Description
Technical field
The utility model relates to vacuum pump, particularly a kind of vacuum pump rotor driving mechanism without leakage of oil, low noise.
Background technique
Traditional mechanical its structure of vacuum pump rotor driving mechanism is shown in Fig. 1.As shown in the figure: motor 1 rotor driven 3 rotates and connects transmission motion by rigidity axle 2.Sealed by seal ring 5 between axle 2 and vacuum pump housing 4.
The drawback of this sealing is:
1, axle 2 is not stopped transport for a long time and is turned, and seal ring 5 easily weares and teares.
2, seal ring 5 is easily aging.
3, axle 2 and seal ring 5 rub and produce noise.
The consequence that above-mentioned drawback finally causes is that vacuum pump leakage of oil and noise are large.
Model utility content
The problems such as the purpose of this utility model is to provide a kind of vacuum pump rotor driving mechanism without leakage of oil, low noise, mainly solves the defect existing for above-mentioned prior art, and it adopts magnetic couple transmission campaign, the leakage of oil avoiding traditional oil-sealing measures to produce.
For achieving the above object, the utility model realizes like this.
Without a vacuum pump rotor driving mechanism for leakage of oil, low noise, it comprises motor, axle and rotor; It is characterized in that: this motor connects a connecting body by the first axle, first magnet is installed inside this connecting body, vacuum pump housing is arranged between the first magnet, also have the second axle being provided with the second magnet between the shell wall of the vacuum pump housing between this first magnet, one end of this second axle connects rotor; The position of this second magnet corresponds to the position of the first magnet.
The described vacuum pump rotor driving mechanism without leakage of oil, low noise, it is characterized in that: this second axle is arranged with shaft attachment, this second magnet is installed on shaft attachment.
Above structure, the utility model has technique effect superior as follows.
1, when the utility model uses, drive the first axle to rotate by motor, this first axle drives connecting body to rotate further, due to the effect of the magnetic couple of the first magnet and the second magnet, shaft attachment is by magneto drive, and make corresponding sports and drive the second axle to rotate, correspondingly rotor driven rotates.Like this, the rotation of motor just when with vacuum pump housing in completely isolated, give rotor 3, without the need to sealing moving through magnetic couple transmission.
2, the utility model is by said structure, and the phenomenon of leakage of oil and corresponding friction noise can be avoided to produce.

In figure: 1-motor; 21-first axle; 22-second axle; 3-rotor; 4-vacuum pump housing; 6-connecting body; 7-first magnet; 8-second magnet; 9-shaft attachment.
Embodiment
Refer to Fig. 2, it is a kind of vacuum pump rotor driving mechanism without leakage of oil, low noise of the utility model.As shown in the figure: it comprises motor 1, axle and rotor 3; This motor 1 connects a connecting body 6 by the first axle 21, first magnet 7 is installed inside this connecting body 6, vacuum pump housing 4 is arranged between the first magnet 7, also have the second axle 22 being provided with the second magnet 8 between the shell wall of the vacuum pump housing 4 between this first magnet 7, one end of this second axle 9 connects rotor 3; The position of this second magnet 8 corresponds to the position of the first magnet 7.
When the utility model uses, the first axle 21 is driven to rotate by motor 1, this first axle 21 drives connecting body 6 to rotate further, due to the effect of the magnetic couple of the first magnet 7 and the second magnet 8, shaft attachment 9 is by magneto drive, make corresponding sports and drive the second axle 22 to rotate, correspondingly rotor driven 3 rotates.Like this, the rotation of motor 1 just when with vacuum pump housing 4 in completely isolated, give rotor 3, without the need to sealing moving through magnetic couple transmission.
The utility model, by said structure, can avoid the phenomenon of leakage of oil and corresponding friction noise to produce.
Be only preferred embodiment of the present utility model in sum, be not used for limiting practical range of the present utility model.Namely all equivalences done according to the content of the utility model claim change and modify, and all should be technology category of the present utility model.
