Description

Novel structure of guide bearing and spherical strut of hydraulic generator

The technical field is as follows:

the utility model relates to a hydraulic generator guide bearing and spherical pillar novel structure.

Background art:

when the hydroelectric generating set operates, in order to ensure that the main shaft throw meets the relevant standard, a guide bearing needs to be arranged for supporting, so that the overlarge swinging of the guide bearing is prevented. The spherical support is connected with the guide bearing bush, so that the guide bearing is flexible and reliable in operation. The gap between the guide bearing shoe and the rotating shaft is usually adjusted by adding an adjusting shim between the contact surfaces of the spherical support and the guide bearing shoe. Therefore, in the installation process, the spherical support column needs to be detached for multiple times to install the adjusting gasket, and the operation is complex.

The invention content is as follows:

the utility model aims at disclosing a novel structure of a guide bearing and a spherical pillar of a hydraulic generator, which is convenient to install and disassemble and flexible to adjust. The technical scheme of the utility model is that: the adjusting device is composed of a guide bearing bush, a spherical surface pillar and an adjusting gasket, wherein the spherical surface pillar is inserted into the guide bearing bush, and the adjusting gasket is inserted between the guide bearing bush and the spherical surface pillar to form a whole; the guide bearing bush is made of a steel plate, a U-shaped shallow groove is formed in the back of the guide bearing bush, a fixing hole used for installing a spherical pillar is formed in the position close to the bottom of the U-shaped shallow groove, a threaded hole is formed in the upper portion of the guide bearing bush, a unthreaded hole is formed below the threaded hole, the unthreaded hole extends downwards to reach the fixing hole, and the back of the guide bearing bush is provided with a hole; the spherical strut is made of forged steel; the adjusting shim is made of a steel plate.

Technical effects

1. The utility model discloses the structure is easily processed, simple structure. When the spherical support is installed, the spherical support can be conveniently ejected by using the adjusting holes, and when the adjusting gasket is installed, the spherical support can be directly installed without taking out the spherical support, so that the field installation time can be effectively saved, and the installation efficiency is improved. The U-shaped shallow slot at the back of the guide bearing bush can effectively prevent the adjusting gasket from rotating and falling off.

2. The utility model provides a during the installation of spherical support, compressed gas can release completely through the adjustment hole in the mounting hole, guarantees that spherical support and guide bearing tile laminating are inseparable.

3. The utility model discloses the screw hole at well guide bearing bush top can regard as the lifting eye of guide bearing bush to use.

Description of the drawings:

fig. 1 is a detailed view of a novel structure of a guide bearing bush and a spherical pillar.

Fig. 2 is a sectional view taken along line a-a of fig. 1.

Fig. 3 is a view from direction B of fig. 1.

Fig. 4 is a detailed view of the spacer shim.

The specific implementation mode is as follows:

as shown in fig. 1 and 2, the guide bearing bush 1, the spherical pillar 2 and the adjusting shim 3 form a whole, wherein the guide bearing bush 1 is made of carbon steel, the side edge of the guide bearing bush is provided with a fixing hole 6 for installing the spherical pillar, the upper part of the guide bearing bush is provided with a threaded hole 4, the lower part of the threaded hole is provided with a unthreaded hole 5, the unthreaded hole 5 extends downwards to reach the fixing hole 3, and the back part of the guide bearing bush is provided with a U-shaped shallow groove 7. When the spherical post 2 is mounted, the spherical post 2 is inserted into a fixing hole 6 provided in the guide bearing shoe 1.

As shown in fig. 2 and 3, if the distance between the guide bearing bush 1 and the spherical support 2 needs to be adjusted, a tool can be used to insert downwards through the threaded hole 4 and the unthreaded hole 5, contact the chamfer at the tail of the spherical support, eject the spherical support 2 out of the fixing hole 6, extend the U-shaped groove 7 downwards, insert the adjusting shim 3, and play a role in adjusting the distance between the guide bearing bush 1 and the spherical support 2.

As shown in fig. 4, the adjusting shim 3 is a U-shaped structure made of a thin steel plate, the outer contour dimension of the adjusting shim is smaller than the dimension of the U-shaped shallow groove 7, and the inner contour dimension of the adjusting shim is slightly larger than the diameter dimension of the fixing hole 3.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the claims and their equivalents.
