Tapered Roller Bearings

Tapered roller bearings taper roller bearings taper roller bearings can be defined by the inner circle, with roller, maintains the components and outer together can be installed. Roller and groove in the fixed contact line contact can reduce stress concentration. Taper roller bearings can withstand the big radial and axial load. Due to the taper roller bearings can transfer one-way axial load, therefore, to transfer in the opposite direction of axial load will need to another with symmetrical installation tapered roller bearings. Taper roller bearings is the largest amount of single row circular cone roller bearings. In front of the car wheel in recent years, also use a small size double row circular cone roller bearings. Four row circular cone roller bearings by in large cold rolling machine, and heavy. Single row circular cone roller bearings, which formed a circle and a group of tapered roller shape by basket on comprehensive into a circle of inner component. Outer and inner circle components can be separated according to ISO tapered roller bearings, size, shape standard of any standard models of tapered roller bearing outer ring components can be inside or outside or inside the circle and the product realization international exchange component. The inner product namely except external dimension and tolerance must conform to ISO492 (GB307 and inner circle) specified taper Angle, component components must conform to the cone diameter and the relevant provisions of the swap. Usually, the single row circular cone roller bearings taper Angle formed in 10 ° ~ 19, can also withstand before ° to load and radial load bearing joint action. Taper Angle is larger, the axial load capacity. Large taper Angle of bearings, the code and B, cone Angle in 25 ° ~ 29 °, it can withstand the larger axial load. In addition, the single row circular cone roller bearings can be adjusted during installation clearance. Double row circular cone roller bearing outer ring (or in) is a whole. Two inner circle (or similar) and small end formed between every lap, clearance is on every lap to adjust the thickness of every lap, can also be used to adjust the thickness of the double row circular cone roller bearings are made. Taper roller bearings by main bear radial primarily diameter, axial load. Bearing capacity depends on the outermost groove Angle, the bearing capacity of the larger Angle. This type of bearings, the separation of bearing of the roller bearings, according to the number of columns and single and double is divided into four row circular cone roller bearings. Single row circular cone roller bearings pre-load adjustment to users when installation, And four row circular cone roller bearings clearance in products according to the requirements of users when given, not the user to resize. Taper roller bearings taper has inner ring and outer groove, tapered roller are arranged in between. All lines of conical surface projection of the same point in bearing axis. This design makes tapered roller bearings specially suitable for composite (bear radial and axial load). Axial load bearing capacity is mostly decided by the contact Angle, Alpha Angle, the greater the axial load capacity is higher. By calculating coefficients of Angle size to e, E, the greater the contact Angle, bearing the applicability of the axial load. Taper roller bearings are usually separated type, namely the belt roller and maintains a component within the circle of inner cone circles with conical outer (components can separate inner). Taper roller bearings are widely used in automobiles, rolling mill, mining, metallurgical, plastic machinery, etc.
