Description
Technical field
It the utility model is related to vacuum dynamic seal engineering device technique field, and in particular to a kind of combined magnetic force is driven vacuum moving
Sealing device.
Background technology
Vacuum dynamic seal on vacuum equipment is widely used.All vacuum equipments all be unable to do without vacuum sealing, own
Vacuum sealing be all afraid of to leak.And all vacuum equipments, leak detection is all most troublesome thing, realizes that vacuum static seal compares appearance
Easily, realize that vacuum dynamic seal is relatively difficult, ensure that vacuum dynamic seal does not leak and be more difficult to.
In vacuum equipment, the sealed connection required for motion is delivered in vacuum tank calls vacuum dynamic seal and connected
Connect.Dynamic sealing connection example in various vacuum equipments is a lot, and such as the power of various positive-displacement vacuum pump rotary shafts inputs;Vacuum
The opening and closing of valve;The transmission of the mechanisms such as vacuum melting furnace, the feeding of vacuum heat treatment furnace, drawing ingot, casting;Vacuum coating
Rotation of equipment work-piece frame etc..
Vacuum dynamic seal attachment structure and the sealing structure to work at ambient pressure are different.This sealing is except requiring it
Structure has outside enough intensity, life-span and rational appearance and size in itself, and the characteristics of for vacuum, it must also be ensured that sealing
Reliability, i.e. dynamic sealing, which are connected in long-term work, must assure that external environment gas leakage or maintains gas leakage not into vacuum tank
Within the scope of design requirement.
Utility model content
The purpose of this utility model be to provide it is a kind of combine it is reasonable, suitable for linear or multi-direction movement, anti-leak
Combined driving vacuum dynamic seal device.
The utility model is achieved through the following technical solutions：
A kind of combined magnetic force is driven vacuum dynamic seal device, including rotating shaft, rotor, rolling bearing and cartridge seal set,
The rotating shaft side is connected with rotor, opposite side connecting trays, rolling bearing, the rotor is provided between the rotor and rotating shaft
Including being connected including interior magnet rotor and outer magnet rotor, the rotating shaft with interior magnet rotor, the interior magnet rotor outer layer is provided with outer magnetic
Rotor, the rotating shaft outer layer are provided with cartridge seal set.
Further, bearing guide rail bracket is installed by flange in the rotating shaft, the rotating shaft is through bearing guide frame with holding in the palm
Disk is connected.
Further, the rotating shaft is provided with cartridge seal set from bearing guide frame end to rotor-end.
Further, the interior magnet rotor is located in cartridge seal set, and it is outer that the outer magnet rotor is located at cartridge seal set.
The beneficial effects of the utility model are：The utility model proposes it is a kind of be applied to it is linear or multi-direction movement
Sealing structure, this structure are not influenceed using magnetic drives on vacuum, can reach zero leakage, feed rod and vacuum vessel wall
It is not in contact, the dynamic sealing of change torque transmission is reliable into static seal, sealing property, except seal isolation set during translatory movement
Outside the influence of pressure difference, other load are not subject to, without motion friction between seal, not only eliminate to the dirt in vacuum tank
Dye, and also eliminate friction power loss.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：1st, bearing guide frame, 2, cartridge seal set, 3, rolling bearing, 4, outer magnet rotor, 5, interior magnet rotor, 6, turn

Rotor includes interior magnet rotor 5 and outer magnet rotor 4, and rotating shaft 6 is connected with interior magnet rotor 5, and the interior outer layer of magnet rotor 5 is provided with outer magnet rotor
4, the outer layer of rotating shaft 6 is provided with cartridge seal set 2.
In the technical program, bearing guide rail bracket 1 is installed by flange 7 in rotating shaft 6, rotating shaft 6 through bearing guide frame 1 with
Pallet 8 is connected.
In the technical program, rotating shaft 6 is provided with cartridge seal set 2 from the end of bearing guide frame 1 to rotor-end.
In the technical program, interior magnet rotor 5 is located in cartridge seal set 2, and outer magnet rotor 4 is located at outside cartridge seal set 2.
The utility model proposes it is a kind of be applied to linear or multi-direction movement sealing structure, this structure uses magnetic force
Transmission does not influence on vacuum, can reach zero leakage, and feed rod is not in contact with vacuum vessel wall, becomes the dynamic of torque transmission
It is sealed into that static seal, sealing property are reliable, during translatory movement in addition to the influence of seal isolation set pressure difference, is not subject to it
His load, without motion friction between seal, is not only eliminated to the pollution in vacuum tank, and also eliminate frictional work
Consumption.
Particular embodiments described above, to the technical problem, technical scheme and beneficial effect of solution of the present utility model
It is further described, should be understood that and the foregoing is only specific embodiment of the utility model, not
It is all within the spirit and principles of the utility model for limiting the utility model, any modification for being made, equivalent substitution, change
Enter, should be included within the scope of protection of the utility model.
