Abstract
The invention provides a high-rotation-speed impeller and rotor linking mechanism. The linking mechanism comprises an impeller (1), a rotor (5) and a locking nut (2), wherein the rotor (5) and the impeller (1) are in taper fit of 1:50; the locking nut (2) is connected with the rotor (5); and the connection between the inner hole of the impeller and the shaft of the rotor has certain interference which is controlled by the screw-in distance of the locking nut (2). The linking mechanism solves the problems of the mounting and dismounting of the high-rotation-speed impeller and the shaft of the rotor, aims to realize the convenient mounting and dismounting of the impeller and the shaft of the rotor and has good repeat mounting performance. The mounting between the impeller and the shaft is completely performed in a cool state and the impeller does not need to be heated; the fit surface between the inner hole of the impeller and the shaft of the rotor cannot be damaged during the mounting and the dismounting which are convenient.
Description
(1) technical field
The present invention relates to impeller and rotor, be specifically related to a kind of have high-revolving impeller and rotor linking mechanism.
(2) background technique
The high speed rotor impeller adopts big interference fit with rotor shaft generally speaking, in case impeller gets loose under the working rotor state, and then rotor dynamic balancing is exerted an influence.Generally, axle journal adopts the cylndrical surface to cooperate with the impeller endoporus, and this often brings very burden to dismounting, impeller is heated its distortion itself and rotor shaft are separated, dismantle by force by external force and to tend to make axis hole or axle journal fitting surface to pull, and then have influence on assembling next time.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby a kind of high rotating speed impeller and rotor linking mechanism are provided, the high rotating speed impeller of solution and rotor shaft installing/dismounting problem make every effort to make the mounting or dismounting of impeller and rotor shaft convenient, and it is good to repeat assembling.The present invention includes impeller, rotor, impeller and rotor adopt taper fit.
A kind of have high-revolving impeller and a rotor linking mechanism, comprise that impeller 1 and rotor 5 adopt 1: 50 taper fit, for guaranteeing that impeller 1 and rotor 5 do not get loose when the high rotating speed, the axle of impeller endoporus and rotor being connected of fitting surface have certain magnitude of interference, the distance that magnitude of interference relies on locking nut 2 to screw in is controlled, locking nut 2 is connected with rotor 5, screw in for ease of locking nut 2, with spanner that rotor 5 is fixing, concrete grammar is the axle head of spanner plate being lived rotor 5, be square toes 9, locking plate 3 connects locking nut 2, and locking plate 3 is used for locking nut 2 final rigging position lockings, to dismantle pressing plate spare 6 is pressed on the rotor 5, the hole, relevant position penetrates 6 demounting bolts 7 with circumferential order on dismounting pressing plate 6, and is screwed in the corresponding dismounting of the impeller screw, treat that apical axis bolt 8 and rotor 5 are close to fully after, continue to turn apical axis bolt 8, make impeller 1 and rotor 5 fitting surfaces loosening, owing to used taper fit, impeller 1 can easy and rotor 5 disengagements.
Advantage of the present invention: impeller is to carry out under cold state with the axle assembling fully, and impeller need not heat; Can not damage the fitting surface of the axle of impeller endoporus and rotor in assembling and the unloading process; Assembling and convenient disassembly.

Fig. 1 type high speed rotor impeller installing figure;
Fig. 2 type high speed rotor impeller demolition schematic representation.
(5) embodiment
Below, in conjunction with the accompanying drawings, the present invention is further described:
As shown in Figure 1: impeller 1 adopts 1: 50 taper fit with rotor 5, for guaranteeing that impeller 1 and rotor 5 do not get loose when the high rotating speed, the impeller endoporus has certain magnitude of interference with the axle of rotor being connected of fitting surface, the distance that magnitude of interference relies on locking nut 2 to screw in is controlled, screw in for ease of locking nut 2, with spanner that rotor 5 is fixing, concrete grammar is the axle head of spanner plate being lived rotor 5, i.e. square toes 9 among the figure, locking plate 3 is used for locking nut 2 final rigging position lockings, and rotor 5 rotates by the connection impeller of flat key 4.
As shown in Figure 2: will dismantle pressing plate spare 6 and be pressed on the rotor 5, the hole, relevant position penetrates demounting bolt 7 on dismounting pressing plate 6,6 of circumference, and be screwed in the corresponding dismounting of the impeller screw, after treating that apical axis bolt 8 and rotor 5 are close to fully, continue to turn apical axis bolt 8, make impeller endoporus 1 loosening with the axle fitting surface of rotor 5, owing to used taper fit, impeller 1 can easy and rotor 5 disengagements.
