Description
Technical field
The utility model relates to field of mechanical technique, about a kind of rotor on motor, especially about a kind of rotor of hydraulic generator.
Background technology
Rotor is the rotating parts in motor.Motor is made up of rotor and stator two parts, and it is used to the conversion equipment realizing electric energy and mechanical energy and mechanical energy and electric energy.Wherein, the yoke in rotor is indispensable part, and due to the existence of yoke, we can pass to the magnetic line of force of live wire bag (coil), magnet generation the place of our needs, and this point has a bit as the wire in circuit.It is often referred to itself not production magnetic field (magnetic line of force), the soft magnetic material of a magnetize line of force transmission in magnetic circuit, yoke generally adopt the soft iron that permeability is higher.Although the basic structure of existing yoke has been applied in motor widely, in hydraulic generator structure, obviously require different.Such as, the overall volume of hydraulic generator is very large, and the volume of whole yoke is also just suitable large, no matter is transport or installs or dismounting, is all quite loaded down with trivial details, too increases corresponding cost simultaneously concerning whole process.In addition, the heat that the yoke of large volume operationally produces is very high, and the yoke of existing structure does not possess good heat sinking function substantially, and the time has been grown and affected work.
Utility model content
The purpose of this utility model is for the problems referred to above, provides the rotor of a kind of transport rational in infrastructure, simple, convenient, good heat dissipation effect.
For achieving the above object, the utility model have employed following technical proposal: a kind of rotor of hydraulic generator, comprise the yoke of the sheet of in layer closed assembly, the assembly that magnetic pole is connected with yoke, it is characterized in that, described pole lamination lower end is provided with dovetail and connects projection, pole lamination is evenly distributed with the connecting hole that several are convenient to connect between pole lamination, and pole lamination both sides are provided with can the card-bit part of positioning wires bag; Be provided with the axle center hole that can be connected with rotating shaft in the middle of described assembly, be provided with keyway in axle center hole, described pole lamination outer surface is circumferentially provided with several dovetail grooves, and described dovetail groove can be connected projection and mate with dovetail.
In the rotor of above-mentioned a kind of hydraulic generator, described pole lamination upper end is provided with four damping holes.
In the rotor of above-mentioned a kind of hydraulic generator, between described dovetail groove and axle center hole, be provided with several louvres.
In the rotor of above-mentioned a kind of hydraulic generator, in the middle of described yoke sheet, pole piece, be provided with the ventilation hole of being convenient to dispel the heat.
In the rotor of above-mentioned a kind of hydraulic generator, described yoke, magnetic pole component, dovetail connect projection, and the angle on card-bit part is all set to rounding.
Compared with prior art, the utility model has the advantage of: dispel the heat when ventilation hole is convenient to working rotor, avoid its longevity of service to cause radiating effect bad; Be convenient to connection and the installation of rotor by the cooperation of dovetail keyway, be convenient to conveying.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of rotor of hydraulic generator, comprise the pole lamination 1 of the sheet of in layer closed assembly, described pole lamination lower end is provided with dovetail projection 2, connects projection and is connected with corresponding dovetail groove, just can realize the establishment of whole yoke by dovetail, which is for convenience detach and install, even if wherein indivedual yoke is damaged simultaneously, be also convenient for changing, reduction use cost.Pole lamination is evenly distributed with the connecting hole 3 that several are convenient to connect between pole lamination, pole lamination upper end is provided with four damping holes 4, and pole lamination both sides are provided with can the card-bit part 5 of positioning wires bag.By the connecting hole on pole lamination, realize multiple pole lamination and mutually superpose, the part that composition rotor main is wanted.Be provided with the ventilation hole 6 of being convenient to dispel the heat in the middle of pole lamination, described pole lamination, dovetail connect projection, and the angle on card-bit part is all set to rounding.Ventilation hole on pole lamination is convenient to the heat radiation of whole rotor, and rounding also can play the effect of protection coil.Be provided with the axle center hole 7 that can be connected with rotating shaft in the middle of described assembly 11, be provided with keyway 8 in axle center hole, described yoke sheet outer surface is circumferentially provided with several dovetail grooves 9, is provided with several louvres 10 between dovetail groove and axle center hole.Described dovetail groove can be connected projection and mate with dovetail.By the cooperation of dovetail keyway, the assembly and disassembly of yoke sheet and assembly can be realized, reduction use cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
