Chain Links TRIZ Cases

Hardened carbide or nitride layers on chain pins and bushings cut wear, limit elongation, retain oil, and reduce vibration and noise.

Curved, recessed stainless-steel chain link geometry reduces debris buildup and equipment contact in conveyors and treatment systems.

Elastic bistable scissor linkages let a band snap open or closed with one hand, avoiding complex clasps while improving durability.

Permanent magnets create stable open and closed band states, enabling secure one-handed wearable attachment without complex clasps.

Rounded end faces on a chain link plate cut guide surface pressure and wear even under slight tilt, while keeping production practical.

Atmospheric-pressure CVD coats steel parts uniformly, including bores, while limiting anti-caking agent embedding in wear-resistant layers.

A link plate marker shows allowable chain elongation directly on the chain, enabling fast wear checks without special gauges.

Hardened carbide or nitride layers on chain pins and bushings cut wear, retard elongation, and reduce vibration under contaminated lubrication.

CVD hard coating with controlled Al2O3 release-agent particles prevents sintering in bulk metal parts without damaging layer homogeneity.

A polyurethane plug lets a flex rake chain link bend in two directions under load while preserving structural support in water stream cleaning.

A flat center with converging end surfaces lowers chain friction and surface pressure while preserving tensile strength in a compact link plate.

Inclined regions and an end-segment extension guide sprocket teeth smoothly into chain spaces, reducing noise and stabilizing shifting.

Axial stops in chain link recesses keep tensile loads inside the link, preventing chain pin wear and enabling lubrication-free high-temperature operation.

Pivoted legs and levers let a people conveyor use shorter chain links, cutting sprocket diameter and vertical installation space.

Non-uniform bush thickness prevents deformation during press-fitting, reducing wear in intra-engine chains.

Embedding abrasive particles in bush chain pin holes grinds coupling pins to distribute load uniformly, suppressing stretching and adhesive wear.

Asymmetric axial protuberance enhances sprocket grip while reducing interference and noise during shifting.

A chain plate features an inner surface with first and second inclined regions to guide sprocket teeth into engaging spaces.

A chain link marking indicates elongation through visual visibility.

Segmented locking means and elastic return units allow tool-free adjustment of bracelet length while maintaining a compact, aesthetically pleasing profile.
