设计简介
摘要：破碎机械设备，属于矿山机械范畴。这这类机械设备在冶金、建材、化工、能源、交通建设、城市建设和环保等诸多领域有广泛的用途。简摆一般制成大型和中型的，复摆一般制成中型和小型的。简摆破碎机可以产生很大的破碎力，这是复摆破碎机所不能能、低能耗的新型颚式破碎机，从而大大提高了破碎机的性能，缩短了产品开比的，故在大型破碎机中一般用这种结构，复摆腭式破碎机的生产能力高于简摆腭式破碎机约30%，同时也因为过大的垂直行程，使得定、动腭衬板（齿板）磨损很快，大大降低了使用寿命。我国自50年代生产腭式破碎机以来，在破碎机设计方面经历了类比、仿制、图解法设计阶段，目前正向计算机辅助设计阶段过渡。国外从上世纪中后期开始利用计算机仿真技术对颚式破碎机机构、腔型、产量和磨损等进行优化，高性发周期，提高了产品的市场竞争力。
本文中所设计PEJ900X1200简摆颚式破碎机的设计要求为：破碎机偏心轴偏心距为25mm，连杆长度为1325mm左右，破碎腔设计为900×1200mm，破碎腔啮角20度，传动角为45～55度，动颚上端厚度为316mm，肘板长度为300～400mm，破碎机悬挂高度为100～160mm。腭式破碎机动颚水平行破碎腔啮角的大小直接关系到物料的受力状态，机架结构设计和破碎机产量，小的啮角有利于提高破碎机产量，利用先进破碎原理进行物料破碎，但破碎机高度将增加。所以根据经验值，本设计采用的啮角为20度。

That such machinery and equipment in metallurgy, building materials, chemicals, energy, transportation, urban construction and environmental protection, and many other fields have a wide range of uses. Pendulum the type breaker put into large and medium-general, made of medium-sized compound pendulum general and small. Pendulum the type breaker can produce great breaking force, which is facing complex than can not be broken by the machine, so the large breakers in general with such a structure, the compound pendulum palate crusher capacity than simple pendulum palate crusher - About 30 per cent, but also because of too great a vertical journey, making set, moving the palate liner (tooth plate) and wear very quickly and greatly reduce the service life.Our country since the 50's productions Oral cavitytype breaker, hasexperienced analogy, the imitation, the graphic method design stage inthe breaker design aspect,At present to computer-aided design stage transition.

In this article designs PEJ900X1200 Pendulum the type breaker thedesign request is:The breaker eccentric shaft distance is 25mm, the connecting rodlength is about 1325mm, the broken cavity design is 900×1200mm,The broken cavity gnaws angle 20, the transmission angle is 45~55,moves the jaw upper extreme thickness is 316mm, The wrist plate length is 300~400mm, the breaker is hanging highly is100~160mm.Designs small the jaw type broken mobile jaw horizontal travellingschedule to have the use to reduce static, moves Board the attrition,improves the breaker stress,Lengthens board the service life. The broken cavity gnaws the anglethe size directly to relate the material the stressful condition, therack structural design and the breaker output, small gnaws the angleto be advantageous to enhances the breaker output,Uses the advanced broken principle to carry on the material brokenly,but the breaker highly will increase.
