Marine turbocharger bearing housing with anti-rotation function

Abstract

A marine turbocharger bearing body with anti-rotation function comprises a bearing body, an anti-rotation device, an anti-rotation sleeve, a sealing cover plate and an elastic anti-rotation retaining ring. The anti-rotation device is installed in the anti-rotation device installation hole and the anti-rotation device limit hole on the bearing body, and the anti-rotation sleeve is installed in the anti-rotation device installation hole on the bearing body, and is set on the anti-rotation bracket of the anti-rotation device Top: The anti-rotation elastic open retaining ring is installed in the retaining ring groove on the inner wall of the anti-rotation device installation hole on the bearing body. The function of the anti-rotation elastic open retaining ring is to press the end face of the anti-rotation sleeve through its end face, and the anti-rotation sleeve The other end surface of the anti-rotation device is pressed against the anti-rotation device, so that the anti-rotation sleeve and the anti-rotation device are fixed on the corresponding positions of the bearing body; the sealing cover plate is installed on the port of the anti-rotation device installation hole on the bearing body through screws.

Description

technical field [0001] The invention relates to the technical field of turbochargers, in particular to a marine turbocharger bearing body with a rotation-stop function. Background technique [0002] Ships traveling in rivers, lakes, and seas will encounter harsh weather conditions, such as strong winds and waves. Therefore, marine engines must provide power for ships at all times, so that ships can effectively cope with strong winds and waves, prevent ships from being overturned by strong winds and waves, and ensure the safety of ships. . After the marine engine is changed from naturally aspirated to supercharged, the power is greatly enhanced. When the turbocharger of the marine engine equipped with the exhaust gas turbocharger breaks down, the engine is changed from supercharged to naturally aspirated. At this time, the engine can still send out more than 30% of the power to maintain normal work. In order to avoid more serious failures of the engine body due to the failu...

AI Technical Summary

Problems solved by technology

In order to avoid more serious failures of the engine body due to the failure of the supercharger when the engine is working continuously (for example, the oil leakage of the supercharger reduces the lubricating oil of the engine, the fragmentation of the impeller enters the engine cylinder with the airflow, etc., resulting in the engine not working
