Abstract
The utility model relates to the field of dismantling and maintaining a generator, in particular to a removing tool of a generator thrust head, which comprises a force exertion plate, wherein at least one fastening piece is arranged at the middle part of the force exertion plate, a top thread and a draw thread which vertically penetrate through a plate surface are arranged on the surface of the force exertion plate, the fastening piece, the top thread and the draw thread penetrate through the surface of the force exertion plate from the same direction, the length of each fastening piece which extends out of the surface of the force exertion plate is smaller than that of the top thread which extends out of the surface of the force exertion plate, the length of the top thread extending out of the surface of the force exertion plate is smaller than that of the draw thread extending out of the surface of the force exertion plate, and the distances from the axes of the top thread and the draw thread to each fastening piece are all smaller than the distance from the side wall of the thrust head to the main axis of the generator. The removing tool has a simple structural principle, strong practicability and a low cost, and is suitable for being popularized and applied, and the thrust head is dismantled more conveniently.
Description
Technical field
The utility model relates to generator demolition and maintenance field, specifically, relates to a kind of generator thrust collar extracting tool.
Background technology
The generator thrust collar exists the inconvenient problem of dismounting in the maintenance dismounting.When decomposing the thrust collar of thrust bearing, usually adopt traditional handicraft to pull up thrust collar by force, very easily damage cooperates seam, along with increasing of unit maintenance number of times, certainly will destroy the tolerance fit between thrust collar and the main shaft, make it to become gradually matched in clearance, this safe operation to unit is totally unfavorable.
The utility model content
The purpose of this utility model is to provide a kind of generator thrust collar extracting tool.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of generator thrust collar extracting tool, comprise application of force dish, the middle part of described application of force dish has at least one securing member, application of force panel surface is provided with the jackscrew and the wire drawing of vertically passing card, described securing member, jackscrew, wire drawing is all from passing the surface of application of force dish in the same way, the length that described securing member stretches out application of force panel surface is stretched out the length of application of force panel surface less than jackscrew, the length that described jackscrew stretches out application of force panel surface is stretched out the length of application of force panel surface less than described wire drawing, the axis of described jackscrew and wire drawing to the distance of fastener axis all less than the distance of thrust collar sidewall to generator shaft.
Described application of force dish is rigid disc or oval plate or rectangular disk.
Described securing member is two, and described jackscrew and wire drawing all are positioned at the outside of two securing members and about the axis symmetry of two securing members.
The beneficial effects of the utility model are:
1, structural principle is simple, and is practical;
2, with low cost, be fit to apply;
3, adopt welded-steel plate construction, use securing member to be fixed in the rotating shaft, the thrust collar dismounting is convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an operation principle schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Embodiment: referring to Fig. 1, Fig. 2.
A kind of generator thrust collar extracting tool, comprise application of force dish 1, the middle part of described application of force dish 1 has at least one securing member 2, application of force dish 1 surface is provided with the jackscrew 3 and the wire drawing 4 of vertically passing card, described securing member 2, jackscrew 3, wire drawing 4 is all from passing the surface of application of force dish 1 in the same way, the length that described securing member 2 stretches out application of force dish 1 surface is stretched out the length on application of force dish 1 surface less than jackscrew 3, the length that described jackscrew 3 stretches out application of force dish 1 surface is stretched out the length on application of force dish 1 surface less than described wire drawing 4, the axis of described jackscrew 3 and wire drawing 4 to the distance of securing member 2 axis all less than the distance of thrust collar 5 sidewalls to generator shaft 6.
The securing member 2 of present embodiment is a bolt, also can be other known parts such as screw.
Described application of force dish 1 is rigid disc or oval plate or rectangular disk.
The preferred disk that adopts is as application of force dish, guarantees that easily the application of force is with stressed even.
Described securing member 2 is two, and described jackscrew 3 and wire drawing 4 all are positioned at the outside of two securing members 2 and about the axis symmetry of two securing members 2.Equally, this design also can guarantee the application of force and stressed evenly.
As shown in Figure 2, when adopting instrument of the present utility model that thrust collar is dismantled, with securing member 2 application of force dish 1 is fixed on the generator shaft 6, wire drawing 4 is fixed with thrust collar, jackscrew 3 holds out against thrust collar 5, and slowly precession, and the pressure of 3 pairs of thrust collars 5 of jackscrew is converted into the pulling force of wire drawing 4, slowly thrust collar 5 is separated with generator shaft 6, smoothly thrust collar 5 is pulled down.
