Abstract
The utility model provides a rotor dual-ring sealing device of a turbosupercharger. The rotor dual-ring sealing device comprises a rotating shaft of a turbosupercharger rotor, and the rotor dual-ring sealing device also comprises a turbine and an impeller which are respectively arranged on two ends of the rotating shaft, the junction of the turbine and the rotating shaft is provided with a radial projection A which is matched with a stator, the junction of the impeller and the rotating shaft is respectively provided with a radial projection B and an integral shaft seal which are mutually matched with a turbosupercharger shell, the radial projection A and the radial projection B are respectively provided with a turbine sealing groove and an impeller sealing groove between the turbine and the impeller, and a dual-ring sealing device M and a dual-ring sealing device N are respectively arranged in the turbine sealing groove and the impeller sealing groove. When the rotor dual-ring sealing device of the turbosupercharger is used for supercharging the turbine of an engine, waste gas exhausted by the engine drives the turbine to rotate, the turbine drives the coaxial impeller, and the impeller compresses the air into an air cylinder so as to enable fuel to be more adequately combusted, so that the power of the engine is improved. Known from the working process, when the rotor dual-ring sealing device of the turbosupercharger is used for supercharging the turbine, lubricating oil and air are not easy to leak, so that the application effect of the turbosupercharger is improved; and meanwhile, the service life of the turbosupercharger is also prolonged.
Description
Technical field
The utility model relates to the turbine field, is specifically related to a kind of turbocharger rotor ring sealing device.
Background technique
As everyone knows, the working principle of turbosupercharger is to promote turbine in turbine chamber by the waste gas inertia impulsive force that motor is discharged, and turbine drives again coaxial impeller, and the air that the impeller compression is sent here by the air-strainer pipeline makes it supercharging and enters cylinder.Engine speed speeds, the waste gas velocity of discharge is synchronizeed with secondary speed and is speeded, and the impeller just more air of compression enters cylinder, and the pressure of air and density increase the more fuel that can burn, corresponding increase fuel quantity and adjust engine speed just can increase engine power.So turbosupercharger extensively is used on various automobiles.But because turbosupercharger is to work under the rugged environment of high speed, high temperature, so in a single day lubricant oil leak, sintering, affected the dynamic balancing of rotating shaft at once, and the time has been grown and will cause bearing wear, turbine carbon distribution, turbine and housing to scratch; In a single day air leaks, and directly affects pressurized effect, also can cause simultaneously impeller to scratch the phenomenons such as housing, and these have all directly affected the working life of turbosupercharger, even can cause the stuck situation of turbine when serious, and pressurized machine is directly damaged.Due to its performance characteristic at high speed, high temperature of turbosupercharger, the magnitude of interference of its seal ring apparatus can not be excessive again, and sealing can not be excessively tight, caused turbosupercharger to be restricted working life.
Summary of the invention
The purpose of this utility model is: overcome the deficiencies in the prior art, a kind of turbocharger rotor ring sealing device is provided, in the situation that do not increase the seal ring magnitude of interference, increased the sealing with seal ring, reduced leaking of lubricant oil and air, increase turbosupercharger Security, extended the working life of turbosupercharger.
Technical solution adopted in the utility model is:
the turbocharger rotor ring sealing device, comprise the rotating shaft of turbocharger rotor, also comprise turbine and the impeller of being located at respectively the rotating shaft two ends, described turbine and rotating shaft joint are provided with the radial protrusion A that cooperatively interacts with stator, impeller and rotating shaft joint are respectively equipped with the radial protrusion B that cooperatively interacts with turbocharger housing, whole shaft seal, described radial protrusion A, radial protrusion B respectively with turbine, between impeller respectively correspondence be provided with turbine seal groove and impeller seals groove, be respectively equipped with ring sealing device M and ring sealing device N in described turbine seal groove and impeller seals groove.
The further improvement project of the utility model is that the O-ring seal size in described ring sealing device M, ring sealing device N is identical.
The utility model further improvement project is that the external diameter of ring sealing device M and ring sealing device N is slightly larger than the notch diameter of seal groove.
The utility model further improvement project is that described ring sealing device M and ring sealing device N and turbine seal groove and impeller seals groove are interference fit.
The utility model further improvement project is, described turbine is fixed by the end of bolt C and rotating shaft one end, and impeller is fixed by the end of bolt D and the rotating shaft the other end.
The beneficial effects of the utility model are:
When carrying out the turbosupercharging of motor with the utility model, the discarded drive turbine rotation that motor is discharged, turbine drives coaxial impeller, and impeller pressurized air enters cylinder, makes fuel combustion more abundant, thereby has improved the power of motor.From above-mentioned working procedure as can be known, when carrying out turbosupercharging with the utility model, lubricant oil and air are difficult for leaking, and have improved the using effect of turbosupercharger; Also increased simultaneously the Security of turbosupercharger, extended the working life of turbosupercharger, the utility model can increase the service life more than 5000 hours.
