Introduction: rolling bearing assembly process - bearing knowledge

Rolling bearing assembly process: rolling bearing parts such as inner ring and outer ring, rolling elements and cage, after inspection, are assembled into the assembly workshop, the process is as follows: part demagnetization, cleaning, internal and external roll < channel> way size group choose don't - and set to check the clearance, riveting cage - final inspection - demagnetization, cleaning and antirust, packaging and shipping department ( Packing and delivery>. Rolling bearing small friction coefficient than sliding bearing, high transmission efficiency. The friction coefficient of sliding bearing is 0. 08 - 0. 12 and the friction coefficient of rolling bearings is only 0. 001 - 0. 005; Rolling bearing is standardization, seriation, generalization, suitable for mass production and supply, use and maintenance is very convenient. Rolling bearing made of bearing steel, and after heat treatment, therefore, the rolling bearing not only has high mechanical performance and longer service life, and can save make prices more expensive nonferrous metals used in the sliding bearing; Rolling bearing internal clearance is small, the processing precision of parts is higher, therefore, high precision. At the same time, can be made by the method of additive load bearing rigidity increase. This is very important for precision machinery; Some of the rolling bearing can bear radial load and axial load at the same time, therefore, can simplify the structure of the bearing pedestal; Because of the rolling bearing high transmission efficiency, less calorific value, therefore, can reduce consumption of lubricating oil, lubricating maintenance more convenient; Rolling bearing can be easily applied to uranium in any direction. Rolling bearing load capacity is much less than the same volume of sliding bearing, therefore, radial size of rolling bearings. So, under heavy load situations and demands radial size, structure compact occasions (such as internal combustion engine crankshaft bearing) , use sliding bearing more; Particularly sensitive to scrap metal and other foreign bodies, rolling bearings bearings once in foreign body, can produce bigger vibration and noise in an intermittent, also can cause early damage. In addition, the rolling bearing due to metal inclusions, etc. Also the possibility of early damage of the easy happening. Even if you don't happen early damage, the service life of rolling bearing also has certain limits. In a word, the life of the rolling bearing is the shorter of the sliding bearing. Rolling bearing compared with sliding bearing, however, each have advantages and disadvantages, each has certain applicable occasions, therefore, they cannot fully replace each other, and to a certain direction, expand their areas. However, due to the prominent advantages of rolling bearings, there is quite a competitor. Today, the development of rolling bearing has become the main mechanical bearing type, more and more widely applied.
