Fine-machining method for crowned tooth flanks on, in particular hardened, gears

摘要

A fine-machining method for crowned tooth flanks of, in particular hardened, gears with two-flank contact and crossed axes using an abrasive gear-shaped or rack-shaped tool is presented in which the tool performs relative to the workpiece several reciprocating feed movements, not entirely sweeping over the workpiece, in a direction (X) running at an angle ( epsilon ) oblique to the workpiece axis (4) and an infeed movement (Z) for reducing the centre distance. The tool has uncorrected teeth. The crowning is produced only at the end of the fine machining, during at least one reciprocating feed movement without infeed movement, which completely sweeps over the workpiece. <IMAGE>
