Shafts TRIZ Cases
- Oil Conveyor Ring Lubrication for Electric Motor Bearings
A rotating oil conveyor ring pumps lubricant from a sump to electric motor bearings, eliminating frequent relubrication needs.
- Self-lubricating Composite Hinge Assembly for High Dynamic Loads
Crossed fabric layers in a resin matrix provide load resistance above 40 MPa, preventing seizing and delamination under high dynamic loads.
- Hollow Shaft Recess for Sealing Member Fixation
An inner peripheral recess in the hollow shaft secures the sealing member against assembly stress, preventing dirt intrusion into bearing portions.
- Grooved Thrust Bearing for High-Speed Gas Spindle Stability
Directional grooves in the thrust plate stabilize high-speed rotation, increasing disk-loading capacity without sacrificing precision.
- Countershaft Bearing With Axial Variations For Load Adaptation
A countershaft bearing with axial variations adjusts its profile dynamically to resolve instability under varying load conditions.
- Al-base Sliding Bearing Fatigue Resistance via Hypercomplex Intermetallic Compounds
A sliding bearing uses hypercomplex intermetallic compounds to strengthen the aluminum alloy matrix and resist plastic deformation under high specific loads.
- Tapered Elastomeric Bearing Shear Stress Reduction
Tapered elastomeric layers reduce edge bulging by distributing radial and axial loads, extending bearing lifespan under heavy mechanical stress.
- Strut Bearing Flange Design for Machining Accuracy
Radial flange portions hold raceway rings within synthetic resin cases, eliminating axial height increases that deteriorate machining accuracy.
- Carbon Nanotube Sliding Bearings for Friction and Wear
Oriented multi-walled carbon nanotubes in PEEK or PPA sliding layers resolve the trade-off between high wear resistance and low coefficient of friction.
- Brush Damper Rings for Radial Gas Bearing Damping
Interlocking brush damper rings generate friction to resolve low damping and rotordynamic instability in high-speed gas bearings.
- Axial Bearing Wedge Surface and Sealing Flanges
A turbocharger axial bearing uses a wedge surface and sealing flanges to generate hydrodynamic pressure.
- Stepped Bearing With Variable Interference Fit
A stepped bearing assembly uses variable interference fit to maintain contact pressure within a gas turbine engine housing.
- Superhard Bearing Wear-In for Hydrodynamic Lubrication
Controlled wearing-in of superhard thrust bearing elements reduces friction and heat generation under high loads by establishing a protective fluid film.
- Conical Fluid Dynamic Bearing Sealing Gap Design
An open sealing gap between the bearing cone and rotor component allows optical filling level inspection, eliminating complex leak-proof connections.
- Open-core flywheel with HTS bearings
An open-core flywheel architecture uses high-temperature superconducting bearings to support the rotor without mechanical contact.
- Motor Frame Convex-Concave Segmentation for Rotor Concentricity
Segmented frame parts with convex-concave interfaces maintain rotor concentricity despite manufacturing precision trade-offs.
- Strut Bearing Injection Molded Guide Ring Assembly
An injection molded plain bearing on the guide ring eliminates separate component assembly and reduces positioning errors in strut bearings.
- Sleeve Bearing Lubricant Reservoirs for Stress Reduction
Interrupted elongate lubricant reservoirs balance load distribution and reduce wear by eliminating sharp corner stress concentrations.
- Gear System Lubricant Reservoir in Slidable Bearing Section
A gear system bearing structure incorporates a lubricant reservoir within its slidable shaft and hole interface to maintain consistent lubrication.
- Sliding Contact Surface Material for Dry Friction Wear Resistance
A sliding contact surface-forming material uses a woven fabric with fluorine-containing resin and polyphenylene sulfide fibers impregnated with resol-type phenolic resin.
