Description
Technical Field

[0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It belongs to the turbine machinery in fluid machinery. During the use of a water turbine, a thrust washer is required. The thrust washer is also called a thrust bearing. It is used to balance the axial thrust of the rotor. It establishes the dead point of rotor expansion, thereby ensuring that the axial clearance between the moving and static parts is within the design range. During the manufacturing process, the thrust washer needs to be drilled, and during the drilling process, a supporting structure is needed to support the thrust washer, thereby facilitating its drilling.
[0003] During the drilling process of existing thrust washers, the supporting structure mostly plays the role of supporting and limiting the thrust washers. However, when thrust washers of different sizes are loaded, it is not convenient to clamp and position them, and the staff needs to manually adjust the position of the thrust washers, thereby reducing the processing efficiency of the thrust washers. For this reason, we propose a supporting structure for the thrust washers of turbines. Utility Model Content
