| description | The invention relates to the technical field of water turbine rotors, aims to solve the problem of how to conveniently and quickly perform static balance test on a water turbine rotor, and provides a static balance test device. The static balance test device comprises a concave sphere, a convex sphere and a flange plate. The concave sphere comprises a concave spherical surface. The convex sphere comprises a convex spherical surface and a mounting surface which are arranged oppositely, the convex spherical surface corresponds to the concave spherical surface in the vertical direction, and the convex spherical surface can be stressed and suspend on the concave spherical surface. The flange plate is fixedly connected with the mounting surface and can drive the convex sphere to rotate on the concave spherical surface when being stressed. According to the static balance test device, the friction force between the convex spherical surface and the concave spherical surface is almost zero; the flange plate bears the |
