不完全齿轮连杆式钳爪结构设计 摘要 不完全齿轮连杆式钳爪属于机械爪的一种，是一种非拟人类的机械手。节约人力和提高一些固定式工作的效率，是这类机械手的主要思想。随着科技时代的爆发，科技在人们的努力下飞速发展，机械爪已经普遍的出现与使用在人们的生活中。在一些特定的环境与人们无法工作的环境中，机械爪能够承载起那些人们无法承载的的环境进行工作，机械爪在一些事情面前有着它天然的优势。 本文通过一些简单的零件，以一个微型减速电机产生动力，利用齿轮传动的精密性与稳定性，还有连杆在传动机构的重要地位，设计出了一款简单的机械钳爪。机械钳爪能够完成我们设计的简单运转，或许能够参与一些简单的工作。 不完全齿轮连杆式钳爪的设计说明了，机械爪相对于人们的一些优势，他能在一些事情中代替人们的工作，机械爪在工作中对于人体来说有着显着的优势，还有在不远的未来机械爪所带来的巨大展望。 关键词：不完全；机器手；钳爪 Abstract The i
