Abstract
The utility model discloses a steam turbine main oil pump coupler. The steam turbine main oil pump coupler comprises a middle sleeve, a membrane, a Z-type spacer, a steam turbine rotor and a main oil pump rotor. The steam turbine rotor and the main oil pump rotor are connected through the middle sleeve, wherein the membrane and the Z-type spacer are installed on the connecting position, and the stress surface of the Z-type spacer and the stress surface of the membrane are on the same plane. The steam turbine main oil pump coupler has the advantages that axial thrust of the main oil pump is jointly born by the Z-type spacer and the elastic membrane instead of independently born by the Z-type spacer, and therefore the purposes of prolonging service life and improving stability are achieved.
Description
Technical field
The utility model relates to the coupling technical field, particularly a kind of steam turbine main oil pump coupling.
Background technique
At present, in the joint of turbine rotor and main oil pump rotor and intermediate sleeve, Z-shaped pad makes it cracked easily owing to stressed excessive.
The model utility content
The purpose of this utility model is at the defective of prior art and deficiency, provides a kind of Z-shaped pad to have diaphragm simultaneously stressed, the steam turbine main oil pump coupling of Z-shaped pad long service life.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of steam turbine main oil pump coupling described in the utility model, comprise intermediate sleeve, diaphragm, Z type pad, turbine rotor, main oil pump rotor, described turbine rotor, main oil pump rotor connect by intermediate sleeve, the joint is equipped with diaphragm and Z type pad, and the stress surface of described Z type pad and diaphragm is in the same plane.
After adopting said structure, the utility model beneficial effect is: the end thrust of main oil pump independently is born by Z-shaped pad transform as Z-shaped pad and flexible sheet is born jointly, reaching increases the service life improves stable purpose.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Description of reference numerals:
1. intermediate sleeve, 2. diaphragm, 3.Z type pad, 4. turbine rotor, 5. main oil pump rotor.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of steam turbine main oil pump coupling described in the utility model, comprise intermediate sleeve 1, diaphragm 2, Z type pad 3, turbine rotor 4, main oil pump rotor 5, described turbine rotor 4, main oil pump rotor 5 connect by intermediate sleeve 1, the joint is equipped with diaphragm 2 and Z type pad 3, the stress surface of described Z type pad 3 and diaphragm 2 is in the same plane, the end thrust of main oil pump independently born by Z-shaped pad 3 transform Z-shaped pad 3 as and flexible sheet 3 is born jointly, reaching increases the service life improves the purpose of stability.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
