Abstract

The experience of the Electrostal Heavy Machinery Plant in the design and production of special gearboxes and gear stands for main drive of various rolling mills is summed up. The specifics of rolling and ball-rolling, piercing and reduction mills, mills for cold rolling tube and for the production of reinforcing bars are considered. The load sequence diagram depends both on the range of rolled products, and variable loadings in a rolling cycle of a workpiece. Geometric parameters of gears are optimized by contact and bending equal strength, as between the stages as within each of them. Carburizing, hardening and grinding of teeth are provided and secured technologically.
