1、 题目： 破碎机的结构及工作原理研究题目： 破碎机的结构及工作原理研究 班班 级：级： 姓姓 名：名： 专专 业：业： 指导教师：指导教师： 答辩日期：答辩日期： 摘摘 要要 破碎机是冶金、化工、矿山、电力、陶瓷、水泥、建筑和筑路等工业部门广泛应用 的主要设备，每年有大量的原料和再利用的废料都需要进行粉碎处理。现就题目要求设 计有关石灰石的反击式破碎机。综合考虑，本次设计选择单转子反击式破碎机，可针对 不同的破碎粒度进行反击破碎。 本次设计的原型为 PF0807 型反击式破碎机。在设计过程中，根据最大给料粒度设 定转子直径和转子长度，由此初步设计转子轴，并根据转子转速和直径等参数校验转子 是否

2、满足弯扭强度要求。其次对破碎腔进行设计，主要设计一、二级反击板。设计时既 要考虑让反击面尽可能的接近转子外圆的渐开线方程，又要符合反击板实际的制造情 况。当反击板的位置确定后，破碎腔里其它零部件的设计参数和尺寸就基本确定了。再 根据转子的转速和破碎腔的结构计算破碎机的生产率并选择合适的电机，最终完成破碎 机的结构设计。 关键词关键词：破碎 破碎腔 转子 反击板 Abstract Impact crushers are applied to such each department as the cement plant , power plant ,etc. in a large amount

3、, so its design has an extensive prospect and experience that can be used for reference. Its design essence is, formerly after total conceptual design, a design which points each main spare part , question of installing and making a reservation etc., and carry on the intensity to check and test to t

4、he specific part, and in relevant thematic parts, analysis of comparing question that the life-span of very beginning of the hammer lengthens in detail . In the design of each spare part , should include the choice , sureness , demand processed , structure craft satisfication of the size of the mate

5、rial , and the demand for cooperating with other parts, etc When the intensity is checked , should use relevant formulae , carry on the analysis of the dangerous position, need to check form , mapping , calculation ,etc Then to to install , work course , work situation after predict that carries on

6、more overall inspection whole, give consideration to the question in such respects as maintaining and safety ,etc. at the same time . Finally , choose to analyse in machining accuracy , public errand to two groundwork parts, economy and dependability that the breaker soed as to ensure is designed finally.
