Wheel unit main shaft sealing device wearing ring.
The purpose of this utility model realizes by the following technical solutions:
A kind of novel high polymer nylon wearing ring, including the first nylon basic ring, the second nylon basic ring, the first nylon buckles component and the
Two nylon buckles components, the first nylon buckles component and the second nylon buckles component are separately mounted to the first nylon basic ring and the second nylon basic ring
On, it is characterized in that, running through at the fastening of described first nylon buckles component and the second nylon buckles component has 2 first be arranged symmetrically with
Bolt；Be provided with 2 grooves being arranged symmetrically with on described first nylon buckles component, the second nylon buckles component is provided with 2 right
When claiming the projection arranged, the first nylon buckles component and the second nylon buckles component to fasten, projection inserts in described groove；Described projection and
The screwed hole mutually run through when being additionally provided with fastening on the first nylon buckles component, described screwed hole for inserting the second bolt, and the
The axis of two bolts and the first bolt is mutually perpendicular to.
Preferably, described first nylon basic ring and the first nylon buckles component, the second nylon basic ring and the second nylon buckles component are one
Body formed.
Preferably, 2 times of the screw sections diameter of a diameter of second bolt of the screw sections of described first bolt.
The beneficial effects of the utility model are: 1, by arranging and mutually perpendicular second bolt of the first bolt so that wearing ring is not
There is attachment force the most in the circumferential, the most also have attachment force, be greatly reinforced the energy loosened after wearing ring prevents longtime running
Power；2, by changing former casting material, wear-resisting, the impact resistance utilizing that composite nylon material has, corrosion resistant feature, again
Make new-type wearing ring, promote the operational reliability of wearing ring further, reduce the cycle of unit C level maintenance, improve water
The utilization rate of wheel unit.

Detailed description of the invention
With the following Examples this utility model is further described.
Fig. 1 is wearing ring structural representation of the prior art.
A kind of novel high polymer nylon wearing ring as Figure 2-3, including first nylon basic ring the 1, second nylon basic ring 2,
One nylon buckles component 3 and the second nylon buckles component 4, the first nylon buckles component 3 and the second nylon buckles component 4 are separately mounted to
On one nylon basic ring 1 and the second nylon basic ring 2, and the first nylon basic ring 1 and first nylon buckles component the 3, second nylon basic ring 2
All it is formed in one with the second nylon buckles component 4.
Run through, at the fastening of the first nylon buckles component 2 and the second nylon buckles component 4, the first bolt 5 having 2 to be arranged symmetrically with.The
It is provided with 2 grooves being arranged symmetrically with 6 on one nylon buckles component 3, the second nylon buckles component 4 is provided with 2 and is arranged symmetrically with
Projection 7, when the first nylon buckles component 3 and the second nylon buckles component 4 fasten, projection 7 inserts in groove 6, projection 7 and
The screwed hole 9 mutually run through when being additionally provided with fastening on one nylon buckles component 3, screwed hole 9 for inserting the second bolt 8, second
Bolt 8 is mutually perpendicular to the axis of the first bolt 5, and the screw rod of a diameter of second bolt 8 of screw sections of the first bolt 5 cuts
2 times of face diameter.So after wearing ring fastens molding, the first bolt 5 mainly serves for ensuring circumference and is connected firmly, the second spiral shell
Bolt 8 mainly serve for ensuring radially connected firmly, it is contemplated that turbine shaft rotate during the tangential force of existing circumferencial direction, again
Having centrifugal force radially, this connection connects the most much than single circumference undoubtedly.
Meanwhile, first nylon basic ring the 1, second nylon basic ring the 2, first nylon buckles component 3 and the second nylon buckles component 4 are by height
Molecule composite nylon material is made.Macromolecule nylon (Nylon, Polyamide are called for short PA) refers to by high-molecular polyamide
The plastics that resinoid is constituted, this resinoid can be prepared by polycondensation with binary acid by diamine, adds asphalt mixtures modified by epoxy resin in polycondensation process
Fat and multiple additives can further improve the mechanical strength of its finished product, and its hot strength is higher than metal, and compressive strength is with metal not
Upper and lower mutually, by adding other composites, the purer nylon material of rigidity significantly improves.Because nylon material has endurance, rubs
Wiping coefficient is little, corrosion-resistant, lightweight, the feature of easy shaping, can be widely used for auto industry, electronics industry and machine-building work
Industry.This wearing ring is by changing casting material, according to the size of former main shaft seal wearing ring, purchases dimension macromolecule and is combined
Nylon plate, is processed in machining factory according to original design size, by the macromolecule nylon wearing ring of completion of processing at unit
Installing in during maintenance, it has the advantage that the wear-resistant coefficient of (1) its material is 2-3 times of 30# steel, resistance to abrasion
Can be 1.5 times of 30# steel, shearing be slightly 30-40MPa, and fatigue performance highlights, and can meet water turbine set wearing ring to material
The requirement of matter；(2) possessing certain water absorption due to nylon material (PA), its saturation water reaches more than 3%, will be in certain journey
The mechanical strength of its material and the stability of processing dimension is reduced, by using macromolecule nylon to add epoxy resin and multiple on degree
After additive Combined Processing, its material water absorption significantly reduces；(3) as movable mechanical member, because its material has water absorption
And self lubricity, when unit operation, composite nylon conversion is little with sealing ring relative motion coefficient of friction, and conversion erosion degree shows
Write and reduce, further increase the water sealing effect of main shaft seal.
Last it should be noted that, above example is only in order to illustrate the technical solution of the utility model, rather than to this utility model
The restriction of protection domain, although having made to explain to this utility model with reference to preferred embodiment, the ordinary skill people of this area
Member should be appreciated that and can modify the technical solution of the utility model or equivalent, without deviating from this utility model skill
The spirit and scope of art scheme.
