Non-standard bearings manufacturer told you limit speed and the noises of the raceway bearing failure elimination method

Non-standard bearings manufacturer told you limit speed raceway sources of noise and bearing failure elimination method: bearing | last updated: - 2020 08 - 03 non-standard bearing raceway solution rolling bearing noise limit speed limit rotational speed is under certain load, lubrication condition allowed maximum speed, and bearing type, size, load size, type and direction, lubricants and lubrication method, clearance, cage structure and cooling conditions, 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. Pitting fatigue elimination method when the rolling bearing load bearing failure. In contact with the inner and outer surface of roller contact stress will occur. Due to inner and outer ring and rolling body at work have a relative rotation, therefore contact stress for pulsating cycle changes. Produced under when the contact stress exceeds limit value, surface fatigue crack, and gradually extended to the surface, so that the inner and outer ring raceway can roller surface fatigue pitting the accuracy loss of rolling bearing rotation, noise, shock and vibration. So the pitting is the failure forms of rolling bearing
