Abstract
1. Шкворневая система устройства, перемещающегося по рельсам, и соединяющая ходовую тележку с несущей рамой, содержащая пятник и подпятник, контактирующие по опорной и упорной поверхностям, отличающаяся тем, что на упорной и опорной поверхностях пятника и подпятника предусмотрены выемки, заполненные смазочным материалом, глубиной не менее величины допустимого износа по нормали, при этом угол, образованный краями двух рядом расположенных выемок в радиальном направлении не превышает угла поворота тележки в кривых участках пути, а соотношение площадей опорной или упорной поверхностей к соответствующей суммарной площади расположенных на них выемок удовлетворяет условию: ! ! где σ, [σ] - соответственно номинальные и допустимые напряжения, ! F - нормальная сила, ! А, А1 - соответственно площадь поверхности и суммарная площадь выемок на ней. ! 2. Шкворневая система по п.1, отличающаяся тем, что указанные выемки заполняются твердым смазочным материалом. ! 3. Шкворневая система по пп.1 и 2, отличающаяся тем, что указанные выемки заполняются консистентным смазочным материалом.1. The pivot system of the device moving on rails and connecting the undercarriage with the supporting frame, comprising a Friday and a thrust contacting on the supporting and thrust surfaces, characterized in that recesses are provided on the thrust and supporting surfaces of the Friday and thrust bearing, the depth not less than the normal allowable wear, while the angle formed by the edges of two adjacent recesses in the radial direction does not exceed the angle of rotation of the cart in the curved sections of the path, and the ratio areas of the support or abutment surfaces corresponding to the total area of the recesses located on them satisfies the condition: ! where σ, [σ] are the nominal and permissible stresses, respectively! F - normal force! A, A1 - respectively, the surface area and the total area of the recesses on it. ! 2. The pivot system according to claim 1, characterized in that said recesses are filled with solid lubricant. ! 3. The pivot system according to claims 1 and 2, characterized in that said recesses are filled with grease.
