Description
Technical field
The utility model belongs to generator amature technical field, particularly relates to a kind of Retaining Ring on Generator Rotor mounting structure.
Background technology
Conventional air inner-cooled generator rotor end bell adopts retaining ring ring key to carry out the fixing of retaining ring mostly, and retaining ring and the fixing of centering ring are also rely on centering ring ring key to be fixed.There is following shortcoming in this kind of structure retaining ring mounting structure: 1, retaining ring ring key and centering ring ring key width little, but require that machining accuracy is high, manufacture difficulty large, cost is high; 2. retaining ring and rotor body cooperation place are owing to there being ring key, and therefore this place's intensity is slackened by ring key installing hole, reduces the coefficient of safety at this place.
Utility model content
The utility model is in order to solve the problems of the prior art, and providing a kind of does not need ring key, Retaining Ring on Generator Rotor mounting structure reliable, easy for installation.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of Retaining Ring on Generator Rotor mounting structure, it comprises rotor body and is set in the retaining ring on rotor body, the inner circle front portion of described retaining ring is provided with retaining ring boss, the inner circle rear portion of retaining ring offers retaining ring groove, position corresponding to described retaining ring boss on described rotor body offers rotor recesses, described rotor recesses matches with described retaining ring boss, described retaining ring groove is provided with the centering ring for fixed rotor coil, described centering ring is set on rotor body, described centering ring and retaining ring groove corresponding position start there is centering ring boss, described centering ring boss and described retaining ring fit depressions.
Described centering ring offers the compensating groove for installing rotor balance.
The beneficial effects of the utility model are: eliminate ring key in the utility model, decrease material cost and the processing cost of ring key, manufacture difficulty, cycle reduction, have higher economic benefit and technique superiority; Rotor recesses matches with retaining ring boss, centering ring boss and retaining ring fit depressions, assembly difficulty reduces between retaining ring and centering ring and between retaining ring and rotor body, eliminate ring key, adopt that rotor recesses matches with retaining ring boss, centering ring boss and retaining ring fit depressions, retaining ring and rotor body cooperation place retaining ring are without slackening, and this place's retaining ring coefficient of safety increases; Centering ring offering the compensating groove for installing rotor balance, being convenient to adjust by installing the balance of rotor balance to rotor.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model;
Fig. 2 is the enlarged drawing at A place in Fig. 1;
Fig. 3 is the enlarged drawing at B place in Fig. 1.
Embodiment
As shown in Figure 1 to Figure 3, a kind of Retaining Ring on Generator Rotor mounting structure of the present utility model, the retaining ring 1 that it comprises rotor body 2 and is set on rotor body 2, the inner circle front portion of retaining ring 1 is provided with retaining ring boss 5, the inner circle rear portion of retaining ring 1 offers retaining ring groove 7, on described rotor body 2, the position corresponding to retaining ring boss 5 offers rotor recesses 6, described rotor recesses 6 matches with described retaining ring boss 5, described retaining ring groove 7 place is provided with the centering ring 3 for fixed rotor coil, described centering ring 3 is set on rotor body 2, described centering ring 3 starts there is centering ring boss 8 with retaining ring groove 7 corresponding position, described centering ring boss 8 matches with described retaining ring groove 7.Centering ring 3 also offering the compensating groove 4 for installing rotor balance, being convenient to adjust by installing the balance of rotor balance to rotor.
When the utility model is installed, the retaining ring groove 7 of retaining ring 1 is first cooperated together by hot jacket with the centering ring boss 8 of centering ring 3, and then the retaining ring boss 5 of retaining ring 1 is cooperated together by hot jacket with the rotor recesses 6 of rotor body 2, the installation of retaining ring 1 entirety and rotor body 2 can be completed.This mounting structure eliminates ring key, decreases material cost and the processing cost of ring key, manufactures difficulty, cycle reduction, has higher economic benefit and technique superiority; Rotor recesses 6 coordinates with retaining ring boss 5 hot jacket, centering ring boss 8 coordinates with retaining ring groove 7 hot jacket, to make between retaining ring 1 and centering ring 3 and between retaining ring 1 and rotor body 2, assembly difficulty reduces, and retaining ring 1 with rotor body 2 cooperation place retaining ring without slackening, this place's retaining ring coefficient of safety increases.
Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although be described in detail the utility model with reference to above-described embodiment, those of ordinary skill in the art is to be understood that: still can modify to the utility model or equivalent replacement, and not departing from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of right of the present utility model.
