Abstract

A finishing monoblock with optimised transmission ratio for a billet rolling plant comprises a plurality of rolling stands (G 1 -Gn) arranged in sequence suitable for forming a rolling line and actuated by a pair of mechanical transmissions ( 11, 12 ) in which bevel gear pairs are foreseen for the variation of ratio in the stands of the rotation speed of rolling cylinders ( 18 ). According to the invention, such a variation of the ratio in the stands is carried out through the combination of a first type (A, B) of bevel gear pairs with a second type of bevel gear pairs (C, D) and there is a set of four of cylindrical gears suitable for making four stands (C, D) with the same transmission bevel gear pair.

Claims (6)

1. Отделочный моноблок с оптимизированным передаточным отношением для агрегата для прокатки заготовок, содержащий множество прокатных клетей (G1-Gn), расположенных последовательно для образования прокатной линии и приводимых в действие двумя механическими трансмиссиями (11, 12), в которых предусмотрены конические зубчатые пары для изменения передаточного отношения в клетях скорости вращения прокатных цилиндров (18), отличающийся тем, что указанное изменение передаточного отношения в клетях осуществляется посредством комбинации конических зубчатых пар первого типа (А, В) и конических зубчатых передач второго типа (C, D), при этом имеется группа из четырех цилиндрических зубчатых передач, позволяющая иметь четыре клети с одинаковыми трансмиссионными коническими зубчатыми парами (C, D).1. Finishing monoblock with optimized gear ratio for the unit for rolling workpieces, containing a lot of rolling stands (G1-Gn) arranged in series to form a rolling line and driven by two mechanical transmissions (11, 12), in which bevel gear pairs are provided for changes in the gear ratio in the stands of the rotation speed of the rolling cylinders (18), characterized in that the said change in the gear ratio in the stands is carried out by means of a combination of conical gear pairs of the first type (A, B) and bevel gears of the second type (C, D), while there is a group of four cylindrical gears that allows you to have four stands with identical transmission bevel gear pairs (C, D). 2. Отделочный моноблок с оптимизированным передаточным отношением по п.1, отличающийся тем, что для моноблока из десяти клетей (G1-G10) суммарное передаточное отношение составляет 5,6907497, из которого передаточное отношение, определяемое различием между передаточными отношениями групп из четырех цилиндрических зубчатых передач, равно 1,5454545, так что остается распределить передаточное отношение, равное только 3,6822498.2. Finishing monoblock with an optimized gear ratio according to claim 1, characterized in that for a ten-stand monoblock (G1-G10), the total gear ratio is 5.6907497, of which the gear ratio is determined by the difference between the gear ratios of groups of four cylindrical gears gears is equal to 1.5454545, so it remains to distribute the gear ratio, equal to only 3.6822498. 3. Отделочный моноблок с оптимизированным передаточным отношением по п.1, отличающийся тем, что дифференциация группы из четырех зубчатых передач обеспечивает получение группы из двух клетей, имеющей оптимизированные промежуточные клети с передаточным отношением, очень близким к 1:1, предпочтительно близким к 1,244898 и 0,8032786.3. Finishing monoblock with an optimized gear ratio according to claim 1, characterized in that the differentiation of the group of four gears provides a group of two stands having optimized intermediate stands with a gear ratio very close to 1: 1, preferably close to 1, 244898 and 0.8032786. 4. Отделочный моноблок по п,1, отличающийся тем, что для моноблока из восьми клетей (G1-G8) суммарное передаточное отношение составляет около 3,682249, из которого передаточное отношение, определяемое группами из четырех зубчатых передач, составляет около 1,5454545, а для конических зубчатых передач остается распределить только передаточное отношение, близкое к 2,965602.4. Finishing monoblock according to claim 1, characterized in that for a monoblock of eight stands (G1-G8), the total gear ratio is about 3.682249, of which the gear ratio, determined by groups of four gears, is about 1.5454545, and for bevel gears, it remains to distribute only a gear ratio close to 2.965602. 5. Отделочный моноблок по п.4, отличающийся тем, что для второй и третьей групп из двух клетей конические зубчатые пары идентичны, что позволяет для всех восьми клетей использовать конические зубчатые пары только двух типов вместо четырех типов, как в уровне техники.5. The finishing monoblock according to claim 4, characterized in that for the second and third groups of two stands the bevel gear pairs are identical, which allows for all eight stands to use bevel gear pairs of only two types instead of four types, as in the prior art. 6. Отделочный моноблок по п.1, отличающийся тем, что для него требуется иметь в качестве запасной трансмиссию только одной клети с двумя комплектами подшипников и коническими зубчатыми парами двух типов.6. The finishing monoblock according to claim 1, characterized in that it requires only one stand with two sets of bearings and two types of bevel gear pairs as a spare transmission.
