[0018] In the prior art, the housing of the steam turbine coupling cannot adjust the height, making it difficult to adaptively install couplings of different heights, causing certain inconvenience to equipment installation and restricting the flexible application of the coupling housing under different working conditions.

The connecting seat 10 is cooperatively connected with the connecting plate 4, and the connecting seat 10 is fixedly connected to the connecting plate 4 through a fixing bolt 11. The fixing bolt 11 is threadedly connected to the adjustment screw hole 5;

[0022] In the specific implementation process, it is particularly worth noting that the base 1 is used to be fixed to the ground or other fixed surfaces below the coupling. Through the cooperation between the base 1, the arc-shaped cover 2 and the side plates 3, the main structure of the steam turbine coupling housing is formed.

Through the cooperation between the side plate 3, the connecting plate 4, the adjustment screw hole 5, the connecting seat 10 and the fixing bolt 11, by clamping the connecting plate 4 into the groove of the connecting seat 10 and screwing the fixing bolt 11 into the adjustment screw hole 5, the fixation between the connecting plate 4 and the connecting seat 10 is realized. And by fixing the fixing bolt 11 in the adjustment screw holes 5 at different heights, the fixed height of the side plate 3 can be adjusted.
