一种新型实用的双斜楔面-圆柱滚子二次增力机构

One New Applied Mechanism Based on Two-Steps Force Amplifier Composed of Roll-Body and Double Inclines

通过对圆柱滚子的运动受力分析,推算出机构的增力倍数的力学计算公式.并对原有机构进行改进,用滚动摩擦代替滑动摩擦,大大地减小摩擦力对增力机构工作的影响,保证增力机构能得到高倍率的力放大输出.该机构具有较强的实际使用价值.

By analysis of force acting on the roll body, we get the equation of enlargement of force enlargement mechanism. By adding a roll body, therefore the rolling friction substitute sliding friction that is in the custom mechanism. The influence of friction in the proposed structure is minimized, therefore make it possible that force enlargement mechanism obtain great enlargement of forces. The mechanism has potential application in practice.
