【摘要】 设计了一种齿轮—连杆二级放大手动压力机。该机构采用齿轮与连杆串联组合的方式进行增力,介绍了压力机各机构之间运动的传递及力放大原理,给出了力放大倍数的计算公式。该压力机具有结构紧凑,使用方便,其特点在于手柄可以实现360°连续旋转,而且压头在下压过程中输出压力会越来越大。更多还原

【Abstract】 A symmetric gear-toggle manual press which could amplify force twice was designed.It is designed by use of gear transmission and toggle mechanism combined in series.This paper introduced the working principle of the press,and gave the computational formula of its magnification.The press′s structure is simple,and operation is convenient,etc..The press′s characteristic are its hand shank can rotate 360 degree,and as the press cake move down the output increases,and also actual examples are used to illustrate the formula.更多还原
