The structure of self-aligning roller bearing makes it have the function of self-aligning, which can bear both radial load and bidirectional axial load, and has strong impact resistance. Main uses: papermaking machinery, rolling mill gearbox bearing seat, rolling mill roller, crusher, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reducer, etc. Many people do not know how to install self-alting roller bearings, afraid of bad installation affect the use of installation and what matters need to pay attention to, the following for you to explain:

How to install:

Self-aligning roller bearing A bearing equipped with drum rollers between an inner ring with two raceways and an outer ring with a spherical raceway. The center of curvature of the raceway surface of the outer ring is consistent with the center of the bearing, so it has the same aligning function as the automatic aligning ball bearing. When the shaft and shell are flexed, it can automatically adjust the load and the axial load in two directions. Large radial load capacity, suitable for heavy load, impact load. The inner diameter of the inner ring is the bearing with taper hole, which can be installed directly. Or the use of fixed sleeve, disassembly cylinder installed on the cylindrical shaft. The cage uses steel plate stamping cage, polyamide forming cage and copper alloy turning cage.

For self-aligning bearings, when the bearing with shaft is loaded into the shaft hole of the box body, the middle mounting ring can prevent the outer ring from tilting and rotating. It should be remembered that for some sizes of self-aligning ball bearings, the ball is protruding from the side of the bearing, so the middle mounting ring should be recessed to prevent damage to the ball. A large number of bearings are generally installed by mechanical or hydraulic pressing method.

For separable bearings, the inner and outer rings can be installed separately, which simplifies the installation process, especially when both the inner and outer rings need interference fit. When the shaft with the inner ring installed in place is loaded into the bearing box with the outer ring, attention must be paid to check whether the inner and outer rings are correctly aligned to avoid scratching the bearing raceway and rolling parts. If cylindrical and needle roller bearings have inner rings without flanged edges or inner rings with flanged edges on one side, it is recommended to use mounting sleeves. The outer diameter of the sleeve shall be equal to the inner raceway diameter F, and the machining tolerance standard shall be D10. Stamping outer ring needle roller bearings shall be mounted using mandrel.

Through the above explanation, we have a more specific understanding of the installation of self-aligning roller bearings? In the installation process, some things are to pay special attention to, in order not to cause unnecessary trouble, today xiaobian for you to explain.

Four precautions during installation:

1. The installation of self-aligning roller bearings must be carried out under dry and clean environmental conditions.

2. Self-aligning roller bearings should be cleaned with gasoline or kerosene before installation, and used after drying, and ensure good lubrication. Bearings generally use grease lubrication, but also can use oil lubrication.

3. When the self-aligning roller bearing is installed, equal pressure must be applied on the circumference of the end face of the ring to press the ring into it. It is not allowed to hit the end face of the bearing directly with the crucian head tool to avoid damage to the bearing.

4. When the interference is large, oil bath heating or inductor-heating bearing method can be used to install, heating temperature range is 80C-100℃, can not exceed 120℃.

After the installation of the self-aligning roller bearing, it is necessary to test to see if there is any abnormality. If there is noise, vibration and other problems, it is necessary to stop the operation and check in time. Use only after debugging is correct.
