Outboard Hydrostatic Bearing Assembly for Can Bodymaker

摘要

A hydrostatic/hydrodynamic fluid bearing assembly for a can bodymaker is provided. The hydrostatic/hydrodynamic fluid bearing assembly is separate from the ram body. The outboard guide bearing assembly includes a carriage assembly and a number of elongated journals. The carriage assembly includes a ram coupling, a crank coupling, and body defining a number of journal passages. The ram body is coupled to a ram coupling. The crank coupling is structured to be coupled to a crank arm. Each journal extends through a carriage assembly body journal passage. In this configuration, the ram body may form a can body in a traditional manner, but fluid bearing assembly fluid is not applied to the ram body. Instead, the fluid bearing assembly fluid is applied to the journals.
