摘　　要：针对弹子加压装置,设计实现了测量其接触副力传递效率的试验机,介绍了该试验机的结构和原理.并采用所研制的试验机测量了几种典型的弹子盘试样的力传递效率,利用试验测量结果分析了影响力传递效率的因素.试验结果表明:随着载荷增加,各种弹子盘与弹子接触副的力传递效率都有所下降;当移动盘输出推力较低时,弹子盘的材料(38CrSi和GCr15)对力传递效率影响较小;当载荷增加时,GCr15的弹子盘的力传递效率下降幅度比38CrSi的小;弹子槽倾角α=25°的弹子盘试样的力传递效率较弹子槽倾角α=15°的力传递效率总体偏低.In this paper, a testing machine for marble-marbles disk pressure mechanism is designed and manufactured to measure the force transmission efficiency in the contact pairs of marble and marbles disk. The structure and principles of the testing machine are introduced, and the force transmission efficiency of several typical marble disk specimens is measured by the testing machine. Using the measurement results, the factors that influence the transmission efficiency are analyzed. The results showed that, as the load increases, the force transmission efficiency in the contact pairs of various marbles disks declines; when the load is small, the force transmission efficiency is less affected by the material of marbles disk （38CrSi and GCr15 ） ; as the load increases, the decline of the force transmission efficiency of GCr15 marbles disk is smaller than 38CrSi marbles disk; the force transmission efficiency of marbles disk specimen whose marbles disk slot angle is α = 25° is generally lower, compared with marbles disk specimen whose marbles disk slot angle is α = 15°.
