Embodiment 1

[0042] Such as figure 2 As shown, it is a wheel back structure diagram of a low moment of inertia turbine provided by Embodiment 1 of the present invention. The blank part in the right figure is the part removed compared with the existing turbine, and the shaded part is the retained wheel back and ribs. A structure in which 5 center-radiating reinforcing ribs are evenly arranged is adopted, the cross-section of the reinforcing ribs is rectangular, and the width and thickness of each section of each of the reinforcing ribs are equal.

[0043] Compared with the existing turbine, the low moment of inertia turbine provided by Embodiment 1 of the present invention is 9% lighter in weight and 7% lower in moment of inertia. Compared with the center of mass of the rotating system composed of corresponding components, the existing turbine rotating system is biased towards the floating bearing at the compressor end. The displacement is 2.2mm, which effectively improves the low-speed re...

Abstract

The invention discloses a design method for a low-rotary-inertia turbine. The design method comprises the steps that a primary scheme for the low-rotary-inertia turbine is set, and a digital model of an existing turbine and a digital model of the primary scheme of the low-rotary-inertia turbine are built; stress analysis is conducted on the exiting turbine and the primary scheme of the low-rotary-inertia turbine; stress analysis results are processed. According to the low-rotary-inertia turbine obtained through the design method for the low-rotary-inertia turbine, the high mechanical strength and the long life are achieved, the mass and the rotary inertia of the turbine are decreased, the low-speed responsiveness of a pressurizing system and the mechanical efficiency and reliability of a bearing system can be effectively improved, and then the pressurizer efficiency is improved; meanwhile, due to the fact that compared with the existing turbine, part of materials on the turbine back of the low-rotary-inertia turbine are removed, the integral uniformity of the turbine is improved.

Description

technical field [0001] The invention relates to the field of turbochargers, in particular to a low moment of inertia turbine design method. Background technique [0002] Since the beginning of this century, governments at home and abroad have successively raised the fuel consumption and exhaust emission standards of road vehicles and non-road vehicles in order to cope with global warming and oil crisis. The depletion of oil resources and the increasing emission standards have led many countries to guide the development of engines in the direction of small displacement and high power. With the development of low fuel consumption rate, turbocharging technology can improve vehicle engine power, reduce energy consumption and reduce emissions. This technology is currently one of the most effective means to achieve the goal of energy saving and emission reduction in the automotive industry and to improve engine efficiency. [0003] The turbine is one of the core components of the...
