Prolonging the service life of the self-aligning ball bearing common problems

1. The installation of bearing self-aligning ball bearing is correct, affect accuracy, life and performance. So for the installation of the self-aligning ball bearing design and assembly for fully study the following conclusions, standard of work is usually as follows: do not allow a powerful punch, are not allowed to use hammer percussion bearing directly, not allowed by transfer roller pressure. B using appropriate and accurate installation tools use a special tool, as far as possible to avoid use cloth class and short fiber, things like that. C try to keep the self-aligning ball bearing and the surrounding environment clean dust into the bearing even invisible to the naked eye smile, also can increase the bearing wear, vibration and noise. D to prevent rusting timken bearing directly with the hand take bearing, to fully wash hands sweat. And after coated with the high quality mineral oils, especially in the rainy season and summer to pay attention to rust. 2. Basic condition monitoring bearing in use process, should be regularly switch heart ball bearings run monitoring basic external conditions, such as temperature, vibration and noise measurement, etc. The periodic inspection will find potential problem and stop the machine as soon as possible, to prevent accidental phenomena, make production plan, improve productivity and efficiency of the factory. 3. To bearing lubrication bearing during operation, it is necessary to correct again, self-aligning ball bearing lubrication, to improve its performance. Grease lubrication bearing lubrication method, divided into lubricating oil dominant. However, in order to simplify the bearing grease is about the structure of professional knowledge. Self-aligning ball bearing is a kind of precision mechanical support element, timken bearing users deeply hope perfectly on the host bearing can be used for a predetermined period from damage and keep its dynamic performance, but reality sometimes is not very desirable, sudden bearing failure accident can cause great losses to the user. Through a lot of rolling bearing failure analysis showed that premature bearing short-lived or loss of accuracy, have a plenty of due to improper material defect or manufacturing, but in a considerable extent is because there is no bearings used in strict accordance with the requirements for installation, maintenance, or bearing selection or actual load than the load rating of bearing damaged bearing abnormal reasons, for example, the fatigue spalling of bearing parts to a great extent is because the lubricating oil mixed with impurities. Visible, if you want to achieve precision of rolling bearing has a longer life expectancy and retention period, in addition to the bearing manufacturers to improve product quality, bearing users must use scientific methods and procedures used bearings, otherwise, it is a good bearing will be in bad random died under the conditions of use. Early failure mode of the rolling bearing, mainly has broken, plastic deformation, wear, corrosion and fatigue, is mainly contact fatigue under normal conditions. In some special operating conditions, self-aligning ball bearing can get more than the life of the traditional computing, especially in the case of light load. These special operating conditions is, when the rolling surface ( Track and rolling piece) Can be separated by a lubricating oil film effectively and the surface of the limit of pollutants may cause damage. In fact, under the condition of ideal timken bearing faqs, extending the service life of the self-aligning ball bearing is possible. Inaccurate, operations center offset bearing rings, this space, in order to ensure the automatic adjustment, avoid contact friction of normal operation, otherwise bearing will cause serious harm. 1. Assembly site should be kept clean, no dust. 2. To avoid bearing from dust, moisture and contaminants - Pollutants of timken bearing is bad operation and service life. 3. Check the bearing hole and the shaft with the following: geometry and dimensional accuracy, and cleanliness. 4. For bearing ring mating surface coated with a little oil or a little fat. 5. To ensure that the shaft and bearing hole has a 10 degrees - Guide the chamfering of 15 degrees. 6. Don't be cool bearing: condensation of water can lead to timken bearing and the bearing of mating surface rust. 7. After installation: for bearing loading lubricants, check whether the bearing configuration is working properly.
