Abstract
The utility model discloses a kind of seal cartridge, including bush body, the outer circle of the bush body is formed with the outer circle section with oil sealing cooperation, and the annular groove for installing sealing ring is formed on the inside of the bush body.The outer circle section high-frequency quenching.Chamfering at one end outer circle of the bush body, the guide frame being oriented to when being formed for installing oil sealing.Using utility model device, the static sealing being not only able to satisfy between output shaft, but also the dynamic sealing being able to satisfy between extension box, moreover it is possible to it solves to reprocess the part of Rear Derailleur tail portion oil leakage problem.
Description
Technical field
The utility model relates to mechanical seal assembly technical fields, and in particular to a kind of for the close of speed changer tail portion sealing
Seal bushing.
Background technique
An important components of the speed changer as automobile, for the bushing with speed changer tail portion, outer circle and extension box
Cooperation, internal to cooperate with output shaft, sealing problem is extremely important, and existing seal with buss performance is bad, and not being able to satisfy production needs
It wants.
Utility model content
In view of this, being both able to satisfy between output shaft the purpose of this utility model is to provide a kind of seal cartridge
Static sealing, and it is able to satisfy the dynamic sealing between extension box, moreover it is possible to solution reprocesses the zero of Rear Derailleur tail portion oil leakage problem
Part.
A kind of seal cartridge of the utility model, including bush body, the outer circle of the bush body is formed with matches with oil sealing
The outer circle section of conjunction is formed with the annular groove for installing sealing ring on the inside of the bush body.
Further, the outer surface of the outer circle section is 0.5-2.5mm by quenching treatment, the depth of quenching.
Further, chamfering at one end outer circle of the bush body, the guiding being oriented to when being formed for installing oil sealing
Structure.
Further, the identification structure for preventing misloading is provided in the bush body.
Further, the identification structure is the mistake proofing step that the bush body other end is arranged in.
Further, the mistake proofing step is the ring-shaped step that bush body removes that surface is formed.
Further, the ring-shaped step extends from the end face of seal body to the other end.
Further, the outer circle section is located at the middle section of bush body.
Further, the outer diameter of the outer circle section is greater than the outer diameter of the ring-shaped step.
Further, the annular groove is located in the inner circle section of bush body corresponding to ring-shaped step.
The utility model has the beneficial effects that the static state being both able to satisfy between output shaft is close using utility model device
Envelope, and it is able to satisfy the dynamic sealing between extension box, moreover it is possible to it solves to reprocess the part of Rear Derailleur tail portion oil leakage problem.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model seal cartridge；
Fig. 2 is the assembling schematic diagram of the utility model seal cartridge.
Specific embodiment
Fig. 1 is the structural schematic diagram of the utility model seal cartridge, and Fig. 2 is that the assembly of the utility model seal cartridge is illustrated
Figure.A kind of seal cartridge of the utility model, including bush body 1, the outer circle of the bush body 1 are formed with and oil sealing cooperation
Outer circle section 2, the inside of the bush body 1 are formed with the annular groove 3 for installing sealing ring.Using utility model device, both
The static sealing being able to satisfy between output shaft 6, and the dynamic sealing being able to satisfy between extension box 7, by being provided with and oil
The outer circle section 2 for sealing cooperation is interference fitted with oil sealing, moreover it is possible to solve to reprocess the part of Rear Derailleur tail portion oil leakage problem.
In the present embodiment, by quenching treatment, the depth of quenching is 0.5-2.5mm for the outer surface of the outer circle section 2.It is logical
It crosses the position high-frequency quenching of bush body 1 and oil sealing cooperation, to increase matching surface wearability, that improves bushing uses the longevity
Life.
In the present embodiment, chamfering at one end outer circle of the bush body 1 is oriented to when being formed for installing oil sealing
Guide frame 4 facilitates the installation of oil sealing.
In the present embodiment, it is provided with the identification structure for preventing misloading in the bush body 1, installation can be improved
Efficiency prevents worker's misloading.
In the present embodiment, the identification structure is the mistake proofing step that 1 other end of bush body is arranged in, and mistake proofing step is more square
Just it processes, it is high in machining efficiency, the function of bush body 1 is not influenced.
In the present embodiment, the mistake proofing step be bush body 1 remove surface formed ring-shaped step 5, ring-shaped step 5 from
The end face of bush body 1 extends to the middle part of bush body 1, and processing is more convenient, and cost is lower, facilitates the identification of worker.
In the present embodiment, the outer circle section 2 is located at the middle section of bush body 1, assembles more stable.
In the present embodiment, the outer diameter of the outer circle section 2 is greater than the outer diameter of the ring-shaped step 5, and assembly is stablized, due to outer circle
Section 2 is located at the middle section of bush body 1, and the intensity of bush body 1 is higher, and readily identified.
In the present embodiment, the annular groove 3 is located in the inner circle section of bush body 1 corresponding to ring-shaped step 5.What this place was stated
Inner circle section corresponding to ring-shaped step 5, refers to the inner ring fragment position in the radial corresponding bush body 1 of ring-shaped step 5, and use is such
Setting, sealing effect are more preferable.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
