Tapered roller bearings designed for, the inner ring raceway and roller cone vertex together in little bearing outer ring of the central axis, the radial load acting on the bearing, the axial force. Therefore, shall 2 bearings for use, or as pairs of double bearing, double row bearings. Tapered roller bearings are mainly exposed to the radial diameter, axial load bearing carrying capacity depends on the outer ring raceway angle, the angle the more The larger load capacity. This kind of bearing is a separate type of bearings. have tapered inner and outer ring raceways, tapered rollers arranged in between. all conical surface projection lines are at the same point together bearing axis. This design makes tapered roller bearings particularly suitable for bear compound (radial and axial) loads the axial load bearing capacity is mostly determined by the contact angle α; The larger the angle α, the higher the axial load capacity. Angle size to calculate the coefficient of e said; e larger the value, the greater the contact angle, the bearing axial load greater applicability.
Tapered roller bearings are widely used in automotive, mill, mining, metallurgy, plastics machinery and other industries.
Tapered roller type:
· Single row tapered roller bearings: Single row tapered roller bearings are divided into two imperial metric series and series in the design, its inner and outer rings and roller cone point is a point consistent with the bearing center line. Thus, the roller surface in rolled A true sports rely from outside the raceway surface of the resultant force, by the inner wall of the squeeze large boot. This kind of bearing is particularly suitable for radial load and axial load and synthetic load and large load capacity Its larger the contact angle, the greater the axial load capacity. Usually paired with two bearings. Tapered roller bearings are used in automotive rear axle hub, a large machine tool spindles, high-power reducer, rollers and other transportation means. retainer Commonly used stamping cage, but large bearings with cage or cage pivot pin.
· Double row tapered roller bearings: Double row tapered bearings have export-oriented (using double row outer ring) and endo (using double row inner rings) before the factory bearing internal clearance to be fine, the same production model of the part shall use a symbol requires assembly Double row tapered roller bearing roller due to increase the number of columns, radial load capacity increases, while also able to withstand greater two-way axial load mainly used to bear radial load mainly radial and axial joint load effects axial displacement limit the axis (or shell) in both directions, and are therefore useful two-way axial positioning.
· Four tapered roller bearings : Four-row tapered roller bearing consists of two double row inner rings and one double row outer ring and two single row outer ring can bear a greater two-way axial load, but the lower speed limit can limit the shaft (or. housing) in the bearing axial clearance range, can be used as two-way axial positioning axial displacement in both directions can be changed through the inner, the thickness of the spacer between the outer diameter of the bearing to adjust the axial clearance Rated load, mainly used for rolling mill roll neck and other places a large load. This class infiltration of carbon steel bearings, large bearings also support the use of hollow rollers and pin holder, in order to increase the bearing ordered.
