Description

Известны установки дл  контрол  за работой коленчатых валов двигателей , в которых обычно проволочный тензометр наклеиваетс  на испытуемый вал и включаетс  в цепь регистрирующего устройства.Installations are known for monitoring the operation of crankshafts of engines, in which a wire strain gauge is usually glued to the test shaft and connected to a recording device circuit.

Предлагаемое устройство предназначено дл  наблюдени  и контрол , а также изучени  деформаций (за исключением крутильных) и напр жений коленчатых валов двигателей во врем  их работы. Измерение колебаний коленчатого вала производитс  с помощью тензометра, включенного в электрическую цепь регистрирующего устройства. Запись диаграммы колебаний фиксируетс  на светочувствительной ленте.The proposed device is intended to monitor and control, as well as the study of deformations (except for torsional) and stresses of the engine crankshafts during their operation. The crankshaft oscillations are measured using a strain gauge included in the electrical circuit of the recording device. The recording of the vibration pattern is fixed on the photosensitive tape.

Описываемое устройство дает возможность выделить из сложных деформаций вала деформации, св занные только с биением вала, характеризующим состо ние зазора между подщипником и валом.The described device makes it possible to isolate from complex deformations of the shaft, deformations associated only with shaft beating, which characterize the state of the gap between the bearing and the shaft.

Это достигаетс  с помощью подпружиненного штыр , установленного в крышке подшипника. Штырь одним концом прижат к шейке вала, а другим к упругой мембране. Все колебани  вала передаютс  через штырь на упругий элемент-мембрану, на которой наклеен проволочный тензометр, включенный в цепь электрического регистрируюшего устройства .This is achieved by means of a spring-loaded pin installed in the bearing cap. The pin is at one end pressed to the shaft neck, and the other to the elastic membrane. All vibrations of the shaft are transmitted through a pin to an elastic element-membrane, on which a wire strain gauge is connected, which is connected to an electrical recording device circuit.

Такое устройство дает возможность проводить повседневный контроль за состо нием подшипников и износом коренных шеек коленчаты.х валов.Such a device makes it possible to carry out day-to-day monitoring of the condition of bearings and the wear of the main journals of the crankshafts.

На чертеже приведена схема устройства.The drawing shows a diagram of the device.

В крышке подшипника / установлен штырь 2, контактирующий с коренной шейкой коленчатого вала 3. Штырь 2 одним концом прижимаетс  к шейке вала с помощью пружинки 4, а другим опираетс  на упругий элемент 5 типа мембраны. На мембрану наклеен проволочный тензометр , включенный в электрическую цепь.The bearing cap / pin 2 is in contact with the main journal of the crankshaft 3. The pin 2 is pressed at one end against the shaft journal by means of the spring 4, and the other rests on the elastic element 5 of the diaphragm type. On the membrane is glued wire strain gauge, included in the electrical circuit.

Возникающие в электрической цепи изменени  силы тока воздействуют на регистрирующее устройство (на чертеже не показано), где производитс  запись диаграммы колебаний на светочувствительной ленте.The changes in the current intensity occurring in the electric circuit affect the recording device (not shown in the drawing), where the recording of the oscillation pattern on the photosensitive tape is performed.

№ 86863- 2 Предмет изобретени No. 86863- 2 The subject invention

- Устройство дл  контрол  за работой коленчатых валов двигателей с применением проволочных тензометров и регистрирующего устройства с записью диаграммы колебаний на светочувствительной ленте, о т л и ч а ющ ее с,  тем, что, с целью регистрации биений коленчатого вала двигател , вызванных наличием зазоров, и обеспечени  контрол  за состо нием подшипников и коренных шеек вала, оно выполнено в виде контактирующего с валом подпружиненного штыр , установленного в крышке подшипника и опирающегос  другим кониом на упругий элемент типа мембраны, на котором наклеен проволочный тензометр, включенный в электрическую цепь регистрирующего устройства.- a device for monitoring the operation of engine crankshafts using wire strain gauges and a recording device with recording an oscillation pattern on a photosensitive tape, which is based on the fact that, in order to register the beat of the crankshaft of an engine caused by the presence of gaps, and monitoring the condition of the bearings and the main journals of the shaft, it is made in the form of a spring-loaded pin in contact with the shaft, installed in the bearing cap and supported by another horse on an elastic element such as a membrane s on which wire strain gauge is pasted included in the electric circuit of the recording apparatus.
