摘要
EBZ125XK型掘进机是一种悬臂式掘进机，主要用于中型煤巷及半煤岩巷的掘进作业。它结构紧凑、适应性好、机身矮、重心低、操作简单、检修方便。本设计主要针对掘进机的整机进行方案设计，对截割部进行结构及传动等相关设计。EBZ125XK型掘进机截割部驱动动力由截割电机提供，为实现较强的连续过载能力，适应复杂多变的截割载荷，并利用喷雾水加强冷却效果，悬臂式掘进机多采用防爆水冷式电动机来驱动截割头。在截割部传动设计中用2K-H行星减速器。设计中对2K-H型行星减速器进行了优化配齿，采用高度变位，并做了相应的校核。

ABSTRACT
The medium-size EBZ125XK type tunnelling road-header is mainly used in tunnelling operations of the medium coal lane and the half coal crag lane digging the tunnels,.It marks by features of compact construction , good adaptability, a short body and a low center of gravity ,it is also easy to operate and convenient to overhaul. This paper is mainly make a design for the overall machine and something else relevant to the structure and transmission of the cutting unit.The cutting unit driving force of EBZ125XK is provided by the cutting motor。Tunneling road-header normally adopt explosion-proof water-cooled electric motors to drive the cutting head, using water spray to strengthen the cooling effect, for improve the ability of continuous overloading and adapt to the complex and volatile cutting load. Based on the theory of 2K-H type planetary reducer, this paper design a appropriate 2K-H type planetary reducer which can be use in cutting unit. The design of 2K-H type planetary reducer has optimize the selective gear.
Keywords：Cantilever tunneling machine ；cutting unit ；Planet reduction gear
