Description
Technical field
The present invention relates to booster turbine dish and main shaft structure technical field, be specifically related to a kind of internal-combustion engine vehicle supercharger turbine dish and main shaft connecting structure.
Background technique
In internal-combustion engine vehicle supercharger, the effect of the turbine disk is that upper tenon tooth connection turbine moving blade is equipped forms turbine disc by coiling, turbine moving blade on turbine disc utilizes the waste gas of discharging in cylinder of diesel engine to make mechanical work, by the turbine disk and main shaft connecting structure, mechanical energy is rotated by main shaft drives pressure booster blower impeller, by air intake also compression raising air pressure, thus provide enough air to cylinder of diesel engine, make diesel oil Thorough combustion, reduce oil consumption and improve engine fuel economy, reduce delivery temperature and heat load simultaneously, improve Reliability of Diesel Engine.In existing technology, turbine disk material is GH2132, and spindle material is 42CrMo, is connected by main shaft by Friction welding technique with the turbine disk.Along with internal combustion locomotive power continually strengthens lifting and emission regulation demands raising, need the corresponding raising of pressurized machine pressure ratio.In application pressure ratio 3.5 ~ 4.5 scope, supercharger speed improves more than 30%, and respective turbine dish tenon tooth surface of contact bearing stress significantly promotes, and the GH2132 material turbine disk originally can not meet user demand; Need the turbine disk changing the higher material of intensity, the new material turbine disk, due to different material characteristics, cannot make the turbine disk at present together with main shaft friction welding, cannot meet welding technique requirement.
Summary of the invention
The invention provides a kind of combustion engine vehicle supercharger turbine dish and main shaft connecting structure, the transmission of application solutions pressurized machine internal mechanical merit, improve the reliability of high pressure ratio pressurized machine work.
The technical solution adopted in the present invention is internal-combustion engine vehicle supercharger turbine dish and main shaft connecting structure, spindle nose is provided with recessed blind hole, the middle part of the turbine disk be connected with main shaft is provided with positioning boss, recessed blind hole and positioning boss suitable, main shaft and the turbine disk are bolted, main shaft and the turbine disk to be located by connecting transmitting torque by straight pin, and straight pin and bolt are circumferentially arranged at interval at the turbine disk, and the periphery of the turbine disk connects turbine moving blade by tenon tooth.
Described bolt quantity is at least 3.
The quantity of described straight pin is at least 3.
The material that the described turbine disk adopts is GH4169.
The diameter range of described positioning boss is 28mm ~ 12mm, and the diameter range of recessed blind hole is 28mm ~ 12mm.
The invention has the beneficial effects as follows: the turbine disk adopts new material GH4169, can better adapt to due to pressurized machine pressure ratio improve, rotating speed improves and the stress that brings improves, and improves turbine disk reliability; There is provided a kind of Novel turbine dish and main shaft connecting structure, the transmission of application solutions pressurized machine internal mechanical merit, improve high pressure ratio pressurized machine functional reliability.
