Description

Technical Field

[0001] This utility model relates to the field of roll transmission technology, and in particular to a roll transmission mechanism for a thin strip mill. Background Technology

[0002] In the metal processing industry, strip mills are key equipment for producing high-precision thin strip materials. Their performance and precision directly affect the quality of the final product and production efficiency. The roll drive mechanism, as a core component of the strip mill, is responsible for efficiently and accurately transmitting the power of the drive motor to the rolls to achieve continuous and uniform rolling of metal materials. These issues are particularly prominent regarding the transmission method between the rolls and the drive motor.

[0003] In traditional designs, a cross coupling is typically used to transmit power between the rolls and the drive motor. In practical applications, the length of the cross coupling is fixed. Since the cross coupling is installed between the motor and the rolls for transmission, the distance between the rolls and the drive motor must be precisely calculated and strictly controlled to ensure that the cross coupling can connect the two accurately. If the measured distance error is large, the cross coupling cannot connect the motor and the rolls. This requirement not only increases the complexity and time cost of the installation process but also places extremely high demands on installation accuracy, making installation difficult. Even a small deviation in the measured distance can prevent the cross coupling from being installed smoothly, thereby affecting the transmission efficiency and stability of the entire rolling mill system, resulting in extremely low tolerance.
