Abstract
The utility model provides a turbine disk connected through an axial dowel, which means a disc drum (2) of a turbine disk (1) is inserted into the groove of the other turbine disk (1) and connected through an axial dowel (3). The utility model is characterized in that: the inner ring of the position where the dowel (3) is installed in the turbine disk is provided with a ring support (11), the outer ring of the dowel (3) is provided with a locked-coil ring (4) so as to ensure that the dowel (3) does not fall off. The turbine disk connected through an axial dowel of the utility model has the following advantages: ensure that the disk drum is connected reliably and the operation of the combustion engine can not be influenced by the falling-off of the dowel; convenient for maintenance.
Description
Technical field
The utility model relates to gas turbine, specifically, and the turbine dish of gas turbine.
Background technique
Because gas turbine requires turbine that will be arranged very long working life, so require very reliable of rotor.In the dish drum of rotor connects, various ways such as pin connection, welding are arranged.When adopting welding, all turbine dishes all will be made with commaterial, then take expensive material by maximum temperature entirely.The employing pin connects, and can adopt different materials by different temperatures, and can segmentation repair or change during maintenance, and still, general pin connects, even dashed hole or pcketing, at work because rotor high-speed rotates also might come off.
Summary of the invention
The turbine dish 1 that the radially pin 3 that the purpose of this utility model is to provide a kind of pin 3 can not come off connects.
The turbine dish that the utility model provides a kind of radially pin to connect, the dish drum 2 that is a turbine dish inserts in the notch of another turbine dish 1, with radially pin 3 connections, it is characterized in that: turbine dish 1 is installed pin 3 position inner rings supporting ring 11, lock silk ring 4 is equipped with in pin 3 outer rings, does not come off to guarantee pin 3.
The turbine dish that the radially pin that the utility model provides connects, the little pin 5 of its lock silk ring 4 usefulness is fixed on the turbine dish 1, does not come off to guarantee lock silk ring 4.
The turbine dish that the radially pin that the utility model provides connects, its turbine dish 1 is installed the annular light filling bar 12 that there is deformable interruption outer ring, pin 3 position, compresses lock silk ring 4 in order to interior pressure.
The turbine dish that the radially pin that the utility model provides connects, its advantage is: assurance dish drum is reliable to be connected, and can not influence the operation of combustion machine because of pin comes off; Be convenient to maintenance.
Description of drawings
Fig. 1 is the structural representation (axial section) that the turbine dish dish drum of radially pin connection connects;
Fig. 2 is the structural representation (radial section) that the turbine dish dish drum of radially pin connection connects;
Fig. 3 is the structural representation (A is to view) that the turbine dish dish drum of radially pin connection connects.
Embodiment
The turbine dish that connects of pin radially, the structure that its dish drum 2 connects is shown in Fig. 1～3, the dish drum 2 that is a turbine dish inserts in the notch of another turbine dish 1, with radially pin 3 connections, turbine dish 1 is installed pin 3 position inner rings supporting ring 11, and lock silk ring 4 is equipped with in pin 3 outer rings, and the little pin 5 of lock silk ring 4 usefulness is fixed on the turbine dish 1, turbine dish 1 is installed the annular light filling bar 12 that there is deformable interruption outer ring, pin 3 position, compresses lock silk ring 4 in order to interior pressure.
During installation, the dish drum 2 of V shape is inserted in the notch of another turbine dishes 1, it is fixing to squeeze into pin 3 then.Push up on the supporting ring 11 of turbine dish 1 pin 3 inner ends, be wrapped with a circle in the outer end of pin 3 with a complete lock silk and form lock silk ring 4, to lock silk ring 4 with two little pins 5 and be fixed on the turbine dish 1, compress lock silk ring 4 again in the annular light filling bar 12 with turbine dish 1.
In the maintenance of combustion machine,, when assembling once more, can come safetied pin 3 with the method that replacing lock silk and conversion light filling bar 12 compress if rotor needs dissembling inspection or repairing.
Claims (3)
1, a kind of turbine dish of radially pin connection, the dish drum (2) that is a turbine dish inserts in the notch of another turbine dish (1), with radially pin (3) connection, it is characterized in that: lock silk ring (4) is equipped with in pin (3) outer ring, and turbine dish (1) is installed pin (3) position inner ring supporting ring (11).
2, the turbine dish that connects according to the described radially pin of claim 1, it is characterized in that: described lock silk ring (4) is fixed on the turbine dish (1) with little pin (5).
