Gas turbine high speed end-tooth axis

1,In the aero-engine, on the connection part between compressor rotor with turbine rotor was completed by arc end-tooth and transferring to the torque.  On the end surface of the centrifugal compressor rotor, there are the arc end tooth. This arc end tooth was developed by US “GIJL SON”company in 1942, since that time which was begun used widely and popularized step by step in aero-engine as well as the other industry in the developed countries just like European ,American and Japan. The feature of which is provided by accuracy of mesh and perfect self-centering to transfer bigger torque and can divide complex entirety construction into a few simple construction to be convenient for designing and manufacturing and assembling.

2,Face tooth is important parts of connection and torque transmission in gas turbine and aero-turbine engine . 3,The rotor structure and technological characteristics of the gas turbine are as bellow: model V943A heavy duty gas turbine unit was introduced new type combined cycle gas turbine unit, the rotor of which is corona pull level stype construction including 19 Grade turbine and 3 hollow shaft, all the parts pulled tightly by one centered pull rod and all the torques among the each units should transfer through the face tooth (HIRTH).

This production was mainly used on gas turbine and turbine engine, now which was widely presented and applied in the field of space flight and aviation, naval vessels, high-speed locomotive, advanced auto, tanks, energy and machines etc.
