Machined Feature to Reduce Grinding Transition Zone Width between Adjacent Lobes of an Assembled Lobe Pack

摘要

When two adjacent lobes are ground in sequence, the grinding wheel needs to stay clear of the edge of the adjacent lobe with a clearance width. Current art is to do a rough cut of the side of each lobe before the finish grind operation. With two adjacent lobes splayed at an angle, the total clearance zone needed is doubled. The present invention is a product design that is used in a sliding cam system. The claim is a machined feature 1 on the side of the lobe of an assembled lobe pack 2 where two or more adjacent lobes 3 and 4 arc pressed together.
