Abstract
The utility model provides a bipyramid sealing mechanism of shafting that solar energy boats and ships were used, it is including the main shaft, main shaft outside cover is equipped with the outer sleeve, the cover is equipped with the inner skleeve between outer sleeve and the main shaft, inside skleeve outer peripheral face tip outwards expands and forms the tip spacing ring, two tip spacing ring relative one side lateral walls go up interior concave formation has the spacing groove, form spacing district between two spacing grooves, inwards shrink formation stopper on the outer sleeve inner chamber wall, the stopper is located spacing district, the stopper tip is equipped with prevents moving the position, prevent moving position and spacing groove gomphosis. The purpose that reduces wearing and tearing can be realized sending out after this scheme of adoption, adopts the bipyramid structure of preventing moving position and spacing groove, makes the inner skleeve be difficult for sliding, and its result of use is better.
Description
Technical Field
The utility model belongs to the technical field of the boats and ships technique and specifically relates to indicate a shafting bipyramid sealing mechanism that solar energy boats and ships were used.
Background
The main shaft in the traditional solar ship shafting is directly sleeved in the outer sleeve, and the main shaft is worn away from the inner wall of the outer sleeve at any time during rotation, so that a gap is easily formed between the outer sleeve and the main shaft, and the service life of the shafting is shortened.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a shafting double-cone sealing mechanism with good use effect for a solar ship.
In order to achieve the above object, the present invention provides a technical solution: a shafting bipyramid sealing mechanism for a solar ship comprises a main shaft, wherein an outer sleeve is sleeved outside the main shaft, an inner sleeve is sleeved between the outer sleeve and the main shaft, the end part of the outer peripheral surface of the inner sleeve is outwards expanded to form an end part limiting ring, limiting grooves are formed in the side walls of the two end part limiting rings on the opposite sides inwards, a limiting area is formed between the two limiting grooves, a limiting block is formed by inwards contracting the inner cavity wall of the outer sleeve and is positioned in the limiting area, and an anti-moving position is arranged at the end part of the limiting block and is embedded with the limiting grooves.
One end of the outer sleeve is expanded outwards to form a connecting ring.
The inner side of the end part of the limiting block gradually extends to form an anti-moving position, and the extending direction of the anti-moving position is consistent with the axial direction of the outer sleeve.
The surface of the end limiting ring is conical, the tip end of the end limiting ring is positioned at the end part of the inner sleeve, and the inner cavity wall of the end part of the inner sleeve is gradually expanded to form a conical expansion cavity.
And the middle part of one side of the inner sleeve is provided with an oil passing hole which penetrates through the inner sleeve and the outer sleeve.
After the above technical scheme is adopted, adopt the extension chamber lubricating oil of being convenient for to get into between main shaft and the inner skleeve from both ends, form spacing district between two spacing grooves, cross the oilhole and make the lubrication by can follow and get into spacing district between inner skleeve and the main shaft, stopper on the outer sleeve inner chamber wall is located spacing district, the main shaft is when rotating, the inner skleeve can follow the rotation (inconsistent with main shaft rotation rate), thereby play the cushioning effect (prevent that the main shaft from rotating and produce the friction between direct and the outer skleeve), realize the mesh that reduces wearing and tearing, adopt the bipyramid structure of anti-dynamic position and spacing groove, make the inner skleeve difficult slip, its result of use is better.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic view of the structure of the limiting groove of the present invention.
Detailed Description
The present invention will be further explained with reference to the drawings, and the preferred embodiment of the present invention is: referring to fig. 1 and 2, the shafting double-cone sealing mechanism for the solar ship comprises a main shaft 6, an outer sleeve 7 is sleeved outside the main shaft 6, an inner sleeve 1 is sleeved between the outer sleeve 7 and the main shaft 6, an oil passing hole 5 which penetrates through the inner sleeve 1 and the outer sleeve is arranged in the middle of one side of the inner sleeve 1, the end part of the outer circumferential surface of the inner sleeve 1 is expanded outwards to form an end part limiting ring 2, the surface of the end part limiting ring 2 is conical, the tip end of the end part limiting ring is located at the end part of the inner sleeve 1, and the inner cavity wall of the end part of the inner sleeve 1 is gradually expanded to form a conical expansion cavity 4. The limiting grooves 3 are formed in the side walls of the two opposite sides of the end limiting rings 2 in an inwards concave mode, a limiting area is formed between the two limiting grooves 3, the inner cavity wall of the outer sleeve 7 is inwards contracted to form a limiting block 8, the limiting block 8 is located in the limiting area, the end portions of the limiting blocks 8 are provided with anti-moving positions, and the anti-moving positions are embedded into the limiting grooves 3. The inner side of the end part of the limiting block 8 gradually extends to form an anti-moving position, the extending direction of the anti-moving position is consistent with the axial direction of the outer sleeve 7, and the end part of one end of the outer sleeve 7 is outwards expanded to form a connecting ring 9.
This embodiment is after adopting above-mentioned scheme, adopt the extension chamber to be convenient for lubricating oil to get into between main shaft and the inner skleeve from both ends, form spacing district between two spacing grooves, cross the oilhole and make the lubrication by can follow the spacing district of getting into between inner skleeve and the main shaft, the stopper on the outer sleeve inner chamber wall is located spacing district, the main shaft is when rotating, the inner skleeve can follow the rotation (inconsistent with main shaft rotation rate), thereby play the cushioning effect (prevent that the main shaft from rotating directly and producing the friction between the outer skleeve), realize the mesh that reduces wearing and tearing, adopt the bipyramid structure of anti-dynamic position and spacing groove, make the inner skleeve be difficult for sliding, its result of use is better.
The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that all the changes made according to the shape and principle of the present invention should be covered within the protection scope of the present invention.
