Description
В технике испытани материалов на твёрдость, примен ютс ма тники , затухающие колебани которых служат критерием дл определени твёрдости материалов. Ма тники при этом опираютс на испытуемое тело.In the technique of testing materials for hardness, weights are applied, damped oscillations of which serve as a criterion for determining the hardness of materials. In this case, the pivots rest on the test body.
В предлагаемом ycTpoiicTBe дл определени твёрдости также использован 1ма тник, но отличаетс это устройство тем, что в нём применена подставка дл ма тника, снабжённа канавками, в которых располагаютс испытуемые образцы .In the proposed ycTpoiicTBe, a tint is also used to determine hardness, but this device is different in that it uses a tambour stand equipped with grooves in which the test specimens are located.
На чертеже изображено предлагаемое устройство.The drawing shows the proposed device.
На стойке 4 установлена подставка 3 с двум параллельныМи полукруглыми канавками. Подставка располагаетс канавками вверх. В канавки вкладываютс испытуемые образцы 5 (кругла проволока)A support 3 with two parallel semicircular grooves is installed on the rack 4. The stand is grooved upwards. Test samples 5 (round wire) are inserted into the grooves.
и на нух опускаетс фермочка 1 с консольно подвешенным к ней ма тником 2. Основани Г фермочки, которыми Она опираетс на образцы 5, закруглены снизу.and the farmhouse 1 is lowered with a cane suspended from a console 2. The bases of the farm, with which she leans on samples 5, are rounded from the bottom.
Ма тник заставл ют качатьс в ПЛОСКОСТИ чертел а и по времени затухани его колебаний суд т о твёрдости тел.The master is forced to swing in the PLANE of the outline and, according to the damping time of its oscillations, judge the hardness of the bodies.

YcTpoiiCTBO ДЛЯ определени твёрдости тел, основаннсе на затухании колебаний ма тника, опирающегос на испытуемое тело, о т .:i пчающеес тем, что дл возможности испытани тел, имеющих цилиндрическую ИЛИ круглую форму, применена подставка дл ма тника, снабжённа канавками, предназначенными ДЛЯ расположени в них испытуемых образцов.YcTpoiiCTBO FOR DETERMINING THE HARDNESS OF THE BODY, based on the attenuation of the oscillations of a tandem resting on the body under test, I was told that in order to test bodies having a cylindrical OR circular shape, a trestle holder was used, equipped with grooves intended FOR test specimens in them.
