Abstract
1. Устройство для поперечно-винтовой прокатки трубчатого или пруткового прокатываемого материала, содержащие два или более приводных прокатных валка (2), вращающихся вокруг продольной оси (3) прокатываемого материала (1), при этом оси (4) прокатных валков имеют наклон относительно продольной оси (3) прокатываемого материала (1), причем для осуществления подачи прокатываемого материала (1) наклонные оси (4) валков (2) проходят в тех плоскостях, которые, если смотреть в направлении продольной оси (3) прокатываемого материала (1), располагаются параллельно продольной оси (3) прокатываемого материала (1), рядом с ней и на некотором радиальном удалении (Е) от нее, при этом ведущая шестерня (9), окружающая соответствующую ось (4) валка (2), с помощью конических шестерен (11) входит в зацепление с солнечной шестерней (10), окружающей продольную ось (3) прокатываемого материала (1), причем средняя ось ведущей шестерни (9) лежит в плоскости, в которой располагается и продольная ось (3) прокатываемого материала (1), при этом ведущая шестерня (9), входящая в зацепление с солнечной шестерней (10) имеет в области ступицы внутреннее зацепление (40), с которым взаимодействует внешнее зацепление (41) вала (8), несущего соответствующий прокатный валок (2) и установленного со смещением осей относительно средней оси ведущей шестерни (9) таким образом, что она имеет наклон в тех плоскостях, которые, если смотреть в направлении продольной оси (3) прокатываемого материала (1), располагаются параллельно продольной оси (3) прокатываемого материала (1), рядом с ней и на некотором радиальном удалении (Е) от нее. ! 2. Устройство по п.1, отличающееся тем, что вал (8), несущий соответствую1. A device for the cross-helical rolling of a tubular or bar rolling material, containing two or more drive rolling rolls (2), rotating around the longitudinal axis (3) of the rolled material (1), while the axis (4) of the rolling rolls are inclined relative to the longitudinal axis (3) of the rolled material (1), and for feeding the rolled material (1) the inclined axes (4) of the rolls (2) extend in those planes which, when viewed in the direction of the longitudinal axis (3) of the rolled material (1), parallel on the longitudinal axis (3) of the rolled material (1), next to it and at a certain radial distance (E) from it, while the drive gear (9) surrounding the corresponding axis (4) of the roll (2) using bevel gears ( 11) engages with the sun gear (10) surrounding the longitudinal axis (3) of the rolled material (1), and the middle axis of the pinion gear (9) lies in the plane in which the longitudinal axis (3) of the rolled material (1) is also located while the drive gear (9), which engages with the sun gear (10), has in the hub area internal gearing (40), with which the external gearing (41) of the shaft (8) interacts, bearing the corresponding rolling roll (2) and installed with an axis offset relative to the middle axis of the pinion gear (9) so that it has an inclination in those planes which, when viewed in the direction of the longitudinal axis (3) of the rolled material (1), are parallel to the longitudinal axis (3) of the rolled material (1), next to it and at a certain radial distance (E) from it. ! 2. The device according to claim 1, characterized in that the shaft (8) bearing the corresponding
