Abstract

The invention relates to a divided flow type master transmission reduction gear box of a hot rolling mill. The box bodies of the reduction gear box comprise an upper box body, a middle box body and a lower box body; the output shafts of the reduction gear box comprise a long output gear shaft and a short output gear shaft; two independent drive systems with the same structures and parameters are symmetrically located on the two sides of the long output gear shaft; the short output gear shaft is supported between the upper box body and the middle box body through a bearing; the long output gear shaft and shafts in the independent drive system are supported between the middle box body and the lower box body through the bearing; the independent drive system comprises an input gear shaft and a middle gear shaft; a high and low speed gearshift mechanism is arranged on the middle gear shaft; a high and low speed shift gear in the high and low speed gearshift mechanism is engaged with a high and low speed gear in the input gear shaft; an output gear is mounted on the long output gear shaft through a key; a gear on the middle gear shaft is engaged with the output gear on the long output gear shaft; the gears on the long output gear shaft and the short output gear shaft are mutually engaged; and the high and low speed gearshift mechanism is arranged on the middle gear shaft and is synchronously adjusted through a synchronous gearshift device.

Description

technical field [0001] The invention relates to a hot-rolling main drive reduction gearbox, in particular to a main drive reduction gearbox for a split flow hot rolling mill. Background technique [0002] The main drive reduction gearbox is one of the key equipment in the hot rolling equipment of non-ferrous metals. In the hot rolling field of non-ferrous metals, the hot rolling main drive reduction gearbox is generally driven by one motor at the same time. Two output shafts , this single-input and double-output working mode, for the high-power hot-rolled main drive reduction gearbox, not only needs to be equipped with a relatively high-power motor, but also each transmission gear, especially the input gear shaft needs to have a large mechanical strength. For this reason, the high-power hot-rolled main drive reduction gearbox is improved. The two outputs are separately driven by independent transmission systems, and the transmission mode of double input and double output is...
