Description
Technical field
The present invention relates to a kind of incubator turntable shafting Seal Designs.
Background technique
In order to meet environmental adaptability requirement, many test equipments require to make thermocycling, and at the same time by surveying
Trial signal output, therefore conducting slip ring to be installed in rotary shaft；
Existing incubator turntable shafting sealing uses labyrinth sealing, and is furnished with deflector hole, and what is generated when for by low temperature is cold
Condensate export；This sealing means cause entire shafting very moist, can cause to corrode to bearing, cause to conducting slip ring short
Road.In cold test, the gap between main shaft and frame has dust and steam enters, and influences shafting service precision.
Summary of the invention
Its purpose of the invention, which is that, provides a kind of incubator turntable shafting Seal Design, the convenient, performance with installation and debugging
Stablize, the feature that manufacturing cost is low, and the service life of shafting and conducting slip ring can be improved.
The technical solution realizing above-mentioned purpose and taking, including incubator, incubator bottom are equipped with main shaft, and main shaft upper end is equipped with work
Make table top, work top connecting test equipment, the main shaft upper end is fixed with lower sealing plate, and conducting slip ring is fixed in main shaft lower end,
Main shaft lower end outside fixed heating plate, heating dish outside are equipped with sealed support, and sealed support upper end is equipped with upper sealing panel, upper sealing
Plate and lower sealing plate are designed to " labyrinth " formula structure, and stop-leak compound is dosed in lower seal grooves, and the sealed support is fixed
On frame, frame is arranged on the outside of incubator, and sealing ring is equipped between the incubator and frame.
Beneficial effect
The present invention has the following advantages that compared with prior art.
Heating dish is installed in main shaft outer diameter, when making low-temperature test, main shaft can be heated, avoid the generation of condensed water,
Extend shafting service life；The sealing plate under the installation of main shaft upper end, installs upper sealing panel on sealed support；Prevent dust and water
Vapour enters Bearing inner, improves shafting service precision.
1. work top is fixed on main shaft, for installing test equipment, pass through sealing plate between main shaft and sealed support
Labyrinth seal is constituted, and fills up stop-leak compound in sealing plate, forms rotary seal structure；
2. conducting slip ring is fixed on inner hole of spindle end face of flange, for test equipment signal to be transmitted to TT&C system；
3. heating dish is fixed at main shaft outer circle lower flange, when test equipment carries out low-temperature test, heating dish work is prevented
The generation of condensed water in air, protects shafting non-corrosive, and conducting slip ring works normally；
4. sealing ring is fixed between incubator and frame, completely cuts off extraneous steam and dust enters inside shafting.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawing.
Fig. 1 is present apparatus principle schematic diagram.
Specific embodiment
A kind of incubator turntable shafting Seal Design, including incubator 2,2 bottom of incubator are equipped with main shaft 8, and 8 upper end of main shaft is equipped with work
Make table top 3,3 connecting test equipment 1 of work top, as shown in Figure 1,8 upper end of the main shaft is fixed with lower sealing plate 5, under main shaft 8
Hold fixed conducting slip ring 9,8 lower end outside fixed heating plate 10 of main shaft is equipped with sealed support 6, sealed support 6 on the outside of heating dish 10
Upper end is equipped with upper sealing panel 4, and upper sealing panel 4 and lower sealing plate 5 are designed to " labyrinth " formula structure, and in lower 5 groove of sealing plate
Dose stop-leak compound, the sealed support 6 is fixed on frame 7, the setting of frame 7 in the outside of incubator 2, the incubator 2 and frame 7 it
Between be equipped with sealing ring 11.
The conducting slip ring 9 is fixed on inside main shaft 8, and conducting slip ring 9 is rotated with main shaft 8, and conducting slip ring 9 is by test equipment
1 signal is exported to external TT&C system.
Embodiment
As shown in Figure 1, the present embodiment is used for incubator turntable shafting Seal Design, including：Test equipment 1, incubator 2, work
Table top 3, upper sealing panel 4, lower sealing plate 5, sealed support 6, frame 7, main shaft 8, conducting slip ring 9, heating dish 10 and sealing ring 11.
As shown in Figure 1, work top 3 is fixed on main shaft 8, rotated for installing test equipment 1, and with shafting.
Upper sealing panel 4 and lower sealing plate 5 are installed between main shaft 8 and sealed support 7, constitute labyrinth sealing knot between two sealing plates
Structure, and stop-leak compound is filled up in lower sealing plate 5, complete rotatory sealing function.
2. conducting slip ring 9 is fixed on 8 inner hole flange lower end surface of main shaft, for 1 signal of test equipment to be transmitted to observing and controlling system
System, is in real time acquired sensitive signal；
3. heating dish 10 is fixed at 8 outer circle lower flange of main shaft, room temperature and hot test formula are carried out in test equipment 1, is added
Hot plate 10 does not work；When test equipment 1 carries out low-temperature test, heating dish 10 works, and heats to main shaft 8, prevents in main shaft 8
The generation of condensed water；Ensure that shafting non-corrosive, conducting slip ring 9 work normally；
4. sealing ring 11 is fixed between incubator 2 and frame 7, completely cuts off extraneous steam and dust enters inside shafting.
