摘   要

     本論文描述了GDC970/75對輥成型機的設計和計算過程，對成型機的結構和工作過程進行了分析,并對設計所用到的部件進行了校核。
隨著社會的發展，綠色環保是未來發展的方向，型煤以其具有粒度均勻，反應活性強，熱穩定性好，固硫消煙等特點，正逐漸被廣大用戶認可并接受利用，對輥成型機就是一種一種應用到型煤生產中的關鍵設備對輥成型機是由壓輥、軸承、給料系統、承壓支架、減速器（傳動裝置）、潤滑系統、等機構組成。與傳統低速重載、剛性不足的老式成型機相比，它具有體積小、重量輕、成本低廉等優點。
對輥組件直接關系到型煤煤球的成球質量，工業型煤是一種廣泛應用到冶金、制造化肥、電廠等工業領域、對節能、環保都具有重要意義的清潔、高效的新型燃料。本設計在對輥輥輪與對輥軸之間采用脹套無鍵連接技術，兩對對輥輥輪之間必須具有良好的對中性，否則會影響成型質量。采用脹套無鍵連接的優點是可以方便的松開脹套對輥輪進行調整，保證型煤的成球率。
根據成型機的結構和工作原理,對成型機的各組件進行了設計,設計的內容包括減速器、帶傳動、潤滑系統、承壓支架、壓輥、軸承.
本設計機架采用螺桿連接結構，此種機架制作簡便，而且承載能力強，拆裝方便，基本滿足大型對輥成型機的工作要求。

關鍵詞：對輥成型機；型煤；液壓加載

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.
