Embodiment 1
[0022] see Figure 1 to Figure 5 , the present invention provides a technical solution: a blade structure for reducing noise and air loss of a hydraulic retarder, including a stator 1 and a rotor 2, the stator 1 is located on one side of the rotor 2, and the inner side of the stator 1 and the rotor 2 is provided with The blades 3, the blades 3 in the stator 1 and the rotor 2 are all arranged in a circular array, and the edge of one end of the blade 3 is fixed with a saw-toothed bar 4, and the designed saw-toothed bar 4 is installed on the blade 3, thereby realizing the Changing the tooth shape of rotor 2 and stator 1 has the effect of reducing noise and drag. There are tooth grooves on the sawtooth bar 4, and the tooth grooves are located on the sawtooth bar 4 in a half-sine wave. The cogging on the top is set with sine wave fluctuations, thereby ensuring that the sawtooth bar 4 changes the eddy current intensity in the working chamber of the rotor 2 and the stator 1, which ca...
