620×900复摆颚式破碎机
摘 要
复摆式颚式破碎机与简摆式相比较，其优点是：质量较轻，构件较少，结构更紧凑，破碎腔内充满程度较好，所装物料块受到均匀破碎，加以动颚下端强制性推出成品卸料，故生产率较高。
本设计需求参数为进料口尺寸：620×900mm；最大进料粒度：340mm；偏心轴转速：275r/min；排料口调整范围：40～100mm；电动机功率：30KW。设计分析了破碎机的发展现状和研究颚式破碎机的意义及复摆颚式破碎机机构尺寸对破碎性能的影响，设计内容主要包括复摆颚式破碎机的动颚、偏心轴、皮带轮、动颚齿板、定颚齿板、机架等一些重要部件；另外，对颚式破碎机的工作原理及特点和主要部件的作用作了介绍，包括保险装置、调整装置、机架结构、润滑装置等。

620×900 Jaw crusher
ABSTRACT
Compared with fine impact crusher ，SBM（swinging jaw break machine）′s advantage is: quality is lighter, less compact structure component, broken lumen filled with degree is good, with materials by uniform broken, to block bottom mandatory move jaw is unloading, launch finished higher.
This design is done for：the feeding port size is 400 x 600mm; Maximum feeding granularity is 340mm; Eccentric shaft speed is 275r/min; Discharging mouth adjustment range 40mm to 100mm; Motor power is30 KW. This design analysis of the current development of the crusher， the meanings of researching the crusher, how the dimensions of jaw crusher effect on the performance of the broken, the design content mainly includes swing jaw, eccentric shaft, pulley, seeing jaw gear plate, and settled jaw gear plate and frame and some other important components; In addition, jaw crusher principle and characteristics and main component function is introduced, including insurance device, adjusting devices and frame structure, lubrication device.
KEY WORDS: Jaw crusher, Belt drive, Flywheel, Wear
