Transmission device of top cross 45-degree continuous rolling machine unit

Abstract

The invention provides a transmission device of a top cross 45-degree continuous rolling machine unit. The transmission device comprises a reversing speed changing distribution device provided with two output shafts, rotating center lines of the two output shafts are both arranged perpendicular to the rotating center line of an input shaft, the rotating center line of the input shaft is perpendicular to the rolling center line of the top cross 45-degree continuous rolling machine unit, and the two output shafts are respectively connected with input shafts of a pair of driven bevel gear boxes of an adjacent machine frame. The transmission device further comprises a driving motor arranged on one side of the rolling center line of the top cross 45-degree continuous rolling machine unit, the rotating center line of an output shaft of the driving motor is arranged perpendicular to the rolling center line of the top cross 45-degree continuous rolling machine unit, and the output shaft is connected with the input shaft of the reversing speed changing distribution device. In the transmission device of the top cross 45-degree continuous rolling machine unit, the driving motor is arranged on one side of the rolling center line and is good in working environment and convenient to maintain.

Description

Technical field [0001] The invention relates to a transmission device for a top cross 45° continuous rolling unit, which is suitable for finishing and pre-finishing rolling units of bars and wire rods, and belongs to the field of steel rolling machinery. Background technique [0002] The metal wire rod needs to be rolled after casting the blank, and usually requires multiple sets of rolling mills for continuous rolling, and the cross section of the wire rod is also continuously reduced. In recent years, high-speed wire rod continuous rolling mills have widely adopted top cross 45° continuous rolling mills as finishing mills and pre-finishing mills. Such as figure 1 with figure 2 As shown, the existing high-speed wire rod top cross 45° continuous rolling mill as a finishing mill usually includes a base and 10 racks fixed on the base. The rolls of the 10 racks form a top cross 45° with the horizontal rolling centerline. ° Alternate arrangement. Such as figure 1 As shown, the tra...
