Description
(54) УСТРОЙСТВО ДЛЯ ОПРЕДЕЛЕНИЯ СИЛ ТРЕНИЯ(54) DEVICE FOR DETERMINATION OF FORCE OF FRICTION
II
Изобретение относитс к испытани м материалов , в частности к устройствам измерени сил тренн дисперсных материалов.The invention relates to the testing of materials, in particular to devices for measuring the force of dispersed materials.
Известно устройство дл определени сил трени грунта по грунту и грунта по металлу, содержащее корпус, обойму, привод поступательного движени обоймы, систему нагружени и измеритель сил трени .A device is known for determining the strength of ground rubbing and of soil against metal, comprising a housing, a housing, a translational movement of the yoke, a loading system, and a measuring force of friction.
Недостатком указанного устройства вл етс ограниченность длины пути тренн прн однонаправленном относительном перемещении образцов, что не позвол ет проводить длительные испытани материалов н широко измен ть диапазон скоростей.The disadvantage of this device is that the length of the path to the path of the unidirectional relative movement of the samples is limited, which prevents long-term testing of materials and a wide variation in the velocity range.
Известно устройство дл определени сил трени , содержащее основание, обойму, привод вращени обоймы, два нагружающих поршн (ннжннй н верхний), установленных в обойме н образующих с ней камеру дл размещени образца материала, узел иагружени и измеритель момента трени 12).A device for determining friction forces is known, comprising a base, a clip, a clip rotation drive, two loading pistons (above and above), mounted in a cage forming a chamber with it to accommodate a material sample, a friction torque measuring device 12).
Недостатком указанного устройства вл етс невозможность проведени сравнительных испытаний на трение одного образца грунта по грунту н по металлу, вследствие того, что в обойму можно установить лишьThe disadvantage of this device is the impossibility of conducting comparative tests on the friction of a single soil sample on the ground and on metal, due to the fact that only
один образец (грунта или металла), а дл проведени второго испытани необходимо замен ть образцы, наруша при этом образец грунта, установленный в камере.one sample (soil or metal), and for the second test it is necessary to replace the sample, thus violating the soil sample installed in the chamber.
Целью нзобретеин вл етс расширение технологических возможностей устройства.The purpose of the invention is to expand the technological capabilities of the device.
Поставленна цель достнгаетс тем, что внутренн поверхность обоймы выполнена ступенчатой, а нижний поршень установлен с возможностью перемещени вдоль оси обоймы.The goal is achieved by the fact that the inner surface of the yoke is stepped, and the lower piston is mounted for movement along the yoke axis.
На фиг. I изображено устройство при исследовании трени грунта по грунту, продольный разрез; на фиг. 2 - то же, при исследовании тренн грунта по металлу.FIG. I shows the device in the study of soil friction on the ground, a longitudinal section; in fig. 2 - the same, in the study of the soil trend on the metal.
