Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
The present invention provides sealing structure after a kind of outer cylinder, and as shown in figures 1-8, which includes being arranged in tripod 10
On ring packing muscle 1, the annular seal groove 2 on 20 after outer cylinder, and the sealing ring 3 in annular seal groove 2 are set,
Above-mentioned ring packing muscle 1 is inserted into annular seal groove 2 and compresses sealing ring 3.By sealing structure after above-mentioned outer cylinder, cooperation is existing
Some 30 structures of oil sealing, can be realized the dual-seal to main shaft 40, further improve sealing effect, while can be to triangle
The central area of frame 10 seals, and avoids its central area by corrosion and damage.In the present embodiment, above-mentioned sealing ring 3 is spherical close
Seal.
As depicted in figs. 1 and 2,20 after above-mentioned tripod 10 and outer cylinder between be equipped with oil sealing 30 and bearing 50, above-mentioned oil sealing
30 and bearing 50 be set on main shaft 40, wherein oil sealing 30 can by the clearance seal between after main shaft 40 and outer cylinder 20, and
The oil sealing 30 is placed in the sealing space that ring packing muscle 1 and annular seal groove 2 are formed.By the way that oil sealing 30 is placed in ring packing
In the sealing space that muscle 1 and annular seal groove 2 are formed, can after the outer cylinder through this embodiment sealing structure by oil sealing 30
In being sealed in, the dual-seal to main shaft 40 is realized, the service life of main shaft 40 is effectively improved.
In the present embodiment, as shown in figure 4, the end of 10 central area of tripod is arranged in above-mentioned ring packing muscle 1, specifically
, the through-hole (not shown) for loading main shaft 40 is provided in the central area of tripod 10, above-mentioned 1 ring of ring packing muscle is located at
On the outside of the through-hole.In order to which region, through-hole and the main shaft 40 to 1 inside of ring packing muscle are sealed protection, prevent from washing
It washs line bits and enters 10 center of tripod to its corrosive wear.
Further, it can refer to Fig. 3, the end surface that above-mentioned ring packing muscle 1 is inserted into the annular seal groove 2 is ball
Face enables to ring packing muscle 1 to be more easily inserted in annular seal groove 2 by the setting of spherical structure, convenient for dress
Match, and can preferably realize and be contacted with spherical sealed circle 3, increases the stability of its contact squeeze, avoid sealing not in place.
As viewed in figures 5-8, above-mentioned annular seal groove 2 is provided with after outer cylinder in 20 one sides opposite with tripod 10, and should
2 ring of annular seal groove is located at after outer cylinder 20 spindle mounting hole (not shown) outside.It can refer to Fig. 8, in annular seal groove 2
It is interior to be equipped with the protrusion 4 for being directed toward ring packing muscle 1, specifically, the protrusion 4 is that ring is located at the convex annular in the annular seal groove 2
Structure is played, and sealing ring 3 is squeezed and compressed by the protrusion 4 and the cooperation of ring packing muscle 1.By the way that the protrusion 4 is arranged, this can be reinforced
The sealing effect of sealing structure after outer cylinder.
In order to further strengthen the sealing performance of sealing structure after outer cylinder, in the present embodiment, above-mentioned annular protrusion structure with
The contact surface of sealing ring 3 is located at the middle position of sealing ring 3.
It should be pointed out that above-mentioned raised 4 thickness should not be too large, lead to 1 nothing of ring packing muscle to avoid thickness is excessive
The depth that method is inserted into annular seal groove 2 or in insertion annular seal groove 2 is excessively shallow, influences sealing effect.In the present embodiment, on
State protrusion 4 thickness no more than annular seal groove 2 depth half.
The present invention is by sealing structure after above-mentioned outer cylinder, when assembling main shaft 40, can pass through the annular on tripod 10
Sealing bar 1 is inserted into annular seal groove 2 and compresses sealing ring 3, can be avoided washing line bits and dust and other impurities enter oil
