Bearing selection considerations of the use of rolling bearing all kinds of machinery, instruments, such as market performance has become increasingly strict, for bearing the required conditions, the performance is also increasingly diverse.
In order to from a large number of structure, size, choose the most suitable bearing, need study from various angles.
When choosing bearing, generally, considered as a shafting bearing arrangement, installation, remove the difficulty level of, bearing, size allowed by the space and marketability of bearing, roughly defines the structure of the bearing.
Secondly, comparative study on various mechanical design life of the bearing and the bearing of a variety of different endurance limit bearing has to be decided.
When choosing bearing, tend to be only consider the fatigue life of bearing, the aging by grease and grease, wear life, noise, etc. Also need to be fully research.
Furthermore, according to different purposes, it is necessary to select precision, clearance, cage structure, grease, etc. , as a special design of the bearing.
However, choosing bearing no certain order, rules, consideration should be given priority is to bearing the required conditions, performance, most related matters, especially the actual.
Pieces pieces bearing conditions, the performance required by the conditions of use in pieces, environmental conditions, dimensions of bearing installation pieces pieces of certain bearing allowed by the space load in pieces pieces size and direction of vibration and impact of rotating speed, bearing limit speed mixer pieces inclined axial direction of the inner ring and outer ring of the fixed and bearing pieces pieces with column loading and unloading easy noise pieces pieces, torque rigid economy marketability, decided to use mechanical pieces bearing structure, the arrangement and design life pieces pieces equivalent dynamic load or equivalent static load rotating speed mixer allows static mixer allows axial load (load coefficient
Under the condition of cylindrical roller bearing)
Decided to pieces bearing size rotary pendulum pieces pieces of precision high-speed rotating torque change use note: rolling bearings are precision components, its use should be measured accordingly.
No matter how high performance bearing use, if use undeserved, will not get the desired performance.
Use of bearing the note below.
1.
Keep the bearing and the surrounding clean.
Even the eyes can't see the little dust, will also bring bad influence to the bearing.
So, keep the surrounding clean, dust from invading bearing.
2.
Carefully use.
In use for bearing strong impact, will produce scar and creasing, become the cause of the accident.
Severe cases, can crack, fracture, so must pay attention to.
3.
Use the appropriate operating tools.
Avoid to existing tools to replace, must use the appropriate tools.
4.
To pay attention to the corrosion of the bearing.
Operation of the bearing, hand sweat will become rusty.
Pay attention to the operation with clean hands, it is better to try to bring gloves.
For as long as possible in good condition to maintain the performance of the bearing was required to maintenance, repair, in order to prevent accident arrangement to ensure the reliability of operation, improve the productivity and economy.
To maintain the best conditions of mechanical operation of the corresponding operation standard, on a regular basis.
Content includes monitor running status, supplement or replacement of lubricants, remove the check on a regular basis.
As maintenance issues in the operation, have bearing the rotation of the sound, vibration, temperature, the state of the lubricants and so on.
