Crankshafts TRIZ Cases

Meshing flywheel teeth decouple the crankshaft from the rotor, enabling high-speed torque transmission without exceeding bearing surface speed limits.

Segmented crank shaft modules allow radial repositioning of coupling elements, resolving the trade-off between precise adjustment and development adaptability.

Moveable support system holds gas turbine gearboxes via pipe connections to allow independent section movement.

Porous coating films reserve excess bleeding lubricant to prevent separation at high temperatures while maintaining low friction resistance.

Segmented hollow crankshaft journals lower weight and material waste while maintaining structural integrity under load.

Angularly offset counterweights balance crankshaft forces, simplifying manufacturing and lowering costs.

Segmented preforming steps distribute billet volume to reduce counterweight deficiencies and minimize flash formation in forged crankshafts.

Throttling elements regulate lubricant flow through the bearing gap to maintain consistent pressure.

Precise alloy control reduces residual stress and prevents cracks during induction hardening, eliminating the need for tempering.

Multi-axis probes measure diameters on stationary workpieces, eliminating eccentricity errors from headstock positioning inaccuracies.

Asymmetric crank arm recesses resolve the contradiction between reducing crankshaft weight and maintaining structural rigidity.

Receding areas on main journals relieve edge pressures from misalignment, enabling uniform plain bearing shells and reducing spare parts logistics complexity.
