The tapered roller bearing mainly accepts the radial and axial combined load. The bearing bearing capacity depends on the raceway viewpoint of the outer ring; the larger the viewpoint, the greater the bearing capacity. This type of bearing is a separate bearing; The number of columns of the rolling body is divided into single-row, double-row and four-row tapered roller bearings. The single-row tapered roller bearing clearance needs to be adjusted by the user when the device is installed. The double-row and four-row tapered roller bearing clearances are already in the factory according to the product. User requirements are given; no user adjustment is required.
Tapered roller bearings have conical inner and outer ring raceways; tapered rollers are placed between the two. The projection lines of all conical surfaces are agglomerated at the same point on the bearing axis. This depiction makes tapered roller bearings unique It is suitable to accept composite (radial and axial) loads. The axial load of the bearing can be mostly determined by the touch angle α. The larger the α viewpoint, the higher the axial load. The viewpoint size is indicated by the calculation coefficient e. The larger the e value; the larger the touch point of view; the greater the applicability of the bearing to accept the axial load.
Tapered roller bearings are usually separated; that is, the conical inner ring assembly consisting of the inner ring with the roller and cage assembly can be separated from the outer ring (outer ring).
