    A round link chain having vertical links with a smaller pitch than the horizontal links. The combined pitch of each vertical link and horizontal link in the configuration of a size 42 round link chain corresponds to the combined pitch of two chain links of a size 38 round link chain, so that in consideration of the stout vertical links, it is possible to use a size 42 round link chain in place of a size 38 round link chain in conventional chain scraper conveyors with limited height of passage for the carrying run and the slack run, and this without altering the pitch diameter of the chain sprockets.

    The invention relates to a conveyor construction, namely a circular circular link chain. Scraper conveyors.
    The purpose of the invention is to increase the reliability of the round link chain and ensure its engagement with asterisks con-.

    A circular chain, for example, for a single-chain scraper conveyor contains vertical 1 and horizontal 2 links, each of which has two parallel straight sections 3 and two arc sections 4. At the same time, the arc sections 4 of each vertical link 1 are made with a circular cross section (Fig. 5). ), and its straight portions 3 are located in the middle parts with a rectangular cross section of the “Step t vertical; links 1 less than the pitch tj of horizontal links 2o Sum.page vertical pitch 1 and horizontal 2 links corresponds to the total pitch of two standard links of the same chain size of the lower order, Tooo links with a smaller bar diameter about B vertical links x 1 area cross sections Q of arc sections 4 are larger than the square of the cross section Qc of the straight section: 1

    In addition, for the vertical link 1, the arc sections 4 have a variable cross section, which in verlhinum S has the greatest value, and from the top S, sections 4 are uniformly transferred into. Straight plots 3 The top S of each link 1 is located in its horizontal plane of symmetry. Here is the line: the curved sections 3 and / or arc sections 4 of each vertical link 1 have a flat; the cross section of Q is larger than the flat, of the cross section of each bar horizontal link 2 „
    Vertical links 1 have in the zone of their arc sections 4 zakpyrglenn o the inner surface 5, the straight line sections 3 - a rectangular cross section Qg, while the width B of the straight sections 3 is equal to the diameter DQ of the largest cross section of the arc sections 4c the linear sections 3 are equal to the internal diameter D of the arc sections 4 and, moreover, are only slightly larger than the diameter of the circular cross-section of the horizontal bar Z l 34
    Thanks to this, the sections of 3 vertical links 1 in the zone of smooth mating with section 4 form an abutment 6 on both sides, preventing from moving to horizontal links located above the horizontal links 2
    Vertical links form low and short compact links. Horizontal links are long and flat support links for attaching scrapers to them. Since the total pitch of the vertical and horizontal links corresponds to the cumulative pitch of standard chain links that are equal in size but have lower pores. Dca, Toe „weaker, then the proposed round link
    0 chain, even when using reinforced links, can interact with chain sprockets 7 without changing the diameter of their pitch circle B -, -, mn with such asterisks, which are designed for weaker links. It requires only an increase in notches for horizontal links.

    Horizontal links have a bar diameter of 42 mm, bar width is 138 mm and a pitch of 152 mm, and vertical links have a height of 110 mm bg and a pitch of g 122 mm. Thus, we are talking about the so-called 42nd circular link chain, but with a total step of 274 mm horizontal and vertical links, which is identical to the total step of the 38th circular link in accordance with DIN
    Consequently, the application of the invention allows the replacement of a weaker 38th round link chain to a more powerful 42nd chain without the need to replace chain sprockets or machines' frames. On the contrary, such a replacement does not affect the basic dimensions of the sprockets and standard machine frame rails. flawed chain is capable of transmitting significantly higher tractive forces. Vertical links make it so flat that it is possible to use the chain in the usual conveyor gratings “In addition, longer horizontal links ( compared to 38 minutes chain) causes a lower pressure in udeggnoe recesses chain sprockets, since their support surface ahead of horizontal units x 38-11 Sle5 chain
