Description
Technical field
The utility model is related to propeller drive technical field, more particularly to a kind of universal structure.
Background technology
Marine surface propeller propelling unit fixed shell conventional at present and propeller shaft housing it is general by universal ball end come
Connection, to realize that the propeller shaft in propeller shaft housing can be adjusted with left and right up and down while rotation；Generally in fixation
Internal Spherical Surface is processed in housing, the machining on spherical end being connected with propeller shaft housing goes out spherical outside surface.Fixed shell in this configuration
Internal Spherical Surface not only need to bear the thrust from propeller, in addition it is also necessary to bear due to propeller shaft frequently up and down rotate produce
Raw frictional force.Due to being all in normal operation, around fixed shell fresh water or seawater, it is necessary to select corrosion resistance
Can be good, intensity is preferable, and wear-resisting material, and this material is difficult to find, for the intensity and corrosion-resistant, reality of agent structure
Selection is all to compare the intensity and corrosion resistance that stress material in the application of border；Therefore Internal Spherical Surface in fixed shell and bulb
Spherical outside surface inevitably occurs abrasion after long-term use, and the gap for causing bulb to coordinate increases, and causes whole propulsion dress
The vibration put is increased, and therefore sealing system can also become fragile, leakage easily occur, and fixed shell can only be changed during maintenance
And bulb, maintenance cost is high and time-consuming, it is impossible to meet the demand in market.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of universal structure, its simple structure, system
Low cost is made, easy to maintenance quick, intensity high corrosion resistance is good, and with very strong abrasive resistance.
The utility model solve technical scheme that its technical problem used for：
A kind of universal structure, including fixed shell and universal ball end, the spherical outside surface front portion of the universal ball end and set casing
A bushing is embedded between circle, the fixed shell inner ring is provided with a contiguous block in vivo, the contiguous block inner ring and bushing
Inner surface is fitted with the spherical outside surface of universal ball end, and the first sealing ring is provided between the outer ring of the bushing and fixed shell,
The second sealing ring is provided between the inner ring and universal ball end of the bushing, is provided between the inner ring and universal ball end of the contiguous block
3rd sealing ring.
Used as the improvement of above-mentioned technical proposal, the front portion of the bushing Internal Spherical Surface is provided with some oil for storing lubricating oil
Groove.
Used as the improvement of above-mentioned technical proposal, the inner ring of the bushing is provided with some mounting grooves, the second sealing ring peace
In mounting groove, second sealing ring uses V-shaped seal ring or O-ring seal.
Used as the improvement of above-mentioned technical proposal, the rear portion of the contiguous block inner ring is provided with one and stretches out block, and the block that stretches out sets
Have one for install the 3rd sealing ring groove.
Used as the improvement of above-mentioned technical proposal, the bushing is made of bronze.
The beneficial effects of the utility model have：
A kind of universal structure of the present utility model, is equipped with bushing and contiguous block between fixed shell and universal ball end,
The directly contact between universal ball end and fixed shell or abrasion are avoided, the universal structure is not only simple in structure, manufacturing cost
Low, easy to maintenance quick, intensity high corrosion resistance is good, and with very strong abrasive resistance.
Brief description of the drawings
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail, wherein：
Fig. 1 is the sectional view of the utility model embodiment；
Fig. 2 is the sectional view of bushing in the utility model embodiment.
Specific embodiment
Referring to Fig. 1, a kind of universal structure of the present utility model, including fixed shell 2 and universal ball end 3, the multi-directional ball
First 3 spherical outside surface is anterior to be embedded with a bushing 5 and the inner ring of fixed shell 2 between, and the inner ring of the fixed shell 2 is provided with a connection
Block 4, inner chamber one end of the fixed shell 2 is provided with internal thread, and the outer ring of the contiguous block 4 is provided with mutually revolves with the internal thread of fixed shell 2
The external screw thread for connecing, the inner ring of the contiguous block 4 is adjacent to the spherical outside surface of universal ball end 3 and is connected, the inner ring diameter of contiguous block 4 and universal ball end
The external diameter of 3 outer ring is consistent, while needing to polish the inner ring of contiguous block 4, the inner ring for reducing contiguous block 4 is outer with universal ball end 3
The friction of circle, protection universal ball end 3 is not damaged by；Contiguous block 4 is made using the bronze material of intensity highly corrosion resistant, due to
Whole universal structure assembly precision requirement is strict, therefore contiguous block 4 need to be finished.The inner ring of the contiguous block 4 with it is universal
The 3rd sealing ring 10 is provided between bulb 3, the rear portion of the inner ring of the contiguous block 4 is provided with one and stretches out block 11, and the block 11 that stretches out sets
Have one for install the 3rd sealing ring 10 groove, the 3rd sealing ring 10 can prevent impurity in fresh water or seawater into universal
In structural body, prevent from causing to be worn and torn during universal structure use.
With further reference to Fig. 2, the spherical outside surface of the inner surface of the inner ring of the contiguous block 4 and bushing 5 with universal ball end 3 is affixed
Close, the first sealing ring 8 is provided between the outer ring of the bushing 5 and fixed shell 2, the first sealing ring 8 is for seal cartridge 5 and admittedly
Gap between fixed shell 2, is provided with the second sealing ring 9 between the inner ring and universal ball end 3 of the bushing 5, the bushing 5 it is interior
Circle is provided with some mounting grooves 7, and second sealing ring 9 is arranged in mounting groove 7, and second sealing ring 9 uses V-shaped seal ring
Or O-ring seal, the front portion of the Internal Spherical Surface of bushing 5 is provided with some oil grooves 6 for storing lubricating oil, and the second sealing ring 9 is used to hinder
The only anterior oil leakage of universal ball end 3, while be also prevented from foreign object enter between bushing 5 and universal ball end 3, while may be used also
In for static seal and reciprocating motion, universal structure local environment is applicable.The bushing 5 is made of bronze, due to bushing 5
Both extruding force and frictional force, therefore choosing are subjected between fixed shell 2 and universal ball end 3, when in motion process
Select that wearability is good, intensity bronze material high makes bushing 5.
The above, simply better embodiment of the present utility model, but the utility model is not limited to above-mentioned reality
Example is applied, as long as it reaches technique effect of the present utility model with any same or similar means, should all belong to of the present utility model
Protection domain.
