Description

(54) МАГНИТОУПРУГИЙ ДАТЧИК КРУТЯЩЕГО МОМЕНТА(54) MAGNETIC ELASTIC TORQUE SENSOR

Изобретение относитс  к области силоизмерительной техники и может быть использовано дл  измерени  крут щих мо.ментов в металлорежущих станках, оснащаемых системами автоматического управлени  процессом резани . Известный магнитоупругий датчик крут щего момента, содержащий три неподвижных кольцевых электромагнита с  вно выраженными полюсами, расположенных концентрично с контролируемым участком вала, средний из которых несет на полюсах обмотки возбуждени , а крайние -измерительные обмотки, не обеспечивает требуемой точности измерений I. Наиболее близким по технической сущности к изобретению  вл етс  магнитоупругий датчик крут щего момента, содержащий упругий вал и электромагнитную систему , включающую две тороидальные катушки , расположенные вокруг вала, на каждой из которых размещено по одной обмотке возбуждени  и измерительной обмотке 2. Недостатками такого датчика  вл ютс  низка  чувствительность и нечувствительность к знаку крут щего момента. Целью изобретени   вл етс  повышение чувствительности при измерении знакопеременных моментов. Это достигаетс  за счет того, что в предлагаемом датчике на поверхности вала под катушками выполнены две группы прорезей , направленных встречно друг другу и под углом 45° к оси вала, а также за счет того, что катушки размещены на каркасал, выполненных из антифрикционного диэлектрика и опирающихс  непосредственно на вал. Описываемый датчик представлен на чертеже . Магнитоупругий датчик крут щего момента содержит две катущки, каркасы которых I и 2 изготовлены из антифрикционного диэлектрика и служат одновре.менно подщипниками скольжени , с помощью которых он устанавливаетс  на валу 3. На каждом каркасе 1 и 2 намотано по две обмотки . Обмотки 4 и 5  вл ютс  намагничивающими , а обмотки 6 и 7 - измерительными . Катушки заключены внутри магнитопроводов , состо щих из дисков 8 и колец 9. Все магнитопроводы набраны из лисThe invention relates to the field of force-measuring equipment and can be used to measure torque tools in machine tools equipped with automatic control systems for the cutting process. The known magnetoelastic torque sensor containing three stationary ring electromagnets with pronounced poles concentric with a controlled shaft section, the middle of which carries an excitation winding at the poles, and the extreme measuring windings do not provide the required measurement accuracy I. The closest to the technical The essence of the invention is a magnetoelastic torque sensor, comprising an elastic shaft and an electromagnetic system including two toroidal coils, located Around the shaft, each of which contains one excitation winding and measuring winding 2. The disadvantages of such a sensor are low sensitivity and insensitivity to the sign of the torque. The aim of the invention is to increase the sensitivity when measuring alternating moments. This is achieved due to the fact that in the proposed sensor on the shaft surface under the coils there are two groups of slots directed opposite to each other and at an angle of 45 ° to the shaft axis, and also due to the fact that the coils are placed on a frame made of an antifriction dielectric and directly supported on the shaft. The described sensor is represented in the drawing. The magnetoelastic torque sensor contains two rolls, the frames of which I and 2 are made of an antifriction dielectric and simultaneously serve as sliding bearings with which they are mounted on the shaft 3. Two windings are wound on each frame 1 and 2. Winding 4 and 5 are magnetizing, and winding 6 and 7 are measuring. The coils are enclosed inside magnetic cores consisting of disks 8 and rings 9. All magnetic cores are made of foxes.
