Abstract
The utility model provides a rail transit car shaft coupling bellows subassembly, the problem that solve is: it does not have the welding point how to realize the connection at bellows both ends, and realizes sealedly. The utility model discloses a main points are: flange, bellows and the internal tooth cover of living connects gradually, and round flange groove alive is opened to its ring flange in flange hole alive, and round internal tooth grooving is opened to the internal tooth cover to the internal tooth trepanning, and the straight -edge section at bellows both ends is two turn -ups all to flanging 90, and in one of them turn -ups inserted round flange groove alive, another turn -ups overlapped sealing washer of installation in bellows and internal tooth inserting round internal tooth grooving. The utility model discloses an actively the effect is: its realizes solderless contact connection between bellows and the flange of living, the internal tooth cover, just will guarantee the leakproofness of bellows subassembly.
Description
Technical field
This utility model is related to a kind of drum-shaped tooth type shaft coupling with sylphon seal, for rail traffic vehicles shaft coupling
Kit-bellows component.
Background technology
High ferro, urban track traffic industry are the industries flourishing in the current or even following quite a long time.
China has become the maximum urban track traffic market in the whole world.Meanwhile, the Transit Equipment that domestic early stage builds also begins to
Face the demand of parts renewal.
The shaft coupling that current track vehicular traffic adopts is the drum-shaped tooth type shaft coupling of different sealing form.Mainly from pellet
Wheat, German and Japanese import.Wherein adopt the shaft coupling application of sylphon seal more, wherein bellows component is by method alive
Orchid, corrugated tube, O-ring seal, internal tooth casing are sequentially connected composition, and shaft coupling corrugated tube one end is connected on internal tooth casing, and the other end leads to
Flange of making a living is connected on external tooth axle.The feature of this shaft coupling is：Barreled tooth flank, driving torque are big, angle compensation and axial position
Move compensation dosage big, using the technology such as bellows structure form and reset, reliability height etc..
Content of the invention
The purpose of this utility model is to provide a kind of supporting bellows component of rail traffic vehicles shaft coupling of solderless contact.
The purpose of this utility model is realized in：Flange alive, corrugated tube and internal tooth casing are sequentially connected, and it is characterized in that：
Flange hole of living opens a circle work flange groove to its ring flange, and a circle internal tooth grooving is opened to internal tooth casing in internal tooth casing hole, corrugated tube two ends
90 ° of the equal outward flanging of straight section, in two flange, one of flange insertion one circle is lived in flange groove, and another flange inserts
In one circle internal tooth grooving, with internal tooth casing, one sealing ring is installed in corrugated tube.
Compared with prior art, good effect of the present utility model is：It is realized corrugated tube and lives between flange, internal tooth casing
Solderless contact connects, and the sealing of bellows component to be ensured.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Specific embodiment
The two ends of corrugated tube 2 are connected with flange 1 of living, internal tooth casing 3 respectively, and attachment structure is：Live flange hole to its ring flange
Open a circle work flange groove 11, a circle internal tooth grooving 31 is opened to internal tooth casing in internal tooth casing hole, and the straight section at corrugated tube two ends is all turned-out
90 ° of side, in a left flange 21 and right flange 22, left flange 21 insertion one circle is lived in flange groove 11, right flange 22 insertion one circle
In internal tooth grooving 31, with internal tooth casing, one sealing ring 4 is installed in corrugated tube.
It realizes corrugated tube solderless contact, and the sealing of bellows component to be ensured.Corrugated tube is because of shaft coupling two ends
Internal tooth casing and external tooth axle move with car body and weight change generation angular displacement and axial displacement, and are in frequent motor process
In.Intracavity between corrugated tube and internal tooth casing equipped with 0.4 liter of lubricating oil, press the cycle and change, therefore corrugated tube adopts monolayer by lubricating oil
Pipe and turnup structure make, and longitudinal seam welding must assure that uniform ground ne-leakage phenomenon, will have good ductility.
