The basic concept of bearing life

The basic concept of bearing life according to the latest rolling bearing ( 轴承) The fatigue life ( 一生) Theory, a design ( Design) Excellent, excellent material, manufacturing ( zhì zào) Excellent and install the correct bearing, as long as enough to easily subjected to the load ( No greater than the corresponding a durability limit load bearing value) , the material of this bearing ( Material) Will never produce fatigue damage. Therefore, as long as the bearing working environment temperature is appropriate and modest, absolutely no solid dust and harmful gas and water invasion of bearing, bearing lubrication and right fully, lubricant, Effect: can reduce or avoid friction and wear) Absolutely pure without impurities, and not aging metamorphism & hellip; This bearing will run indefinitely ( 旋转) Go on. The significance of this theory is that it not only provides a live equation is more reliable than the ISO predict modern bearing ( 轴承) The life of the tool, and is that it shows all the fatigue life of rolling bearing has a considerable development, 开发) Potential ( Refers to the possibility of individual ability development) , and shows the ways to develop the potential, thus to bearing products ( 产品) Development, quality management, and application of technology ( 技术) Had a profound impact. However, bearing the infinite is only possible under the condition of laboratory; Implementation; And this kind of condition for bearing under certain condition of field use, both difficult to too expensive. The site use ( 使用) Bearing ( 轴承) The work ( 工作) Load is often greater than its corresponding fatigue durability limit load, after the work to a certain time limit, or late or early due to material of contact fatigue limit itself, always produce fatigue spalling and unable to continue to use. Such as cross section thin-walled bearing has realized the extremely thin cross section of the bearing, also has realized the product miniaturization, lightweight. The diversity of products extends its application scope. It is generally divided into glue sealing - RS, iron seal - ZZ, plane, canvas - K, copper - M。 Even if some bearing working load is lower than its corresponding durability limit load, also due to the bearing the problem of pollution of hard to eradicate the wear ( A basic type of component failure) Failure. In a word, the scene of bearing more or less, do not want to be in use sufficient the experiment ( 实验) Room with those conditions ( 挑剑) , and slightly in either condition, can shorten the bearing period are available, and this leads to the life of the bearing problem. Generally speaking, the service life of rolling bearing ( 一生) Refers to the rolling bearing in the actual service conditions ( Including working conditions, environmental conditions and maintenance and maintenance, etc. ) Satisfy the requirement of active, can continue to keep working performance and precision of the specialty service period. Such as cross section thin-walled bearing has realized the extremely thin cross section of the bearing, also has realized the product miniaturization, lightweight. The diversity of products extends its application scope. It is generally divided into glue sealing - RS, iron seal - ZZ, plane, canvas - K, copper - M。 A: on the development of special use ultra clean bearing steel next article: bearing common problem analysis
