PEF600X900复摆颚式破碎机动颚结构设计
摘要
颚式破碎机在工矿企业被广泛的应用,这是因为该机构结构简单、机型齐全并已大型化。颚式破碎机经过100多年的实践和不断改进,其机构已日臻完善,随着社会的发展需求破碎的要求不断提高,对产品和产品的质量也大大的提高了,破碎机的机型已经发展到很多种了。
本文主要是对复摆颚式破碎机设计研究。复摆颚式破碎机是因为其动颚在其它机件的带动下作复杂的一般平面运动而得名,其动颚上的轨迹一般为封闭曲线。复摆破碎机由于偏心轴负荷大一般制成中型和小型的,其破碎比可达10。复摆颚式破碎机在工作时偏心轴作逆时针旋转,对所装入的物料有向下退并夹持作用。该机型垂直摆幅下大上小,有利于出料口处动颚将成品推出。由于整块动颚作复杂运动因此对物料块不但起挤压、劈裂、弯折作用,还能起碾搓作用,故可破碎稍微粘湿的物料。采用正支撑复摆颚式破碎机,动颚下部的特性值m很大,使得动颚和定颚的衬板磨损很快,但却具有较高的生产能力。由实际生产说明,正支撑式颚式破碎机的结构形式具有动颚轨迹分布合理、生产能力高、结构更简单等优点,使其得到广泛应用。

ABSTRACT
Palate crusher in the industrial and mining enterprises were widely used, this is because the body structure is simple, plete and large-scale models of. Palate crusher after 100 years of practice and continue to improve, their bodies have been improving,with the social development needs of the requirements broken constantly improve the products and the quality of the products have greatly improved, the crusher models have been developed to a variety .
This paper is pound pendulum palate crusher design study. Compound pendulum palate crusher because of its dynamic palate in other parts of the lead plane for the general plex named after. Moved palate its trajectory is generally closed curve. Crushing machine-placed eccentric axle load due to the generally made of medium-sized and small, broken up over pound pendulum palate crusher at work for the eccentric shaft counterclockwise rotation, the load of materials and a retreat clamping downward effect. The models under a vertical swing on small and is conducive to moving the material I will be refined palate launched. As block palate plex dynamic movement of materials therefore not only blocks from the extrusion, Split, bending role, but also from the roller rubbing role, it can be slightly broken stick wet materials. Support is facing plex palate crusher, moving the lower part of the palate of great val
