(5) ПРИБОР ДЛЯ ОПРЕДЕЛЕНИЯ КОЭФФИЦИЕНТА ТРЕНИЯ СКОЛЬЖЕНИЯ МЕТОДОМ ЗАТУХАЮЩИХ КОЛЕБАНИЙ(5) DEVICE FOR DETERMINATION OF THE SLIP COEFFICIENT OF THE SLIDING BY THE METHOD OF SWOATING VIBRATIONS
II
Изобретение относитс к устройствам дл исследовани фрикционных характеристик подшипниковых материалов методом затухающих колебаний.The invention relates to devices for studying the frictional characteristics of bearing materials by the damped oscillation method.
По основному авт.св. №291137 известен прибор дл определени коэффициента трени скольжени методом затухающих колебаний, содержащий станину, ма тник, выполненный в виде консольной балки из материала с низкими потер ми на внутреннее трение, котора несет на свободном конце груз с закрепленными по бокам подвижными плоскими образцами, и взаимодействующие с ними неподвижные образцы , установленные на станине с помощью плоских консольных балок-пружин с регулируемым нат гом. Кроме того, прибор имеет устройство дл приведени ма тника в колебательное движение , которое выполнено в виде электромагнита , включенного на выход звукового генератора, тензометра и регистрирующего блока LlJНедостатком известного прибора вл етс низка точность резул1 татов испытаний, что обусловлено необходимостью применени съемных консольных балок, тщательности их заделки и тарировки при каждом испытании, так как частоты собственных колебаний балок должны входить в требуемый диапазон частот.According to the main auth. No. 291137 is a known device for determining the friction coefficient of a slip by the damped oscillation method, which contains a frame, an original made in the form of a cantilever beam made of a material with low internal friction losses, which carries a load with fixed moving specimens at its free end and with them are fixed specimens mounted on the frame with the help of flat cantilever spring beams with adjustable tension. In addition, the device has a device for vibrating movement of the manna, which is made in the form of an electromagnet, connected to the output of the sound generator, strain gauge and recording unit LlJ. their termination and calibration during each test, since the natural frequencies of the beams must be within the required frequency range.
Цель изобретени - повышение точности измерений коэффициента трени скольжени .The purpose of the invention is to improve the accuracy of measurement of the coefficient of friction slip.
Поставленна цель достигаетс тем,, что прибор снабжен грузом с перемейной массой, а груз, балкипружины и электромагнит установлены с возможностью фиксированного перемещени вдоль балки.The goal is achieved by the fact that the device is supplied with a load with a subsurface weight, and the load, spring beams and electromagnet are installed with the possibility of fixed movement along the beam.
На чертеже изображен предлагаемый прибор.The drawing shows the proposed device.
Прибор содержит станину 1, консольную балку 2, груз 3 с переменной массой, каретку Ц, плоские балки-пружины 5, электромагнит 6, звуThe device contains a frame 1, a cantilever beam 2, a load 3 with variable mass, carriage C, flat beams-springs 5, an electromagnet 6, sound
