Abstract
A kind of Novel flexible Special seal set, its outer formation is cylindrical, inside is shoulder hole structure, stepped hole side is the bracing wire hole of minor diameter, and the other side is the housing pore of major diameter, and the inner opposite end of housing pore is provided with semicircular fixing groove, it is evenly arranged with sealing ring on the bracing wire hole hole wall of stepped hole, at isosceles trapezoid or semicircle, the inside diameter of sealing ring is less than the bowden cable tip diameter being connected in the section of sealing ring, and the diameter in bracing wire hole is more than bowden cable end outside diameter；By the implementation of the utility model, good using effect is reached：Novel flexible Special seal covers through the sealing ring in endoporus the water inlet being effectively prevented inside flexible axle to the sealing inside flexible axle and into dust, avoids the unexpected failure of flexible axle, effectively raises the stability of engineering machinery, improve the performance of complete machine.
Description
Technical field
The utility model is related to flexible axle fields, relate generally to a kind of Novel flexible Special seal set.
Background technology
With domestic manufacturing horizontal continuous improvement, there are higher requirement, especially engineering machinery to product quality
For product also from being exactly that stupid big stupid thick type is changed toward small and exquisite fine type in the past, flexible axle is right as the necessary accessory of engineering machinery
The requirement of technology is also constantly being promoted, and since engineer machinery operation environment is all relatively more severe, flexible axle is as transmission power in a kind of dress
It sets, is mainly made of bracing wire and outer tube, it is poorly sealed due to the end of outer tube and bracing wire end in use, lead to housing
Inside pipe between bracing wire water inlet, into dust, result in abrasion between bowden cable and outer tube over time and get rusty and dust
It stagnates, simultaneously because inside needs that lubricating grease is added, dust is also easy to cause the rotten of lubricating grease, finally makes bowden cable outside
Clamping stagnation, failure in casing are even broken, and make engineering machinery that can not work, or even cause a serious accident；Therefore, it is necessary to a kind of new
The sealing device of shape solves the problems, such as water inlet in existing flexible axle, causes bowden cable clamping stagnation, failure in outer tube into dust.
Invention content
The utility model proposes a kind of Novel flexible Special seal set, for solving existing flexible axle water inlet, into ash
Dirt causes bowden cable in outer tube the problem of clamping stagnation, failure.
In order to realize the purpose of utility model, the utility model adopts the following technical solution：
A kind of Novel flexible Special seal set, outer to form cylinder, inside is shoulder hole structure, and stepped hole side is small
The bracing wire hole of diameter, the other side are the housing pore of major diameter, and the inner opposite end of housing pore is provided with semicircular fixing groove,
Be evenly arranged with sealing ring on the bracing wire hole hole wall of stepped hole, the section of sealing ring at isosceles trapezoid or semicircle, sealing ring
Inside diameter is less than the bowden cable tip diameter being connected, and the diameter in bracing wire hole is more than bowden cable end outside diameter；
Housing pore and the end outer circle of flexible shaft jacket pipe are interference fitted, the appearance and size and flexible shaft jacket of the fixing groove in housing pore
The end appearance and size of pipe is consistent.
The sealing ring is arranged for parallel equidistant, sealing ring at least two.
It is provided with chamfering in the Novel flexible Special seal set bracing wire hole side outer circle.
By the implementation of the utility model, good using effect is reached：Novel flexible Special seal set passes through endoporus
In sealing ring to the sealing inside flexible axle, the water inlet that has been effectively prevented inside flexible axle and into dust avoids the meaning of flexible axle
Outer failure effectively raises the stability of engineering machinery, improves the performance of complete machine.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
In figure：1, sealing ring, 2, bracing wire hole, 3, fixing groove, 4, housing pore, 5, outer tube, 6, bracing wire.
Specific implementation mode
The utility model specific embodiment is described with reference to the drawings：
A kind of Novel flexible Special seal set as shown in Figure 1, entirety are made of ethylene propylene diene monomer (EPDM) material, ternary second
Third rubber can effectively improve wearability and reduce frictional force, and the outer formation of Novel flexible Special seal set is cylindrical, outer circle
Left end is provided with chamfering, flexible axle can be made to be easier to be oriented to installation when installation, inside is shoulder hole structure, and stepped hole falls
Angle side is the bracing wire hole 2 of minor diameter, and the other side is the housing pore 4 of major diameter, and the inner opposite end of housing pore 4 is provided with half
Circular fixing groove 3 is evenly arranged with sealing ring 1 on 2 hole wall of bracing wire hole of stepped hole, and the section of sealing ring 1 is at isosceles trapezoid
Or it is semicircle, the inside diameter of sealing ring 1 is less than 6 tip diameter of bowden cable being connected, and sealing ring 1 sets for parallel equidistant
It sets, sealing ring 1 at least two；The diameter in bracing wire hole 2 is more than 6 end outside diameter of bowden cable；Outside housing pore 4 and flexible axle
The end outer circle of casing 5 is interference fitted, the end shape of the appearance and size and flexible shaft jacket pipe 5 of the fixing groove 3 in housing pore 4
Size is consistent.
When in use, first the housing pore 4 of Novel flexible Special seal set to the end of positive flexible shaft jacket pipe 5,
6 end of bracing wire is penetrated from the bracing wire hole 2 in left side, so that 6 end outer circle of bracing wire is contacted with the sealing ring 1 in bracing wire hole 2, and housing
Pore 4 is connected with 5 end outer circle of outer tube, and 5 end face of outer tube is contacted with the left side in housing pore 4, makes fixing groove 3
It is connect with 5 left end form fit of outer tube, just completes the installation process of Novel flexible Special seal set later.
The non-detailed portion of the utility model is the prior art.
