Description
Technical field
The invention belongs to gearbox technical fields, and in particular to a kind of hydraulic transmission box.
Background technology
The oil suction mechanism of hydraulic transmission box oil pump is built in box house mostly, and oil pump sucks particulate matter in order to prevent, inhales
Contain filter in oil machine structure, and filter is consumable articles, after a period of time, the pore of filter will be blocked up by particulate matter
Plug, then need replacing new filter；And for the oil suction mechanism for being built in case type, needing to dismantle shell could replace
Filter core, it is very time-consuming and laborious.Furthermore, it is contemplated that the casting and processing etc. of shell, the oil suction road diameter being placed in transmission housing body
It is smaller, and at right angles turning mostly, it also will produce many idle blind oilholes and be connected with main oil gallery, seal there is also risk,
Oil pump is easily set to generate air pocket, output oil amount is unstable；And flow and pressure fluctuation are also resulted in, vibration and noise is generated；Because wanting
Oilhole is processed on shell, the iron filings in oilhole are difficult to be cleaned, and accelerate the blocking of filter；Secondly to the shrinkage porosite of casting
It is required that higher, if pipeline passes through shrinkage porosite point, oil pump is difficult to be drawn onto fluid, and entire shell cannot use.
Invention content
In order to overcome the shortcomings of the prior art, the present invention provides a kind of hydraulic transmission box, installation and removal are easy
Fast, oilhole need not be processed in shell, avoids that oil duct diameter is small and the defect of right-angled bend, also simplify shell plus
Work and casting.
For achieving the above object, present invention employs following technical solutions：
A kind of hydraulic transmission box, including gear box casing and oil suction mechanism, the oil suction mechanism include being embedded in gear box casing
Internal filter outer barrel, strainer cover is installed on the gear box casing on filter outer barrel top；The strainer cover
It is connect with the filter set on filter outer barrel by stud；The bottom end of the filter outer barrel is connect with fuel sucking pipe.
The top outer edge of further scheme, the filter outer barrel is equipped with a circle boss, the top of the filter outer barrel
Outer barrel chamfering is equipped between end face and boss；Opened up on the gear box casing being in contact with filter outer barrel top exterior walls with it is described
The matched locating slot of boss, between the top end face and locating slot of the gear box casing be equipped with shell chamfering, by outer barrel chamfering,
Shell chamfering and the annular groove that strainer cover Formation cross-section is triangle.
Further scheme is arranged with large sealing packing ring in the annular groove.
Further scheme is equipped with small sealing ring between the strainer cover and filter；The bottom end of the filter outer barrel
Equipped with connecting pin, the connecting pin and fuel sucking pipe junction are conical surface seal, and the junction of connecting pin and fuel sucking pipe passes through connection
Nut is fixed.
The top of further scheme, the stud is connect with strainer cover, and the bottom end of stud passes through after filter by tight
Gu nut is fixed.
Further scheme offers bolt hole on the gear box casing, and the strainer cover is installed by installation bolt
In the top end face of gear box casing.
Filter outer barrel is sleeved on by its boss in the locating slot on gear box casing in the present invention, and generates axial limit
Position；The connecting pin on filter outer barrel is fixedly connected with fuel sucking pipe by attaching nut again, due to connecting pin and oil suction
The sealing means of pipe junction are conical surface seal, can prevent from being emptied；And the end of fuel sucking pipe is stretched into fluid, it is ensured that oil suction.So
The filter with Stud connection is built in filter outer barrel afterwards, then strainer cover is threadedly coupled with stud；Finally
Strainer cover is fixedly mounted on gear box casing by installation bolt, then outer barrel chamfering, shell chamfering and strainer cover three
Formation cross-section is the annular groove of triangle between person, and upper large sealing packing ring is then arranged in annular groove and is sealed, to prevent
Fluid is leaked out from gear box casing.
The present invention is arranged with small sealing ring between strainer cover and filter, is filtered in order to prevent fluid quilt
Sucking.
Since filter outer barrel is sleeved on by its boss in the locating slot on gear box casing, and generate axial limiting；From
And when needing to change filter, installation bolt can be directly removed, the filter then removed strainer cover and be connected thereto, then
It replaces filter to reinstall again, dismounting, installation operation are convenient.
The advantageous effects of the present invention embody in the following areas：
1, the oil suction mechanism in the present invention uses partial installation formula, detachable by filter outer barrel, strainer cover and filter
Formula forms, to facilitate the installation and replacement of filter；It can avoid dismantling gear box casing when replacing filter, directly take
Lower strainer cover, you can it replaces, it is easy to operate.
2, oil suction mechanism is mounted on gear box casing in the present invention, without the processing oil duct inside gear box casing
The wall thickness of shell can be cast uniform, reduction casting flaw, and reduce the possibility for the defects of casting generates shrinkage porosite by hole,
Improve qualification rate；Improve the casting manufacturability of gear box casing.
3, the connecting pin in the present apparatus on filter outer barrel is fixedly connected with fuel sucking pipe by attaching nut, is avoided
Gear box casing inside machining diameters are smaller and the oil hole of right-angled bend, and are formed because of processing oil duct hole many idle
Blind oilhole, avoiding generating makes oil pump generate the defect that air pocket and hole wall generate cavitation erosion, also avoids shell internal oil channel hole because of iron filings
Cleaning accelerates filter restriction etc. not to the utmost.The stability for also improving oil pump output oil amount simultaneously, advantageously reduces vibration and noise.
4, Formation cross-section is the ring of triangle between filter outer barrel, gear box casing and strainer cover three in the present invention
Then shape slot is arranged upper large sealing packing ring in annular groove and is sealed, to prevent fluid from being leaked out from gear box casing.I.e. originally
Sealing structure performance is good, reduces the risk of permeability.
5, the machine oil suction tube wall is clean, free from admixture, is conducive to raising filter and uses duration.
