Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figures 1 to 4, a kind of rotor easy to assemble, comprise rotating shaft 100, what multi-disc rotor punching 210 was formed by stacking turn 200 and axle sleeve 300, the middle part of described rotor punching 210 offers installing hole 211 and axle sleeve 300 is positioned at installing hole 211, its outer surface is provided with multiple balancing patch 212 to described rotor punching 210 and adjacent two balancing patches 212 separate, axis hole 310 is offered in the middle part of described axle sleeve 300, axially at least one first stopper slot 320 is offered at axle sleeve 300 outer surface, described rotor punching 210 inner surface is provided with the spacing breach 213 corresponding with the first stopper slot 320, described first stopper slot 320 forms spacing hole 330 with spacing breach 213 and be provided with guide vane end stop 331 in spacing hole 330, this spacing hole 330 is square with guide vane end stop 331.
Compared with traditional rotor, this rotor adopts said structure, axle sleeve 300 is set in the middle part of rotor punching 210, each rotor punching 210 is made to be arranged on axle sleeve 300, be set in rotating shaft 100 by axle sleeve 300 again, rotor punching 210 adopts this split to design, and greatly reduces the probability producing deformation or fracture when rotor punching 210 is installed, decrease the loss of rotor punching 210, effectively control production cost.
Simultaneously, the spacing breach 213 that the first stopper slot 320 of offering of axle sleeve 300 outer surface and rotor punching 210 madial wall are offered forms spacing hole 330, the guide vane end stop 331 arranged in this spacing hole 330 plays and prevents axle sleeve 300 and rotor punching 210 from acting in relative rotation, also facilitates axle sleeve 300 and rotor punching 210 to assemble and dismantle.
In order to increase the intensity of guide vane end stop 331, further guarantee axle sleeve 300 and rotor punching 210 synchronous axial system, this spacing hole 330 is vertical with the radius of rotor punching 210, so, it is just vertical with the radius of rotor punching 210 that guide vane end stop 331 is positioned at spacing hole 330, guide vane end stop 331 overlaps with the junction of axle sleeve 300 and rotor punching 210, now, the intensity of guide vane end stop 331 is larger, it not easily produces deformation, therefore, rotor punching 210 is better with the synchronism of axle sleeve 300, if guide vane end stop 331 is vertical with the junction of rotor punching 210 with axle sleeve 300, width due to guide vane end stop 331 is less than himself length, therefore the intensity of guide vane end stop 331 is lower.
Further, described spacing hole 330 has four and adjacent two spacing holes 330 are vertical, four spacing holes 330 are uniformly distributed, rotor punching 210 is made to disperse to four guide vane end stops 331 with the opposing force of axle sleeve 300, ensure that the limit strength of guide vane end stop 331, make rotor punching 210 better with the synchronism of axle sleeve 300, four spacing holes 330 in the present embodiment are the hole number drawn afterwards after tested, its best results, but in the present embodiment, be not limited to four spacing holes 330.
As shown in Fig. 2, Fig. 3, Fig. 5, described axis hole 310 madial wall axially offers the second stopper slot 311, on described rotating shaft 100 outer surface, correspondence is provided with projection 110 and projection 110 is positioned at the second stopper slot 311, make rotating shaft 100 without the need to axle sleeve 300 interference fit, facilitate axle sleeve 300 and rotating shaft 100 dismounting, meanwhile, projection 110 coordinates with the second stopper slot 311, and axle sleeve 300 can be made with rotating shaft 100 synchronous axial system.
As shown in Figure 2, Figure 4 shows, the front end of at least one balancing patch 212 offers connecting hole 214, connecting rod (not shown) is provided with in described connecting hole 214, before rotor punching 210 is installed, first by connecting rod multiple rotor punching 210 is fixed and formed and turn 200, and then will turn and 200 to be set on axle sleeve 300, make rotor punching 210 easier for installation, fast.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
