Abstract

The invention discloses a motor assembly special for a six-roller invertible rolling mill. The motor assembly is formed in such a way that a primary speed reducer is connected with an upper roller primary motor and a lower roller primary motor through a coupler, the lower roller primary motor is connected with an assembly of a transmission shaft and the coupler through the coupler, the coupler and the assembly of the transmission shaft and the coupler are connected with a lower roller secondary motor, the primary speed reducer is downwards connected with the upper roller primary motor through the coupler and the assembly of the transmission shaft and the coupler, and the upper roller primary motor is connected with an upper roller secondary motor through the coupler and the assembly of the transmission shaft and the coupler so as to be assembled into a whole. The invention has the advantages of reasonable design, convenience for use and enhancement in production efficiency .

Description

Technical field [0001] The invention relates to a special motor unit structure for a rolling mill, in particular to a special motor unit structure for a 1050-type six-roller reversible rolling mill, which is suitable for the 1050-type steel rolling mill. Background technique [0002] At present, the main drive motor of the 1050 type six-high reversible rolling mill is driven by a DC motor for each of the upper and lower rolls. The motor power is 1250kw and the rated current is 2010A. During the rolling process, the motor current is too large, so that the During the 3rd pass, the rolling speed is too slow, which seriously affects the production capacity of the equipment. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a special motor unit structure for a 1050-type six-high reversing rolling mill. The structure of the special motor unit is not only reasonable in design, compact...
