Abstract
The invention discloses the technical field of accessories of an internal combustion engine, and particularly relates to a novel shield ring for the internal combustion engine. The novel shield ring for the internal combustion engine comprise a shield ring body, wherein the inner wall of the shield ring body consists of a stepped upper inner wall and a stepped lower inner wall, and an annular groove is vertically turned in the shield ring body; an annular V-shaped groove is vertically formed in the lower surface of the shield ring body; the diameter of the upper inner ring is smaller than that of the lower inner wall. The novel shield ring is simple in structure, reasonable in design, convenient in operation, higher in precision, good in dustproof effect and long in service life, is tightly matched with components of the internal combustion engine, and does not need to be changed frequently, so that the production efficiency is improved, and the cost is reduced.
Description
Technical field
The present invention relates to internal combustion engine fittings technical field, especially a kind of internal combustion engine shroud ring.
Background technique
Internal-combustion engine is a kind of dynamic power machine, and it is by making fuel burn at machine intimate, and the heat energy of being released directly is converted to the heat engine of power.Sensu lato internal-combustion engine not only comprises stroke piston combustion engine, rotary engine and free piston engine, also comprise the gas turbine of rotary vane type, jet engine etc., but usually said internal-combustion engine refers to internal-combustion piston engine.Internal-combustion piston engine is the most general with reciprocating piston type.Internal-combustion piston engine, by fuel and air mixing, burns in its cylinder combustion, and the heat energy discharged makes the combustion gas producing High Temperature High Pressure in cylinder.Combustion gas is expanded and is promoted piston work done, then mechanical work is exported by connecting rod or other mechanisms, drives follower work.Shroud ring is an indispensable vitals in internal-combustion engine, prevents the fine particles such as dust from entering in internal-combustion engine, affects the work of internal-combustion engine.Traditional shroud ring complex structure, dust-proof effect and working life are all undesirable.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of structure simple, the internal combustion engine shroud ring of good dustproof effect.
The technical solution adopted for the present invention to solve the technical problems is: a kind of internal combustion engine shroud ring, comprises shroud ring body, and shroud ring inner body wall is made up of stepped upper inwall and lower inwall, and the vertical car of shroud ring body outer wall has circular groove; Described shroud ring body lower surface vertically offers the V-type groove of ring-type, V-type groove comprises first vertical section of cell wall and the first oblique line section cell wall, connected by arc cell wall between first vertical section of cell wall and the first oblique line section cell wall, first vertical section of cell wall is arranged perpendicular to shroud ring body lower surface, and the inclined angle alpha of the first oblique line section cell wall and horizontal plane is 40 ~ 50 °; The diameter of described upper inwall is less than the diameter of lower inwall;
Described circular groove comprises horizontal segment cell wall, second vertical section of cell wall, the second oblique line section cell wall and lower horizontal segment cell wall, and upper horizontal segment cell wall and lower horizontal segment cell wall are arranged perpendicular to shroud ring body outer wall.
Further, described upper horizontal segment cell wall length is greater than lower horizontal segment cell wall length.
Further, described inclined angle alpha is 43 °.
The invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, easy to operate, shroud ring body lower surface vertically offers the V-type groove of ring-type, V-type groove comprises first vertical section of cell wall and the first oblique line section cell wall, connected by arc cell wall between first vertical section of cell wall and the first oblique line section cell wall, first vertical section of cell wall is arranged perpendicular to shroud ring body lower surface, the inclined angle alpha of the first oblique line section cell wall and horizontal plane is 40 ~ 50 °, this structure precision is higher, process easy, error is less, shroud ring is coordinated with internal combustion engine part closely, good dustproof effect, long service life, do not need frequent replacing, enhance productivity, cost-saving.
