Title:
IMPROVED ACTIVATION MECHANISM FOR A LIQUID COOLED RACK
Document Type and Number:
WIPO Patent Application WO/2012/054884
Kind Code:
A3
Abstract:
A cam shaft is fitted with one or more sleeve bearings to negate friction between the rotating cam shaft and a surface onto which the cam shaft is rotated. A metal sheet is bent upward or downward by rotating cam shafts from a first position to either a second position or a third position. Rotating a cam shaft from the first position to either the second or the third position forces an offset portion of the cam shaft against a side of a U-bend in the metal sheet. The rotation generates a normal force against the U-bend that is translated to a bending of the metal sheet. The rotation also generates a tangential force. The sleeve bearings negate friction that may be generated by the tangential force.
