Изобретение относитс к испытательной технике.This invention relates to a testing technique.

Известно устройство дл исследовани прочности таблеток на истирание, содержащее основание, установленный на нем с возможностью вращени барабан, внутренн поверхность которого выполнена с микрорельефом, и привод вращени барабана l.A device for examining the resistance of tablets to abrasion is known, comprising a base, a rotatable drum mounted on it, the inner surface of which is made with a microrelief, and a rotation drive of the drum l.

Известное устройство не обеспечивает качественной оценки механической прочности таблеток на истираниеи затрудн ет очистку устройства от образовавшейс пыли.The known device does not provide a qualitative assessment of the mechanical strength of the abrasion tablets and makes it difficult to clean the device from the resulting dust.

Цель изобретени - повышение достоверности исследовани .The purpose of the invention is to increase the reliability of the study.

Указанна цель достигаетс тем, что устрюйство снабжено пыпесборником, размещенным внутри барабана, а его микрорельеф выполнен в виде канавок синусоидной формы, нанесенных по винтовой линии.This goal is achieved by the fact that the device is equipped with a dust collector placed inside the drum, and its microrelief is made in the form of sinusoidal grooves applied along a helix.

На чертеже представлено предлагаемое устройство.The drawing shows the proposed device.

Устройство содержит основание 1, барабан 2, установленный на валу 3, пылесборник 4, также размещенный на валу 3, на внутренней поверхности барабана выполнены канавки 5 синусоидной формы. Барабан снабжен люком 6 дл загрузки таблеток.The device comprises a base 1, a drum 2 mounted on the shaft 3, a dust collector 4, also placed on the shaft 3, on the inner surface of the drum grooves 5 are sinusoidal in shape. The drum is provided with a hatch 6 for loading tablets.

Устройство работает следующим об,- разом.The device works as follows, at a time.

Claims

The tablets to be examined are loaded through the hatch 6 into the drum 2, which is driven into rotation (the drive is not shown). A segmental dust collector 4 is installed on the drum axis, which makes it easy to clean the device from dust generated during the abrasion of the tablets, and also prevents the forcible circular rotation of the tablets under the action of centrifugal force, if this factor occurs during the experiment. For a more complete assessment of the mechanical strength of the studied tablets for abrasion, the working surface of the drum is provided with a microrelief in the form of one or several intersecting grooves having the shape of a sinusoid superimposed on the helix, and to increase the sliding area of the tablets along the working surface of the drum the central angle of the segmental dust collector does not exceed 90. The invention The device for examining the strength of abrasion tablets, containing the base mounted on it with the air 6843 5 10 15

W 64 the possibility of rotation of the drum, the inner surface of which is made with microrelief, and the drive of the rotation of the drum, characterized in that, in order to increase the reliability of these studies, it is equipped with a bag collector, re-positioned. inside the drum, and its microrelfer is made in the form of sinusoidal grooves applied along a helix.
