For bearings of this type, the raceways on the outer and inner rings have a conical surface along which the tapered rollers move together with the cage. This design allows tapered bearings to carry combined loads - radial and axial. The axial load capacity is determined by the contact angle. The larger the angle, the higher the axial load capacity of the bearing. The value of the contact angle is determined by a coefficient; the greater the value of this value, the greater the contact angle. Consequently, the bearing's ability to carry axial loads increases.

The design of tapered roller bearings is dismountable. The block, which consists of a cage, a set of rollers and an inner ring, can be installed separately from the outer ring.

The conical surface of the bearing tracks allows for optimal load distribution in the contact area between the rollers and the tracks on the rings.

The geometry of the ends of the rollers and guide flanges contributes to the correct formation of a lubricating film between the flanges of the bearing rings and the ends of the rollers in their contact area. The above advantages increase the operational reliability of bearings and reduce sensitivity to misalignment.

Conical roller bearings must be adjusted depending on the size of the axial clearance in them. Visually, the need for bearing adjustment is determined by rocking the flange on the bevel gear shank. If swaying is felt, the bearing must be tightened. Taper and roller bearings are tightened by removing the adjusting shims or by grinding the adjusting washers, for which the bearing is disassembled. The number of shims to be removed is determined by the size of the gap formed and the amount of preload required.  

Tapered roller bearings (see Fig. 12.8, d) are also designed to withstand radial and axial loads. Compared to angular contact ball bearings, they have a higher load capacity, the ability to separately mount the inner (together with rollers and cage) and outer rings, and also the ability to withstand small shock loads. The disadvantage of these bearings is their high sensitivity to misalignment and relative misalignment of the rings, so they require rigid shafts, precision boring of the housings and careful installation. When a double-sided axial load is applied, pairwise installation of bearings is used.  

Tapered roller bearings are rejected when the rollers protrude beyond the outer ring.  

A tapered roller bearing (Fig. 13.12 6) with tapered rollers absorbs radial and axial loads ( angular contact bearing), has a large load capacity and does not allow angular displacement of the rings. If the contact angle is a45, then the bearing is called thrust-radial.  

Tapered roller bearings are mounted separately: the inner ring of the bearing with rollers and cage is pressed onto the shaft, and the outer ring is pressed into the housing. Regulate tapered bearings using gaskets of calibrated thickness. The quality of bearing assembly is determined by axial play, as well as by the amount of torque required to rotate the shaft after assembly.  

Tapered roller bearings (27, 28) are used to carry high radial and axial loads.  

Tapered roller bearings are used in gears loaded simultaneously in the radial and axial directions.  

Tapered roller bearings of the roller axle operate in liquid lubricant, which is poured into the internal cavity of the balancer head.  

Tapered roller bearings of various mechanisms and gears are adjusted by selecting gaskets for the covers. The cover is attached to the mechanism housing with bolts tightened to capacity. After correct adjustment, when swinging the mechanism parts by hand, there should be no play in the bearings. The part in the bearings should rotate easily and smoothly, without jamming.  

Tapered roller bearings (for example, aircraft landing gear wheels) experience wear on the end surfaces of the rings and rollers or collapse of the thickened part of the rollers. Re-tensioning during assembly is also possible for ball bearings, especially thrust bearings. This results in uneven wear or chipping of material from the rolling surfaces. It is also possible for the rings to break in the event of abnormal loading of a tightened bearing during its operation or directly during assembly of the unit.  

Tapered roller bearings are mounted separately; in this case, the inner ring with rollers and a separator is pressed onto the shaft, and the outer ring is installed in the housing.  

The installation of tapered roller bearings in a cup is often used for cantilever mounting of a gear shaft in bevel gear units.  

The peculiarity is that these details are designed for a traverse from a single one, taken from the factory.
An axle is pressed out of it (the body traverse), the traverse is turned over, and the landing plane is machined bearing, she (the plane on which it rests bearing) must be strictly perpendicular to the axis of the steering column, because
cone bearings They are very afraid of distortions.

RuS: for Taras - He's right!
You can drive, but the handling is good on a single vehicle!
The standard is like a felt boot!
Where he turned and moved.
For a chaper this may be great, but for me on the street it doesn’t work at all.
Take a ride on the Jap as he delves into the packages and turns.
You can see the difference at the same time!
And colossal.
Dnepr can also be made, but it is necessary to change the angle of the steering column.
Can you give your steering wheel freely at speed?
Figurines!
It goes straight to the right.
But I can!
What really worked for me was cutting off the back part and aligning it with the base.
Therefore, like a column, it looked in one direction, and the rear wheel in the other.
Well, traverses from Java.
Now I can even throw the steering wheel at 100 with peace of mind!
It stands like a stone.

Single row conical bearings are the most common and widely used in the automotive industry and mechanical engineering.
They are able to withstand unilateral axial and radial loads together, and also withstand impact loads.
They consist of outer and spiritual rings and rollers held by a separator.
The design allows the rings to be mounted separately, and during installation and operation it is possible to adjust both axial and radial clearances.
At times, this image is used without a spiritual ring with raceways on the shaft, to reduce the dimensions of the structure.
Also for complex part designs, bearings of this type are installed in pairs.

It is worth noting that single-row conical bearings, are often used for unilateral axial loads and radial loads.
At the same time, separate, sequential installation of the rings is also possible, thanks to which the axial play can be adjusted properly, as well as the radial clearance.
This is very important, because it simplifies both operation and installation bearing.
In addition, single-row conical bearings can be accepted with pre-tension, and accordingly, their installation can be carried out in one support.

And most importantly, understand that in order to bearings work satisfactorily, it is necessary that they are always subject to a minimum load, especially in cases where bearings work for maximum speeds, and accordingly, friction in lubricants can negatively affect the slipping of balls along specialized tracks.
