Abstract

The invention relates to a rolling mill gear box with high-low speed output, comprising a first gear shaft, a first output shaft, a second gear shaft, a second output shaft and an input shaft which support on a box by bearings; the first gear shaft is provided with a big bevel gear and a first hollow gear shaft supported by the bearings; the first hollow gear shaft is provided with a second transmission gear; the first output shaft is provided with a first output gear and a second hollow gear shaft supported by the bearings; the second hollow gear shaft is provided with a first transmission gear; the second output shaft is provided with a second output gear; the output shaft is provided with a bevel pinion; the bevel pinion on the output shaft is meshed with the big bevel gear; the first hollow gear shaft is meshed with the first output gear; the second hollow gear shaft is meshed with the second transmission gear; the first transmission gear is meshed with the first gear shaft and the second gear shaft at the same time; and the gear in the second gear shaft is meshed with the second output gear.

Description

technical field [0001] The invention relates to a gear box, especially a rolling mill gear box with high and low speed outputs. Background technique [0002] In the process of realizing power conversion, the gearbox plays a very important role. With the development of science and technology, people continue to put forward new requirements for power conversion, and various forms of gearboxes have emerged according to different needs. [0003] At present, the two output shafts of the gearboxes used in rolling mills generally have the same speed. However, to meet the technical requirements of special rolling mills that require different speeds between the two output shafts, the design often needs to be arranged step by step according to the traditional gears. If the speed difference between the two output shafts is more than ten times, it will inevitably lead to a larger volume of the gearbox and need to occupy a larger installation space.
