摘　　要：机械基础作为机电与机制专业的专业基础课,是学习机械原理等后续课程的基础,对机械基础课中疑难点的透彻理解,会对后续课程的学习起到事半功倍的效果,由此特对机械基础学习中受力分析、铰链四杆机构、螺旋传动、蜗杆传动等疑难点加以剖析。As the basic course of electromechanical and mechanism major, mechanical foundation is the basis of studying mechanical principles and other follow-up courses. Therefore, the force analysis, hinge four-bar mechanism,spiral transmission, worm transmission and other difficult points in mechanical basic learning are analyzed. Through a thorough understanding of the difficult points in mechanical basic courses, the follow-up courses will have twice the result with half the effort.
