Eccentric-Shafts TRIZ Cases

Integrated fan blades drive fluid through eccentric shaft inlets and outlets to lubricate and cool bearings at higher compactor speeds.

Pressure-generation regions create a fluid film during eccentric rotation, cutting thrust-surface friction while maintaining leakage control.

Pulling means clamp conical polygonal hubs onto a shaft to resist dynamic torque, avoid locking rings, and preserve shaft strength.

A non-circular crank hole lowers press-in force in turbocharger pin assemblies while preserving a strong interference fit under tolerance variation.

Side-port fluid supply in an ESP journal bearing stabilizes pressure zones, boosting load capacity and reducing vibration and wear.

A non-circular crank hole lowers pin press-fit force while preserving connection strength despite opposing tolerance deviations.

A counterweighted unloader shifts the driveshaft between compliant and constrained states to limit deflection, friction, noise, and leakage.

Elastic coupling sections absorb shaft alignment and length tolerances to prevent jamming while preserving precise, backlash-free torque transmission.

Circumferential high- and low-pressure grooves create a fluid film that cuts eccentric sliding friction while limiting scroll compressor leakage.

A variable-width bearing journal and multi-row needles carry unbalance loads in the load zone while reducing edge wear, friction, and axial thrust.

An eccentric pin, threaded annular element, and anti-rotation lock enable in-place aircraft slat roller gap adjustment without disassembly.
