Abstract
The utility model relates to a stator core lamination-pressing device of a hydroturbine. The device is characterized in that: layers of stator core laminations are assembled in the bed of the hydroturbine; tooth pressure core strips are assembled on the upper and the lower ends of the stator core laminations; an upper annular groove and a lower annular stage are respectively arranged on the bed; the lower annular stage is welded with a full coiled tooth support provided with a supporting rib plate; an adjusting bolt and an adjusting nut are assembled on a small partitioned tooth plate; a pressing fixture block is assembled in the annular groove behind the small partitioned tooth plate; lug bosses are respectively arranged on the ends of the full coiled tooth support and the small partitioned tooth plate; and matching sockets are correspondingly arranged on the upper and the lower tooth pressure core strips. Consequently, when tightly fixing the stator core laminations, the device does not need a penetrating screw rod and insulating parts thereof, as a result, the structure is greatly simplified, and the cost is reduced. Moreover, the device also has the advantages of simple structure, easy fabrication and installation and safe and reliable operation.
Description
Technical field
The utility model relates to a kind of hydraulic turbine stator core stamping sheet mounting technique, especially a kind of hydraulic turbine stator core stamping sheet hold down gag.
Background technology
Known stator mounting structure vertical or horizontal hydrogenerator is: stator core stamping sheet from level to level is installed in support, at the stator core stamping sheet upper and lower side iron core teeth press strip is installed, in the iron core teeth press strip outside by tooth support and stretching screw compress core stamping up and down.Core stamping " core through screw rod " structure is passed in this employing, need prevent that also the screw rod that passes stator core yoke portion from contacting with stator punching, cause the punching scaling loss, so core through screw rod must be wrapped up insulation at the iron core position; In order to prevent that place sensed in " core through screw rod " from producing electric current, also must come the nut and the insulation of upper and lower tooth support that are screwed on the screw rod; In order to prevent the core through screw rod vibration, pass iron core portion at core through screw rod and also will install the insulation flexure strip additional.This shows that the compressing structure of bulb through-flow type hydraulic turbogenerator stator iron core employing " core through screw rod " is very complicated, loaded down with trivial details, the installation difficulty, and the cost height.
Summary of the invention
The utility model provides a kind of simple in structure, easy-to-install hydraulic turbine stator core stamping sheet hold down gag for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of hydraulic turbine stator core stamping sheet hold down gag, comprise support, be installed in the stator core stamping sheet from level to level in the support, be installed in the iron core teeth press strip of stator core stamping sheet upper and lower side, and the hold down gag of upper and lower side iron core teeth press strip is formed, described hold down gag is to be shaped on cannelure and following annular table on the support respectively, be welded on the following annular table and have the whole circle tooth support of bearing rib, the little tooth support of piecemeal that has bearing rib is installed in the last cannelure, be equipped with on the little tooth support of piecemeal and adjust bolt and adjust nut, be equipped with in the cannelure of the little tooth support of piecemeal rear end and compress fixture block.
The utility model can also adopt following technical scheme:
The end of described whole circle tooth support and the little tooth support of piecemeal is shaped on boss respectively, up and down the corresponding groove that is shaped on coupling on the iron core teeth press strip.
Advantage and the good effect that the utlity model has are:
Owing to be shaped on cannelure and following annular table on the support, at the whole circle tooth support that descends the cored punching that is welded on the annular table, in last cannelure, compress the little tooth support of piecemeal and the fixture block of core stamping, therefore need not core through screw rod and insulating part thereof, simplify the structure greatly, reduced cost; In addition the utility model also have simple in structure, be easy to make and installation, advantage safe and reliable to operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, support; 2, following annular table; 3, bearing rib; 4, whole circle tooth support; 5, groove; 6, boss; 7, stator core stamping sheet; 8, boss; 9, groove; 10, iron core teeth press strip; 11, the little tooth support of piecemeal; 12, adjust nut; 13, adjust bolt; 14, bearing rib; 15, fixture block; 16, go up cannelure.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, stator core stamping sheet 7 from level to level is installed in the support 1 of the hydraulic turbine, iron core teeth press strip 10 is installed at the stator core stamping sheet upper and lower side.The hold down gag of stator core stamping sheet is to be shaped on cannelure 16 and following annular table 2 on the support respectively, be welded on the following annular table and have the whole circle tooth support 4 of bearing rib 3, the little tooth support 11 of piecemeal that has bearing rib 14 is installed in the last cannelure, be equipped with on the little tooth support of piecemeal and adjust bolt 13 and adjust nut 12, be equipped with in the cannelure of the little tooth support of piecemeal rear end and compress fixture block 15.End at whole circle tooth support and the little tooth support of piecemeal is shaped on boss 6,8 respectively, and the corresponding groove 5,9 that is shaped on coupling on the iron core teeth press strip up and down so more helps the fastening location of closing of stator core stamping sheet.Therefore this structure need not core through screw rod and insulating part thereof, simplifies the structure greatly, has reduced cost; In addition the utility model also have simple in structure, be easy to make and installation, advantage safe and reliable to operation.
