Protective type engine cylinder shell

Abstract

The invention discloses a protective type engine cylinder shell. The protective type engine cylinder shell comprises a lower shell, a middle shell is arranged on the upper side of the lower shell, andan upper shell is arranged on the upper side of the middle shell. A sealing mechanism is disposed at a joint of the lower shell and the middle shell, and the sealing mechanism includes a sealing raised line, a sealing groove, a heat-resistant sealing ring, push plates and springs. The sealing raised line is fixedly mounted on the lower side of the middle shell, the sealing groove is formed in theupper side of the lower shell, and the position of the sealing groove corresponds to the position of the sealing raised line. The heat-resistant sealing ring is installed in the sealing groove, the push plates are installed in the heat-resistant sealing ring, and the springs are fixedly mounted on one sides of the push plates. Through the sealing mechanism designed between the shells, sealing canbe performed by the sealing mechanism when connection is performed, the edge of the seal ring is convexly and closely attached into the sealing groove by tightly pressing the push plates by the sealing raised line during sealing, and a sealant is injected for auxiliary sealing, so that the phenomenon of air leakage due to poor sealing after long time use is prevented.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a protective engine cylinder casing. Background technique [0002] The engine cylinder housing is the skeleton of the engine and the installation basis of the various mechanisms and systems of the engine. All the main parts and accessories of the engine are installed inside and outside, and bear various loads. Therefore, the body must have sufficient strength and rigidity. The main function of the engine cooling system is to dissipate part of the heat absorbed by the heated parts in time to ensure that the engine works at the most suitable temperature state. The cooling system can be divided into air-cooled and water-cooled according to different cooling media. If the heat of high-temperature parts in the engine is directly scattered into the atmosphere for cooling, it is called an air-cooled system. The device that transfers the heat to the cooling water first, and...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a protective engine cylinder housing, to solve the problem that the existing protective engine cylinder housing proposed in the above-mentioned background technology is used because the joint of the engine cylinder housing is usually sealed with sealant. Sealed, there will be small air leakage problems due to long-term use and vibration
