The Design Of The Main Driver Of 1250 HC Mill
Abstract
This design to the hc mill main drive structure. Main drive system of steel rolling is mainly composed of motor,shaft coupling and frame. This design is carried out on the hc mill main drive system design, including motor.coupling and frame, through the calculation of rolling force can parameter and intensity analysis of the parts to complete the design content. So that the use of design to meet requirements and is reasonably practicable. and then rolling force can be calculated parameters,and in accordance with the results calculated to select the motor and check the calculation, while the main components, such as roller, connecting shaft. transmission shaft and tooth strength and wear resistance of the check to ensure that the use of the safety and reliability, the last of the Lubrication Analysis of a simple manner, on the economy is also analyzed.Considering the cost problem, motor with low cost high speed of ac motor. In the process of design, we should consider the practicality manufacturing difficulty. Economic factors and problems encountered in the actual production. Gear stand: used to transfer torque to work roll. the design USES two equal diameter cylidrical herringbone gear in the vertical plane in a row. packed in the sealed enclosure. Coupling: the gear reducer and connecting shaft of a secure connection. The main motor with plum blossom joint shaft coupling in general.
