Introduction and structural characteristics of Tapered roller bearings

  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 are mainly used to bear radial load mainly radial and axial joint load. Compared with angular contact ball bearings, bearing capacity, low speed limits. Double row tapered roller bearing outer (or inner) as a whole. Two inner (or outer) face similar small, middle spacer, clearance by adjusting the thickness of the spacer, and can also be used to adjust the thickness of the spacer double row tapered roller bearings preloaded. Tapered roller bearings mainly bear radial diameter, axial joint load. Load bearing capacity Crossed Tapered Roller Bearing  on the angle of the outer ring raceway, the greater the bearing angle Carrying capacity greater. 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. 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 tapered rollers  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. 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 separable bearings, inner and outer rings have tapered raceway. These bearings are loaded according to the number of columns roller into single row, double row and four row tapered roller bearings, such as different structural types. Single row tapered roller bearings can support radial load and axial load in one direction. When the bearing radial load, will produce an axial component, so when you need another can withstand axial force in the opposite direction of the bearing to be balanced.
