Description

Изобретение относитс  к сельско- хоз йственному машиностроению, пре- . имущественно к сегментам режущих аппаратов сельскохоз йственных машин,FIELD: agricultural engineering; property to the segments of agricultural machines cutting machines,

Известен сегмент режуи(6го аппарата сельскохоз йственных машин, на режущей кромке которого выполнена насечка, образованна  зубь ми и межзубьевыми впадинс1ми Ij.A famous segment of the rezhuy (the 6th apparatus of agricultural machines, on the cutting edge of which a notch is made, formed by the teeth and interdental cavities Ij.

Известный сегмент имеет недостаток , состо щий в том, что зубь  его насечки обладают низкой прочностью , так как углы заточки зубьев и межзубьевых впадин одинаковы, а зуб при этом несет более высокую удельную нагрузку и поэтому менее прочен и надежен в работе в сравнении с участками режущей грани сегмента, расположенными во впадинах.The known segment has the disadvantage that the teeth of its notches have low strength, since the angles of sharpening of the teeth and interdental depressions are the same, while the tooth carries a higher specific load and therefore is less durable and reliable in operation compared to the cutting areas the edges of the segment located in the depressions.

Целью изобретени   вл етс  повышение прочности сегмента и надежности его работы.The aim of the invention is to increase the strength of the segment and the reliability of its operation.

Поставленна  цель достигаетс  тем, что угол заточки сегмента на вершинах зубьев больше угла заточки в межзубьевых впадинах.The goal is achieved by the fact that the sharpening angle of the segment on the tops of the teeth is greater than the sharpening angle in the interdental cavities.

На фиг. 1 изображен сегмент режу него аппарата; на фиг. 2 - разрез Л-Л на фиг. 1; на фиг. 3 - узел I на фиг. (,форма режуией грани ,FIG. 1 shows a segment of the apparatus being cut; in fig. 2 is a section LL in FIG. one; in fig. 3 shows the node I in FIG. (, the form of the cutting edge,

Сегмент 1 снабжен насечкой 2 и содержит режущие кромки 3, зубь  4 насечки и межзубьевые впадины 5. с Угол заточки вершины зубьев d больше угла заточки межзубьевых впадин /5 .Segment 1 is provided with notch 2 and contains cutting edges 3, teeth 4 notches and interdental depressions 5. with the angle of grinding of the tips of the teeth d is greater than the angle of grinding of the interdental cavities / 5.

Работа сегмента не отличаетс  от .работы известных сегментов. 10 Приведенное соотношение величины угла заточки зуба и угла заточки впадины приводит к тому, что повышаетс  прочность режущей . грани сегмента и надежность его работы .The operation of a segment does not differ from the work of known segments. 10 The above ratio of the magnitude of the sharpening angle of the tooth and the angle of sharpening of the trough leads to an increase in the cutting strength. the brink segment and the reliability of his work.

1515

Сегменты с таким соотношением углов заточки более долговечны и надежны в работе по сравнению с сегментами , где угол заточки вершины зуба Segments with such a ratio of sharpening angles are more durable and reliable in operation compared to segments where the sharpening angle of the tooth tip

20 равен углу заточки впадины.20 is equal to the angle of sharpening the depression.
