Straight-tooth bevel gear grinding machine - has disc sliding axially to grind both tooth flanks

摘要

The gear tooth flanks are ground by a rotary disc whose spindle is mounted on a reciprocating support, while the work is mounted on a cradle coupled to the spindle carrying it. The grinder disc has a cylindrical peripheral face enclosed by chamfered faces on either side, and can be adjusted in the axial direction, and the cradle is so coupled to the work spindle that as the disc slides axially, cradle and spindle rotate in opposite directions about their axes. Thus one tool machines both tooth flanks in one set up. The disc spindle can be mounted and rotate in a sleeve, to which reciprocating movement is imparted by rams in the axial direction.
