Description

Technical Field

[0001] The invention relates to the technical field of gear boxes, and in particular to a high-alloy titanium steel rolled gear box. Background Art

[0002] A gearbox is a mechanical transmission device used to change speed and torque. It is widely used in various industrial equipment, including metallurgy, machinery, chemical industry, transportation and other fields. Its main function is to transmit the motion of the input shaft to the output shaft through the meshing of a series of gears, and to achieve changes in speed and torque in the process.

[0003] At present, most gearboxes on the market are made of ordinary alloy steel materials, and the rolling process is relatively mature, but its performance can no longer fully meet the needs of modern industry, especially the metallurgical industry rolling equipment for high strength and high wear resistance. Although ordinary alloy steel has certain strength and toughness, it is prone to fatigue and wear problems under extreme conditions, such as high temperature, high load, strong corrosion, etc., which directly affect the service life of the gearbox and the stable operation of the equipment. In order to solve these problems, high-alloy materials, such as high-alloy titanium steel, are now commonly used to manufacture gearboxes. High-alloy titanium steel is considered to be an ideal material to replace ordinary alloy steel due to its excellent mechanical properties, high temperature resistance and corrosion resistance.

[0004] Although high alloy titanium steel materials can theoretically significantly improve the service life and reliability of gearboxes due to their excellent performance, there are still some technical and design challenges. Most existing gearboxes do not have the function of adjusting the transmission ratio, which makes it impossible to flexibly adjust the transmission ratio of the gearbox to adapt to different load and speed requirements under different working environments, resulting in certain defects in actual use.
