摘   要

     本范文描述了GDC970/75对辊成型机的设计和计算过程，对成型机的结构和工作过程进行了分析,并对设计所用到的部件进行了校核。
随着社会的发展，绿色环保是未来发展的方向，型煤以其具有粒度均匀，反应活性强，热稳定性好，固硫消烟等特点，正逐渐被广大用户认可并接受利用，对辊成型机就是一种一种应用到型煤生产中的关键设备对辊成型机是由压辊、轴承、给料系统、承压支架、减速器（传动装置）、润滑系统、等机构组成。与传统低速重载、刚性不足的老式成型机相比，它具有体积小、重量轻、成本低廉等优点。
对辊组件直接关系到型煤煤球的成球质量，工业型煤是一种广泛应用到冶金、制造化肥、电厂等工业领域、对节能、环保都具有重要意义的清洁、高效的新型燃料。本设计在对辊辊轮与对辊轴之间采用胀套无键连接技术，两对对辊辊轮之间必须具有良好的对中性，否则会影响成型质量。采用胀套无键连接的优点是可以方便的松开胀套对辊轮进行调整，保证型煤的成球率。
根据成型机的结构和工作原理,对成型机的各组件进行了设计,设计的内容包括减速器、带传动、润滑系统、承压支架、压辊、轴承.
本设计机架采用螺杆连接结构，此种机架制作简便，而且承载能力强，拆装方便，基本满足大型对辊成型机的工作要求。

ABSTRACT
This paper describes the design and calculation process of the GDC970/75 roll forming machine , forming machine structure and working process of analysis and design of the components used in the check.
With the development of society, green is the future development direction of its briquette with uniform particle size and reactivity strong, good thermal stability and Smoke desulfurization characteristics of the majority is being recognized and accepted by users.
Industry roll-type forming machine is a crucial device applied to the manufacturing of shape-coal. It’s a kind of engineering machine. Roll-type machine consists of units such as pressing rolls, bearing, feeding system, bearing beam ,three-staged velocity-reduction gearbox (transmission system), lubricating system, and hydraulic pressing system, etc .compared conventional forming machine ,with heavy-burden and inadequate rigidity, it is of small-volume,;low-weight and low-cost.
Double rolls have a direct relation to the forming-quality of shape-coal. Industry shape-coal is a new-type of clean ,effective fuel which is widely applied to various industry field such as metallurgical industry ,manufacturing industry chemical fertilizer, calcium carbide and has a vital significance to energys-aving and environment-protection business.
Design in the paper uses expanded–casing and no-key connecting technology and it must be guaranteed that it must be of good centering character-
istic betwween ball groves of the two rolls. Otherwise the forming quality will be
seriously affected. Use expanded-casing and no-key connecting technology, rolls can can be conveniently adjusted by loosning expanded-casing to ensure the forming rate of shape coal.
    According to the molding machine structure and working principle of forming machine components of the design, including the design of reducer, Belt Drive, lubrication system, confined stent, pressure roller bearings
Design of structure uses construction of pressing rolls which can be easily removed or easily altered. This kind of structure is of simple-make and bear heavy loads. Hence,the working requirements os large scale roll-type forming maching are satisfied.
Keywords: roll-rype forming machine; shape-coal; hydraulic loading.
