Description
Известны двухшарнирные режущие цепи дл горных машин, в которых двойной шарнир выполнен таким образом, что он воспринимает большую кзгибаюшую нагрузку, в результате чего цепи имеют невысокую прочность.Double-hinged cutting chains for mining machines are known, in which the double hinge is designed in such a way that it takes up a large bending load, as a result of which the chains have a low strength.
Цель изобретени - разгрузка цилиндрического хвостовика от изгибающих напр жений шарнира.The purpose of the invention is the unloading of a cylindrical shank from bending stresses of a hinge.
Предлагаема шарнирна цепь отличаетс от известных тем, что серьга двойного шарнира выполнена с буртиком, расположенным концентрически относительно -оси цилиндрического хвостовика.The proposed hinge chain differs from the known ones in that the double hinge shackle is made with a collar located concentrically with respect to the axis of the cylindrical shank.
На фиг. 1 показана предлагаема цепь, вид сбоку, в плане и поперечный разрез ; на фиг. 2 - серьга двойного шарнира с цилиндрическим хвостовиком и буртиком.FIG. 1 shows the proposed chain, side view, in plan and cross section; in fig. 2 - double hinge earring with cylindrical shank and collar.
Предлагаема цепь содержит кулак 1, промежуточный кулак 2, валик 3, замок 4 двойной шарнир 5, стопорный винт 6.The proposed chain contains fist 1, intermediate fist 2, roller 3, lock 4 double hinge 5, lock screw 6.
Наличие бурта 7 позвол ет разгрузить хвостовик 8 шарнира от изгибающих нагрузок , возникающих от консольного приложени т говых усилий, благодар чему новы- The presence of the collar 7 allows you to unload the shank 8 of the hinge from bending loads arising from the cantilever application of pulling forces, thanks to which new
шаетс прочность цепи и значительно упрощаетс ее конструкци .The strength of the chain is shorter and its structure is considerably simplified.
В продольном направлении цепь уравновешена упором кулаков друг в друга, что уменьшает силы трени цепи о направл ющие бара. Дл уравновешивани цепи в поперечном направлении кулаки имеют широкие опорные поверхности, опираюшиес на закаленные планки, прикрепленные по всей длине щек бара. Конструкци цепи позвол ет выполн ть раму бара из сталей, термически не обработанных.In the longitudinal direction, the chain is balanced by placing the fists against each other, which reduces the strength of the chain against the bar guides. In order to balance the chain in the transverse direction, the fists have wide bearing surfaces supported on hardened strips attached along the entire length of the cheeks of the bar. The chain construction allows the bar frame to be made from steels not thermally treated.
