Description
Изобретение относитс к области метрологии , а именно к снособам измерени крут щих моментов, и может быть иснользовано при измерении малых величин моментов, создаваемых датчиками измерени угла, момента и т. п. элементов.The invention relates to the field of metrology, namely to methods for measuring torque, and can be used in measuring small values of moments produced by sensors measuring angle, moment, and so on.
Известен способ измерени крут щих моментов по углу закручивани упругой нити.A method is known for measuring torques by the angle of twist of an elastic thread.
Недостатком известного способа вл етс низка точность измерени малых моментов, так :Как нередко мо.менты собственного трени превышают их величины.The disadvantage of this method is the low accuracy of measurement of small moments, as: As often the movement of its own friction exceeds their size.
В предлагаемом способе этот недостаток устранен тем, что к упругой нити прикладывают дополнительный внешний момент, направленный в сторону действи измер емого момента.In the proposed method, this disadvantage is eliminated by the fact that an additional external moment is applied to the elastic thread in the direction of the action of the measured moment.
На чертеже показано устройство, реализуюш:ее предлагаемый способ.The drawing shows the device, implement: its proposed method.
Дл измерени крут ш,его момента, возникающего между статором / и ротором 2 провер емого прибора, ротор закрепл ют в узле 3 креплени , жестко соединенном с упругойIn order to measure the toughness of w, its moment arising between the stator / and the rotor 2 of the device under test, the rotor is fixed in the attachment unit 3 rigidly connected to the elastic
нитью 4. С помощью, например, электромагнитов 5 и 6 к упругой нити прикладывают дополнительный внешний момент, направленный в сторону действи измер емого момента .между статором и ротором провер емого прибора. Поскольку су.ммарный момент возрастает по величине, то его измерение пронзводнтс с повышенной точностью, ввиду большего угла закручивани упругой нити.Thread 4. With the help of, for example, electromagnets 5 and 6, an additional external moment is applied to the elastic thread, directed in the direction of the measured moment, between the stator and the rotor of the device under test. Since the total instant increases in magnitude, its measurement penetrates with increased accuracy due to the larger twist angle of the elastic thread.
Учитыва тщательно оттарированную величину дополнительного внешнего момента, определ ют искомый момент между статором и ротором провер емого прибора.Taking into account the carefully otted value of the additional external moment, determine the required moment between the stator and the rotor of the device under test.
Предмет изобретени Subject invention
Способ измерени крут щих моментов по углу закручивани упругой нити, отличаюи{пйс тем, что, с целью повышени точности измерени малых моментов, к унругой нити прикладывают дополнительный внешний момент , направленный в сторону действи измер емого момента.The method of measuring torsional moments by the angle of twist of the elastic yarn is distinguished {by the fact that, in order to improve the accuracy of measuring small moments, an additional external moment is applied to the external yarn in the direction of the measured torque.
