What is the main application of Gearbox used for rolling mills?
Gearbox used for rolling mills is an important equipment in the main transmission device of a rolling mill. It has two main functions. One is to increase the low torque of the motor by a certain proportion to the high rolling torque required by the rolling mill when rolling steel. One is to convert the motor speed through a certain speed ratio into the rolling speed required by the rolling mill when rolling steel to meet the requirements of the steel rolling process. Therefore, the running state of the main transmission gearbox of the rolling mill directly affects the normal production of the entire rolling line.
Gearbox used for rolling mills has a wide range of types and applications, mainly through the meshing and transmission of gears to achieve acceleration, deceleration, change the transmission direction, change the rotation torque or distribute power to meet the power transmission needs of various metallurgical equipment. Gearbox used for rolling mills is not only used for various host equipment, such as main transmission gearboxes for rough rolling, finishing and vertical rolls of rods and wires, profiles or plates, but also used for many auxiliary equipment transmission systems, such as flying shears, Coilers, punches, slitters, conveyor raceways, etc.
As one of the most critical rolling mill equipment, the stable and reliable operation of Gearbox used for rolling mills is related to the normal operation of the entire production line. If it fails, it will cause serious consequences. Gearbox used for rolling mills are usually in harsh operating environments such as heavy load, shock load, high or low speed, high temperature or high pollution. It is precisely because of the particularity of the working environment and continuous and reliable work requirements, Gearbox used for rolling mills The bearings put forward more stringent requirements.
The use of high-performance bearings, the correct selection of bearing selection, tolerance matching, initial clearance and installation dimensions are the prerequisites for ensuring the continuous and reliable operation of Gearbox used for rolling mills.
