Известны спидометры с магнитом на приводном валике, картушкой на одной оси со стрелкой и спиральной пружиной противодействующего момента. Валик магнита находитс в фрикционной паре с осью картушки, что вызывает ускоренный износ трущихс частей, засорение прибора и, как следствие, снижение точности измерений.Known speedometers with a magnet on the drive roller, a card on the same axis with an arrow and a coil spring of the opposing moment. The magnet roller is in friction pair with the axis of the card, which causes accelerated wear of the friction parts, clogging of the device and, as a result, a decrease in the measurement accuracy.
Предложенный спидометр отличаетс тем, что между магнитом и картушкой укреплен разделительный элемент в виде колпачка, внутренн часть которого служит подшипниковой опорой оси картушки. Это повышает надежность прибора и точность измерений.The proposed speedometer is characterized in that a separating element in the form of a cap is fixed between the magnet and the card and the inner part of which serves as a bearing support for the axis of the card. This improves instrument reliability and measurement accuracy.
На чертеже схематично представлен спидометр .The drawing shows a schematic speedometer.
На нриводном валике 1 укреплен цилиндрический посто нный магнит 2. На ось 3 жестко посажена стаканообразна картушка 4. Между картущкой и магнитом укреплеи разделительный элемент 5 в виде колпака из немагнитного материала, например пластмассы, образующий подшипниковую опору дл оси 3. Картушка снабжена экраном 6 из магнитном гкого материала. Противодействующий момент создаетс спиральной пружиной 7. Один ее конец жестко св зан с корпусом, а второй - с осью 3, на которой укреплена стрелка 8, перемещающа с над шкалой 9, проградуированной в единицах скорости пли оборотов.A cylindrical permanent magnet 2 is fastened on the roller roller 1. A glass-like card 4 is rigidly seated on the axis 3. A separating element 5 in the form of a cap made of a nonmagnetic material, such as plastic, forming a bearing support for the axis 3, is fixed between the card-piece and the magnet. magnetic harsh material. The opposing moment is created by the coil spring 7. One of its ends is rigidly connected to the body, and the second to the axis 3, on which the arrow 8 is fixed, moving over the scale 9, calibrated in units of speed or turns.
Валик 1 приводитс во от контролируемого объекта. Силовые линии вращающегос магнита 2, проника через колпак 5, замыкаютс через экран 6 и, пересека картущку 4, возбуждают в ней ЭДС, пропорциональную скорости вращени магнита. Возникающие в картущке электрические токиRoller 1 is driven from the monitored object. The lines of force of the rotating magnet 2, penetrating through the cap 5, are closed through the screen 6 and, crossing the card reader 4, excite an emf in it proportional to the speed of the magnet. Electric currents arising in the card reader
создают магнитное поле. Взаимодейству с полем магнита 2, оно поворачивает картушку в сторону вращени магнита на угол, величина которого пропорциональна контролируемой скорости, например, автомобил . Моментcreate a magnetic field. Interacting with the field of the magnet 2, it rotates the card in the direction of rotation of the magnet by an angle whose magnitude is proportional to the controlled speed, for example, a car. Moment
взаимодействи магнитных нолей уравновешиваетс пружиной 7.the interaction of magnetic fields is balanced by the spring 7.
Предмет изобретени Subject invention
Спидометр, содержащий магнит, укрепленный на приводном валике, картушку, закренленную на одной оси со стрелкой, и спиральную пружину противодействующего момента, о т л и ч а ю щ и и с тем, что, с целью повыщенп надежностп и точности измерений, между магнитом и картущкой укреплен разделительный элемент в виде колпака, внутренн часть которого служит иодшииниковой опорой оси картушки.A speedometer containing a magnet mounted on a drive roller, a card zaklennye on the same axis with the arrow, and a coil spring of the opposing momentum, which is so that, in order to increase reliability and measurement accuracy, between the magnet and with a card, a separating element in the form of a cap is strengthened, the inner part of which serves as the iodine support of the axis of the card.
