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
The present invention relates to a kind of method of attachment of rotor field spider, particularly a kind of method of attachment of rotor support power generator.
Background technology
The important feature component of current known generators is generally made up of stator, rotor (comprising magnetic pole, yoke), rotor field spider etc.In, the rotor field spider of large-scale capacity hydraulic generator, be connect yoke and rotating shaft all-in-one-piece intermediate member, when normally running, rotor field spider will bear gravitational moment, the effect such as centrifugal force of self of moment of torsion, magnetic pole and yoke, therefore, rotor field spider is the vitals of stressed complexity.
Along with the increase of generator capacity, the corresponding increase of overall dimension of generator, the mechanical property requirements for rotor field spider also improves accordingly.By traditional at present structural union, rotor field spider structure is generally welded to form by small gusset, large gusset and center ring flat-plate, needs the position of carrying out welding too much respectively, the raw material used are also a lot, add processing technology complexity, welding difficulty is large and quality is difficult to guarantee, and cost increases.
Summary of the invention
The present invention solves the technical problem existed in known technology, provides the method for attachment of a kind of manufacturing process, the simple rotor support power generator of welding sequence.
To achieve these goals, the present invention realizes by following technical scheme:
A kind of method of attachment of rotor support power generator, it is characterized in that: rotor field spider comprises annular plate, center ring flat-plate, the large each parts of gusset, described annular plate is rolled by a block plate blanking and forms, with described center ring flat-plate through being welded to form one, form centerbody blank, weld with described large gusset after processing is carried out to center chaeta blank.
Further, the welding position that the centerbody blank after processing welds with described large gusset is equipped with 2.
The invention has the beneficial effects as follows: materials'use is few, waste material is few, and manufacturing process is few, and technique is simple, convenient operation, weld seam is beneficial to inspection, easily ensures weldquality, improves weld strength, manufacturing cycle is short, and do not need special technological equipment, therefore cost is low, cheap.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is the cut-away view that original rotor field spider connects.
Fig. 2 is the schematic diagram that original rotor field spider connects.
Wherein Reference numeral is expressed as: 11-tradition small gusset, the large gusset of 12--tradition, 13-conventional center ring flat-plate, 14,15,16,17,18-traditional welding point.
Fig. 3 is the cut-away view that rotor field spider of the present invention connects.
Fig. 4 is the schematic diagram that rotor field spider of the present invention connects.
Wherein Reference numeral is expressed as: 1-rotor field spider, 2-annular plate, 3-center ring flat-plate, the large gusset of 4-, 5-centerbody blank, and 6,7-pad.
Embodiment
Below in conjunction with drawings and Examples, further illustrate the present invention.
As shown in Figure 1, rotor field spider structure traditional at present comprises traditional small gusset 11, the large gusset 12 of tradition, the each parts of conventional center ring flat-plate 13, need respectively to weld five traditional welding points 14,15,16,17,18 in Fig. 1, this just causes the raw material of use many, and processing technology is complicated, welding difficulty is large and quality is difficult to guarantee, and cost increases.
As shown in Figure 2, the rotor field spider 1 of new method welding is adopted to comprise annular plate 2, center ring flat-plate 3, the each parts of large gusset 4, annular plate 2 is rolled by a block plate blanking and forms, with center ring flat-plate 3 through being welded to form one, form centerbody blank 5, weld with large gusset 4 after processing is carried out to center chaeta blank 5, the method welding is adopted only to need butt welding contact 6, 7 weld, weld seam quantity is few, adopt new rotor field spider welding method, materials'use is few, waste material is few, manufacturing process is few, technique is simple, convenient operation, weld seam is beneficial to inspection, easy guarantee weldquality, improve weld strength, manufacturing cycle is short, do not need special technological equipment, therefore cost is low, cheap.
