Therefore, they should not be construed as limitations on this utility model.

[0020] Please see Figure 1-3This utility model provides a technical solution: a nozzle ring for a turbocharger, comprising a ring body 1 and guide vanes 2. A plurality of guide vanes 2 are evenly arranged on one side of the ring body 1, and all guide vanes 2 are obliquely arranged on the surface of the ring body 1. Reinforcing protrusions 7 are provided at the connection points between the guide vanes 2 and the ring body 1 to ensure the connection strength between the guide vanes 2 and the ring body 1. The width of the guide vanes 2 gradually increases from the inside out, and both ends of the guide vanes 2 are arc-shaped. This structure of the guide vanes 2 can minimize resistance. A flow channel is formed between adjacent guide vanes 2, and the distance between adjacent guide vanes 2 gradually decreases from the outside in, to ensure that exhaust gas can be blown directionally from all directions. For the turbine blades in the turbocharger, an extension plate 3 is provided at the end of the ring body 1 away from the guide vane 2. A groove 4 is opened on the outer surface of the ring body 1. Several reinforcing plates 5 are evenly arranged in the groove 4 of the ring body 1. The outer end of the reinforcing plate 5 is flush with the outer wall of the ring body 1 to cooperate with the corresponding installation position in the turbocharger. A limiting boss 6 is provided on the inner side of the end of the ring body 1 near the guide vane 2. An annular sealing groove 8 is opened on the side of the extension plate 3 away from the guide vane 2 for installing a sealing ring, so as to ensure the sealing performance of the extension plate 3 as the mating surface with the turbocharger. A positioning groove 9 is provided on one side of the extension plate 3 for positioning to prevent the nozzle ring from rotating during use.

[0021] Manufacturing method and operating principle: First, an assembly of ring body 1 and guide vane 2 is prepared. The guide vane 2 and ring body 1 can be integrally formed or welded together. Then, the outer wall of ring body 1 is machined with a groove 4 and a reinforcing plate 5. Next, the inside of ring body 1 is machined and a limiting boss 6 is reserved. At the same time, an annular sealing groove 8 is machined at the outer end of extension plate 3. Finally, a positioning groove 9 is opened on one side of extension plate 3, completing the nozzle ring involved in this application. The material cut off can be recycled. During installation, the sealing ring is placed in the annular sealing groove 8 to ensure sealing. The nozzle ring is installed in the corresponding position of the turbocharger and secured with a gland to complete the installation. Exhaust gas enters from the flow channel between the two guide vanes 2 and blows towards the turbine blades, thereby driving the turbine to rotate. This utility model has a reasonable structure. The outer periphery of ring body 1 has a groove 4, and a reinforcing plate 5 is evenly reserved in the groove 4. The reinforcing plate 5 ensures the structural strength of the nozzle ring. At the same time, the groove 4 makes the nozzle ring lighter and saves materials, thereby reducing production costs.
