摘 要本设计主要介绍了锯齿状塑料破碎机的发展历史、工作原理和设计过程。基于对塑料炭行业的分析和近期塑料炭行业的背景，以及锯齿塑料破碎机存在的问题和不足，我们制定了塑料炭行业的使用方案设计。本设计采用单电机驱动方式，电机轴接皮带传动，大皮带轮接单级减速机输入轴。减速机的输出轴与主动齿轮滚轴连接，扭矩通过同步齿轮传动传递到从动齿轮滚轴。本次设计的主要设计内容包括单级减速机、皮带传动、一对同步齿轮、齿辊盘和齿辊轴的设计。由于整个传动系统比较简单，保证了传动的稳定性。考虑到牙科塑料研磨机存在的一些问题，本次设计还增加了一些改进措施。磨盘上装有磨锥，以提高磨辊齿的磨削效果，减少粉尘过多的现象。装有弹簧回缩安全装置，能很好地补偿散状物料进入破碎箱时齿辊的位移，防止破碎辊被铁屑损坏。关键词：齿式；破碎机；齿辊；塑料破碎机 ；减速器ABSTRACTThis design mainly introduces the development history, working principle and design process of the zigzag plastic crusher. Based on the analysis of the coal industry and the recent background of the coal industry, and the problems and deficiencies of the sawtooth plastic crusher, we have formulated the use plan design of the coal industry.The design adopts single motor drive mode, motor shaft to belt drive, large pulley to single stage reducer input shaft. The output shaft of the reducer is connected to the active gear roller, and the torque is passed through the synchronous gear drive to the driven gear roller. The main design contents of this design include a single-stage reducer, belt drive, a pair of synchronous gear, tooth roller disc and tooth roller shaft design. Because the whole transmission system is relatively simple, the transmission stability is guaranteed. Considering some problems with the dental plastic grinder, some improvements were added to this design. The grinding plate is equipped with a grinding cone to improve the grinding effect and reduce excessive dust. The spring retraction safety device can well compensate for the displacement of the tooth roll when the scattered material enters the crushing box to prevent the broken roll from being damaged by iron chips.Key words: tooth type; crusher; tooth roller; plastic crusher; speed reducer目 录摘 要 IABSTRACT II1 绪论 11.1选题背景及意义 11.2齿辊式破碎机的发展 21.2.1国内齿辊破碎机的发展 21.2.2国外的齿辊式破碎机 41.3齿式塑料破碎机的工作原理及使用中的问题及改进 51.3.1工作原理 51.3.2齿式塑料破碎机存在的问题 61.3.3改进措施 61.4本设计的主要内容 72 总体设计 82.1方案设计 82.2工作参数的确定 92.2.1破碎机的技术参数 92.2.2其他参数计算 92.3传动和减速系统的确定 122.3.1总传动比及传动比分配 122.3.2传动装置的运动参数的计算 133 传动系统设计计算 153.1 带传动设计计算 153.2减速器设计 173.2.1齿轮传动设计 173.2.2轴结构设计 203.2.3轴承校核 263.2.4键的选择与校核 283.2.5减速器铸造箱体的主要结构尺寸设计 293.3同步齿轮设计 313.4破碎齿辊箱设计 343.4.1齿辊的结构的设计即破碎齿盘设计 343.4.2齿辊切向力计算 363.4.3齿辊轴设计 383.5调整与保险装置 41结 论 42参考文献 43致 谢 45
