DEVICE AND METHOD FOR PROCESSING BEVEL GEARS WITH DIVISION ERROR COMPLETELY COMPENSATED Russian patent published in 2011 - IPC B23F9/08 B23F23/10 B23F23/12 

FIELD: process engineering.

SUBSTANCE: proposed device comprises part spindle, tool spindle and multiple drives for bevel gear machining. To increase precision of gear wheels, said device is equipped with measurement system connected therewith via interface that receives corrections or correction factors from measurement system in the form that allows adapting reference or mean data prestored in device memory prior to machining one or several bevel gears. Proposed method comprises presetting reference or mean data describing bevel gear shape for its commercial production, and machine tool kinematics. It comprises machining one tooth space between trial billet and relative displacement of tool and said trial billet to remove tool from said space. Trial billet is revolved to another angular position for another tooth space to be machined by repeating above jobs. Note here that said jobs are repeated unless all tooth spaces are machined to for trial billet to be shifted into measurement system to define division error for all trail billet teeth. It comprises also determination of corrections for each tooth or tooth space. Note also that one tooth or tooth space is used as reference tooth or tooth space. It comprises also transmission or reception of corrections and adaptation of machine tool data for production of at least one bevel gear with compensated division errors. Finally, it comprises finishing at least one bevel gear with compensated division errors using adapted machine tool data. Note here that said jobs are repeated unless all spaces and teeth are machine with compensated division errors.

EFFECT: higher precision of bevel gears.
