SKF angular contact ball bearing wear at work

As clearance refers to the bearing clearance are in a state of stable work operation. Appropriate work clearance will help to boost the closed system research, also did not consider the correlation of various factors, the calculation results and the actual deviation is bigger, in fact, SKF bearing operating temperature field for non-uniform, and the three are interconnected. Generally, if the correct use of bearings, can be used to achieve fatigue life. But there will be unexpected injury prematurely, not resistant to use. This early damage, and fatigue life, it is called the fault or the quality using the limit of the accident. Much due to the installation, use, do not pay attention on the lubrication, intrusion of foreign bodies from outside, to the shaft, shell heat affected study enough. Bearing work, there are lots of factors in affecting the clearance mainly have the temperature change of the angular contact ball bearing, centrifugal force and cooperate, etc. In the process of work, because of the influence of centrifugal force, temperature and make it work clearance changes, from time to time with the influence of three factors are not isolated, but interrelated. About bearing damage status, such as: roller bearing ring, guard card injury, as a reason to consider, lack of lubricant, not suitable for, for the defect of oil discharge structure, the invasion of the foreign body, bearing installation error, the deflection of the shaft is too large, also can have these reasons. The adjustment of the bearing stiffness and the alignment hole and bearing seat must have enough stiffness, and on the same axis bearing hole must maintain strict misalignment. In addition, may adopt reactivity of diameter, the trigger roller sports wedge and overload. By positioning device positioning, SKF bearing the installation, should check whether the snap ring is good, whether can shoulder smooth level off, the surface of the presence of impurities dirt, etc. Through the test run to find is, in the process of the bolt bearing cap and tighten, constantly rotating angular contact ball bearing makes it find itself should is in the rotation, tighten the bolt torque by the regulation. In the process of screw shaft bearing cover again, constantly rotating shaft, bearing should be looking for is on its own. If the bearing rotating lightweight flexible, no binding, that is, has been looking for is, can be in accordance with the provisions, torque in 2 ~ 3 times evenly tighten bearing cover bolts. Intermediate support bearing so should adjust the drive shaft. Therefore, investigation of SKF bearing damage, only the real reason is hard to come by injury. But, if you know the angular contact ball bearing using mechanical and conditions of use, bearing the surrounding structure, to get hold of before and after the accident, combined with several damage status and causes of bearing, can prevent the similar accident happen again.
