Analysis of the structure of common needle roller bearings

Analysis of the structure of common needle roller bearings source: this website the author: the administrator to release time: 2016 - 11 - 10 09:25:28 views: 0 analysis of common needle roller bearing structure in recent years, surrounded by more and more production machinery, because our production demand, need to all kinds of machinery and equipment, and the operation of the machinery and equipment need to use to the bearing, now, we are also gradually increase, the kinds of bearing on these bearings are suitable for all kinds of machinery, now our side composite roller bearing model is also very much, in the face of so much of the needle roller bearings on the market, we should thoroughly analyze their structure, so can we use in production, play out these bearing very big use value. Stamping outer ring needle roller bearing: the needle roller bearing have punch form and two kinds of type, it has no inner ring, needle direct contact with the surface of the shaft, so the machining accuracy and the heat treatment hardness is the same as the bearing inner ring. It is suitable for high speed and overloaded occasions, more commonly used in automobile, machine tool gearbox, etc. Entity ferrule needle roller bearing, the commonly used entity ferrule needle roller bearing is NA and RNA. Advantage is the radial cross section size is small, the radial load bearing large and high speed can meet the requirements for machine tools, automobile gearbox. Combined needle roller bearings: combination of needle roller bearings are entities ferrule needle roller bearing and ball bearing, roller bearing combination. Needle roller and cage component: it is in fact no ring needle roller bearing, it is due to the high temperature in the cylinder, so the bearing resistance to high temperature. This kind of bearing much used in gearbox, motorcycle, automobile connecting rod big, small end, etc. Choose bearing material also want to consider the price of it, and when to use the vacuum smelting or electroslag remelting steel, pay attention to the need to make the WanShanHua lubrication condition, can exponentially improve the fatigue life of bearing can be expected. Understand these different structure of needle roller bearings products, believe that everyone already knows why will have so many bearing products, because the demand is different, we use the performance requirements of these bearings is different also, when we in the purchase of bearing products, or want to choose according to their own use demand more suitable bearing products to use, at the same time we also want to know the usage and maintenance of different bearing products attention points, so you can very good use these bearing products.
