Abstract

As Chinese technology that is about construction machinery continues to improve, the power requirements of construction machinery is also increasing. the topic is about the design of the 6135 diesel engine overall structure, so that it can meet the needs of the power plant working for the project mechanical better.

The main subject of the relevant parameters of the 6135 Diesel to choose, to determine the effective power, fuel consumption rate. 6135 type of diesel engine thermodynamic calculation, the original parameters of the design of the model; from the dynamic calculation, design models of the maximum torque of the crank pin and main journal and draw the torque diagram to draw the crank pin of the pre-wear maps, boot hole so that the best place. Use of existing laboratory equipment and the effective parameters of modern engines and modern design references to the models to a series of effective improvements to make it the best design programs to meet the design. So that the models are better able to adapt to the needs of modern construction machinery .

By the models for computing and checking to determine the technical performance of the models. The general assembly drawings and part drawings are drawn to analyze the structural characteristics of the models to determine the design of the model improvements, and provide valuable theoretical reference for the design of similar products .

Keywords： 6135 diesel engine; Heat and power calculation; Checking calculation; Structural design
