Изобретение относитс к .области приборостроени и может быть испольi зовано как устройство дл измерени линейного смещени вала в целом р де измерительной и эксплуатационной аппаратуре автономно или в комплексе с другими блоками.The invention relates to the field of instrumentation and can be used as a device for measuring the linear displacement of a shaft in a whole series of measuring and operating equipment autonomously or in combination with other blocks.
Известно устройство дл измерени линейного смещени валов, что осуществл ет индикацию скорости этого перемещени , так и иной скорости 1 Такое устройство содержит несколько фотопреобразователей и источников света, что делает его энергетически емким и недостаточно надежным в работе . Кроме того, дл настройки такого устройства требуютс высококвалифицированные операторы, что еще более удорожает устройство.A device is known for measuring the linear displacement of shafts, which provides an indication of the speed of this movement, as well as a different speed. 1 Such a device contains several photo-transducers and light sources, which makes it energetically capacious and not reliable enough in operation. In addition, highly skilled operators are required to configure such a device, which further increases the cost of the device.
Известно также устройство дл измерени линейного смещени вала, содержащее собственно вал, его опоры, фотопрёобразователь, подключенный через усилитб-ль к индикатору,,и ctyпицу 2. Но точность проводимых измерений в этом случае, а тем более в выбранном интервале времени, оказываетс недостаточно высокой.It is also known a device for measuring the linear displacement of a shaft, which contains the shaft itself, its supports, a phototransducer connected via an amplifier to the indicator, and ctypits 2. But the accuracy of the measurements in this case, and even more so in the selected time interval, is not high .
Целью изобретени вл етс повышение точности измерений в выбранном интервале времени.The aim of the invention is to improve the accuracy of measurements in a selected time interval.
Поставленна цель достигаетс за счет того, что концы вала снабжены .сферическими элементами, один из которых установлен вчашеобразной опоре , ..а другой - в плоской, ступица выполнена в виде жестко скрепленного The goal is achieved due to the fact that the ends of the shaft are provided with spherical elements, one of which is installed in the base of the support, the other in a flat, the hub is made in the form of rigidly fastened
0 с валом диска, поверхность которого снабжена светоотражающим элементом, а в само устройство введен пьезопреобразовате/ ,ъ, установленный в чашеобразной опоре под сферическим эле5 ментом.0 with a disk shaft, the surface of which is provided with a light-reflecting element, and a piezotransform /, ъ is inserted into the device, mounted in a cup-shaped support under the spherical element.
На чертеже показана конструкци описываемого устройства.The drawing shows the structure of the described device.
На валу 1 жестко закреплен диск 2, а сам вал установлен в плоской опоре The disk 2 is rigidly fixed on the shaft 1, and the shaft itself is mounted in a flat support
0 3 и в чашеобразной опоре 4, в полости которой расположены износоустойчивый подп тник 5 и пьезопреобразователь (ПП) 6. На поверхности диска имеетс светоотражающий элемент 7, 0 3 and in the cup-shaped support 4, in the cavity of which there is a wear-resistant subframe 5 and piezotransducer (PP) 6. On the surface of the disk there is a reflective element 7,
5 выполненный, например, из полированной металлической ленты. Фотопреобразователь В, воспринимающий лучи, отраженные от поверхности элемент.а 7, через усилитель 9 подключен к ин05 made, for example, from polished metal tape. Photoconverter B, receiving the rays reflected from the surface element. And 7, through the amplifier 9 is connected to in0
