Marine turbocharger bearing body with rotation stopping function

Abstract

The invention provides a marine turbocharger bearing body with a rotation stopping function. The marine turbocharger bearing body comprises a bearing body, a rotation stopping device, a rotation stopping sleeve, a sealing cover plate and a rotation stopping elastic split retainer ring. The rotation stopping device is mounted in a first rotation stopping device mounting hole and a second rotation stopping device mounting hole on the bearing body; the rotation stopping sleeve is mounted in the first rotation stopping device mounting hole on the bearing body and is sleeved on a rotation stopping bracket of the rotation stopping device; the rotation stopping elastic split retainer ring is mounted in a retainer ring groove on the inner wall of the first rotation stopping device mounting hole; the rotation stopping elastic split retainer ring has the effect that the end face of the rotation stopping sleeve is tightly pressed by the end face of the rotation stopping elastic split retainer ring, and the other end face of the rotation stopping sleeve is used for tightly pressing the rotation stopping device, so that the rotation stopping sleeve and the rotation stopping device are fixedly arranged on the corresponding positions of the bearing body; the sealing cover plate is mounted on an opening of the first rotation stopping device mounting hole on the bearing body by a screw.

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
