Description
щего с шипом 14) установленным на втулке 11, силовую пружину 15, эксцентриковый силовозбуди1 ель 16, шарниры Гука 17 и рычаг 18, одним концом шарнирно .св занный с рычагом 9 второго рода, а другим - жестко с силовозбудителем 16.with a spike 14) mounted on the sleeve 11, the power spring 15, eccentric silo 16, Hook 17 hinges and the lever 18, hinged at one end connected with the lever 9 of the second kind, and the other rigidly with the exciter 16.
Устройство работает следующим образом.The device works as follows.
Образец 2 устанавливают в держателе 1, контробразец 8 закрепл ют в держателе 7, с помош,ью пружины 15 создают статическую нагрузку на исследуемую пару трени , с помощью силовозбудител 16 - динамическую, ползун 10 перемещают на фиксированное рассто ние или по заданной зависимости вдоль рычага 9 с помощью кулачкового механизма 13, и включают привод держател 1 образца 2,Sample 2 is installed in the holder 1, the contra-sample 8 is fixed in the holder 7, with the help of springs 15 they create a static load on the test pair of friction, with the help of a power driver 16 - dynamic, the slider 10 is moved for a fixed distance or along a predetermined dependence along the lever 9 using the cam mechanism 13, and turn on the drive of the holder 1 of sample 2,
Поскольку данное устройство снабжено дополнительным рычагом 18, установленным между рычагом 9 второго рода и силовозбудителем 16 и подвижной опорой, то оно позвол ет имитировать режим нагружени испытуемой пары трени , измен ющийс от цикла к циклу, а также нестационарный внутри любого цикла. Необходима зависимость изменени нагрузки от цикла к циклу достигаетс путем подбора масс эксцентрикового силовозбудител , их взаимного расположени и частот вращени . Изменение нагрузки внутри любого цикла обеспечиваетс перемещением подвижной опоры во врем испытани . Применение предложенного устройства позволит приблизить услови испытаний к эксплуатационным и тем самым повысить надежность и достоверность результатов эксперимента по определению износа пар трени при нестационарном режиме нагружени .Since this device is equipped with an additional lever 18 installed between the lever of the second type 9 and the force actuator 16 and the movable support, it allows to simulate the loading mode of the test pair of friction, varying from cycle to cycle, as well as non-stationary within any cycle. The necessary dependence of the load on the cycle to the cycle is achieved by selecting the masses of the eccentric force driver, their relative position and rotational frequencies. The change in load within any cycle is provided by moving the movable support during the test. The use of the proposed device will make it possible to bring the test conditions closer to the operational ones and thereby increase the reliability and reliability of the results of the experiment to determine the wear of friction pairs under non-stationary loading.
