双齿辊破碎机说明书

摘 要

本设计主要介绍了双齿辊破碎机的发展历史、组成及工作原理，在分析煤炭工业及煤炭工业的行业背景的基础上，了解了现代双齿辊破碎机在煤矿行业应用时主要存在的技术问题和不足。根据这些问题和不足之出发而设计了本双齿辊破碎机。

本设计首先确定了设计方案，主要采用带传动加二级圆柱齿轮减速器减速，由于传动系统简单，这就保证了传动的稳定性，同时在破碎辊齿方面也进行了改进，在破碎盘上加装了破碎锥，所以破碎效果更好，不会产生过粉尘现象，其次就是加装了一套退让装置，退让装置是由弹簧和齿轮桥机构组成的，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。

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
