Abstract
The utility model relates to a volute of an exhaust gas turbocharger. The volute comprises a volute body, an exhaust inlet, a runner and an exhaust outlet, wherein the surface of the bottom of the exhaust inlet is provided with a boss; the exhaust inlet is provided with a wall; the wall divides the exhaust inlet into two identical inlets; the port of the exhaust inlet is provided with a flange which extends outwardly; a reinforced rid is arranged between the flange and the boss; the port of the exhaust outlet is provided with a bulge; installation holes are evenly distributed at the periphery of the bulge; and the exhaust inlet and the exhaust outlet are respectively connected with the runner. The volute of the exhaust gas turbocharger has the beneficial effects that the volute is large in strength, and is practical and durable.
Description
Technical field
The utility model relates to a kind of volute of exhaust-gas turbocharger.
Background technique
At present, turbosupercharger is to utilize the energy of motor combustion gas to improve engine charge density, owing to increase the low oil consumption characteristics of the high power of motor, uses quite extensive.Along with engine power density improves constantly the extensive use with exotic material, row's temperature of motor is increasingly high, and the intake temperature of volute also raises, and the material of volute own is proposed requirements at the higher level.The material of volute depends primarily on engine exhaust temperature; Along with the increase of delivery temperature, in order to satisfy reliability requirement, the content of elements such as the Ni in the material, Si need increase; But fragility also can increase when its heat resistance improved, to the reliability deleterious impact.
The model utility content
The technical problem that the utility model will solve is: based on the problems referred to above, a kind of volute of durable exhaust-gas turbocharger is provided.
The utility model solves the technological scheme that its technical problem adopted: a kind of volute of exhaust-gas turbocharger; Comprise volute body, exhaust entrance, runner and exhaust outlet, the lower surface of volute body is provided with boss, is provided with wall in the exhaust entrance; It is two identical inlets that wall is separated exhaust entrance; The oral area of exhaust entrance has outward extending flange, is provided with stiffening rib between boss and the flange, and the oral area of exhaust outlet is provided with convexity; Be evenly equipped with mounting hole around protruding, exhaust entrance is connected with runner respectively with exhaust outlet.
Further, the circumferential profile of volute body is a scroll casing shape.
Further, the cross section of boss is a rectangle.
Further, the circumferential profile of flange is a rectangle.
Further, protruding circumferential profile is petal, and petal quantity is six.
The beneficial effect of the utility model is: volute intensity is big, and is durable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the side view of the utility model.
Wherein: 1. volute body, 2. exhaust entrance, 3. runner, 4. exhaust outlet, 5. boss, 6. wall, 7. flange, 8. stiffening rib, 9. convexity, 10. mounting hole.
Embodiment
Combine accompanying drawing that the utility model is further described now.The schematic representation that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
The volute of a kind of exhaust-gas turbocharger as depicted in figs. 1 and 2; Comprise volute body 1, exhaust entrance 2, runner 3 and exhaust outlet 4, the lower surface of volute body 1 is provided with boss 5, is provided with wall 6 in the exhaust entrance 2; It is two identical inlets that wall 6 is separated exhaust entrance 2; The oral area of exhaust entrance 2 has outward extending flange 7, is provided with stiffening rib 8 between boss 5 and the flange 7, and the oral area of exhaust outlet 4 is provided with protruding 9; Be evenly equipped with mounting hole 10 around protruding 9, exhaust entrance 2 is connected with runner 3 respectively with exhaust outlet 4.
The circumferential profile of volute body 1 is a scroll casing shape, and the cross section of boss 5 is a rectangle, and the circumferential profile of flange 7 is a rectangle, and protruding 9 circumferential profile is petal, and petal quantity is six.
During actual the use, waste gas gets into from exhaust entrance 2, through runner 3, discharges from exhaust outlet 4 after the turbine rotation in the drive volute body 1.
