Description
Technical field
A kind of float grease seal is the utility model is related to, belongs to machinery field.
Background technology
Float grease seal is a kind of mechanical seal of special shape, and also known as Double-conical-surface oil sealing, mechanical end face seal, double-curved surface are close
Envelope or permanent seal.The most common form of float grease seal has DO types and DF type float grease seals, and metal floating ring axial cross section is in horse
Saddle type, supporting O types rubber seal, the float grease seal price of foreign brand name is high, domestic since material and machining accuracy are unqualified
Cause of poor quality.In addition the float grease seal of standard is not suitable for the operating mode of horizontal decanter centrifuge.So, it is now desired to according to reality
Border needs to develop a kind of new float grease seal suitable for horizontal decanter centrifuge.
Utility model content
The purpose of this utility model is that：In view of the above-mentioned problems, provide a kind of reasonable in design, highly reliable, sealing
Performance is good and the float grease seal of service life length.
In order to reach object above, the technical solution of the utility model is as follows：A kind of float grease seal, including a pair of mutually patch
The floating seat of conjunction and a pair of sealing ring being bonded to each other in corresponding floating seat, it is characterised in that：Outside the sealing ring
Footpath is pyramidal structure；Inside the floating seat taper groove is set to the pyramidal structure corresponding position；The pyramidal structure and taper
Gap is provided with elastic sealing element between groove.
The technical solution that the utility model further limits as：Notch is equipped with the inside of taper groove inside floating seat,
Gap is provided with O-ring seals between the notch and sealing ring.
Further, the taper of the taper groove is 20 °.
Further, the taper of the pyramidal structure is 15 °.
Further, the gap between described two floating seats is 3mm ~ 5mm.
Further, described two sealing ring phase veneers form V-shaped gap structure, and the taper of the V-shaped gap structure is
10°。
Further, the elastic sealing element is 0 shape sealing ring.
The beneficial effects of the utility model：The utility model structure design advantages of simple and good seal performance, can effectively prevent
Only exterior foul, damage bearing.The utility model is easily installed, cost-effective, service life length, from the inclined of Centering compensation axis
The heart misaligns, and reliability greatly improves.
Brief description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, wherein：
Fig. 1 is the structure diagram of the utility model.
Embodiment
Embodiment one
A kind of float grease seal that the present embodiment provides, as shown in Figure 1, floating seat 1-1,1-2 for being bonded to each other including a pair
Sealing ring 2-1,2-2 in corresponding floating seat are bonded to each other with a pair, the outside diameter of the sealing ring is pyramidal structure 5；
Inside the floating seat taper groove 6 is set to 5 corresponding position of pyramidal structure；Gap between the pyramidal structure 5 and taper groove 6
It is provided with elastic sealing element 4.
Notch 1-3 is equipped with the inside of taper groove inside floating seat, gap is set between the notch 1-3 and sealing ring
There are O-ring seals 3.The sealing ring 3 mainly plays the role of radial seal.Prevent granule materials from entering elastic sealing element with floating
The damage elastic sealing element of dynamic seat.
The taper of the taper groove is 20 °.The taper of the pyramidal structure is 15 °.Due to floating seat inner conical surface and sealing
The male cone (strobilus masculinus) taper of ring is different, forms the cone-shaped cavity of an outer narrow inner width together.Elastic sealing element between two conical surfaces, by
Compression produces elastic deformation, is installed on against two conical surfaces in hole；2 sealing ring surface opposites are installed in respective floating seat.This
Gap described in embodiment between two floating seats is 3mm, helps to extend the service life of sealing ring.The elastic packing
Part is 0 shape sealing ring.
The sealing principle of the utility model：
The sealing must use in pairs, only have a ring in two sealing rings and rotating, be between 2 sealing ring matching surfaces
Be mutually rotatable, i.e., one be stationary ring and it is another be rotating ring so as to constitute the floating sealing structure of prevent leakage.Elastic sealing element is made
Friction torque is transmitted to seal assembly for intermediary, is rotated by stiction driving sealing ring with floating seat, at the same time
Prevent sealing ring from being rotated with axis.The sealing surface of 2 sealing rings is handled using grinding technics, and elastic sealing element is acted on outside sealing ring
The axial thrust load of elastic force on the conical surface, as the axial load on sealing surface, is in close contact the matching trim of two sealing rings,
Ensure sealing efficiency.Radial component makes sealing ring automatic centering.As sealing surface wear increases, elastic sealing element release elastic force is real
Existing nose balance.Make under the comprehensive function of elastic sealing element elastic force metal o-ring keep float, mutually follow ensure that it is close
The reliability of envelope.
Described two sealing ring phase veneers form V-shaped gap structure 7, and the taper of the V-shaped gap structure 7 is 10 °.With profit
Enter sealing surface in lubricating oil.Must there be lubricant between sealing surfaces all the time.Interior pressure increases after centrifugal force and inner cavity heating
Big effect, is entered between two sealing surfaces by V shapes gap and generates one layer of oil film, fluid resistance realizes sealing, while plays profit
Sliding and cooling.
The sealing ring material of the utility model uses cast iron, it is desirable to which the hardness of sealing surface reaches HRC58-62.For sealing
Face will be ground, and make the surface smoothness of sealing surface 0.8.Using grease lubrication be suitable for linear velocity it is relatively low (v≤
In operating mode 0.8m/s).
In addition to the implementation, the utility model can also have other embodiment.It is all to use equivalent substitution or equivalent change
The technical solution to be formed is changed, is all fallen within the protection domain of the requires of the utility model.
