Abstract
The utility model provides a disassembling tool for an external fan of a sealed generator, which consists of a bracket, a hexagon bolt, a small washer, a spring washer, a screw and a handle; the structure is characterized in that: the bracket is in a cuboid shape, a threaded hole is drilled in the middle of the bracket, 6 through holes are distributed along the axial direction of the threaded hole, and the 6 through holes are symmetrical according to the central line of the bracket; the hexagon head bolt, the small washer and the spring washer penetrate through the through hole on the bracket to be matched with the 2 threaded holes of the fan inner bushing, so that the fan and the disassembling tool are tightly assembled and fixed together; the handle passes through the through hole at the head part of the screw rod; the rod body of the screw rod is of an external thread structure, penetrates through a central threaded hole of the support and abuts against the end face of the rotating shaft of the generator, and the handle is rotated under the action of a thread pair through the screw rod and the central threaded hole of the support, so that the support and the rotating shaft move to drive the fan to move together, and the purpose of separating the fan from the generator is achieved.
Description
Technical field
The utility model is related to a kind of extracting tools, and when being overhauled for closed generator, external fan uses when dismantling.
Background technology
When degree of protection reaches the closed generator work of IP54, a large amount of heat can be generated inside closed generator.
In order to accelerate flow of external air speed, the heat dissipation capacity of unit interval is improved, reference, the design experiences for using for reference previous generator,
Generally all one external fan can be installed in the tail portion of closed generator.The inner liner of fan is matched with alternator shaft for interference
It closes, ensures not move during fan work.Consider that generator needs periodic inspection, and when overhauling, it is necessary to by external fan,
The parts such as rear end cap are dismantled, and external fan is depended merely on operative employee's hand disassembly with shaft interference fit and can not be realized.
For this purpose, considering the actual conditions of production scene, need to design a versatile closed generator external fan
Repair demolition tooling.
Invention content
In order to easily dismantle the external fan in closed generator, it is external that the utility model provides a kind of sealed electric generator
The extracting tool of fan.
The utility model is achieved like this：
A kind of extracting tool of sealed electric generator external fan, including stent, hexagon-headed bolt, small washer, spring washer,
Screw rod and handle；It is characterized in that：Contoured cradle is cuboid, and centre drill is there are one threaded hole, along screw thread axially bored line or so
Direction is distributed 6 through-holes in total, and 6 through-holes are symmetrical by carriage center line；The end of the screw rod is opened there are one through-hole, and shaft is
External thread structure；The handle is round rod iron.
Preferably, the extracting tool contains 2 groups of hexagon-headed bolts, small washer, spring washers.
Preferably, the material that the extracting tool uses is cold-rolled steel Q235 material.
In use, hexagon-headed bolt passes through the threaded hole of through-hole and sealed electric generator external fan on stent closely to connect
It connects, screw rod passes through the threaded hole on stent, and handle resists the end face of sealed electric generator shaft, Ran Houzhuan across the through-hole on screw rod
Fixed handle makes screw rod that the relative movement of position occur under the action of screw thread pair with stent, thus by the external wind of sealed electric generator
Fan removes.
The utility model achievees the purpose that dismantle closed generator external fan using the design feature of tool in itself, leads to
With property is good, processing and manufacturing is simple, performance is stable, easy to operate, it is particularly suitable for motor common currently on the market.
The beneficial effects of the utility model are：(1) disassembling fixture processing is simple, convenient to install and maintain, versatile；(2)
Structural behaviour is stable, reliable；(3) it is easy to operate, it is highly practical, it is of low cost.

Fig. 5 is the assembling schematic diagram of the utility model and the external fan in closed generator.
In the figure 1, stent, 101, threaded hole, 102, the through-hole on stent, 2, hexagon-headed bolt, 3, screw rod, 301, spiral shell
Through-hole on bar, 4, handle, 5, the external fan in closed generator.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figures 1-4, the utility model is such to what is implemented, a kind of dismounting work of sealed electric generator external fan
Tool, including stent 1, hexagon-headed bolt 2, screw rod 3, handle 4, small washer and spring washer.1 shape of stent be cuboid, center
Threaded hole 101 there are one boring, is distributed six through-holes 102, six through-holes 102 are pressed in total along 101 axis left and right directions of threaded hole
1 center line of stent is symmetrical；The end of the screw rod 3 is opened there are one through-hole 301, and shaft is external thread structure；The handle 4 is circle
Shape rod iron.
Six through-holes 102 on stent 1 form 3 groups, can be used for the sealed electric generator external fan of 3 kinds of specifications.It uses
When, first stent 1 is kept steady, measures the pitch-row of fan upper screwed hole, is determined using any group through-hole 102 on stent 1；Take out two groups
They are each passed through corresponding through-hole 102 on stent 1 by hexagon-headed bolt 2, small washer, spring washer, then with the spiral shell on fan
Pit alignment rotates to bottom, it is impossible to have gap, it is necessary to assure stent 1 is fixed together with fan；Screw rod 3 is taken out, across stent
1 screwed hole of centre 101, until the end face of alternator shaft is withstood in tail portion；Handle 4 is taken out, across the through-hole of 3 end of screw rod
301, operative employee holds 4 both sides of handle respectively, firmly rotates clockwise, screw rod 3 is made to occur under the action of screw thread pair with stent 1
The relative movement of position makes stent 1 be moved towards away from the direction of generator, and fan is driven to move together.
If during handle 4 is rotated, when encountering bigger resistance, then rotate for several weeks counterclockwise, then rotate clockwise；
It below if when also meeting obstructions larger, rotates for several weeks, then rotates clockwise counterclockwise；And so on several times, until outer
It puts fan to come off from alternator shaft, then sets about preparing other tools, dismantle other parts of generator.
