Description
Technical Field
The utility model mainly relates to the field of turbochargers, especially, relate to a streamlined thin blade turbocharger rotor shaft.
Background
The turbo-charger is an additional device for increasing the power of gasoline or diesel internal combustion engine under the condition of unchanged engine displacement, and utilizes the waste gas discharged from the exhaust passage of the internal combustion engine to drive a turbine, the turbine drives a pneumatic impeller to rotate through a rotor shaft, and the impeller pumps the air delivered from the pipeline of an air filter to compress the air into an engine cylinder, so that the air intake amount of the engine cylinder is increased by increasing the air density, and then the oil inlet amount is increased, so that the engine can achieve the purpose of increasing the power without increasing the displacement.
In a conventional turbocharger, a rotor shaft of the turbocharger is an important key component, when the rotating speed of an engine is increased, the middle end of the rotor shaft is cracked due to the excessive pressure borne by an impeller end, and the service life of the rotor shaft of the turbocharger is seriously influenced.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned defect of prior art, the utility model provides a streamlined thin blade turbocharger rotor shaft, including rotor shaft body 1, 1 middle-end part of rotor shaft body is equipped with boss 2, latch segment 3 and impeller 4 from the right side to left side in proper order the cover, the fixed fixture block 5 that is equipped with on the rotor shaft body 1, fixture block 5 is located 3 left ends of latch segment, fixture block 5 is used for fixed impeller 4.
Preferably, the fixture block 5 is clamped in a clamping groove on the inner side wall of the impeller.
Preferably, the locking piece 3 is rotatably mounted with the rotor shaft body 1 by means of a thread.
Preferably, the rotor shaft body 1 is further sleeved with a rubber ring 6, and the rubber ring 6 is located between the locking block 3 and the impeller 4.
Preferably, the end of the rotor shaft body 1 away from the impeller 4 is provided with an external thread 7.
Preferably, the rotor shaft body 1 is fixedly mounted with a nut 8 adjacent the impeller 4 end.
Preferably, the rotor shaft body 1 and the reinforcing block 2 are in interference fit.
The utility model has the advantages that:
through set up the latch segment at the impeller end, from source locking impeller, strengthen the stability of impeller work, establish the boss through the cover in rotor shaft middle section, further consolidate the rotor shaft, improve the life of turbo charger rotor shaft.
