Bearing raceway noise limit speed? See solution bearing manufacturer

Bearing raceway noise limit speed? Look at bearing manufacturer solution source: bearing | last updated: - 2020 07 - 27 bearing very bearing raceway noise limit speed? See solution bearing manufacturer of rolling bearing limit rotational speed is under certain load, lubrication condition allows the highest speed, and bearing type, size, load size and direction type, lubricants and lubrication method, clearance, cage structure and cooling condition, and many other factors. Factors that affect the limit speed are: load size, load types and direction, lubricants and lubrication. Experience has shown that improve the manufacturing precision of the bearing, appropriate increase the clearance of bearing, the use of special materials and structure of the cage, also can improve the bearing limit speed. The cause of the high bearing temperature are: lubricating oil quality does not conform to the requirements or metamorphism, lubricating oil viscosity is too high; The assemble tight ( Inadequate clearance) ； One-way bearing assembly too tight; Bearing race in internal rotation shaft or housing; Too much load; Bearing cage or rolling body fracture, etc. The functioning of the rolling bearing in the work to allow a slight noise, if you have any abnormal noise or excessive noise or sound, suggests that the bearing failure. Cause noise of rolling bearings is more complex, one is the bearing inner and outer surface wear. Due to this kind of wear and tear, damage and shell, a one-way bearing and the bearing axis of cooperate relationship, lead to axis deviation from the correct position, when axis at high speed movement produces sound. When the TIMKEN bearing fatigue, its surface metal flake, also can produce sound make bearing radial clearance increases. In addition, the bearing lubrication, forms the dry friction, and bearing broken etc all make abnormal noise. After bearing wear loose, loose cage damaged, also can produce sound bearing damage. Rolling bearings to remove check, according to the damage of bearing judging one-way bearing failure and damage reasons. The so-called pressure constant is the use of helical spring pretightening, disc spring, give appropriate preparation method of the bearing. When use, even though the bearing changing the relative position, loading method in advance. When use bearing what type of seal? , it will even the change of relative position, preload can maintain.
