曲柄压力机的压力能力、扭矩能力与力-转角曲线图的关系分析

Relation Analysis of the Pressure Ability,Torque Ability of Crank Press and Force-angle Curve

介绍了曲柄压力机的压力能力、扭矩能力的计算方法,并通过对JA21-18型曲柄压力机的能力分析计算,得出此种压力机两方面能力分别与力-转角曲线图的关系。在选用压力机时,必须严格按照许用负荷曲线图来选择。

The count method of the pressure ability and torque ability of crank press has been introduced with the relation of the two kinds ability of the crank press and force-angle curve gained by analyzing and computing the data of JA21-18 crank press ability.It is shown that permitted load curve must be implemented in choosing crank press.
