Gear Wheels TRIZ Cases
- Spiral Gear Groove Whirling to Reduce End Machining Interference
Synchronized whirling with rolling edge contact cuts spiral gear grooves closer to workpiece ends while reducing chuck interference and waste.
- Gear Whirling With Twisted Axes to Reduce End Undercut
Twisted-axis whirling cuts spiral tooth grooves with less chuck interference, reducing incomplete gear ends while preserving accuracy.
- Segmented Extruder Screw Toothing for High-Torque Durability
Axially spaced gear-ring recesses shift torque away from hub edges, cutting stress peaks and preventing toothing deformation.
- Segmented Extruder Screw Teeth for High-Torque Stress Relief
Circumferential tooth-ring recesses shift torque transfer away from hub edges, reducing stress peaks and plastic deformation.
- Resin Gear End-Face Recesses for Fiber Orientation Control
Asymmetric end-face recesses redirect resin flow during molding to prevent local stress and deformation while improving gear accuracy and strength.
- Cold Forming Tool Slide With Motorized Rack Positioning and Clamping
Motor-driven rack positioning and indirect clamping support forming forces while speeding precise profile distance adjustment in cold forming.
- Cold Forming Tool Slide Control for Precise Profile Setup
Independently driven tool slides set and correct rack reference positions to cut pitch errors, vibration transfer, and setup time in profile forming.
- Spline Rolling Tool Inlet Geometry for Long Profile Forming
An extended rolling-tool inlet and relief area spreads feed force to cut wear and enable longer spline and hollow-shaft profiles.
- Interchangeable Rolling Disc Assembly for Longer Tool Life
A replaceable disc takes most of the rolling load, cutting waste and maintenance while preserving profile precision and tool life.
- Rolling Toothing Profile Forming for Simpler Cold-Press Tooling
A rolling rotational body forms precise toothing profiles with a simpler cold-forming tool, reducing wear and easing tooling changes.
- Cold Rolling Tool Slide With Motorized Rolling Bar Adjustment
Motor-driven carrier positioning replaces manual rolling bar setup, improving profile distance accuracy and forming force stability in cold rolling.
- Helical Gear Cutting with Synchronized Rolling Contact
Synchronized tool and workpiece motion forms precise helical tooth grooves in one pass, cutting cycle time, heat, and extrusion cleanup.
- Gear Tooth Rolling with Dual Shaping Tools for Fatigue Strength
Dual shaping rollers induce compressive residual stresses in gear tooth flanks, improving fatigue strength and surface quality for fast production.
- Thin-Walled Ring Gear Forming With Synchronized Dual Toothing
Synchronized rotary stamping forms inner and outer ring gear teeth in one cold-forming step, cutting weight while preserving dimensional stability.
- Power Skiving Cutter Geometry for Tooth Flank Smoothing
A large edge-rounding radius turns power skiving into chipless tooth flank smoothing, reducing roughness on steel gears in one pass.
- Profile for a rolling tool
A floating-bearing profile part lets a rolling tool self-align, improve outer contour quality, and cut refurbishment cost through easy replacement.
- Stamped Part Embossing for Burr Rounding and Indentation Reduction
A multi-part embossing die rounds stamping burrs and reduces indentation in one stroke, cutting geometric deviation and post-processing.
- Drum-Shaped Gear Forming With Two-Stage Wall Thickness Control
A two-stage flow-forming and toothed-roller process shapes drum gear splines while holding wall thickness, reducing cracks and post-processing.
- Thin-Walled Hollow Gear Wheels With Dual Toothing and Shape Stability
Synchronized radial stamping forms internal and external gear teeth at once, improving hollow wheel precision, shape stability, and weight.
- Multi-Layer Shaped Parts with Integrated Plating and Forming
Combining plating and forming in one step produces bonded multi-layer shaped parts faster while allowing flexible material and thickness selection.
- Gear Toothing Inlet Calibration to Eliminate Forming Overhangs
Axial forming is followed by die and compression-ring calibration to remove gear tooth inlet and outlet overhangs without extra machining.
- Cold Rolling Rack Inclination for Post-Hardening Profile Accuracy
Adjustable rack inclination pre-compensates hardening-induced conical warp so cold-rolled profiles stay within dimensional tolerances.
- Planetary Gear Torsional Damper With Homogeneous Tooth Engagement
Controlled tooth-thickness variation in press-formed planetary gears prevents damage, preserves damping performance, and cuts manufacturing time.
