What is the axial series momentum of plain bearings?
Rolling bearings are widely used in various machines and institutions because of their small friction resistance, quick start-up, high efficiency, high rotating accuracy, simple lubrication and easy assembly and disassembly. Rolling bearings are standard parts, which are produced by the bearing factory in large quantities, and the designers can choose them directly according to their needs. 14.2.2 rolling bearing type and characteristics, according to the shape of the rolling body, rolling bearings are divided into ball bearings and roller bearings. According to the main direction of load bearing can bear, can be divided into radial bearings (mainly bear radial load, thrust bearing) (axial load), thrust bearing (can bear radial load and axial load).
The working surface of the rolling bearing must be ground and polished so as to improve its contact fatigue strength. The holder is made of multi - purpose low carbon steel plate by stamping forming method, and also can be made of non-ferrous metal or plastic material. In order to meet some special requirements, some rolling bearings must be attached to other special components or to adopt special structures, such as bearings without inner ring or outer ring, with dust-proof sealing structure or with stop rings on the outer ring.
For the rolling bearings and plain bearings of motors, the vibration limits and the measuring methods, please give me the axial distance The inner and outer rings and rolling bodies of rolling bearings should have higher hardness and contact fatigue strength, good wear resistance and impact toughness. General use of special bearing steel manufacturing, commonly used materials are GCrl5, GCrl5SiMn, GCr6, GCr9, etc., after heat treatment, hardness up to 60-65HRC.
