The reasons for the failure of SKF bearings are often multi-factors. All influencing factors in the design and manufacturing process will be related to the failure of the bearing, which is not easy to judge by analysis. In general, it can be considered and analyzed from two aspects: use factors and internal factors. The use factor mainly refers to whether the installation adjustment, use and maintenance, maintenance and repair meet the technical requirements. Installation conditions are one of the most important factors in the use of factors. Bearings often change due to improper installation, resulting in changes in the stress state between the various parts of the entire set of bearings. The bearing runs under abnormal conditions and fails prematurely. According to the technical requirements of bearing installation, use, maintenance, and maintenance, monitor and inspect the load, speed, working temperature, vibration, noise and lubrication conditions of the bearing in operation. If an abnormality is found, immediately find the cause and make adjustments to make it Back to normal. In addition, it is also very important to analyze and inspect the quality of the grease and the surrounding medium and atmosphere.

    The internal factors mainly refer to the three major factors that determine the quality of the bearing, such as structural design, manufacturing process and material quality.

    First of all, with reasonable structural design and advanced nature, long bearing life will be achieved. The manufacture of bearings generally involves multiple processing procedures such as forging, heat treatment, turning, grinding and assembly. The rationality, advancement and stability of each processing technology will also affect the life of the bearing.

    Among them, the heat treatment and grinding process that affect the quality of finished bearings are often more directly related to the failure of the bearing. In recent years, studies on the deteriorating layer of the bearing working surface show that the grinding process is closely related to the bearing surface quality.

    The metallurgical quality of SKF bearing materials used to be the main factor affecting the early failure of rolling bearings. With the progress of metallurgical technology (such as vacuum degassing of bearing steel, etc.), the quality of raw materials has been improved. The proportion of raw material quality factors in bearing failure analysis has dropped significantly, but it is still one of the main factors affecting bearing failure. The proper selection of materials is still a factor that must be considered in bearing failure analysis.

    The main task of SKF bearing failure analysis is to find out the main factors causing bearing failure based on a large number of background materials, analysis data and failure modes, so as to propose improvement measures to extend the service life of the bearing and avoid sudden occurrence of the bearing. Early failure of sex.

    Each type of SKF bearing design exists in a common removal process. Regarding the smaller bearings, there is a time that the driver can assist in the removal of the bearings. If the operation is not done properly, it can protect the bearing, shaft or shell, requiring noble training. As a result, heavy and light industrial bearings dedicated a small amount of profit injection. When a new or reformed bearing is absorbed, it is not packaged until the preparation device is in use. This is especially used in light industry, where the task environment is often stubborn, the load is heavy, and dirt and purification are rare areas.

    Heat lamps or other heating facilities can be used. Even wet or unprotected hands or large numbers of chemical gloves kept in contact can cause seal carving in a small sea area, which can cause bearing fatigue. Regarding the installation of close cooperation, or press, or has been locked in the center of the first degree shaft, there is no machine to remove the bearing puller, the inner ring of the bearing can be heated to increase the relocation. If the torch is once, it will change the function of the bearing steel and the bearing must be abandoned.

    The service life of any SKF bearing is largely derived from its absorption for protection and maintenance. SKFN bearing storage has special anti-erosion coating bearings to choose from, but most of the bearings do not have anti-erosion materials. Bearing performance can cause noble downtime, facility protection and malfunctions. This includes bearing storage, cleaning, cleaning, testing and installation. The idea of ​​anti-conflict bearing applied to all.

    Bearings here are not subject to high humidity or sudden and violent measurement changes that can cause condensation in the sea. There is no tube bearing type, and the bearing must be particularly carelessly removed. There is no need for indirect storage on lime ground, where condensed water can be collected and bearing. In order to achieve the functions of high facilities and operate reliably with minimum protection profits, accurate solutions must be followed. Bearings that are being resolved and stored must be taken carelessly to ensure that they will not rust or corrode.

    Formation and reform of SKF bearings are shipped with a protective insulating layer, usually in a protective cover paper or other packaging, and shipped in a suitcase or wooden box. Always put bamboo paper or Xu, if not, in the roller and tapered roller bearing cup competition plastic sheet. The tea trays or bearings on the store shelves are the main components of the once secondary light industry facilities.
