T.AR tandem thrust bearing in series

T.AR tandem  tandem thrust bearing is a thrust bearing that supports load in a single direction:

It consists of two to eight thrust cylindrical roller bearings arranged in series, and has a middle ring. The elastic diaphragm system can evenly distribute the force to each thrust cylindrical roller bearing. The roller is a tried-and-tested cylindrical roller in the product catalog. Cylindrical rollers are guided by cages. Cages are made of brass, aluminum or nylon. Bearing rings and spacers are made of hardened steel. For high performance types, bearing rings made of high performance steel are used. The speed, permissible temperature range and design details of the T.AR series series thrust bearings can be found in the quotation drawing.

Tandem bearing has the following structural types:

Basic type tandem bearing FIG. 2 is connected with the shaft ring, seat ring and roller cage assembly by elastic spacers. This type of bearing is separable structure, parts can be detachable, it must be carefully installed and disassembled in accordance with the numbering order provided by our company

FIG. 3 Serial bearing with shaft type of our company's product is a variant structure bearing. A shaft is threaded through the inner hole of the basic serial bearing, and the bearing is fixed on the shaft with an elastic lock ring. The bearing parts can not be separated, the overall loading and unloading when used, very convenient.

FIG. 4 shows that sleeve is covered on the outside of basic type tandem bearing, which is generally loaded and unloaded in use.

Tandem bearings have the following characteristics:

The Tandem thrust cylindrical roller bearing provided by Luoyang Jinshuo Precision Bearing Co., Ltd. has the characteristics of small radial section size, compact structure, large axial load capacity, uniform roller load in each row, low wear resistance, small vibration and noise, long life and customizable.

Tandem thrust roller bearings are mainly used in the following fields:

Series bearing has been widely used in gear box

Suitable for rubber and plastic, PVC single screw and double screw extruder industry; Grain, snacks, feed bulking machine industryConical screw extruder rubber and plastic industry parallel twin screw extruder oil press processing industry screw oil press welldrilling oil production deep hole drilling machine pipe laying and pulling machine extruder picture 5

Tandem bearing assembly:

When the series bearings produced by our company leave the factory, the sequence is engraved on the bearings. All parts must be assembled in the prescribed sequence. The assembler will find the corresponding assembly instructions in the package.

Bearing parts match each other with high accuracy and are therefore not interchangeable in most cases. If the correct arrangement must be followed at the time of assembly, the relevant bearings will be marked accordingly.

When installing or removing bearings, do not use hammers or other heavy tools .

Design of bearing layout:

When T.AR series thrust bearings are used to design the thrust bearing arrangement of gearbox, many factors must be considered in the structural design.

Tandem bearing preload:

T.AR series thrust bearings in series must bear preload of 1% of basic rated dynamic load. As a result, a minimum load can be provided to avoid skidding damage during no-load operation. In addition, it can ensure that the stiffness is within the linear range of the characteristic curve. The positioning of bearings with respect to the second shaft (the cochlear shaft) is simplified.

Tandem bearing load:

The common loads during the operation of extruders form the design basis of T.AR series series thrust bearings. The maximum axial load Fa max series thrust bearing has been specified in the quotation drawing. The bearing is not allowed to exceed the load during operation.

Tandem  bearing deformation:

For twin-screw extruders, the engagement between the screws must be ensured throughout the working rangeProcess gap. The deformation of the T.AR series series thrust bearing must be observed together with the second thrust bearing and matched with it. This is especially important when bearings of different designs are used on the two output shafts.

Tandem  bearing radial guide:

The output shaft consists of centripetal bearings (such as needle roller bearings or SL series single row full cylindrical roller shaftsCarry out radial guidance.

Tandem  bearing lubrication:

To ensure adequate heat dissipation and lubrication, the T.AR series series thrust bearings are lubricated with circulating oil. Lubrication systems are usually equipped with a lubricating oil filter and cooling unit.

 

Tandem  bearing mounting fit:

When installing T.AR series series thrust bearings, it is recommended to adopt f6 fit tolerance for shaft and F7 fit tolerance for bearing seat hole. In order to achieve uniform load distribution, bearings shall not be tilted after installation. Strict geometric tolerances of adjacent structures must also be observed.

Tandem  bearing customization:

 

Series bearings are available in two, three, four, five, six, seven or eight rows depending on the screw center distance, spacing and load size of the sample center. We also accept series bearings of sizes and structures other than samples. If you need non-standard size, our company can also support customization.
