Abstract
The present invention discloses a kind of integrated jet nozzle ring for supercharger. The integrated jet nozzle ring includes a heat blocking plate with central hole, several blades on one side of the heat blocking plate, and ring lug on the other side of the heat blocking plate, and is made of heat resistant cast steel. The present invention has the technological scheme of integrating two independent parts into one, and thus has simplified structure, lowered cost, no deformation caused by varying temperature, and long service life.
Description
Technical field
The present invention relates to a kind of internal-combustion engine booster, specifically, relate to a kind of internal-combustion engine booster nozzle ring structure.
Background technique
Usually the structure of internal-combustion engine booster turbine end is generally turbine case, turbine, nozzle ring, formations such as heat shield, nozzle ring and heat shield are for dividing body structure, be illustrated in figure 1 as the employed heat shield of common internal-combustion engine booster, heat shield 4 for having a bowl structure of center hole 2, as shown in Figure 2, nozzle ring comprises annular base plate 5, annular base plate 5 surroundings evenly are provided with nozzle blade 1, the central position of annular base plate 5 has the center hole 3 that can hold heat shield and cooperate with heat shield, the heat shield material is generally heat resisting cast iron, the nozzle ring material is generally heat resisting cast steel, and the shortcoming of this kind structure is that the exhaust gas temperature of discharging during owing to pressurized machine work is very high, can reach four or five hundred degree, the different expanded by heating with the heat shield material of nozzle ring are different, cause part deformation, usually make pressurized machine draw shell, cause whole pressurized machine to be scrapped, influence the proper functioning of machine, two parts integrators use and also cause cost higher simultaneously, the structure more complicated.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, cost is lower, the supercharger integrated jet nozzle ring that working life is long.
For achieving the above object, technological scheme of the present invention is: supercharger integrated jet nozzle ring, it is characterized in that: described integrated jet nozzle ring comprises the nozzle ring heat shield, the central position of described nozzle ring heat shield is provided with center hole, the periphery of described nozzle ring heat shield one side evenly is provided with several nozzle blades, and the periphery of described nozzle ring heat shield opposite side is provided with annular projection.
Below be the further improved technological scheme of such scheme:
The diameter of axle of the aperture of described center hole and pressurized machine central shaft is complementary.
The periphery of the annular projection that described nozzle ring heat shield periphery is provided with is provided with the rim of the mouth that is used for sealing.
The material of described integrated jet nozzle ring is a heat resisting cast steel.
Beneficial effect: the technical solution adopted in the present invention will be originally independently two parts unite two into one, when reaching the function that both possess, make overall structure simpler, cause cost to reduce, whole nozzle ring adopts the heat resisting cast steel material to form, not different part deformation problems that produce of expanded by heating simultaneously of original nozzle ring and heat shield material have been overcome, avoided pressurized machine to draw shell, can effectively increase actual life, have actual preferably use value and marketing meaning.
The present invention is further illustrated below in conjunction with drawings and Examples
