ных и изгибных колебаний, компенсированы напр жени ми предварительного сжати , поэтому опасные раст гивающие напр жени  устранены. Наличие предварительного сжати  штока исключает по вление раст гивающих напр жений , замен   их сжимающими, и обеспечивает повышение долговечности работы щтока. Формула изобретени  1.Шток молота, отличающийс  тем, что, с целью повыщени  срока службы, он выполнен предварительно сжатым. bending and flexural vibrations, compensated for by prestressing stresses, therefore, dangerous tensile stresses are eliminated. Pre-compression of the stem eliminates the occurrence of tensile stresses, replacing them with compressive stresses, and provides for improved durability of the brush. Claims of the invention 1. A hammer rod, characterized in that, in order to increase the service life, it is made precompressed. 2.Шток молота по п. 1, отличающийс  тем, что в нем выполнены осевые отверсти . в которые вставлены предварительно раст нутые элементы из материала с прочностными характеристиками превышающими аналогичные характеристики материала штока, при этом концевые части элементов соединены с концевыми част ми штока. 2. A hammer rod according to claim 1, characterized in that axial bores are made therein. Into which are pre-stretched elements of material with strength characteristics exceeding those of the material of the rod material, the end parts of the elements are connected to the end parts of the stem. 3.Шток молота по пп. 1 и 2, отличающийс  тем, что предварительно раст нутые элементы выполнены в виде стержней. 3. Hammer rod on PP. 1 and 2, characterized in that the pre-stretched elements are made in the form of rods. 4.Шток молота по пп. 1 и 2, отличающийс  тем, что предварительно раст нутые элементы выполнены в виде набора из проволоки или ленты. Источники информации, прин тые вр внимание при экспертизе: 1. Авторское свидетельство СССР № 479557, кл. В 21 J 13/00, 1973.4. Hammer rod on PP. 1 and 2, characterized in that the pre-stretched elements are made as a set of wire or tape. Sources of information taken by the time of attention during the examination: 1.
