The interior large and middle tractor market demand continues run at high level, but amplification eases up, and demand continues to extend to high-power direction；Little Tuo cities
Field continues persistently to rise with double-digit amplitude, and on the other hand, each region market demand is unbalanced, and brand competition swashs increasingly
Strong, the market concentration further improves, however is far from reaching demand saturation compared with the agriculture developed countries and regions such as America and Europe
Degree, in addition, product structure performance backwardness is China's Tractor Products common problem, technical merit need to be improved,
Since tractor working environment is severe（Sleet, high temperature, humidity etc.）, so it is more demanding for the parts of its composition, such as use
In the sealing shell of tractor gear case assembling, gearbox seals shell is be sealed gear, transmission shaft with the external world one
Design of part is planted, consumption of raw materials is big in traditional gearbox seals shell complexity and production, while easily becomes after being used for a long time
Shape, fracture, this strong influence working efficiency of tractor and there are great security risk.
Therefore, based on the above problem, the utility model provides a kind of sealing shell.
Utility model content
Purpose of utility model：The purpose of this utility model is to provide a kind of sealing shell, reasonable in design, convenient for dress
Match, consumption of raw materials is big in solving the problem of existing gearbox seals shell complexity and producing deformation easily occurs, is broken, and passes through conjunction
The design structure of reason saves raw materials for production, and improves the compactness sealed after assembling, prevents security hidden trouble, is convenient for simultaneously
Installation and demolition and maintenance.
Technical solution：The utility model provides a kind of sealing shell, including sealing shell ontology and is arranged on sealing shell
It the trapezoidal limiting groove of ontology side and is symmetricly set on one group of first positioning hole of sealing shell ontology one end and is arranged on
Second location hole of the sealing shell ontology other end and two groups of limit protrusions being arranged on the upper and lower both sides of sealing shell ontology,
And be arranged on sealing shell ontology on one side and positioned at one group of limit protrusion side positioning wedged block and be arranged on sealing shell ontology
On the first sealing ring, the second sealing ring, third sealing ring and be arranged on sealing shell ontology another side one end limiting it is recessed
Slot and be arranged on the spacing slotted eye being used in combination in sealing shell ontology and with limiting groove and be arranged on the first sealing ring,
The first limiting slot, the second limiting slot between second sealing ring and the one group of third limiting being used in combination with the second sealing ring
Slot.
The technical program, the sealing shell further includes and is arranged on sealing shell ontology on one side above and positioned at one group of limit
First between the protrusion of position assists card slot and is arranged on sealing shell ontology another side and blocks with one group of limit protrusion, positioning
The second auxiliary card slot, third auxiliary card slot between block.
Compared with prior art, a kind of advantageous effect of sealing shell of the utility model is：On the one hand its structure design
Rationally, it convenient for assembling, solves that existing gearbox seals shell is complicated and consumption of raw materials is big in producing, deformation, fracture easily occurs
Problem by rational design structure, saves raw materials for production, and improves the compactness sealed after assembling, prevents security risk and ask
Topic, while be easily installed and demolition and maintenance；On the other hand generally integrally formed agent structure, it is easy to produce to process, be not easy
Deformation and fracture and leakproofness stabilization.
