Description
Technical field:
The present invention relates to a kind of structure being tightly fixed on rotor by pure iron mortice lock and the method that is locked, it belongs to centrifugal fan technical field.
Background technology:
In existing centrifugal fan, generally include rotor, it is installed on the magnetic bearing above rotor, and pure iron sheet, in prior art, pure iron sheet is typically by hot cover process and rotor elastic conjunction, strike flange at end to fix, magnetic bearing (not with rotor contact) is placed in its top position, but this kind of connected mode often results in pure iron sheet outer ring stress after rotor runs for a long time and gradually deforms, and the fixed form of above-mentioned pure iron sheet flange can loosen after rotor long-play, and then cause that whole pure iron sheet comes off, the strong influence normal operation of rotor.
Therefore, necessary prior art improves to solve the deficiency of prior art.
Summary of the invention:
In order to solve above-mentioned technical problem, the present invention provides a kind of structure being tightly fixed on rotor by pure iron mortice lock and the method that is locked.
The present invention adopts the following technical scheme that a kind of structure being tightly fixed on rotor by pure iron mortice lock, described pure iron sheet is installed on rotor, described rotor is positioned at the position below pure iron sheet and is arranged with a magnetism-isolating loop, together with described magnetism-isolating loop is close to pure iron sheet, described pure iron sheet and magnetism-isolating loop are provided with the two is locked in attachment screw together, described magnetism-isolating loop is hollow form column structure wide at the top and narrow at the bottom, described magnetism-isolating loop includes top and bottom, the outward flange diameter on described top is more than the outward flange diameter of bottom, described magnetism-isolating loop is provided with through in magnetism-isolating loop upper and lower surface and the through hole that is surrounded on rotor periphery, described attachment screw is installed on the top of magnetism-isolating loop, the bottom of described magnetism-isolating loop is provided with rotor sleeve.
Further, described attachment screw is several of a certain circumferencial direction spaced set on pure iron sheet.
The present invention also adopts the following technical scheme that a kind of method that is locked being tightly fixed on rotor by pure iron mortice lock, and it comprises the following steps that
(1). the pure iron sheet processed and magnetism-isolating loop are connected fastening by attachment screw, and the end face car of attachment screw and pure iron sheet is put down;
(2). by rotor sleeve and the above-mentioned pure iron sheet assembled and magnetism-isolating loop by together with hot cover process is assemblied in;
(3). by rotor and the structure assembled in above-mentioned steps (2) by together with hot cover process is assemblied in.
There is advantages that the present invention passes through the side installation settings magnetism-isolating loop at pure iron sheet, magnetism-isolating loop and pure iron sheet are connected together by attachment screw, considerably increase the stability that pure iron sheet is connected with rotor, decrease the probability that pure iron sheet comes off.
Accompanying drawing illustrates:

Detailed description of the invention:
Refer to shown in Fig. 1 and Fig. 2, pure iron mortice lock is tightly fixed in the structure on rotor by the present invention, pure iron sheet 3 is installed on rotor 1, rotor 1 is positioned at the position above pure iron sheet 3 one magnetic bearing 2 is installed, wherein magnetic bearing 2 is installed on the support of bearing 6, rotor 1 is positioned at the position below pure iron sheet 3 be arranged with one be close to pure iron sheet 3 together with magnetism-isolating loop 4, wherein pure iron sheet 3 with magnetism-isolating loop 4 is provided with by the two locking be installed on together with attachment screw 5. Wherein attachment screw 5 is several of a certain circumferencial direction spaced set on pure iron sheet 3.
In the present invention, magnetism-isolating loop 4 is hollow form column structure wide at the top and narrow at the bottom, and magnetism-isolating loop 4 includes top and bottom, the outward flange diameter of its middle and upper part more than the outward flange diameter of bottom, be provided with through in magnetism-isolating loop 4 in magnetism-isolating loop 4 upper and lower surface and the through hole (sign) that is surrounded on rotor 1 periphery. Wherein attachment screw 5 is installed on the top of magnetism-isolating loop 4. The bottom of magnetism-isolating loop 4 is provided with rotor sleeve 7.
Pure iron mortice lock is tightly fixed on the method that is locked on rotor by the present invention, comprises the following steps that
(1). first the pure iron sheet processed and magnetism-isolating loop are connected fastening by attachment screw, and the end face car of attachment screw and pure iron sheet is put down, as shown in Figure 3;
(2). by rotor sleeve and the above-mentioned pure iron sheet assembled and magnetism-isolating loop by together with hot cover process is assemblied in, as shown in Figure 4;
(3). by rotor and the structure assembled in above-mentioned steps (2) by together with hot cover process is assemblied in.
The concept of hot cover process is explained: assume have two parts to need to be assembled together below by a simply example, one outer diameter of a circle is 35.01mm, the diameter of another endoporus is 35mm, now it is accomplished by there will be this heat parts of endoporus, according to principle of expanding with heat and contracting with cold, when being heated to uniform temperature, the internal diameter of its endoporus will be greater than 35.01mm, now just two parts can be assembled together, after assembling placement is cooled to room temperature, the size restoration of part is to initial value, and two parts will fit tightly together.
By the side installation settings magnetism-isolating loop at pure iron sheet in the present invention, magnetism-isolating loop and pure iron sheet are connected together by attachment screw, considerably increase the stability that pure iron sheet is connected with rotor so that pure iron sheet is not easily inhaled by magnetic bearing and come off.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be regarded as protection scope of the present invention.
