AI Technical Summary
The installation process of bearing brackets and radial bearing segments in traditional axial flow turbine generator sets is complicated and difficult, especially in narrow spaces where it consumes a lot of time, manpower and resources.
Design a radial bearing segment tile and bearing bracket co-sleeve structure for a cross-flow hydro turbine generator. The segment tile is fixed to the bearing bracket by an upper connecting plate and a lower connecting plate. The inner diameter of the radial bearing segment tile is larger than the outer diameter of the main shaft, so that the bearing bracket is aligned with the main shaft axis.
It simplifies the installation process, saves manpower and material costs, avoids difficult operations in confined spaces, and ensures that the bearing bracket axis is aligned with the main axis, reducing readjustment time.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the tubular turbine generator field, concretely relates to a tubular turbine generator radial bearing block tile and bearing support common sleeve shaft structure. BACKGROUND
[0002] In the traditional tubular turbine generator unit bearing support and radial bearing block tile and shaft sleeve process, usually need first the main shaft installation and fix well, then again bearing support sleeve shaft and fix in the specified position, finally radial bearing block tile is installed in the corresponding position one by one.In this process, because the space between bearing support and main shaft is very narrow, radial bearing block tile can only be hoisted to the lower side of main shaft in advance, and then pushed to the predetermined position in the circumferential direction for installation.This installation mode process is complicated, and very time-consuming;And the weight of radial bearing tile is about several hundred kilograms, which makes the on-site installation extremely difficult, and an urgent need for a tubular turbine generator radial bearing block tile and bearing support common sleeve shaft structure to solve the above problems. SUMMARY
[0003] To solve the above problems, facilitate the tubular turbine generator unit bearing support and radial bearing block tile and shaft sleeve, the utility model discloses a tubular turbine generator radial bearing block tile and bearing support common sleeve shaft structure.
[0004] The technical scheme of the utility model: the tubular turbine generator radial bearing block tile and bearing support common sleeve shaft structure, comprising: bearing support, upper connecting plate, lower connecting plate, radial bearing block tile, main shaft;The radial bearing block tile is arranged in the radial direction of the bearing support, and the upper connecting plate and the lower connecting plate are arranged at the two ends of the radial bearing block tile respectively, the upper connecting plate is fixed on the bearing support by the upper connecting plate joint bolt, and the lower connecting plate is fixed on the bearing support by the lower connecting plate joint bolt.
[0005] Further, the inner diameter of the radial bearing block tile is greater than the outer diameter of the main shaft.
[0006] The application has the following beneficial effects:
[0007] 1. The radial bearing block tile in the utility model is fixed in the radial direction of the bearing support through the upper connecting plate and the lower connecting plate, can realize the radial bearing block tile and bearing support common sleeve shaft, avoid the high-difficulty operation that each radial bearing block tile is pushed to the predetermined position in the circumferential direction in the narrow space of the main shaft and the bearing support, and can save a lot of manpower and material resources cost.
[0008] 2. The inner diameter of the radial bearing block tile in the utility model is greater than the outer diameter of the main shaft, can guarantee that the bearing support is sleeved into the bearing support under the condition that the axis of the bearing support is consistent with the axis of the main shaft, and saves the time of re-adjusting the axis of the bearing support. BRIEF DESCRIPTION OF DRAWINGS
[0009] Figure 1 This is a schematic diagram of the structure of this utility model.
[0010] The following are the reference numerals in the diagram: 1. Bearing bracket; 2. Upper connecting plate; 3. Upper connecting plate clamping bolt; 4. Lower connecting plate; 5. Lower connecting plate clamping bolt; 6. Radial bearing segment; 7. Main shaft. Detailed Implementation
[0011] The present application will now be described in detail with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary, and the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the scope of the present application. Furthermore, descriptions of structures and technical common knowledge have been omitted in the following description to avoid unnecessarily obscuring the concepts of the present application.
[0012] Example 1: As Figure 1 As shown, a radial bearing segment tile and bearing bracket of a cross-flow turbine generator are mounted on a common shaft, including: bearing bracket 1, upper connecting plate 2, lower connecting plate 4, radial bearing segment tile 6, and main shaft 7; the radial bearing segment tile 6 is arranged in the inner diameter direction of the bearing bracket 1, and the upper connecting plate 2 and the lower connecting plate 4 are respectively arranged at both ends of the radial bearing segment tile 6. The upper connecting plate 2 fixes the connecting bolt 3 to the bearing bracket 1 through the upper connecting plate, and the lower connecting plate 4 fixes the connecting bolt 5 to the bearing bracket 1 through the lower connecting plate.
[0013] Furthermore, the inner diameter of the radial bearing segment 6 is larger than the outer diameter of the main shaft 7.
[0014] The purpose of this embodiment is that when the unit is installed on the construction site, in the installation room or pit, the radial bearing segment is first aligned with the inner diameter of the bearing bracket. At the same time, the inner diameter of the radial bearing segment is larger than the outer diameter of the shaft. This allows the radial bearing segment and the bearing bracket to be fitted together on the shaft when the axis of the bearing bracket is aligned with the axis of the main shaft. After fitting the shaft, it is not necessary to readjust the axis of the bearing bracket.
[0015] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
