Description
Technical field
The utility model is related to a kind of sealing device, and especially a kind of tractor end that is arranged on is driven upper and sealing effectiveness
Good sealing device, belongs to seal technical field.
Background technology
In existing wheeled tractor forerunner final drive assembly, to prevent oil leak at drive shaft, two skeletons are employed
The sealing means that oil sealing, bushing and a sealing ring are combined, while being employed in stub shell and drive housing junction dust-proof
The sealing structure that circle, bushing, support set and sealing ring combine is sealed.Above two sealing structure is in assembling process
Because parts are more, not only efficiency of assembling is low, and causes processing accumulated error big due to crossing multiple component combination, works as drive
When moving axis or stub shell have deviation from circular from, concentricity or vibration, the relative position between each parts easily becomes
Change, ultimately result at drive shaft or stub shell that sealing effectiveness is not good, easily occur oil leakage phenomenon, so as to influence complete machine usability
Energy.Further, since outside framework oil seal is high to the required precision of drive shaft finished surface, it is necessary to which its surface essence could be met by being ground drive shaft
Degree is required, virtually improves cost.
Utility model content
The purpose of this utility model is to provide that a kind of simple in construction, efficiency of assembling is high, good sealing effect tractor end
Transmission seal device.
The utility model is achieved by the following technical programs：
A kind of tractor end transmission seal device, including Driving terminal, drive shaft, drive housing, stub and stub shell；
On Driving terminal is fixed on the outside of drive housing, drive shaft two ends are respectively supported in Driving terminal and drive housing by bearing
Interior, drive shaft flange is connected with Driving terminal；Stub lower end termination is connected through stub shell lower end with bevel gear, under stub shell
End is supported on drive housing lower end by bearing；Between the drive shaft and Driving terminal endoporus and stub shell lower end is with passing
Combination oil seal is respectively equipped between dynamic housing lower end endoporus, the combination oil seal includes inner oil seal, inner frame, outer oil seal and dermoskeleton
Frame, inner oil seal is interference fitted with drive shaft and stub shell lower end respectively, and inner frame is sleeved on inner oil seal, and outer oil seal fixes suit
On inner frame periphery, outer skeleton one end is ridden against in inner oil seal outer rim, and the outer skeleton other end is inlaid in interior on the outside of outer oil seal.
The purpose of this utility model can also further be realized by following technical measures.
Foregoing tractor end transmission seal device, wherein described inner oil seal is identical with inner frame shape.
Foregoing tractor end transmission seal device, wherein extending multiple sealing lips on described outer oil seal.
Foregoing tractor end transmission seal device, wherein described multiple sealing lips are respectively embedded into inner frame.
Foregoing tractor end transmission seal device, wherein sheathed spring on described outer oil seal inner side periphery.
The utility model eliminates the former sealing structure of tractor end transmission, and is adopted respectively at its drive shaft and stub shell
Sealed with a combination oil seal, simple in construction, good sealing effect.Because parts are few, efficiency of assembling is not only increased,
And because parts machining link accumulated error is small, it is easy to ensure the relative position between each parts during use, from
And sealing effectiveness is ensure that, complete machine is not susceptible to oil leakage phenomenon, improves complete machine performance.Further, since combination oil seal with
It is interference fit between drive shaft, so only needs turning drive shaft just can meet its surface finish requirements, greatly reduce processing
Cost.Seal can be stabilized in mounting hole by the outer skeleton of combination oil seal and outer oil seal, it is ensured that seal installs reliable and stable,
Its inner frame and inner oil seal can ensure that sealability, reduce the failure caused by oil leak, reduce tractor end transmission
Maintenance frequency, and simple installation, further increase efficiency of assembling.Extend multiple sealing lips, and multiple sealings on outer oil seal
In lip insertion inner frame, it can effectively prevent rainwater and dust from entering in drive housing, so as to extend each parts in drive housing
Service life.
Advantage and feature of the present utility model, will carry out diagram reconciliation by the non-limitative illustration of preferred embodiment below
Release, these embodiments, only provide as an example referring to the drawings.
