为进一步检验精密谐波齿轮的柔轮对其整体输出扭转刚度的影响,设计了一套谐波齿轮柔轮扭转刚度测试系统。谐波齿轮柔轮扣在模拟波发生器上,用外卡具夹紧固定柔轮外齿,使其处于工作变形状态,采用双向力偶的形式通过力矩盘在其输出端施加双向渐变力矩,利用光学自准直仪精确测量柔轮转动的角度,从而计算出被测柔轮的扭转刚度。完成了某精密谐波齿轮柔轮的扭转刚度测量,测试结果表明被测柔轮扭转刚度高达27 000 N°m/rad,不是谐波齿轮整体输出刚度不足的薄弱环节。
In order to further test the influence of the flexspline of the precision harmonic gear on its output torsional stiffness, a torsion stiffness test system of harmonic gear flexspline was designed. Harmonic gear soft buckle buckle in the analog wave generator, with the external clamp clamping flexo external teeth, making it in the work of deformation, the use of two-way force in the form of dual-phase torque through the torque plate at its output, the use of Optical autocollimator accurately measure the angle of rotation of the flexspline to calculate the measured torsional stiffness of the flexspline. The torsional stiffness measurement of a precision harmonic gear flexible wheel is completed. The test results show that torsional stiffness of the tested flexible wheel is up to 27 000 N ° m / rad, which is not the weak link of the overall output stiffness of the harmonic gear.
