Taper roller bearings definition
Taper roller bearings can be separated by inner circle roller, keep frame together components and outer ring could separately installed. Roller with groove at the contact point correction of contact wires can reduce stress concentration. Taper roller bearings can withstand the big radial direction load and the axial load. Due to the taper roller bearings can transfer one-way axial load, therefore, to transfer the opposite direction of axial load will need another symmetric installation tapered roller bearings.
Taper roller bearings is the largest single dosage of taper roller bearings. In the front wheel hub in the car, in recent years is also played a small size double row circular cone roller bearings. Four row circular cone roller bearings with cold and used in large heavy machine.
There is a single tapered roller bearing outer ring, predominantly circle and a set of tapered roller by basket shape maintains a multi-faceted into an inner ring components. Outer and inner circle components can be separated, according to ISO tapered roller bearings shape dimension standard regulation, any standard models of tapered roller bearing outer ring or inner ring and outer ring components should be able to share or circle of inner component implementation international swaps. Namely the outer ring is the same except external dimension and tolerance must conform to ISO492 (GB307) specified, inner ring component taper Angle, component cone diameter also must comply with the relevant provisions of the swap.
Usually, single tapered roller bearing outer ring groove taper Angle in 10 ° ~ 19 ° before, can simultaneously under load bearing axial and radial load of joint action. Cone Angle, the larger axial load ability also is larger. Large taper Angle of bearings, rearmounted code add B, cone Angle in 25 ° ~ 29 ° between, it can bear the larger axial load. In addition, single circular cone roller bearings can be adjusted during installation clearance of size.
Double row circular cone roller bearing outer ring (or inner circle) is a whole. Two inner circle (or outer ring) is among similar, small end every lap, clearance is to rely on the thickness of every lap, but also can be used to adjust the isolated circle to adjust the thickness of a double row circular cone roller bearing preloaded.
Taper roller bearings which mainly bear with radial primarily diameter, the axial union load. Bearing outer ring rolling bearing capacity depends on the way Angle, the larger Angle bearing capacity is bigger. These bearings are of separated type bearings, according to the roller bearing in the column number to be mounted, double row and four row circular cone roller bearings. Single tapered roller bearing clearance to users in when installation, adjustment, Double row and four row circular cone roller bearings clearance already in product factory according to user requirements are given, not the user to resize.
Taper roller bearings taper inner ring and outer ring have groove, tapered roller are arranged in between. All taper surface projection lines are the same point in bearing axis reunion. This design makes tapered roller bearings specially suitable for composite (bear) radial and axial load. Bearing axial load ability is mostly decided by the contact Angle is alpha, Alpha greater perspective, axial load capacity is higher. Angle size by calculating coefficient e to say, E is, the contact Angle is, the bigger the bearing axial load applicability is greater.
Taper roller bearings are usually separated type, namely the belt roller and maintains a module of the inner ring of conical inner ring and outer ring (components can conical outer ring) apart installation.
Taper roller bearings are widely used in automobiles, rolling mill, mining, metallurgical, plastic machinery, etc.
