Rotary Bearings TRIZ Cases

A circulating pump shaft element connects the impeller to the rotor while allowing rotation relative to the bearing member.

A rotor blade bearing unit uses axially offset cylindrical rolling bodies to absorb overturning moments and radial loads within a single integrated assembly.

Integrating sieves into the changeover valve protects sensitive components from dirt particles, improving reliability without increasing structural complexity.

Split inner ring track roller bearings accommodate mounting pin deflection to maintain reliability in compact wing actuation systems.

A variable length connecting rod uses a hydraulic piston mechanism to adjust effective length and mechanical compression ratio.

Thermosetting resin composition with isocyanuric acid ring forms self-lubricating liner, enabling precise grinding without compromising wear resistance.

A torsion spring applies circumferential preload to an eccentric mounted on a bearing, enabling automatic angular adjustment of the gear assembly.

Matched curvature radii on the roller eliminate differential sliding between central and end portions, extending guide surface lifespan.

Intersecting lubrication grooves in the outer race enhance fluid distribution across the sliding contact interface.

Integrally formed eccentric lever enables dynamic compression ratio adjustment, resolving engine knocking while improving fuel efficiency.

A brake piston with a prestressing spring absorbs settling momentum in an eccentric member of a connecting rod adjusting arrangement.
