    摘要： An instantaneous torque determining apparatus for obtaining the instantaneous torque value continuously of a shaft rotating at a high speed. The apparatus includes a pair of spaced gears mounted on the shaft, a torque detector having a pickup for each gear, a set of voltage comparators, a gate control circuit, an AND circuit, and a clock pulse generator. Further, the apparatus also includes a delay circuit for receiving pulses from a voltage comparator, a subtraction counter which receives a delayed pulse as a subtractor starting instruction, and a set of first and second ratio multipliers forming a counting circuit loop with the counter. First and second latch circuits store the counted value outputs and apply such outputs as an input to another counter and to a Digital-Analogue transducer. The pick-ups of the torque detectors are respectively arranged to face the gear to provide voltage signals in pulse form when the shaft rotates and each tooth of the gear passes in front of its respective pick-up. The phase difference in each period of the voltage signals is proportional to the instantaneous value of torque applied to the shaft and an inverse value of the period of these voltage signals is proportional to the instantaneous rotating speed of the shaft.

    摘要： An angle transducer which photo-electrically measures the rotation angle of a shaft by utilizing, a polarizer disc is arranged as follows: the polarizer disc is secured to the shaft to be measured or to the detection shaft of the angle transducer. Two pairs of photo-electric conversion elements are in opposition to light sources across the polarizer disc. The first and second polarizer plates are interposed between the photo-electric conversion elements of each pair. The transmission axes of the first and second polarizer plates differ from each other by 45 degrees. The quantities of light emitted by the light sources or the outputs of the photo-electric conversion elements are modulated by carrier waves of two phases differing 90 degrees from each other. The amplitudes of the outputs correspond to the sine and cosine functions of the double angle of the rotation angle of the shaft to be measured. These outputs form modulated waves of two phases differing 90 degrees from each other. The sum of the modulated waves of two phases, and the difference between the sum and a signal obtained by multiplication of the two phase carrier waves by a predetermined value, are computed by addition and subtraction computers to obtain a phase signal of a sine wave the phase of which is proportional to the rotation angle of the shaft being measured.

    摘要： The present invention relates to a gear mesh testing instrument in which the transmission error occurring between the two gears to be tested (the driving gear and the driven gear) is measured while both gears are rotating while intermeshed with each other. A pulse generator is connected to the rotating shaft of the driving gear, and of the driven gear, respectively, so as to produce two pulse signals having frequencies proportional to the number of the rotation of the gears. Then, the two pulse signals are introduced into the gear number compensating circuit so as to be converted into two pulse signals having a same frequency. The transmission error is proportional to the phase difference between the two pulse signals having the same frequency, which phase difference is proportional to the ratio of the phase difference time between the two pulse signals to the period of pulse signal. As a consequence, the phase difference time is converted into a clock pulse number by means of the time difference calculation circuit, while at the same time the reciprocal of the period is calculated by means of a reciprocal calculation circuit. The clock pulse number and reciprocal of the period are multiplied in a multiplier so as to obtain the phase difference.

    摘要翻译： 本发明涉及一种齿轮啮合测试仪器，其中在两个齿轮相互啮合的同时测量两个齿轮（驱动齿轮和从动齿轮）之间发生的传动误差。 脉冲发生器分别连接到驱动齿轮和从动齿轮的旋转轴，以便产生具有与齿轮旋转数成正比的频率的两个脉冲信号。 然后，将两个脉冲信号引入齿轮数补偿电路，以便将其转换成具有相同频率的两个脉冲信号。 传输误差与具有相同频率的两个脉冲信号之间的相位差成比例，该相位差与两个脉冲信号之间的相位差时间与脉冲信号周期的比率成比例。 因此，通过时间差计算电路将相位差时间转换成时钟脉冲数，同时通过倒数计算电路计算周期的倒数。 将时钟脉冲数和周期的倒数乘以乘法器以获得相位差。
