Abstract
The utility model discloses a kind of oil gas internal-combustion engine shroud ring.This oil gas internal-combustion engine shroud ring, comprises shroud ring body, and shroud ring inner body wall is made up of stepped upper inwall, middle inwall and lower inwall, and shroud ring body outer wall middle vehicle has the square groove of annular; Described shroud ring body lower surface vertically offers the U-type groove of ring-type, is provided with chamfering II bottom U-type groove, and U-type groove inwall is having L-type groove I near shroud ring body outer wall side car; The diameter of described upper inwall is less than the diameter of middle inwall, and middle inner diameter is less than lower inner diameter.The utility model structure is simple, and reasonable in design, easy to operate, precision is higher, coordinates closely, good dustproof effect, long service life, do not need frequent replacing, enhance productivity with internal combustion engine part, cost-saving.
Description
Technical field
The utility model relates to internal combustion engine fittings technical field, especially a kind of oil gas internal-combustion engine shroud ring being widely used in oil gas internal-combustion engine.
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 oil gas internal-combustion engine shroud ring of good dustproof effect.
The utility model solves the technological scheme that its technical problem adopts: a kind of oil gas internal-combustion engine shroud ring, comprise shroud ring body, shroud ring inner body wall is made up of stepped upper inwall, middle inwall and lower inwall, and shroud ring body outer wall middle vehicle has the square groove of annular; Described shroud ring body lower surface vertically offers the U-type groove of ring-type, is provided with two chamferings II bottom U-type groove, and U-type groove inwall is having L-type groove I near shroud ring body outer wall side car; The diameter of described upper inwall is less than the diameter of middle inwall, and middle inner diameter is less than lower inner diameter.
Further, described shroud ring body upper surface excircle car has L-type groove II.
Further, between described upper inwall and middle inwall, turning place is provided with chamfering I.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, easy to operate, shroud ring inner body wall is made up of stepped upper inwall, middle inwall and lower inwall, shroud ring body outer wall middle vehicle has the square groove of annular, shroud ring body lower surface vertically offers the U-type groove of ring-type, this structure precision is higher, easy to process, and error is less, shroud ring coordinates with internal combustion engine part closely, good dustproof effect, long service life, does 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, inwall 3., 4. descends inwall, 5. square groove, 6.U type groove, 7.L type groove I, 8.L type groove II, 9. chamfering I, 10. chamfering II.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Oil gas internal-combustion engine shroud ring as depicted in figs. 1 and 2, comprises shroud ring body 1, and shroud ring body 1 inwall is made up of stepped upper inwall 2, middle inwall 3 and lower inwall 4, and shroud ring body 1 outer wall middle vehicle has the square groove 5 of annular; Shroud ring body 1 lower surface vertically offers the U-type groove 6 of ring-type, is provided with two chamferings II 10 bottom U-type groove 6, and U-type groove 6 inwall is having L-type groove I 7 near shroud ring body 1 outer wall side car; The diameter of upper inwall 2 is less than the diameter of middle inwall 3, and middle inwall 3 diameter is less than lower inwall 4 diameter.
Shroud ring body 1 upper surface excircle car has L-type groove II 8; Between upper inwall 2 and middle inwall 3, turning place is provided with chamfering I 9.
This oil gas internal-combustion engine shroud ring structure is simple, reasonable in design, easy to operate, shroud ring body 1 inwall is made up of stepped upper inwall 2, middle inwall 3 and lower inwall 4, and shroud ring body 1 outer wall middle vehicle has the square groove 5 of annular, and shroud ring body lower surface vertically offers the U-type groove 6 of ring-type, this structure precision is higher, easy to process, and error is less, shroud ring coordinates with internal combustion engine part closely, good dustproof effect, long service life, does not need frequent replacing, enhance productivity, cost-saving.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
