Problems solved by technology

According to the current traditional structural connection method, the rotor support structure is generally composed of small ribs, large ribs and the central ring plate. There are too many welding positions and a lot of raw materials used. In addition, the processing technology is complicated and the welding is difficult. Large and difficult to guarantee quality, cost increase

Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment, further illustrate the present invention.

[0017] Such as figure 1 As shown, the current traditional rotor support structure includes the traditional small rib plate 11, the traditional large rib plate 12, and the traditional center ring plate 13. figure 1 Five traditional welding points 14, 15, 16, 17, 18 are welded, which causes many raw materials to be used, complicated processing technology, difficult welding and difficult quality assurance, and increased cost.

[0018] Such as figure 2 As shown, the rotor bracket 1 welded by the new method includes the ring plate 2, the center ring plate 3, and the large rib plate 4. The ring plate 2 is rolled from a steel plate and welded with the center ring plate 3. One body to form the center body blank 5, and weld the center body blank 5 with the large rib plate 4 after processing. This method only needs to weld the welding points 6 and 7, and the number of wel...

Abstract

The invention relates to a connecting method of a hydro generator rotor support. The rotor support comprises an annular plate, a center annular plate and a large rib plate, wherein the annular plate is formed by coiling a steel plate by blanking and is integrated with the center annular plate by welding so as to form a center blank piece, the center blank piece is machined and then is welded to the large rib plate, and two welding positions of the machined center blank piece and the large rib plate are available. By adopting the connecting method, material consumption is small, material waste is small, making procedures are less, the process is simple, the operation is convenient, welding seams are convenient to check, the quality of the welding seams is easy to ensure, the strength of the welding seams is improved, the making period is short, and special process equipment is not needed, and thus the cost is low and the making price is low.

Description

technical field [0001] The invention relates to a connection method of a rotor support, in particular to a connection method of a hydroelectric generator rotor support. Background technique [0002] Currently known important structural components of a generator are generally composed of a stator, a rotor (including magnetic poles, a yoke), a rotor bracket, and the like. The rotor support of medium and large capacity hydro-generators is an intermediate part that connects the yoke and the shaft as a whole. During normal operation, the rotor support must bear the effects of torque, the gravity moment of the magnetic poles and the yoke, and its own centrifugal force. Therefore, The rotor bracket is an important component with complex forces. [0003] As the capacity of the generator increases, the external dimensions of the generator increase accordingly, and the requirements for the mechanical performance of the rotor bracket also increase accordingly. According to the curren...
