Description
Technical field
The utility model is related to a kind of mechanical arm transmission main shaft mechanism technology field for completing transferring work piece, more particularly to
A kind of twin shaft vacuum sealing transmission mechanism.
Background technology
Vacuum equipment, especially high-vacuum apparatus for sealing property require it is high, its should have quiet dynamic sealing performance can
It is high by performance, the features such as long service life.There are several forms, a rubber sealing, two ripples what high vacuum transmission seal was commonly used
The seal of tube, three are magnetic transmission seal, four magnet fluid sealings etc., and wherein the utility model uses magnet fluid sealing.Magnetic fluid is made
For new function material, magnet fluid sealing had not only had the mobility of liquid but also the magnetic with solid magnetic material, was by diameter
For the magnetic retention particle of nanometer scale (less than 10 nanometers), base load liquid (being also media) and interfacial agent three mixing
Into a kind of stabilization colloidal liquid.The fluid nonmagnetic attraction in static state, when externally-applied magnetic field is acted on, just shows magnetic
Property.Its feature is that traditional sealing means are incomparable：1st, leakage rate is less than 10 at normal temperatures and pressures-12Pa·m3/ s,
Sealing to the material such as hypertoxic, inflammable, explosive is significant；2nd, long service life, due to its design feature, makes after measured
With for more than 10 years.Maintenance maintenance is avoided to bother；3rd, pollution-free, due to no mechanical wear, magnetic fluid seal ring is not produced
The particle of contaminated system, in addition, the magnetic fluid of low-steam pressure has even in more than 10-6Pa to high vacuum seal reliability
Extremely important effect.
Utility model content
Weak point present in regarding to the issue above, the utility model provides a kind of twin shaft vacuum sealing transmission mechanism,
Make its simple in construction, be convenient to process and mount, good seal performance, unfailing performance is high, while sealing property is excellent to ensure that twin shaft is moved
The demand of conveying and the sealing of power.
In order to solve the above problems, the utility model provides a kind of twin shaft vacuum sealing transmission mechanism, wherein, including transmission
Axle and flange form are without guide bracket type brake, and the flange form is arranged on the lower end of the power transmission shaft without guide bracket type brake, described
Power transmission shaft includes main shaft and hollow shaft, and the main shaft is arranged on inside the hollow shaft, and the main shaft is hinged with the hollow shaft,
Pass through interior magnet fluid sealing between the main shaft and the hollow shaft.
It is preferred that, also including housing, the housing is internally provided with the power transmission shaft, the housing and the hollow shaft
Between pass through outer magnet fluid sealing.
It is preferred that, the housing is sealing structure with the power transmission shaft, and knife is used between the housing and the power transmission shaft
Mouth metal sealing.
It is preferred that, the bottom of the housing is provided with the flange form without guide bracket type brake.
It is preferred that, the power transmission shaft is Two axle drive structure.
Compared with prior art, the utility model has advantages below：
The utility model is simple in construction, is convenient to process and mount, good seal performance, and unfailing performance is high, while sealing property is excellent
The demand of good conveying and the sealing that ensure that double-shaft power.

In the present embodiment, hollow shaft 2 is hinged with housing 3, and main shaft 1 is hinged with hollow shaft 2, and housing 3 is fixed on vacuum cavity
Upper use edge of a knife metal sealing, flange form is fixed on housing 3 to prevent that hollow shaft 2 from need not turn without guide bracket type brake 6
Rotated when dynamic, interior magnetic fluid 4 is placed between hollow shaft 2 and main shaft 1 as sealing, and outer magnetic fluid 5 is placed in hollow shaft 2 and housing 3
Between as sealing.The utility model is simply easy to process, install simple, while the excellent double-shaft power that ensure that of sealing property
Conveying and the demand of sealing.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.A variety of modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can in other embodiments be realized in the case where not departing from spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
