Abstract
The utility model discloses a sectional type hoisting screw structure of a stator of a semi-direct-drive permanent magnet wind driven generator, which is formed by connecting a first screw section and a second screw section through screw threads, wherein one end of the first screw section is a threaded connection end with external screw threads, and an invaginated groove position is formed on the first screw section, so that the first screw section is formed with a reducing section with two large ends and a small middle part, the reducing section is close to the threaded connection end of the first screw section, one end of the second screw section is processed with an internal screw hole for connecting with the threaded connection end, thereby connecting the first screw section and the second screw section to form a whole hoisting screw, and the reducing section of the first screw section can ensure that the whole hoisting screw avoids the interference with the coil of the stator of the generator, thereby avoiding the damage of the external insulation of the coil, thereby ensuring the product quality, having practical application value and being worth popularizing.
Description
Technical Field
The utility model relates to a half technical field who directly drives permanent magnet wind power generator especially indicates a half permanent magnet wind power generator stator sectional type hoist and mount screw rod structure that directly drives.
Background
In industry known, aerogenerator stator comprises stator core, condenser tube, coil and conducting ring, and in the production process, the stator need be transported between each process, adopts the screw rod to carry out the handling usually, and the screw rod then is installed between condenser tube and coil, because the nonconformity of production, leads to the screw rod installation back easily, interferes with the coil, consequently, when transporting, can take place the impaired condition of the outside insulation of coil.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome prior art's shortcoming and not enough, provide a half permanent magnet wind power generator stator sectional type hoist and mount screw rod structure that directly drives, can avoid taking place the impaired condition of coil outside insulation.
In order to achieve the above object, the present invention provides a technical solution: the utility model provides a half directly drives permanent magnet wind power generator stator sectional type hoist and mount screw rod structure, is formed through threaded connection by first screw rod section and second screw rod section, wherein, the one end of first screw rod section is for the thread connection end that has the external screw thread to be formed with the recess position of caving in on this first screw rod section, and then make this first screw rod section be formed with the little reducing section in the middle of one section two big, just the reducing section is close to the thread connection end in first screw rod section, the one end processing of second screw rod section has an internal thread hole for be connected with above-mentioned thread connection end, thereby couple together first screw rod section and second screw rod section, constitute a whole hoist and mount screw rod, and pass through the reducing section of first screw rod section can make whole hoist and mount screw rod and generator stator's coil emergence interference.
Compared with the prior art, the utility model, have following advantage and beneficial effect:
through the utility model discloses special design's sectional type hoist and mount screw rod structure can avoid coil external insulation's damage effectively, and then ensures product quality, has practical application and worth promoting.

Fig. 1 is the utility model discloses a sectional type hoist and mount screw rod structure is at the installation sketch map on aerogenerator stator.
Fig. 2 is a cross-sectional view of fig. 1 (from a, it is clear that the groove positions avoid the coils of the stator).
Figure 3 is the utility model discloses a sectional type hoist and mount screw rod structure's assembly drawing.
FIG. 4 is a schematic view of the structure of the first screw section.
FIG. 5 is a cross-sectional view of the second screw section.
Detailed Description
The present invention will be further described with reference to the following specific embodiments.
Referring to fig. 1 to 5, the sectional type hoisting screw structure of the stator of the direct-drive permanent magnet wind turbine generator provided by this embodiment is formed by connecting a first screw section 1 and a second screw section 2 by screw threads, wherein one end of the first screw section 1 is a threaded connection end 11 with external threads, and a recessed groove is formed on the first screw section 1, so that the first screw section 1 is formed with a diameter-changing section 12 with two large ends and a small middle part, the diameter-changing section 12 is close to the threaded connection end 11 of the first screw section 1, one end of the second screw section 2 is processed with an internal threaded hole 21 for connecting with the threaded connection end 11, so as to connect the first screw section 1 and the second screw section 2 together to form a whole hoisting screw, and the whole hoisting screw can avoid interference between the whole hoisting screw and a coil 31 of the generator stator 3 through the diameter-changing section 12 of the first screw section 1, further avoid the damage of coil 31 external insulation to ensure product quality, have practical application value, be worth promoting.
The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that all the changes made according to the shape and principle of the present invention should be covered within the protection scope of the present invention.
Claims (1)
1.
