Abstract
The utility model relates to an all metal plate compounded conical sealing structure, which is mainly designed for solving the problems that contact seal at present has short service life, environmental condition limitation, complex installation, high cost, etc. The utility model adopts the compounded seal of conical plates, the combined force of the elastic force of the conical plates and medium pressure is adopted to act on a seal surface. Even abrasion occurs, a seal body can conduct automatic compensation by the elasticity of the seal body. Thus the utility model has the advantages of long service life, convenient installation, good seal effect and compact structure. The utility model can be used for lubricating occasions and non-lubricating occasions. The utility model can be widely used for the seal of rotating and reciprocating moving components.
Description
The utility model relates to a kind of sealing configuration that is used to rotate with reciprocating part, particularly a kind of full-metallic sheet composite conic sealing configuration.
The motive sealing of moving element and relative static part can be divided into contact seal and noncontact seal, and contact seal divides four kinds of packing seal, expansion ring seale, cup packing and mechanical seals again.There is following shortcoming respectively in these four kinds of sealings owing to be subjected to condition restriction such as intrinsic structure, form, material:
1, gland sealed shortcoming: its sealing effect is directly proportional with the extruding force of filler to axle.Therefore the junction plane of filler and axle is because friction and heat production, has that power consumpiton is big, filler wearing and tearing, aging speed is fast, working life is low shortcoming.
2, the shortcoming of expansion ring seale: expansion ring seale must use in lubricated medium is arranged, and packing jointing processing difficulties is not suitable for being extensive use of.
3, the shortcoming of cup packing: the material that leather cup uses mostly is non-metallic elastic materials such as rubber, leather, plastics, and it is bigger that the life-span of leather cup is influenced by temperature, pressure and speed, the occasion that incompatibility high temperature, high pressure and speed are higher.
4, the shortcoming of mechanical seal: the mechanical seal structure complexity, it is big to take up room, the installation requirement strictness, cost is higher.
The purpose of this utility model is to overcome the shortcoming of above-mentioned sealing, make its have compact structure, volume little, be easy to install, good sealing effect, long service life, the material selection scope is big, cost is low advantage; Simultaneously, the sealing structure can also have lubrication concurrently.
For achieving the above object, the technological scheme that the utility model adopted is:
Be superimposed to form the taper sealing by two or two above cone sheets, wherein measure-alike, the end circle of each cone sheets tip circle is measure-alike, and cone sheets is along tip circle even distribution otch downwards.Be inserted in making a concerted effort of pressure that elasticity clamping force that axle back produces and medium act on sealing surface by cone sheets, it is tight that sealing surface is combined with axle, thereby reach the purpose of sealing.
The purpose of this utility model also can reach by following measure:
Have oil hole on the cone sheets.
The purpose of this utility model can also reach by following measure:
Have oil hole on the cone sheets, and oil hole communicates with radial incision.
The purpose of this utility model can also reach by following measure:
The cone sheets that stack combinations is selected, the incision site of sheet and sheet is interlaced arranges.
Owing to adopted technique scheme, it is low that the utility model has consumed power than the conventional seals structure, and good sealing effect is difficult for the sealing that advantage such as aging is made up of the utility model and anti-wear sleeve, and its surface friction drag is much smaller than conventional seals.Even wear and tear, seal also can compensate automatically by the elasticity of self, and this compensation can guarantee sealing effect, can increase working life again.In addition,, can use by oil injecting lubricating by the combination of different cone sheets, again can non-lubricated use.
Below in conjunction with accompanying drawing the utility model being done one describes in detail:
Fig. 1 is the structural representation of cone sheets compound sealing structure;
Fig. 2 is a lubricating type cone sheets compound sealing structure;
Fig. 3 is non-lubricating type awl film compound sealing structure.
As shown in Figure 1, cone sheets can have several forms: a kind of is that tip circle along cone sheets evenly has radial incision 1 downwards; Second kind is except that radial incision is arranged, and also has oil hole 2, but oil hole does not communicate with otch; The third is that oil hole communicates with otch.Is the distribution viewpoint definition of the circle size in the cone sheets and the radial incision in one week of interior circle that evenly distributes inside dimension; Mounting hole, oil hole, the end circle size of cone sheets, be referred to as outside dimension near cylindrical.
In Fig. 1, be used for the cone sheets compound sealing structure of lubrication state, need select the combination of odd number sheet inside dimension is identical, outside dimension is also identical cone sheets for use, the cone sheets that oil hole and otch are not communicated is called top flat 3 as seal cone top part diaphragm seal; The cone sheets that oil hole is communicated with otch is as oil transportation sheet 4; If several oil transportation sheets are arranged, can also add spacer 5 between the oil transportation sheet, the structure of spacer is identical with top flat; And the cone sheets that will not have oil hole is called egative film 6 as seal awl bottom diaphragm seal.As shown in Figure 2, make the diameter of the tip circle of the taper that is formed by stacking by cone sheets, thereby be inserted in axle back generation elasticity clamping force less than axle, add the pressure of medium, make the taper cone top part produce clamping force to axle sleeve, the otch of every cone sheets of seal is interlaced arranges, to seal otch.The lubricated of seal is to realize by the oil transportation sheet between oil hole 7 and top flat and the egative film, and promptly lubricant oil enters the junction plane 8 of taper top and axle, lubricate by oil hole 7 along the oil transportation otch of oil transportation sheet.For guaranteeing sealing effect, the cone sheets of selecting for use as a seal can be integral through electric welding, riveting or machining.
In Fig. 3, be used for the cone sheets compound sealing structure of non-lubrication state, the number of cone sheets can be chosen wantonly, and egative film, spacer, top flat do not have strict restriction yet.
