Anti-bursting device for worm gear box of turbosupercharger

Abstract

The invention relates to an anti-bursting device for a worm gear box of a turbosupercharger. The anti-bursting device comprises an upper protective cover (1), a lower protective cover (2), heatproof stop screws (3) and the worm gear box (4) to be protected. The worm gear box (4) is provided with a first positioning platform (5), a second positioning platform (6), a third positioning platform (7) and a fourth positioning platform (8), which are adjustable in height and convenient for positioning connection. The upper protective cover (1) and the lower protective cover (2) are fixed on the four positioning platforms on the worm gear box (4) through the heatproof stop screws (3). The upper protective cover (1) is composed of a first upper side plate (9), a first top plate (10) and a first lower side plate (11). The lower protective cover (2) is composed of a second upper side plate (16), a second top plate (17) and a second lower side plate (18). The protective covers are in split structure, thereby being convenient to demount, replace and maintain.

Description

technical field [0001] The invention belongs to the technical field of turbomachinery, and in particular relates to an anti-explosion device for a turbine box of a turbocharger. Background technique [0002] Turbochargers are an essential part of modern engines to increase power, reduce fuel consumption and improve emissions. The turbocharger has been running at high speed for a long time. If the turbocharger breaks down due to failure, or even bursts, the flying debris will directly damage the surrounding objects, which is also a potential danger to equipment maintenance personnel. Due to the large mass of the turbine shaft of the turbocharger, the energy of the turbine impeller directly hitting the turbo box after flying is huge. Although the turbo box of the turbocharger has been designed inclusively, it is still possible to break down the turbo box under special conditions. The safety protection problem of the turbo box is particularly prominent, so we propose an anti-e...

Problems solved by technology

The turbocharger runs at high speed for a long time. If the turbocharger breaks down due to failure or even bursts, the flying debris will directly damage the surrounding objects, which is also a potential danger to equipment maintenance personnel.

Due to the large mass of the turbine shaft of the turbocharger, the energy of the turbine impeller directly hitting the turbo box after flying is huge. Although the turbo box of the turbocharger has been designed inclusively, it is still possible to break down the turbo box under special conditions. The safety protection problem of the turbo box is particularly prominent, so we propose an anti-explosion safety protection device for the turbo box of the turbocharger, which will effectively solve the safety protection problem when the turbocharger bursts

[0003] In order to meet the inclusive design of the turbo box, the wall thickness of the turbo box is usually very thick, resulting in a large mass of the turbo box, which is very inconvenient for the installation and disassembly of the turbocharger, component maintenance, etc., and also increases the Turbine box casting is difficult, and the yield is relatively low
