Driving Belts TRIZ Cases

High-aspect-ratio reinforcements in an elastomeric elevator belt jacket help prevent fatigue cracking under high deformation and low temperatures.

A dense core wrapped with a lighter thread constrains filament movement, improving crimp resistance and bending fatigue in rubber reinforcement.

Offset layered fiber-composite tension elements reduce sheave bending stress while keeping elevator belts strong, durable, and compact.

Movable guide flanges let elevator belts shift without rigid flange contact, reducing climbing, tension, and wear under fleet angles.

Two meshed belts separate positioning and drive functions to stiffen a sliding base and keep long-stroke tool changing accurate.

A full-width support member couples passenger conveyor belts without through-holes, enabling narrower belts and more secure joints.

A Lang-twisted carbon fiber cord and tuned rubber hardness improve toothed belt flexibility, tooth crack resistance, and high-load durability.

A reinforced coating with fibers or hard particles helps endless belts resist cracking, tearing, and detachment under continuous load.

Side-contact nubs let one belt engage circumferentially grooved pulleys for stronger torque transfer with lower oscillations.

Arcuate rib flanks and a Shore A 85-100 polymer surface keep elevator rope friction stable over time, reducing twist, sway, and traction drift.

A higher-modulus outer strand layer delays inner strand breakage, preventing sudden cord fracture and enabling predictive maintenance.

By tuning unloaded and loaded belt pitch against pulley pitch, this case reduces steering belt noise and vibration without losing grip.

A polyamide cord core and joined reinforcement fabric stabilize twist-travel belt tension, reduce joint breakage, and prevent one-sided elongation.

A reinforced toothed belt uses thicker teeth, a thicker back, and high-strength core wires to raise load capacity without increasing belt width.

A reinforced thermoplastic elastomer belt uses core wires and large tooth geometry to raise load capacity without increasing belt width.

Controlled hot rolling, cold rolling, and aging raise steel belt strength while stabilizing crack propagation resistance without patenting.

A thermoplastic bonding film replaces RFL in power transmission belts, preserving layer adhesion and belt life while minimizing formaldehyde.

Inclined nub side surfaces help one belt mesh with circumferentially grooved and cylindrical pulleys, reducing torque oscillations.

PPS reinforcing fabric replaces nylon-66 in toothed belts to improve heat, fluid, and wear resistance while maintaining elastomer adhesion.

Aligned reinforcement in a composite belt lowers bending stiffness while preserving friction, torque transfer, and durability.

A Lang-twisted glass fiber cord and plasticized rubber help toothed belts resist water infiltration, hardening, and bending fatigue.

Aligned reinforcement fibers and layered rubber let this power transmission belt cut bending loss while preserving friction, durability, and torque transfer.
