(54) СПОСОБ КОНТРОЛЯ ШАГА СВИВКИ СОСТАВЛЯЮЩИХ(54) METHOD OF CONTROLING THE PITCH OF A PIGETTING COMPONENTS
ЭЛЕМЕНТОВ ВИТЫХ ОБЪЕКТОВ, НАПРИМЕР КАНАТОВ ELEMENTS OF TWISTED OBJECTS, FOR EXAMPLE ROPES
Изобретение относитс ft областитехнических измерений, а именно к контролю параметров витых объектов, например канатов или тросов.The invention relates to the field of technical measurements, namely to the control parameters of twisted objects, such as ropes or cables.
Известны способы контрол шага свивки составл ющих элементов витых. объектов, например канатов или тросов, заключающиес в определении liiatia свивки по полученному отпечатку или непосредственным измерением 1Known methods for controlling the stride pitch of the constituent elements are twisted. objects, such as ropes or cables, that determine liiatia lay according to the imprint or direct measurement 1
Однако известные способы не позвол ют определить величину упругой отдачи шага свивки, возникающей в витых издели х, облгц ающих свойствами упругой и остаточной деформаций.However, the known methods do not allow to determine the magnitude of the elastic recoil of the stride pitch arising in twisted products, which are characterized by the properties of elastic and residual deformations.
Цель изобретени - измерение величины упругой отдачи шага свивки в отрезанном от объекта образце.The purpose of the invention is to measure the magnitude of the elastic recoil of the stride pitch in a sample cut from the object.
Поставленна цель достигаетс тем, что, на контролируемом объекте отмечгиот метками образец расчетной величины , устанавливают зажимы на концах отмеченного образца, вырезают образец по нанесённым меткам, снимают зажимы, замер ют фактическую длину отрезанного образца и по разности между отмеченной и измеренной длинами определ ют величину упругой от дачи шага свивки в отрезанном образце . ИЛИ ТРОСОВThe goal is achieved by the fact that on a controlled object marks a sample of a calculated value, install clips on the ends of the marked sample, cut out the sample from the marked marks, remove the clips, measure the actual length of the cut sample, and determine the elastic value from the difference between the marked and measured lengths from giving stride step in the cut off sample. OR CABLES
Способ осуществл етс следуквдим образом.The method is carried out in the following manner.
В готовом изделии замер ют шаг свивКи составл ющих элементов путем его непосредственного измерени или по полученному отпечатку. Далее на готовом изделии отмечают с требуемой точностью образец расчетной величины обычными универсальными средства10 ми и крайние точки отмеренного образца фиксируют метками, нанесенными любым способом, гарантирующим необходимую точность. На концах отмеченного образца устанавливают зажимы. In the finished product, the step of twisting the constituent elements is measured by its direct measurement or by the received print. Then, on the finished product, the sample of the calculated value is marked with the required accuracy using standard universal means and the extreme points of the measured sample are fixed with marks applied in any way that guarantees the required accuracy. At the ends of the marked sample set clips.
15 Вырезают образец по нанесенные меткам , выдержива при этом перпендикул рность торцовых плоскостей, к продольной оси образца. После отрезки аккуратно снимают зашимы и замер ют 15 Cut the specimen using the markings, while maintaining the perpendicularity of the end planes, to the longitudinal axis of the specimen. After the segments, carefully remove the stitches and measure them.
20 длину отрезка с той же точностью, что и при нанесении меток. Разность между отмеченной и измеренной длинами (в пересчете на размер шага) характеризует величину упругой отда25 чи шага свивки в отрезанном образце .20 length of the segment with the same accuracy as when applying labels. The difference between the marked and measured lengths (in terms of step size) characterizes the magnitude of the elastic recoil of the stripe step in the cut sample.
Эффективность предлагаемого способа про вл етс при учете возникаю30 щих осевых усилий при резке канатов. .The effectiveness of the proposed method is manifested when taking into account the arising axial forces when cutting ropes. .
