Method for producing bevel gears having hypocycloidal teeth in the continuous forming method using corresponding tools

摘要

#CMT# #/CMT# The method involves milling tooth spaces of a ring gear (32) by machining a ring gear blank (32) by a milling tool (50) that is displaced in rotation around a measuring head axis (51) of the milling tool. The tool is defined by a conical virtual generating gear (41) that corresponds to an inverted cone shape of the ring gear. Hypocycloids e.g. straight hypocycloids or rectilinear hypocycloids, are produced as longitudinal flank lines during milling of the ring gear, where rotation of the tool and the tool axis and rotation of the gear blank and a workpiece axis (33) are coupled. #CMT#USE : #/CMT# Method for manufacturing ring gears for a bevel wheel e.g. spur-toothed bevel wheel, straight-cut bevel wheel and spiral-toothed bevel wheel. #CMT#ADVANTAGE : #/CMT# The hypocycloids e.g. straight hypocycloids or rectilinear hypocycloids, are produced as the longitudinal flank lines during milling of the ring gear, where rotation of the tool and the tool axis and rotation of the gear blank and the workpiece axis are coupled, thus enabling manufacturing of bevel wheel pairs made of spur-toothed pinion and spur-toothed ring gear in a fast manner, and avoiding the need for machines for producing spur toothing. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation illustrating a method for manufacturing ring gears. 32 : Ring gear 33 : Workpiece axis 41 : Conical virtual generating gear 50 : Milling tool 51 : Measuring head axis of milling tool.
