Abstract
A crown adjustment system for a 20-high (1-2-3-4) cluster mill comprising rack-actuated crown adjustment saddles on the F and G backing bearing assemblies. The F and G saddles are equal in number and located in aligned positions so that the gear rings of an aligned F and G saddle pair can be rotated by a single rack for crown adjustment at that saddle position. The mill has a housing affixed to a base having a bottom and supported on a foundation with a trench extending therethrough. The base bottom covers the trench. Each crown adjustment rack is operatively attached to and actuated by its own hydraulic cylinder mounted within the trench on the base bottom. Each cylinder is provided with a sealing assembly enabling replacement or repair of the cylinder without oil drainage from the base. The F and G shafts are provided with at least one aligned pair of screwdown gears actuated by a screwdown rack attached to a rod actuated by at least one hydraulic screwdown cylinder. The at least one screwdown cylinder is located on one of the mill housing, the base bottom within the trench or a pedestal mounted on the base bottom within the trench.
