Description
Technical field
The utility model 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.
Model utility content
The technical problems to be solved in the utility model 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 utility model solves the technological scheme that its technical problem adopts: 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 beneficial effects of the utility model are: the utility model structure 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.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the A portion enlarged view in Fig. 1.
Wherein: 1. shroud ring body, 2. go up inwall, 3. descend inwall, 4.V type groove, 5. circular groove, 41. first vertical section of cell wall, 42. first oblique line section cell walls, 43. arc cell walls, horizontal segment cell wall on 51., 52. second vertical section of cell wall, 53. second oblique line section cell walls, 54. times horizontal segment cell walls.
