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.

Strategic oil-hole placement and local recesses improve oil film uniformity, cut friction, and prevent abnormal wear in rotary compressors.

A replaceable carrier bolt avoids replacing the full speed reducer carrier when threads are damaged, cutting repair time and cost.

A nonlinear bore hole retains a conveyor roller on its shaft to stop axial migration, misalignment, and returnway noise.

Fan-driven fluid circulation through shaft inlets and outlets cools and lubricates compactor eccentric bearings, supporting higher rotational speed.

Nitrogen springs and an eccentric camshaft let this rail brake clamp hard with low particle generation and no external utilities.

A base-and-head seal geometry deflects water and debris away from floor machine bearings, reducing wear and extending bearing life.

A single-piece offset shaft with multiple bends simplifies automatic toothbrush assembly, cuts operating noise, and improves tool power transfer.

Offset slots in a nonlinear roller bore hold the roller on the shaft, preventing axial drift, belt misalignment, and noise.

Non-circular cross sections replace expensive frictional grips to simplify assembly while maintaining precise angular positioning of eccentrics.

An eccentric shaft design positions bearing seats at a concave angle to counteract centrifugal bending, reducing thermal stress and extending bearing lifespan.

A piston pin integrates plunger spaces and check valves to adjust compression ratios via hydraulic pressure.
