Abstract
The utility model relates to a structure for mounting a cooling fan of a high-voltage generator. The structure comprises a rotating shaft, a rotor member is installed at the central section of the rotating shaft, and a shaft coupling is thermally sleeved on an output terminal of the rotating shaft. The structure is characterized in that an excircle of an inner side terminal of the shaft coupling is provided with a shaft shoulder, the shaft coupling is sleeved with a fan seat, the fan seat is fixedly connected to the shaft shoulder of the excircle of the shaft coupling via a plurality of axial bolts, and a fan is fixedly connected with the fan seat via bolts. A structure that the shaft shoulder is disposed on the excircle of the shaft coupling, and the fan seat is sleeved on the shaft coupling with interval and connected with the shaft shoulder is used. The structure is simple and compact, mounting and dismounting are convenient and efficient, production efficiency is improved, and labor cost is reduced; and the structure facilitates replacing the fan seat and maintaining the generator.
Description
Technical field
The utility model relates to a kind of generator, especially relates to a kind of mounting structure of high-voltage generator cooling fan.
Background technology
Cooling fan is the important component of high-voltage generator, and it designs and produces the direct temperature rise size that affects high-voltage generator work operation.Loss is the main cause that causes temperature rise to raise, and high-voltage generator produces in the course of the work loss and comprises (having iron loss, frictional dissipation, copper loss, assorted damage), produces heat, and these heats pass to ironcore choke, make winding temperature temperature rise unshakable in one's determination.And the air force of cooling fan has determined winding temperature rise size, cooling, even may cause generator to burn out bad in the situation that.As shown in Figure 3, the rotating shaft 8 of existing high-voltage generator ' output hot jacket have shaft coupling 7 ' and fan base 4 ', shaft coupling 7 ' and fan base 4 ' by the same shaft shoulder 5 ' location, fan 3 ' be bolted to connection fan base 4 ', rotor assembly 1 ' hot jacket rotating shaft 8 ' middle part, therefore install rotor assembly 1 ' before, fan base 4 ' need to from rotating shaft 8 ' the other end pack in advance, in assembling process, mounting distance is long, give fan base 4 ' assembling bring inconvenience, difficulty is installed, and installation effectiveness is low, and cost of labor is high.And existing fan base adopts hot jacket mode to assemble, when needs are changed, this structure can not be changed easily, to maintenance, causes difficulty.
Utility model content
The applicant, for above-mentioned problem, is studied improvement, and a kind of mounting structure of high-voltage generator cooling fan is provided, simple and compact for structure, mount and dismount convenient and swiftly, enhance productivity, reduce cost of labor, meanwhile, facilitate the replacing of fan base, provide convenience to the maintenance of generator.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of mounting structure of high-voltage generator cooling fan, comprise rotating shaft, rotor assembly is arranged on the middle part of described rotating shaft, shaft coupling hot jacket is at the output of described rotating shaft, the cylindrical of described shaft coupling medial extremity is provided with the shaft shoulder, fan base is sleeved on described shaft coupling, and described fan base is fixedly connected with the shaft shoulder on the cylindrical of described shaft coupling by several axial bolts, and fan is bolted to connection described fan base.
Further:
Described rotor assembly hot jacket, in described rotating shaft, is provided with flat key between described rotor assembly and described rotating shaft.
Between described fan base and described shaft coupling, it is matched in clearance.
Technique effect of the present utility model is:
The mounting structure of the disclosed a kind of high-voltage generator cooling fan of the utility model, adopt on shaft coupling cylindrical the shaft shoulder is set, fan base gap is sleeved on shaft coupling and connects the structure of the shaft shoulder, simple and compact for structure, mount and dismount convenient and swiftly, enhance productivity, reduce cost of labor, meanwhile, facilitate the replacing of fan base, provide convenience to the maintenance of generator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the mounting structure schematic diagram of prior art fan seat.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As Fig. 1, shown in 2, the utility model comprises rotating shaft 8, rotor assembly 1 hot jacket is arranged on the middle part of rotating shaft 8, between rotor assembly 1 and rotating shaft 8, be provided with flat key 2, shaft coupling 7 hot jackets are at the output of rotating shaft 8, the cylindrical of shaft coupling 7 medial extremitys is provided with the shaft shoulder 5, on the shaft shoulder 5, offer screwed hole, fan base 4 is sleeved on shaft coupling 7, between fan base 4 and shaft coupling 7, it is matched in clearance, can facilitate the installation and removal of fan base 4 like this, fan base 4 is fixedly connected with the shaft shoulder 5 on the cylindrical of shaft coupling 7 by 12 axial bolts 6, fan 3 is bolted to connection fan base 4, make fan 3, fan base 4 and shaft coupling 7 are connected in one.
When the utility model is installed, first by the rotating shaft of high-voltage generator 8 together with shaft coupling 7 hot jackets, rotor assembly 1 hot jacket is fitted in rotating shaft 8, from right side by fan base 4, be sleeved on shaft coupling 7 again, and by bolted, then fan 3 is contained on fan base 4, and use bolted.In the utility model, fan base 4 is installed to the structure of shaft coupling 7, installation and removal fan base 4 is all very convenient, change and attended operation simple and fast, for client changes fan, providing convenience, effectively improve operating efficiency, is a kind of mounting structure of cooling fan of efficient quick.
When needs are safeguarded or are changed fan base 4, do not need to pull down rotor assembly 1, only need to unclamp bolt 6, can change quickly and easily, the operating time shortens greatly, and operating efficiency effectively improves.
