Bearing failure caused by the specific factors

Bearing in use process, many factors can lead to bearing can't normal use, also is the failure of bearing, what are the specific factors that cause bearing failure? China bearing network according to understand, know the main bearing failure are the five factors. First, electric corrosion caused by the failure when the current through the rolling element from a race to another race, will cause corrosion or edm. The extent of the damage depends on the size of the energy and the length of time, but the result is often the same: roller and roll on electric corrosion pits, rapid degradation of lubricant and bearing failure in advance. In order to prevent damage caused by the electric current, usually used in the drive end bearing insulation. SKF provides two types of insulation bearing: INSOCOAT bearings and hybrid ceramic bearing insulation. Second, insufficient lubrication and pollution caused by the failure if you have any impurities, lubricant viscosity is not enough or into causes between roller and raceway of lubricating oil film thinning, leading to the surface of metal and metal contact. To avoid this situation, we should first check whether to use the correct lubricant, and check whether add lubricating and dose is suitable for the applications. If the lubricant contains pollutants, check the seals and determine whether to need to change or update it. According to different applications, in some cases, the need to use the high viscosity of lubricant to increase the oil film thickness. Third, vibration caused by the failure of transport if not firmly fixed motor rotor shaft, inside the bearing clearance may produce vibration, damage to the bearings. Also, if the motor is in static state when subjected to external vibration for a long period of time, the bearing will be damaged. The following ways can be used in the process of transportation will be bearing is fixed: first application a u-shaped flat steel bending axial lock shaft, carefully to drive the ball bearing preload, and then use a bind to bearing radial load. If let stand, extended to turn the rotor shaft on a regular basis. Fourth, resulted from the improper installation and assembly is installed in the common errors include using a hammer or other similar tool install half coupling or pulley to the shaft not excessive tension, unbalanced, belt, etc. , resulting in bearing overload. In order to prevent this happening, can use SKF shaft alignment tools and Microlog vibration analyzer and other precision instruments to check on and vibration, and when installing a bearing using the appropriate tools and methods. Fifth, the failure of inadequate bearing load bearing always needs a minimum load to work properly. Inadequate bearing pre-load damage can be characterized by roller and roll of adhesive wear. In order to prevent this kind of circumstance happening again, please make sure that places a big enough on the bearing of the external load. Cylindrical roller bearing is often applied to the heavier load, bear in mind that this is particularly important. This method is not applicable to preload bearings. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
