V-Belts TRIZ Cases

A widened rocking edge around the convex saddle surface cuts bind-ring sliding friction during element turning, improving CVT belt efficiency.

Twisted polyester cord with controlled thermal shrinkage helps a double-cogged raw-edge V-belt maintain transmission ratio at high temperature.

A satin-weave band fabric removes transverse splice laps in banded V-belts, reducing periodic noise, friction instability, and surface wear.

A continuous multi-stage belt process keeps elastomer layers warm between steps to limit moisture, contamination, and weak bonding.

Crossed ridges embossed during vulcanization increase back-side belt friction for torque transmission while preserving markings and masking flaws.

Signal lines built into the drive belt replace separate trailing cables, cutting maintenance effort and installation space in linear drives.

Inwardly curved belt ribs reduce clamping, friction, wear, and noise during pulley deflection while preserving strong force transmission.

Pre-formed transverse channels let pins join toothed belt ends without drilling, cutting assembly time and avoiding drill breakage.

Curved pillar ends smooth the ring path in a single-ring transmission belt, reducing misalignment contact, stress, and wear.

Variable pulley-groove V angles balance compact wrapping diameter with contact pressure control to extend V-belt life across speed layouts.

A multilayer knitted belt surface combines cellulose, polyamide, and polyester yarns to keep wet friction stable and resist wear over time.

A belt-mounted outer pocket enables precise electronics placement after vulcanization, avoiding heat damage while preserving belt strength.

Mixed fiber tension members with protective jackets help elevator belts balance strength, flexibility, wear resistance, and smooth traction.

Pressure molding below vulcanization fully penetrates elastomer into belt fabric, avoiding solvents, pores, and weak bonding.

A heat-resistant fiber composite on the rib bottom cuts grinding waste while improving belt durability, bending, and appearance.

Optimized cord depth and rib geometry cut bending and compressive losses in a V-ribbed belt while preserving transmission performance.

A fabric-laminated notch top in a wrapped V-belt spreads bending stress to suppress cracks and extend belt life.

Dual hooks and displacement-restriction surfaces let the hoop assemble easily while keeping belt elements engaged under wear and vibration.

Vacuum holds the textile layer to belt mold geometry before elastomer injection, improving bending resistance and tension-carrier bonding.

A low-friction transverse strip covers rib coating ends and the parting line to prevent shear stress spikes and operating noise in drive belts.

An aqueous aromatic resin replaces formaldehyde in power transmission belt adhesion, improving composite endurance without strong agitation.

Localized punch protrusions form recessed and bulging portions to balance CVT metal element thickness, reducing mold load, bending, and wear.

Non-twisted sheeted reinforcing filaments let a transmission V-belt resist lateral pressure while staying flexible and reducing heat generation.

Alternating taller and lighter transverse segments cut CVT belt weight while preserving radial alignment, line contact, and torque transmission.

Controlled nitriding and selective shot peening balance residual stress, hardness, and ductility in CVT steel rings to improve fatigue life.

Winding and connecting cord segments distribute belt tension more effectively, increasing strength while simplifying pulley installation and removal.

Wax on the belt contact surface and width-oriented short fibers cut friction, improve slidability, and maintain durability under high load.

A satin-weave fabric wrap cuts transverse splice-lap noise and vibration while stabilizing belt friction and wear resistance.

Fabric insert layers stiffen synchronous belt teeth to raise load capacity or reduce belt width while preserving pitch line control.

A tuned primary-to-secondary twist ratio in para-aramid plied cord balances tensile strength, bending fatigue, and belt pop-out resistance.
