Gear-Cutting Machines TRIZ Cases

Separate grinding and polishing stations with dynamic wheel positioning cut gear flank finishing time while improving surface smoothness.

A shifted grinding reference position enables precise gear end reliefs with one large-diameter tool, avoiding excess machining and tool changes.

Pattern matching of measured tooth angles identifies gear references without added markings, cutting machining time while preserving angular accuracy.

Measured angular distances identify the reference tooth for hard finishing, avoiding marking steps and extra detection equipment.

Sensor signals screened against tolerance limits flag gear machining errors early, sending only suspect parts to extra measurement.

Shifting the grinding reference position reduces bite depth at gear tooth ends, enabling precise end reliefs without tool changes or small wheels.

Swiveling the generating cutting tool aligns the contact line and cuts extra-stroke, speeding thin-gear lead crowning while preserving tool life.

A cup-shaped clamp places an oscillating mass, springs, and damping elements outside the ring gear opening to suppress machining vibration marks.

Variable workpiece speed keeps cutting volume steadier during gear-edge chamfering, improving accuracy, machining speed, and finger mill life.

A fixed cutter and adjustable workpiece rotation keep worm shaft teeth uniformly deep and aligned to the worm wheel center, avoiding post-machining.

Non-periodic tooth flank modifications from grinding or hard skiving cut tonal gear noise while preserving indexing and concentricity.

A first gear establishes the machining angle, letting identical workpieces skip stock-dividing and cut idle time by up to 25%.

Separating gear grinding and flank polishing lets a robot-polishing cell run in parallel, improving machine use and surface smoothness.

A fixed pallet and gripper orientation lets identical gear workpieces reuse one stock-dividing adjustment, cutting idle time and cycle length.
