The constant direction press type no-backlash gears with high performances was offered and an actual reduction gears with this method and the running tester for the gears were made and the experiments were done and the following results were obtained.1. On fundamental nature : in stational driving condition and giving the suitable value to the pressing force of the movable bearings, it is cleared that perfect no-backlash condition, high efficiency as 95% in full load and the higher rigidity more than ordinal single flank messing gears is achieved. Also the analyzing method of total performances of the mechanism from ones of each elements in the mechanism is developed.2. On transient vibration : the transient response and the frequency response are tested and it is cleared that the transient vibration is enoughly damped in the mechanism and the piled rubber type movable bearing is more effective than spring supported type one.3. On the stability of the control : The effect of the backlash to the stability of the control was experimentally tested and advantage of the offered no-backlash gears is conformed. Next, the theoretical analysis on the stability of the control on the mechanical system with backlash, hysteresis, stiffness and transmission error in gears was done using the approximated method with the discribing function and it is obtained that the hysteresis gives the worse effects than backlash to the stability of the control.As the result, it is concluded that to make the mechanism the more compact and to decrease the hysteresis from the mechanism should to be the important subjects for the next stage.

提出了高性能的恒向压式无侧隙齿轮，并利用该方法制作了实际的减速器和齿轮运行试验机，进行了实验，得到了以下结果。1.关于基本性质：在给定的传动条件下，通过对活动轴承压紧力的适当取值，可以获得理想的无侧隙状态，满负荷时效率可达95%，刚度比一般的单面啮合齿轮高。提出了从机构各组成部分的性能指标分析机构总体性能的方法.瞬态振动：通过瞬态响应和频率响应的测试，表明该机构对瞬态振动有足够的阻尼，且橡胶桩式动支座比弹簧支承式动支座有更好的减振效果.在控制稳定性方面：通过实验验证了齿侧间隙对控制稳定性的影响，验证了无齿侧间隙齿轮的优越性。其次，利用描述函数的近似方法，对具有齿隙、滞环、刚度和齿轮传动误差的机械系统的控制稳定性进行了理论分析，得出了滞环对控制稳定性的影响比齿隙更大，从而得出了滞环对控制稳定性的影响比齿隙对控制稳定性的影响更大的结论。因此，减小机构的滞后效应，使机构结构更加紧凑，应成为下一阶段的重要研究课题。
