一种低搅油功率损耗的振冲器
本技术涉及振冲器设备领域,具体涉及一种低搅油功率损耗的振冲器。
技术介绍
振冲器的结构主要包括电机、联轴器、偏心结构三部分,工作原理是:通过电机带动振动体内安装偏心块的传动轴旋转,产生水平方向激振力,同时向振冲头压送高压物料,由振冲器头部射出,有助于提高地基改良效率。主轴与偏心块固定连接组合成偏心结构,目前振冲器主要采用半圆形偏心块,由两个以上的偏心块固定在轴上构成偏心结构,偏心块通常分为固定偏心块和活动偏心块。为了减小体积,增加压实效果,改进的技术方案为在偏心块内部设置铅块或密封水银等密度大的材料。为了快速带走旋转产生的大量热量,减小噪音,延长使用寿命,振冲器结构中往往需要将偏心结构布置在充满润滑油的油腔内,提高振冲器的工作性能。但是,上述机构中半圆形偏心块旋转会对周围润滑油进行搅动,造成电机功率浪费,形成搅油功率损失,腔内的涡流现象也会导致振冲器的不规则振动,影响其工作性能。改进的技术方案采用在原有的半圆形偏心块外周套设套筒,进一步的还可以为采用泡沫体积块填充多余的套筒空间,上述方案使得偏心件的外轮廓为圆柱形,但是上述结构会导致偏心 ...
