category:tapered roller bearings
tapered roller bearing type code 30000 , tapered roller bearings for the separation of bearings . under normal circumstances, especially in gb / t307.1-94 " rolling bearings tolerance " within the cone are involved in a range of sizes between roller bearing outer ring and the inner component is one hundred percent can be generic interchangeable.
the angle of the outer ring and the outer raceway diameter has been standardized with the same dimensions provides . when allowed to change in design and manufacturing . between tapered roller bearings to cause the outer ring and the inner components are interchangeable generic worldwide .
tapered roller bearings are mainly used to bear radial load mainly radial and axial joint load . compared with angular contact ball bearings , bearing capacity, low speed limits . tapered roller bearings can withstand axial load in one direction , a direction to limit the axial displacement of the shaft or housing .
tapered roller bearings mainly bear radial diameter , axial joint load. load bearing capacity depends on the outer ring raceway angle , angle the greater carrying capacity. these bearings are separable bearings , according to the number of columns bearing rolling elements into single row , double row and four row tapered roller bearings. single row tapered roller bearing clearance to be user adjusted during installation ; double row and four row tapered roller bearing clearance in the factory based on the given user requirements , users do not need to adjust .
tapered roller bearings have tapered inner and outer ring raceways , tapered rollers are arranged between the two. all conical surface projection lines are a little get together with the bearing axis . this design makes tapered roller bearings particularly suitable for the accommodation of combined ( radial and axial ) loads. most of axial load bearing capacity is determined by the contact angle α ; greater the α angle , the higher the axial load capacity . angle size to calculate the coefficient e ; e value , the greater the contact angle , the bearing axial load greater applicability .
tapered roller bearings are usually separated type , that is with roller and cage assembly of components of the inner cone and cone outer ( outer ) installed separately.
tapered roller bearings are widely used in automotive, mill, mining, metallurgy , plastics machinery and other industries.
