Description
Technical field
The utility model relates to a kind of main shaft air curtain safeguard structures of brake disc Special Purpose Machine for Processing, belong to machine-building neck
Domain.
Background technique
Since brake disc is mostly spheroidal graphite gray cast iron material, a large amount of tiny dust, lathe master are generated in process
Axis can generate air-flow inside the state flowering structure that runs at high speed, and the generation pressure difference inside and outside main shaft be caused, so that dust is inhaled into
Inside main shaft, and then influence main shaft bearing life and precision.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of protection of the main shaft air curtain of brake disc Special Purpose Machine for Processing
Structure, avoiding lathe by triple safeguard structures, the impurity such as dust and steam enter main shaft in the process of running, and extending main shaft makes
Use the service life.
In order to solve the above problem, the specific technical solution of the utility model is as follows: a kind of brake disc Special Purpose Machine for Processing
Main shaft air curtain safeguard structure, including main shaft, main shaft excircle suit are connected with casing, and casing is different knots about axis two sides
Structure, axis side are air inlet pipe, and the air inlet bore ends of air inlet pipe are equipped with air curtain area, and the other end of air inlet pipe is port, and axis is another
Side is discharge structure, and casing front end sleeve load is connected to front end gland, and front end gland excircle is set with shield.When main shaft revolves
It will be entered by filtered air by sleeve bottom stomata while turning, be discharged by front end gland gas hole, with main shaft air curtain
Annular groove forms air curtain sealing area, increases main shaft internal pressure, realizes external dust, water
Vapour etc., which can not be inhaled into, achievees the purpose that protection.
The discharge structure are as follows: front end gland and main shaft contact position are equipped with drainage area, and drainage area side is equipped with discharge outlet,
Discharge outlet extends to shield inner wall.For prevent from occurring because of main shaft inside and outside temperature difference and because of the influence of gas source degree of drying
Condensed water processes drainage hole in drive end bearing bracket, as further safeguard procedures.
Sealing ring is set between the main shaft and shield.
Sealing caulking ring is set between the main shaft and front end gland.
Clearance fit connects between the shield and front end gland.
The utility model bring has the beneficial effect that the design structure for generated powder in brake disc process
Dirt is realized to form the protection of the first sublevel first by the small―gap suture of shield and ring flange；Pass through blow out air inside main shaft again
Realize internal positive pressure, dust avoided to suck, then and by main shaft rotate in form air curtain in seal groove and make inside and outside isolation, then together
When by the condensed water that drainage hole would be possible to generate taken precautions against and be can be realized effective discharge, form second layer protection；Most
Mazy sealing structure is formed by sealing caulking ring and front end gland afterwards, forms third layer protection.Form multilayer proofing effectively
Dust and cooling water are completely cut off.Improve the service life of main shaft or even lathe itself.
Detailed description of the invention
Fig. 1 is the main shaft air curtain safeguard structure schematic diagram of brake disc Special Purpose Machine for Processing.
Fig. 2 is Fig. 1 partial enlargement diagram.
Fig. 3 is air curtain area schematic diagram.
Fig. 4 is condensate water-proof discharge structure schematic diagram.
Specific embodiment
As shown in Figures 1 to 4, a kind of main shaft air curtain safeguard structure of brake disc Special Purpose Machine for Processing, including main shaft 5, it is main
5 excircle of axis suit is connected with casing 1, and casing 1 is different structure about axis two sides, and axis side is air inlet pipe 1-1, air inlet
6 end of air inlet of pipe 1-1 is equipped with air curtain area 9, and the other end of air inlet pipe 1-1 is port 11, and the axis other side is discharge structure,
1 front end sleeve load of casing is connected to front end gland 2, and gland 2 excircle in front end is set with shield 3,3 inner wall of shield simultaneously with master
Axis 5 and the contact of 2 excircle of front end gland.
The discharge structure are as follows: front end gland 2 and 5 contact position of main shaft are equipped with drainage area 8, and 8 side of drainage area is equipped with row
The mouth of a river 10, discharge outlet 10 extend to 3 inner wall of shield.
Sealing ring 4 is set between the main shaft 5 and shield 3.
Sealing caulking ring 7 is set between the main shaft 5 and front end gland 2.
Clearance fit connects between the shield 3 and front end gland 2.
Main shaft 5 rotate simultaneously by 1 lower end of casing connect dried and clean gas source, gas pass through front end gland 2 into
Stomata 3 enters air curtain area 9, forms normal pressure inside main shaft 2 while forming air curtain, prevents main shaft 2 from being formed when rotated negative
The dust that processing generates and steam sucking main shaft 2 are caused the damage of bearing by pressure gas stream.
Small―gap suture is formed between shield 3 and front end gland 2, prevents iron filings from entering guard plot and realizes first layer protection.
Shield 3 and main shaft 5 prevent cooling water and dust along with joint close sealing ring 4 is placed between mating surface after closing
Gap enters inside main shaft 5.
Enter when gas passes through air inlet 6 in 5 rotation status of main shaft, will form air curtain area 9, realize the mesh of air curtain protection
's.
Drainage area 8 prevents because of 5 internal-external temperature difference of main shaft and enters the condensed water of gas dry factor appearance in drainage area 8
It collects and main shaft is discharged by discharge outlet 10.
Sealing caulking ring 7 and front end gland 2 form labyrinth sealing, further protect, and achieve the effect that improve the main shaft service life.
Above-described is only the preferred embodiment of the utility model.It should be pointed out that for the ordinary skill people of this field
For member, without departing from the principle of this utility model, several variations and modifications can also be made, also should be regarded as belonging to this
The protection scope of utility model.
