Brief description of the drawings
Fig. 1 be the utility model proposes a kind of airtightness test table for car deceleration device housing structural representation
Figure.
Specific embodiment
As shown in figure 1, Fig. 1 be the utility model proposes a kind of airtightness test table for car deceleration device housing
Structural representation.
Reference picture 1, the utility model proposes a kind of airtightness test table for car deceleration device housing, including frame
1, the frame 1 is provided with decelerator end seal 2；The top of the end seal 2 is provided with reducer shaft seal 3, described to subtract
Fast device shaft seal 3 is connected by extension spring 4 with supporting plate 5, and the supporting plate 5 is lived by retractable vertical rod 6 with the frame 1
Dynamic connection；The decelerator end seal 2 and reducer shaft seal 3 can be tightly connected with reducer shell K, and enclose therewith
Into detection cavity；The detection cavity is connected by by detection pipe with pressure detecting instrument 7, also by exhaust tube and extraction sector
8 connections；Controller 9 and display screen 10 are additionally provided with the frame 1, the input of the controller 9 electrically connects pressure detecting instrument 7,
Its output end electrically connects extraction sector 8 and display screen 10.
When air-tight test is carried out to reducer shell K, the differential mechanism end of reducer shell K to be detected is placed on
On decelerator end seal 2, the length of vertical rod 6 is adjusted, make reducer shaft seal 3 near reducer shell K.Start extraction sector
8 carry out pre- pumping, and pressure difference is acted on, and reducer shaft seal 3 is firmly adjacent on reducer shell K, and makes reducing gearbox
Body K, decelerator end seal 2 and reducer shaft seal 3 enclose detection cavity.Pumping is proceeded by extraction sector 8,
After detecting that the pressure values in cavity reach predetermined value, close extraction sector 8 to stop pumping.After the scheduled time, observation display
Whether the pressure value for shielding display is maintained in a scope for stabilization.If maintaining in the scope of stabilization, hermetic seal is good；Instead
It, then gas leakage.
After the completion for the treatment of that reducer shell K gas sealing abilities are detected, because reducer shaft seal 3 is firmly adjacent in decelerator
On housing K, it has not been convenient to which reducer shell K's smoothly removes.Therefore, be also associated with air inlet pipe on the exhaust tube, it is described enter
Tracheae is provided with intake valve 13.
Used as preferred scheme, decelerator end seal 2 and the reducer shaft seal 3 are towards reducer shell K mono-
Side is equipped with sealing gasket, and the detection cavities seals are functional, and testing result is more accurate.
As preferred scheme, the alarm mechanism 11 electrically connected with the output end of controller 9 is additionally provided with the frame 1,
During generation gas leakage, alarm mechanism 11 sends alarm signal automatically, and specifically, the alarm mechanism 11 is buzzer, to carry
The attention of awake testing staff.
Used as preferred scheme, the exhaust tube is provided with flow control valve 12.
The utility model proposes a kind of airtightness test table for car deceleration device housing, simple to operate, workload
Small, testing result is accurate, reliable, and detection efficiency is high.
