Bell-crank lever arrangement - for holding and smoothly adjusting rollers in chocks, particularly in three-high roll stands

摘要

Rollers in chocks are held axially and smoothly adjusted by a bell-crank lever arrangement with pivoted bell-crank levers acting against each other and pressing against chock shoulders. There are also two bell-crank levers which take effect in the same axial direction and are connected adjustably with each other outside the roller axis by a grip spring tensioning member. Each of these bell-crank levers can be braced against a respective bell-cank lever acting in an opposite direction to the axial by an adjusting member.
