Description

мещение нулевых отсчетов исследуемого и эталонного преобразователей и их меток на ленте, а затем включаетс привод. По сигналам формируемым устройствами 5 и 8 в процессе работы преобразователей 2 и 7, на движущуюс ленту нанос тс метки. Рассто ние между двум соседними метками с эталонного и исследуемого преобразователейPlace the zero readings of the test and reference transducers and their marks on the tape, and then the drive turns on. The signals generated by devices 5 and 8 in the process of operation of converters 2 and 7 are marked on the moving tape. The distance between two adjacent labels from the reference and the studied transducers

представл ет собой увеличенную в N V, раз погрешность исследуемого преобразовател в данной точке, где V . Уг - угловые скорости соответственно входного и выходного валов редуктора, R - радиус т гового барабана лентопрот жного механизма. Зна это, путем сопоставлени положений меток с обоих преобразователей, нетрудно рассчитать погрешность исследуемого преобразовател в каждой точке по формуле дг, где дс - рассто ние между с преобразователей в К-ой точке. При этом в результат измерени в кажг дой дискретной точке входит не накопленна погрешность редуктора в данной точке, аis an increase in N V, times the error of the converter under study at a given point, where V. Ang are the angular velocities of the input and output shafts of the gearbox, respectively; R is the radius of the traction drum of the tape mechanism. Knowing this, by comparing the positions of labels from both transducers, it is easy to calculate the error of the transducer under investigation at each point using the formula dg, where dc is the distance between the transducers at the K-th point. In this case, the measurement result at each discrete point includes not the accumulated error of the gearbox at this point, but

лишь изменение величины этой погрешности на угле поворота выходного вала, равном погрешности исследуемого преобразовател в данной точке.only a change in the magnitude of this error at the angle of rotation of the output shaft, equal to the error of the converter under study at a given point.

Claims

In this case, the measurement error will include a variation of the error of the reducer in the area between the reference and real quanta boundaries, which is significantly less than the total error of the reducer. The invention The device for determining the error of the converter according to the author. swith No. 410444, characterized in that, in order to improve the accuracy of the device, the reference converter UGOL-CODE, the driver of the signals at the boundaries of the reference angle quanta and the reference information recording unit are entered, the reference converter of the reference code is installed on the same axis with the test, the reference reference The angle-code converter is connected to the input of the reference information recording unit through a signal shaper at the boundaries of the reference angle quanta.
