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.

Multi-axis generating motion modifies each gear tooth flank to cut psychoacoustic noise without tooth thickness or indexing errors.

Reciprocal flat-support motion moves gear-cutting chips to collection points, reducing manual clearance and maintenance interruptions.

Independent correction of gear machining control elements helps match crowning, bias, and other tooth targets with less trial and error.

Phase correction angles let one gear cutting tool machine both tooth side surfaces at a fixed intersection angle, cutting tool changes, wear, and tact time.

Two grinding tools in one NC clamping cycle form precise gear tip edge roundings, remove burrs, and preserve tooth flank accuracy.

Angularly offset gear halves let the hobbing tool reach adjacent tooth gaps, fully machining double-helical teeth without extra gear width.

A two-tool single-chucking grinding sequence forms precise gear head edge roundings, avoids re-chucking errors, and prevents burrs.

Opposing axial feed turns gear peeling from pushing to pulling, reducing chip jamming and improving tooth-space surface quality.

A movable counterholder clears interference contours and working space limits, enabling accurate switching between gear milling and skiving.

Angularly offset tooth halves let a skiving wheel reach apex regions, cutting double helical gears with less width and shorter machining time.

Stationary spindles at separate locations enable parallel gear hobbing and deburring, eliminating idle time for the primary cutter during secondary operations.

Segmented deburring passes with varying inclination angles remove secondary burrs without generating tertiary defects in continuous production.

Inverting the workpiece chuck above the shaving cutter uses gravity to remove shavings, resolving accuracy loss from debris accumulation on gear teeth.

A CNC deburring tool uses inverse hypocycloid coupling to guide cutting edges along tooth gaps.
