Abstract：Broken mechanical equipment, areas of mining machinery. 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. The productionmanufacture At present to computer-aided design stage transition. The productionmanufacture Oral cavit the type breaker more and more big, the performancemore and more good, the variety are more and more many, and in oninternational holds the certain market. the type breaker more and more big, the performancemore and more good, the variety are more and more many, and in oninternational holds the certain market.
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.
