Abstract
The invention relates to a rotor locking sleeve structure for a centrifuge. The structure comprises a locking sleeve, a motor spindle and a compression unit. A truncated-cone-shaped snapping hole is formed in the locking sleeve. The connection end of the motor spindle is in a truncated cone shape, and the shape of the connection end is matched with the shape of the snapping hole. Internal threads are arranged in the compression unit, external threads are arranged at the end of the connection end, the internal threads are matched with the external threads, and the compression unit is connected with the end of the connection end. The compression unit is a screw or a nut. By means of the structure, an assembly hole of the rotor of the structure is changed into a straight through hole, so that machining is facilitated; by the aid of the tapered sleeve connection, the assembly concentricity is guaranteed effectively; when the rotor is disassembled, only the locking screw or nut is needed to be screwed or loosened, and the locking sleeve is not needed to be dismounted, accordingly, the structure is simple and convenient to disassemble.
Description
Technical field
The present invention is used for the rotor lock tight tube structure in frozen type Centrifuge Techniques field, particularly a kind of centrifuge.
Background technology
The principle reason of centrifuge separating experiment sample is all the High Rotation Speed by driven by motor rotor, and the effect making the sample in container be subject to certain centrifugal force is isolated.
Rotor will participate in the rotary courses such as acceleration, deceleration under the drive of motor, rotor closely must be fixed on the main shaft of motor, and steady, quiet in order in ensureing to rotate through kind, the requirements such as the concentricity that both coordinate must be ensured.The fixed form of current employing, mainly contains two kinds, and one is that electric machine main shaft and rotor engagement place are done tapered, rotor is processed bellmouth fit with it, then uses nut compressing.The shortcoming of this mode on rotor, processes taper hole, difficulty in process, is difficult to ensure precision; And use procedure rotor dismounting inconvenience.Another kind is then rotor with main shaft by processing keyway and coordinate or bayonet fittings carrying out transmission, and the pure machining accuracy by groove or pin hole of this mode ensures assembly precision, high to requirement on machining accuracy, processing difficulties.
Summary of the invention
The object of the present invention is to provide a kind of rotor lock tight tube structure that effectively can reduce rotor machining difficulty.
For solving the problems of the technologies described above, the rotor lock tight tube structure of centrifuge of the present invention, comprising: lock sleeve, in described lock sleeve, be provided with hole clipping, and described hole clipping is truncated cone-shaped; Electric machine main shaft, the link of described electric machine main shaft is truncated cone-shaped, the shape of described link and the mating shapes of described hole clipping.
The rotor lock tight tube structure of described centrifuge also comprises a hold down gag; In described hold down gag, be provided with internal thread, be provided with external screw thread in the end of described link, described internal thread and described external screw thread match, and described hold down gag is connected with the end of described link.Described hold down gag is screw or nut.
The pilot hole of the rotor of the rotor lock tight tube structure of centrifuge of the present invention makes clear opening, easy to process; Taper sheath connects effectively guarantee assembling concentricity; During rotor dismounting, only need screw or unscrew lock-screw or nut, need not pull down lock sleeve, dismounting is easier.

Description of reference numerals in the rotor lock tight tube structure accompanying drawing of centrifuge of the present invention:
1-lock sleeve 2-hole clipping 3-electric machine main shaft
4-link 5-hold down gag 6-rotor
Detailed description of the invention
Be described in further detail below in conjunction with the rotor lock tight tube structure of accompanying drawing to centrifuge of the present invention.
As shown in Figure 1, the rotor lock tight tube structure of centrifuge of the present invention, comprises the elastic locking cover 1 that a hole clipping 2 is truncated cone-shaped, is equipped with lock-screw or nut is hold down gag 5.The end processing screw hole of electric machine main shaft 3 or screw rod, with hold down gag 5, the pilot hole on rotor 6 is processed into straight hole.The truncated cone-shaped hole clipping 2 of lock sleeve 1 is fitted with the link 4 of truncated cone-shaped, and the cylindrical of lock sleeve 1 coordinates with the straight pilot hole of rotor 6, and during locking, expansion sleeve produces tensioner effect, is locked by rotor 6.
The pilot hole of the rotor of the rotor lock tight tube structure of centrifuge of the present invention makes clear opening, easy to process; Taper sheath connects effectively guarantee assembling concentricity; During rotor dismounting, only need screw or unscrew lock-screw or nut, need not pull down lock sleeve, dismounting is easier.
Below the preferred embodiment of the invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
