufacturers have realized the problem of varnish.
The main problem is that the insulation paint volatile acid at a certain temperature, humidity metal corrosion and protection, the formation of corrosive substances, corrosion damage caused by channel bearings.
Now the problem is to choose a good varnish, air dry assembly after a period of time.
Five, bearing life is the manufacture, assembly, use closely related, must make every link, in order to make the best national operation of the bearing, so as to extend the service life of cross roller bearing.
