摘  要

本设计主要介绍双齿辊破碎机的发展史、工作原理及其设计过程，在分析了近年来煤炭工业及煤炭行业背景以及双齿辊破碎机在煤炭行业使用过程中的问题和不足的基础上制定方案进行的设计。

本设计采用单电机拖动方式，电机轴连接带传动然后再由大带轮与单级减速器的输入轴相连。减速器输出轴与主动齿辊轴相连，再通过同步齿轮传动将转矩传递到从动齿辊轴。本设计主要设计内容包括一个单级减速器、带传动、一对同步齿轮和齿辊盘及齿辊轴的设计。由于整个传动系统比较简单，保证了传动的稳定性。针对现在双齿辊破碎机所存在的一些问题，本设计还添加了一些改进措施。在破碎盘上加装了破碎锥，使得破碎辊齿的破碎效果更好并减少了过粉尘现象。加装弹簧退让保险装置，这样就可以很好的补偿大块物料进入破碎箱时齿辊产生的位移，防止破碎辊发生过铁损坏。

ABSTRACT

This design introduces a pair of teeth roll crusher history, composition and working principle of the coal industry and coal industry, based on industry background, understanding of the modern double-toothed roll crusher in coal industry, primarily in the technology application problems and shortcomings based on these problems and deficiencies of this proceeding designed to double teeth roll crusher.

The design of the first set design, with belt drive plus two main gear reducer, as a simple drive system, which ensures the stability of transmission, while the broken tooth roller also made improvements in the broken plate installation of the crushing cone, so broken better, will not produce the phenomenon of excessive dust, followed by installation of a concession equipment, concession equipment and gear by the spring bridge institutions, so that compensation can be a good chunk material into the crushing box displacement generated when Roll.

Key words: Double teeth roll crusher; Roll; Crusher
