毕业设计论文题 目：双齿辊破裂机的设计摘 要国目前原煤的破裂一般采纳锤式破裂机或齿辊式破裂机。锤式破裂机是以高速运动的锤头打击物料，在破裂腔受到相互破裂冲击和剪切。齿辊式破裂机是在齿的作用下对物料进行劈碎，破裂后的物料直接排出，因此破裂粒度比较均匀。目前的双齿辊破裂机由于整体结构的不合理和破裂齿磨损快不能修复等原因，使用效果大大降低甚至很差。我所设计的新型双齿辊破裂机是在吸取国外先进技术的基础上研制和设计出来的破裂机，很有进展前景和市场前景。通过资料收集、整理和设计，我设计的双齿辊破裂机完成了。通过对资料的搜集、查找，我找到了很多对设计有用的参考资料，从而保证了设计的顺利进行。这次设计是对我大学四年所学知识的一次综合检验和全面总结。在这个过程中我学会了独立思考、在实践中找答案、在前人的基础上求创新。关键词:双齿辊破裂机；齿轮；轴Abstract Domestic current coal is broken generally using hammer breakers or toothed roll breakers. Hammer breakers is based on the high speed movement of the hammer and blow materials which is broken by impact and shear in crushing cavity.Toothed roll breakers chop materials by teeth action,then immediatly output.So its particle is well-distributed.Current toothed roll breakers is very bad in using effects because the whole structure is unreasonable and teeth is wearing out very fast. New double toothed roll breakers which is designed by me absorb developed technology which is developed and designed as breakers.It has a bright vista in development and maket.Double toothed roll breaker which I designed is complete by collect and tidy data.I found many useful information through find and collect and guarantee the developing of design.This design is a composite test for my university knowledge.I learnt think by myself found answer in practice and created something new based on former.Key words:double toothed breaker ； Gear ；Axis 目录1 绪 论 12 总 体 设 计 方 案 22.1 设计特点...
