Hot-rolled sheet and strip material main drive gearbox

The main drive gearbox for hot-rolled sheet and strip is an important component in the main drive system of the rolling mill. Its functions are mainly two: one is to increase the low torque of the motor to a certain proportion to meet the high rolling torque required for steel rolling of the rolling mill; the other is to convert the motor's rotational speed through a certain speed ratio into the rolling speed required for steel rolling of the rolling mill, in order to meet the requirements of the steel rolling process. Therefore, the operating condition of the main drive gearbox of the rolling mill directly affects the normal production of the entire rolling line. 

Through the successful repair of the bearing chamber wear problem of the main drive gearbox of the steel industry rolling mill, the problem of bearing chamber wear has been fundamentally and effectively solved. Compared with traditional maintenance, it not only saves maintenance time, but also has wide application, low hidden danger risks, is convenient and fast, the operation is simple, and the labor intensity is low. This bearing chamber repair technology has been well applied to the bearing chamber wear problems of various types of gearboxes and reducers in various industries.
