Description
Известные устройства дл измерени разности скоростей вращени двух валов, вращающихс в противоположные стороны, не позвол ют осуществл ть непосредственный отсчет.The prior art devices for measuring the difference in the speeds of rotation of two shafts rotating in opposite directions do not allow a direct reading.
В предлагаемом устройстве указанный недостаток устранен.In the proposed device, this disadvantage is eliminated.
Это достигаетс в результате того, что на валы насажены металлические диски, расноложенные в поле поворотного посто нного магнита, удерживаемого пружиной и несущего указатель.This is achieved as a result of the metal disks mounted on the shafts, which are located in the field of a rotatable constant magnet held by a spring and carrying a pointer.
На чертеже изображена принципиальна схема предлагаемого устройства.The drawing shows a schematic diagram of the proposed device.
Устройство состоит из двух дисков / и 2, вращающихс в противоположные стороны в поле посто нного магнита 3. Один диск приводитс во вращение от вала 4 синхронного двигател , питающегос от той же сети переменного тока, что и испытываемый двигатель. Другой диск сидит на валу 5, жестко св занном с валом ротора испытываемого двигател .The device consists of two disks / and 2, rotating in opposite directions in the field of the permanent magnet 3. One disk is driven in rotation from the shaft 4 of a synchronous motor, powered by the same AC mains as the motor under test. The other disk sits on the shaft 5, which is rigidly connected to the rotor shaft of the engine under test.
Посто нный магнит 5 расположен на валу б, к которому прикреплена стрелка 7. Повороту магнитов преп тствует спиральна пружина 8.The permanent magnet 5 is located on the shaft b, to which the arrow 7 is attached. The helical spring 8 prevents the rotation of the magnets.
При равенстве скоростей вращени обоих дисков результирующий момент, действующий на магнит, равен нулю, а при их неравенстве угол поворота магнита 5, а следовательно, и стрелки 7 пропорционален измер емой разности скоростей вращени . Шкала 9 позвол ет производить непосредственный отсчет разности скоростей вращени валов 4 и 5.With equal speeds of rotation of both disks, the resulting moment acting on the magnet is zero, and if they are unequal, the angle of rotation of the magnet 5, and hence the arrow 7, is proportional to the measured difference in the speeds of rotation. The scale 9 allows direct reading of the difference in the speeds of rotation of the shafts 4 and 5.
Устройство дл измерени разности скоростей вращени двух валов, вращающихс в противоположные стороны, отличающеес тем, что, с целью получени непосредственного отсчета, на указанные валь насажены металлические диски, расположенные в поле поворотного по сто нного магнита, удерживаемого пружиной и несущего указатель.An apparatus for measuring the difference in the speeds of rotation of two shafts rotating in opposite directions, characterized in that, in order to obtain a direct reference, metal discs mounted on said shaft are located in the field of a rotatable standing magnet held by a spring and carrying a pointer.
