example 1
[0019] exist figure 1 , figure 2 and image 3 In the schematic diagram of the turbine blade profile of the starting torque converter for a hydraulic transmission locomotive shown, the turbine has two annular disks opposite and parallel to the turbine disks 1 and 2, and several blades are vertically fixed between the two annular disks. 3. They form cascades. These blades with the same structure and regularly arranged are all cylindrical shells with a leaf-like cross section. The front ends of these blades are all arranged on the inner diameter circle of the annular disk surface of the turbine disk, and the rear ends of these blades are all arranged on the outer diameter circle of the annular disk surface of the turbine disk. In the section of the above-mentioned blade, the two arc-shaped connecting lines from the front end to the rear end are different curves. The shape of the above-mentioned blades and the distance between the inner and outer sides can be expressed by a r...
