Abstract
The utility model discloses an oiling cover structure of a decelerator. The structure includes an oiling cover and an oiling pipe, a pipe-shaped elastic gasket is arranged on the inner wall at the opening of the oiling pipe, internal threads are arranged on the inner wall surface of the pipe-shaped elastic gasket, the inner opening edge of the pipe-shaped elastic gasket is in a flaring structure, an elastic plug body is arranged on the inner surface of the oiling cover, external threads matched with the internal threads are arranged on the outer peripheral surface of the elastic plug body, and the oiling cover and the oiling pipe are in a on-off assembling manner through the threaded cooperation of the elastic plug body and the elastic gasket. The loosening phenomenon of the oiling cover due to the high-speed running of the decelerator is fundamentally eliminated, therefore, the structure better prevents the lubricating oil in the decelerator from leakage, reduces the consumption of the lubricating oil in the decelerator, and improves the safety and reliability of the running of the decelerator, furthermore, the structure has good social and economic valves as well as is easy in popularization and application.
Description
Technical field
The utility model relates to retarder, is specifically related to a kind of structure of retarder fuel door.
Background technique
Retarder is the critical component in the mechanical transmission; In the machinery of many high speed operations, can produce bigger vibration, vibration can cause the loosening of some sealing positions; Thereby have influence on the proper functioning of retarder; Can cause the leakage of lubricant oil like getting loose of fuel door, not only waste oil plant, and existed very big potential safety hazard.
The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, and a kind of structure that can effectively eliminate the retarder fuel door that fuel door gets loose is provided.
For realizing above-mentioned purpose, the technological scheme of the utility model is a kind of retarder fuel door structure of design, and said structure comprises fuel door; Oil filling pipe; It is characterized in that the mouth of pipe place inwall of said oil filling pipe is provided with the tubular resilient liner, the internal face of said tubular resilient liner is provided with internal thread; The internal orifice of said tubular resilient liner is along locating to be the enlarging structure; Internal surface in said fuel door is provided with the elasticity cock body, is provided with the outside thread with described screw-internal thread fit at the outer circumferential face of said elasticity cock body, is assembled together through the screw-thread fit between elasticity cock body and the elastic insert is able to turn on or off between said fuel door and the said oil filling pipe.
Wherein optimized technical scheme is, is provided with a pair of sealing pair structure at the mouth of pipe place of tubular resilient liner and the corresponding position of elasticity cock body between described tubular resilient liner and the elasticity cock body.
Further optimized technical scheme, described a pair of sealing pair structure is by the conical surface/conical surface, the conical surface/arc convex and arc-shaped concave/cone structure that be provided with and corresponding position elasticity cock body root setting constitute along the place in the said tubular resilient pad openings.
Further optimized technical scheme, the inside of described elasticity cock body is the rectangular cavity structure, and the inside of rectangular cavity structure coincide and is installed with side's plate, and said side's plate is fixed together through lid arbor and fuel door.
Further optimized technical scheme, described tubular resilient liner and elasticity cock body are processed by rubber, and both are equipped with the outer of corresponding matching and turn edge.
Further optimized technical scheme, described tubular resilient liner and oil filling pipe inwall bond together, and described elasticity lining body and fuel door bond together.
The advantage and the beneficial effect of the utility model are: because in this retarder fuel door structure; Be assembled together through the screw-thread fit between elasticity cock body and the elastic insert is able to turn on or off between fuel door and the oil filling pipe; Sticking each other mill together between elasticity cock body and the elastic insert; Play good stopping effect, avoided getting loose of fuel door; In addition, the sealing pair structure that is provided with in the corresponding position of the mouth of pipe place of tubular resilient liner and elasticity cock body between tubular resilient liner and the elasticity cock body has also guaranteed the stability that combines between fuel door and the oil filling pipe to have the stopping effect well.During use, fuel door is covered on oil filling pipe the rotation fuel door; Can have good stopping effect with fuel door and oil filling pipe close fit together, fundamentally eliminate the phenomenon that the fuel door brought because of the speed reducer high speed operation gets loose; Prevent the leakage of lubricant oil in the retarder well, reduced the consumption of lubricant oil in the retarder, improved the safety reliability of retarder operation; Favorable social and economic value are arranged, be easy to apply.
Description of drawings
Fig. 1 is the structural representation of the utility model retarder fuel door.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
As shown in Figure 1; The utility model is a kind of retarder fuel door structure, comprises fuel door 3, oil filling pipe 4; Oil filling pipe 4 mouth of pipe place inwalls are provided with tubular resilient liner 1; Tubular resilient liner 1 internal face is provided with internal thread, and the internal orifice of tubular resilient liner 1 is along locating to be the enlarging structure, is provided with elasticity cock body 2 at the internal surface of fuel door 3; Be provided with the outside thread with described screw-internal thread fit at the outer circumferential face of elasticity cock body 2, between fuel door 3 and the oil filling pipe 4 through able to turn on or off being assembled together of screw-thread fit between elasticity cock body 2 and the elastic insert 1.Tubular resilient liner 1 bonds together with oil filling pipe 4 inwalls; Elasticity lining body 2 bonds together with fuel door 3; Be provided with a pair of sealing pair structure at the mouth of pipe place of tubular resilient liner 1 and the corresponding position of elasticity cock body 2 between tubular resilient liner 1 and the elasticity cock body 2, wherein the sealing pair structure is made up of the cone structure 6 of cone structure 5 that is provided with along the place in tubular resilient liner 1 opening and corresponding position elasticity cock body 2 root settings.The inside of elasticity cock body 2 is the rectangular cavity structure, and coincideing in the inside of rectangular cavity structure is installed with side's plate 7, and square plate 7 is fixed together with fuel door 3 through lid arbor 8, can play the effect that the rotating force on the lid arbor 8 is passed to elasticity cock body 2.Tubular resilient liner 1 and elasticity cock body 2 are processed by rubber, and both are equipped with the outer of corresponding matching and turn edge 9 and 10.
Sealing pair structure in the present embodiment also can constitute for the conical surface/arc convex and the arc-shaped concave/cone structure that is provided with along the place in tubular resilient liner 1 opening and corresponding position elasticity cock body 2 roots are provided with.
