Design of cutting part of boring machine

Abstract With the rapid development of the coal industry in the world, the world has put forward higher requirements for the coal mining machinery. Tunneling machine is the main machinery and equipment of coal mining. The advanced or not determines the speed and quality of coal mining, and then affect the economic benefits of coal industry. Therefore, it is very important to design an advanced boring machine for coal mining industry.

Cutting department is an important equipment in the coal mining of the boring machine, the quality of the equipment is good or bad, the length of life directly affects the ratio of the boring machine. This paper is mainly aimed at the cutting part of the boring machine to carry on the reasonable design, the reference is the cutting part of the EBZ-125 type. First of all, this paper summarizes the development history and the future development trend of the tunneling machine, and expounds various kinds of boring machines. Then the general interpretation of the various components of the EBZ-125 type boring machine. Then it introduces the components of the cutting part of the tunneling machine and the materials used in this paper. The selection of gear material, the selection of gear parameters and the strength check of 2K-H type gear reducer are described in detail.
