Abstract

Disclosed is a gear chamber structure of an internal combustion engine. The gear chamber is constituted by, fixedly connected in a descending sequence, an upper cover (11), a gear support frame (8), and a lower cover (13). The gear support frame is an overall box-shaped structure having a front wall (8a), a rear wall (8b), a left wall (8c), and a right wall (8d). An idler gear having a large module is arranged within the gear support frame. An output port is arranged on an external wall face of the overall gear support frame. This implements for the internal combustion engine auxiliary output of multiple ports and of high-power. The overall box-shaped structure of the gear support frame and the trisection split-body-type gear chamber structure having upper-, middle-, and lower-sections improve the stiffness of the gear chamber. The gear chamber structure reduces difficulties in assembly and manufacturing, and allows for convenient maintenance operation.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to a gear chamber structure of the internal combustion engine, and belongs to the technical field of power devices. Background technique [0002] The gear chamber structure of internal-combustion engine is well-known all the time, generally adopts up and down integral body, front and back split, and gear is installed and supported and is connected in the middle of front and back cover with bolt. The overall rigidity of the gear chamber with this structure is poor, the output ports are few, and the water channel and the oil channel must be arranged with open pipes. The overall structure is complex and not compact, and it cannot meet the requirements of high-power auxiliary output. Contents of the invention [0003] The present invention aims at the deficiencies of the above-mentioned prior art, and provides a gear chamber structure of an internal combustion engine, which improves th...
