Abstract
The invention belongs to the technical field of sealing rings, and particularly relates to a ceramic sealing ring. The ceramic sealing ring comprises a sealing ring body, and a mounting hole axially penetrating through the sealing ring body is formed in the center of the sealing ring body. The ceramic sealing ring is characterized in that a transition hole is further formed in the center of the sealing ring body, the diameter of the transition hole is larger than that of the mounting hole, and the transition hole does not penetrate through the lower surface of the sealing ring body; a plurality of oil storage grooves are formed in the outer edge of the sealing ring body from the upper surface of the sealing ring body to the lower surface of the sealing ring body without penetrating through the lower surface of the sealing ring body; the sealing ring body, the mounting hole, the transition hole and the oil storage grooves are integrally formed. The ceramic sealing ring has the advantages of being easy to manufacture, high in finished product qualification rate and low in cost, has both sealing performance and lubricating performance, and is longer in service life and smaller in temperature deformation.
Description
Technical field
The invention belongs to the seal ring technical field, especially relate to a kind of seal ring of using be used to being arranged on seal ring on internal combustion engine or gold machining grinding equipment.
Background technique
In prior art, the most of rubber that adopts of the seal ring that seal ring on internal combustion engine or gold machining grinding equipment are used is made, because the rubber oil resistance is relatively poor, and in the situation that friction repeatedly, the very easily aged deterioration due to heating of rubber, therefore, seal ring becomes damageable spare parts, need often to change, brought great inconvenience and unnecessary expenditure to the user.
Summary of the invention
In order to address the above problem, the present invention discloses a kind of ceramic seal circle, and it not only can realize seal action, and owing to having adopted stupalith, thermal change almost can be ignored, heat-resisting more than 1000 degrees centigrade, and the life-span is extremely long, and easily produce, cost is extremely low; The present invention realizes by the following technical solutions.
A kind of ceramic seal circle, it includes seal ring body 1, the seal ring body center has the mounting hole 3 of axial perforation seal ring body, it is characterized in that the seal ring body center also has a transitional pore 2, the diameter of transitional pore is greater than the diameter of mounting hole and the lower surface that transitional pore does not run through the seal ring body; Outward edge at the seal ring body has a plurality of oil storage grooves 4, and the direction of oil storage grooves is for the lower surface from the upper surface of seal ring body to the seal ring body but do not run through the lower surface of seal ring body; Seal ring body, mounting hole, transitional pore, oil storage grooves are formed as one.
Ceramic seal circle described above, the quantity that it is characterized in that described oil storage grooves are 2 or 3 or are greater than 3 integer.
Ceramic seal circle described above, is characterized in that described oil storage grooves is the outer rim that is distributed in symmetrically the seal ring body.
Ceramic seal circle described above, the material that it is characterized in that described seal ring body are aluminium oxide ceramics or silicon oxide ceramics or silicon carbide ceramics.
The present invention in use, be fixed on seal ring on internal combustion engine or the piston of gold machining grinding equipment on, seal ring moves with piston, in movement process, the oil part is stayed in oil storage grooves, when realizing sealing function, also realized lubricated for cylinder side wall, the existence of transitional pore make install more convenient, install more firm.
Because stupalith has good spalling resistance performance and high temperature resistant more than 1000 degrees centigrade, therefore, the present invention's thermal deformation behavior in use is minimum; After using the present invention, internal-combustion engine or gold machining grinding equipment can be used continuously for a long time; After having made mould, by the mode of mold pressing, can complete the manufacture of idiosome corresponding to the present invention, after the idiosome manufacture completes, put into step-by-step movement cellar for storing things stove sintering and namely can be made into finished product, therefore can realize, produce in enormous quantities, therefore, and low cost of manufacture, product price is low; Because stupalith hardness is very big, therefore, even through repeatedly friction, the wearing and tearing of this product are very little, therefore, and longer service life of the present invention.
Therefore, the present invention has following main beneficial effect: making is simple, product qualified rate is high, cost is low; Not only have sealability and also have a greasy property, this product longer service life, temperature deformation are less.

Embodiment
Embodiment
Ask for an interview Fig. 1-Fig. 3, a kind of ceramic seal circle, it includes seal ring body 1, the seal ring body center has the mounting hole 3 of axial perforation seal ring body, it is characterized in that the seal ring body center also has a transitional pore 2, the diameter of transitional pore is greater than the diameter of mounting hole and the lower surface that transitional pore does not run through the seal ring body; Outward edge at the seal ring body has 3 oil storage grooves 4, and the direction of oil storage grooves is for the lower surface from the upper surface of seal ring body to the seal ring body but do not run through the lower surface of seal ring body; Seal ring body, mounting hole, transitional pore, oil storage grooves are formed as one.
Ceramic seal circle described above, the quantity that it is characterized in that described oil storage grooves can also be 2 or 4 or be greater than 4 integer.
Ceramic seal circle described above, is characterized in that described oil storage grooves is the outer rim that is distributed in symmetrically the seal ring body.
Ceramic seal circle described above, the material that it is characterized in that described seal ring body are aluminium oxide ceramics or silicon oxide ceramics or silicon carbide ceramics.
The present invention in use, be fixed on seal ring on internal combustion engine or the piston of gold machining grinding equipment on, seal ring moves with piston, in movement process, the oil part is stayed in oil storage grooves, when realizing sealing function, also realized lubricated for cylinder side wall, the existence of transitional pore make install more convenient, install more firm.
Because stupalith has good spalling resistance performance and high temperature resistant more than 1000 degrees centigrade, therefore, the present invention's thermal deformation behavior in use is minimum; After using the present invention, internal-combustion engine or gold machining grinding equipment can be used continuously for a long time; After having made mould, by the mode of mold pressing, can complete the manufacture of idiosome corresponding to the present invention, after the idiosome manufacture completes, put into step-by-step movement cellar for storing things stove sintering and namely can be made into finished product, therefore can realize, produce in enormous quantities, therefore, and low cost of manufacture, product price is low; Because stupalith hardness is very big, therefore, even through repeatedly friction, the wearing and tearing of this product are very little, therefore, and longer service life of the present invention.
Therefore, the present invention has following main beneficial effect: making is simple, product qualified rate is high, cost is low; Not only have sealability and also have a greasy property, this product longer service life, temperature deformation are less.
The present invention is not limited to above-mentioned preferred forms, should be appreciated that design of the present invention can be by other various forms enforcement utilizations, and they drop in protection scope of the present invention equally.
