- Different structures
The fundamental difference is that the structure is different: the inner and outer rings of tapered roller bearings have a tapered raceways, and tapered rollers are installed between the raceways. The tapered roller bearing is guided by the large retaining edge of the inner ring, and is designed to intersect the apex of each conical surface of the roller rolling surface with the inner and outer ring raceway surfaces at a point on the center line of the bearing. The rollers of cylindrical roller bearings are usually guided by two retaining edges of a bearing ring, belonging to separable bearings. The cage roller and guide ring form a combination that can be separated from the other bearing ring.
- Different force ranges
The scope of the stress of the two is different. The cylindrical roller bearing and the tapered roller bearings on the single -gear edge can withstand the radial force and can also bear a single direction axial force. Although it can withstand larger radial force, it cannot withstand axial force; the cylindrical roller bearings on the single -block side are different. It can withstand the axial force of the radial force and a single direction. The double row and four row tapered roller bearings can withstand larger radial force and larger two -way axial force. The cylindrical roller bearings of the single -row and double row, the cylindrical roller bearings with the flange ring, and the tapered roller bearings are very fast.
3. Different accuracy
Precision tapered roller bearings, cylindrical roller bearings, and tapered roller bearings have much higher accuracy than other bearings. The accuracy of single row and double row cylindrical roller bearings is better than that of single row tapered roller bearings.
4.The scope of the use of tapered roller bearing and cylindrical roller bearings
4.1 The main purpose of cylindrical roller bearings The axis shaft box, diesel engine crankshaft, large motor, machine tool spindle, car, tractor gearbox, etc.
4.2. The main purpose of cone roller bearings Building machinery, large agricultural machinery vehicle front wheels, rear wheels, transmission, differential small gear shafts, railway vehicle gear deceleration devices, hot and cold steel rolling machine work rolling, middle rollers, support rollers, rotating kiln gear and deceleration device.
5. Key procedures for cone roller bearings
The newly designed cone roller bearings adopt a enhanced structure. The diameter of the roller is lengthened, the length of the roller is lengthened, and the number of rollers becomes a large number. It uses convex roller to significantly improve the bearing capacity and service life of the bearing. The roller large end face and the large gear side use the sphere and the cone surface to improve the lubrication.
6.Quality assurance
6.1 The choice of raw materials is the most critical link of the bearing. The Chengfeng Bearing is 100%full inspection of each batch of materials.
6.2. The bearing rings and rolling bodies are treated with heat-treated with oxygen free bainite and oxygen free salt to ensure the hardness of the product within 1HRC.
6.3. The end surface of the bearing is machined with double -end surface grinding to ensure higher the end -facial balance difference. The grinding processing uses CNC grinding machine and super fine equipment to ensure that the circularity is within 2 UM and the roughness is within 1um.
