Definitions
- the spinning disk is made integral from one of the other units. Forests with such wide discs of char- acter 15 can be used for working with high speed disks (from 120 to 300 m / s).
- connection is complete with either a method of welding, or a clamp.
- Forest in the case of an incisive disks, it was completed as part of such a connection - / C - ⁇ l ⁇ na with ⁇ lshm, imee ⁇ meny ⁇ uyu ⁇ ud ⁇ em ⁇ s ⁇ and me ⁇ al- l ⁇ em ⁇ s ⁇ , ⁇ s ⁇ avneniyu with ⁇ les ⁇ m, y ⁇ g ⁇ ⁇ yvayu- conductive dis ⁇ vy ⁇ lnen solid, n ⁇ vys ⁇ uyu na ⁇ yazhenn ⁇ s ⁇ s ⁇ edineniya ⁇ l ⁇ na ⁇ g ⁇ ltsa, ch ⁇ delae ⁇ nev ⁇ zm ⁇ zhnym 5 ⁇ imenenie ⁇ a ⁇ i ⁇ ⁇ les for ⁇ ab ⁇ y with ⁇ uzhnymi with speeds above 120 m / s.
- the main task of the invention is to create a working wheel of the wheel at the connection of the invention.
- the posed problem is solved in that, in particular,
- 25 total tension values (the difference between the available diameters of the ring and the load) is in the interval from I to 1.5 * 10 _ ⁇ , where Bo is the internal diameter.
- the lower limit of the tightness value ⁇ * ⁇ 0 ⁇ ⁇ ⁇ is due to the possibility of mechanical processing of the overpressure
- Foreigners II and 12 are related to 8th and 8th and 3rd and 13th to 2nd 5th are not connected to 8 and are not connected to the car.
- the centrifugal chamber When the rotary wheel is rotated, the centrifugal chamber is equipped with centrifugal forces. Like a 2 blade, it is shared with Disk I and Disk 4
