What is Tapered roller bearings?

wallpapers News 2021-10-28
Tapered roller bearings refer to radial thrust rolling bearings with tapered rollers as rolling elements. There are two kinds of small cone angle and large cone angle. The small cone angle mainly bears the combined radial and axial load based on the radial load. It is often used in double use, reverse installation, the inner and outer races can be installed separately, and the radial and axial clearances can be adjusted during installation and use; The large taper angle mainly bears the combined axial and radial load based on the axial load. Generally, it is not used to bear pure axial load alone. When configured in pairs (the ends of the same name are installed relative to each other), it can be used to bear pure radial load.
Tapered roller bearings structural features
The type code of the tapered roller bearing is 30000, and the tapered roller bearing is a separable bearing. Under normal circumstances, especially in GB/T307.1-94 "Rolling Bearing Radial Bearing Tolerance", the tapered roller bearing outer ring and inner component can be used interchangeably in 100% of the size range.
The angle of the outer ring and the diameter of the outer raceway are the same as the outer dimensions and have been standardized. It is not allowed to change during design and manufacturing. As a result, the outer ring and inner component of the tapered roller bearing can be interchanged worldwide.
Tapered roller bearings are mainly used to bear combined radial and axial loads, mainly radial loads. Compared with angular contact ball bearings, the bearing capacity is large and the limit speed is low. Tapered roller bearings can withstand axial load in one direction and can limit axial displacement of the shaft or housing in one direction.
Tapered roller bearings applications
Tapered roller bearings are mainly subjected to combined radial and axial loads based on the radial direction. The bearing capacity depends on the raceway angle of the outer ring, the larger the angle, the greater the bearing capacity. This type of bearing is a separable bearing, which is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rolling elements in the bearing. The clearance of single-row tapered roller bearings needs to be adjusted by the user during installation; the clearances of double-row and four-row tapered roller bearings have been set at the factory according to user requirements, and no user adjustment is required.
The tapered roller bearing has a tapered inner ring and an outer ring raceway, and the tapered rollers are arranged between the two. All the projection lines of the cone surface converge at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for bearing compound (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle α; the larger the angle α, the higher the axial load capacity. The size of the angle is expressed by the calculation coefficient e; the greater the value of e, the greater the contact angle, and the greater the applicability of the bearing to bear the axial load.
Tapered roller bearings are usually separated, that is, the tapered inner ring component composed of the inner ring with roller and cage components can be installed separately from the tapered outer ring (outer ring).
Tapered roller bearings are widely used in industries such as automobiles, rolling mills, mining, metallurgy, and plastic machinery.
