Abstract
The utility model discloses a new removing tool which comprises a force applied disc, the middle of the force applied disc is provided with at least a fastener, the surface of the force applied disc is provided with a top wire and a drawing wire which vertically pass through the surface of the force applied disc, the fastener, the top wire and the drawing wire all pass through the surface of the force applied disc from the same direction, the length of a part of the fastener protruding from the surface of the force applied disc is less than the length of a part of the top wire protruding from the surface of the force applied disc, the length of the part of the top wire protruding from the surface of the force applied disc is less than the length of a part of the drawing wire protruding from the surface of the force applied disc, and the distance between the axial line of the top wire and the axial line of the fastener and the distance between the axial line of the drawing wire and the axial line of the fastener are both less than the distance between the side wall of a thrust head and a main shaft of a power generator. The new removing tool disclosed by the utility model is simple in structure theory, strong in practical applicability, low in cost, and suitable for promotion and application, so that the thrust head is removed more conveniently.
Description
Technical field
The utility model relates to a kind of generator and safeguards extracting tool, particularly a kind of novel 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 the utility model is to provide a kind of novel extracting tool.
The technical scheme that the utility model adopts is: a kind of novel extracting tool; Comprise application of force dish, the middle part of said application of force dish has at least one securing member, and application of force panel surface is provided with the jackscrew and the wire drawing of vertically passing card; Said securing member, jackscrew, wire drawing are all from passing the surface of application of force dish in the same way; The length that said securing member stretches out application of force panel surface is stretched out the length of application of force panel surface less than jackscrew, and the length that said jackscrew stretches out application of force panel surface is stretched out the length of application of force panel surface less than said wire drawing, the axis of said jackscrew and wire drawing to the distance of fastener axis all less than the distance of thrust collar sidewall to generator shaft.
Said application of force dish is rigid disc or oval plate or rectangular disk.
Said securing member is two, and said jackscrew and wire drawing all are positioned at the outside of two securing members and about the axis of two securing members symmetry.
The beneficial effect of the utility model is:
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 the structural representation of the utility model.
Fig. 2 is the operation principle sketch map of the utility model.
The specific embodiment
Embodiment such as Fig. 1; Shown in Figure 2, a kind of novel extracting tool comprises application of force dish 1; The middle part of said 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 wire drawing 4 that vertically passes card, and said securing member 2, jackscrew 3, wire drawing 4 be all from passing the surface of application of force dish 1 in the same way, and the length that said 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 said jackscrew 3 stretches out application of force dish 1 surface is stretched out the length on application of force dish 1 surface less than said wire drawing 4, the axis of said 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.
Said 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.
Said securing member 2 is two, and said 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.
When the instrument of employing the utility model is dismantled thrust collar; With securing member 2 application of force dish 1 is fixed on the generator shaft 6, wire drawing 4 is fixed with thrust collar, and jackscrew 3 holds out against thrust collar 5; And slowly precession; 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.
