ANORDNING FOR AVRIVNING AV SLIPSKIVOR ENLIGT EN EVOLVENTPROFIL MED INSTELLBAR GRUNDCIRKELRADIE

摘要

A device for dressing a grinding wheel with an involute profile has an involute motion produced by a straight-edge rolling on a curved guide. The dressing tool toolholder is attached to a plate sandwiched between and slidable relative to a lower plate pivoted on the curved guide axis and an upper further plate carrying the straight-edge. A radial arm pivoted on said guide axis engages first and second slider blocks connected to the further and toolholder plates respectively such that the tool also describes an involute, but whose base circle radius is variable by radial adjustment of the second block.
