Abstract
The utility model discloses a kind of satellite waterproof rotary shaft mechanism, comprise axostylus axostyle A, axostylus axostyle B, bearing and waterproof mechanism, bearing housing is connected on the outer wall of axostylus axostyle A, and axostylus axostyle B is connected on the outside of axostylus axostyle A by bearing housing; Waterproof mechanism comprises seal ring and spring, and it is upper that seal ring is socketed in axostylus axostyle A, on the inwall of axostylus axostyle B, by screw thread, is provided with a slip ring, between slip ring and seal ring, is provided with spring, between seal ring and bearing, is filled with seal gease; The utility model is realized the high pressure sealing between bearing and seal gease by a spring, and can carry out by slip ring the adjustment of pressure, good waterproof performance simple in structure, and by also can annotate very easily new seal gease and old seal gease being discharged by another tapped hole of tapped hole, safeguard more convenient.
Description
Technical field
The utility model relates to a kind of satellite waterproof rotary shaft mechanism, belongs to satellite rotatingshaft field.
Background technique
Because the particularity of satellite, under the pernicious ambient conditions such as navigation, higher to the sealing requirements of satellite rotatingshaft, common stuffing box bearing cannot meet this type of environmental demand.
Model utility content
The technical problems to be solved in the utility model is: overcome the poor technical problem of prior art Satellite rotating shaft sealing, a kind of novel rotating shaft waterproof mechanism is provided.
The utility model solves the technological scheme that its technical problem adopts:
A satellite waterproof rotary shaft mechanism, comprises axostylus axostyle A, axostylus axostyle B, bearing and waterproof mechanism, and described bearing housing is connected on the outer wall of axostylus axostyle A, and described axostylus axostyle B is connected on the outside of axostylus axostyle A by bearing housing;
Described waterproof mechanism comprises seal ring and spring, described seal ring is socketed on axostylus axostyle A, on the inwall of described axostylus axostyle B, by screw thread, be provided with a slip ring, between described slip ring and seal ring, be provided with spring, between described seal ring and bearing, be filled with seal gease.
As further innovation of the present utility model, the surface that described axostylus axostyle B is positioned at seal ring and position of bearings is provided with two tapped holes, on described tapped hole, screw is installed.
The beneficial effects of the utility model are:
The utility model is realized the high pressure sealing between bearing and seal gease by a spring, and can carry out by slip ring the adjustment of pressure, good waterproof performance simple in structure, and by also can annotate very easily new seal gease and old seal gease being discharged by another tapped hole of tapped hole, safeguard more convenient.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, the utility model is a kind of satellite waterproof rotary shaft mechanism, comprises axostylus axostyle A2, axostylus axostyle B1, bearing 3 and waterproof mechanism, and described bearing 3 is socketed in the outer wall of axostylus axostyle A2, and described axostylus axostyle B1 is socketed in the outside of axostylus axostyle A2 by bearing 3;
Described waterproof mechanism comprises seal ring 6 and spring 5, described seal ring 6 is socketed on axostylus axostyle A2, on the inwall of described axostylus axostyle B1, by screw thread, be provided with a slip ring 4, between described slip ring 4 and seal ring 6, be provided with spring 5, between described seal ring 6 and bearing 3, be filled with seal gease.
Described axostylus axostyle B1 is positioned at seal ring 6 and is provided with two tapped holes 7 with the surface of bearing 3 positions, on described tapped hole 7, screw is installed.
By a spring, realize the high pressure sealing between bearing and seal gease, and can carry out by slip ring the adjustment of pressure, good waterproof performance simple in structure, and by also can annotate very easily new seal gease and old seal gease being discharged by another tapped hole of tapped hole, safeguard more convenient.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this model utility technological thought, carry out various change and modification completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
