Shafts TRIZ Cases
- Camshaft Bearing Oil Groove for Timing Chain Lubrication
A camshaft bearing integrates an oil projection groove to direct a compact lubricating jet toward the timing chain.
- Rolling Bearing Cage Inclined Surfaces for Oil Distribution
Inclined cage surfaces guide lubricating oil to critical contact areas, reducing agitation resistance and preventing seizure in high-speed bearings.
- Shaft Spray Edge for Centrifugal Gear Oil Separation
Centrifugal spray edges guide penetrating gear oil into collection pockets, preventing contamination of grease-lubricated electric machines.
- Multi-Arc Bearing Oil Supply Groove for Turbocharger Lubrication
A multi-arc bearing uses an oil supply groove with varying clearance to control lubricating oil flow between the shaft and bearing surface.
- Metal Rolling Bearing Cage Design for High-Speed Stability
Segmented metal cages resist conical deformation at high speeds, preventing outer race contact while minimizing friction through antifriction coatings.
- Torque Converter Bushing Piloting Turbine Bearing Alignment
A turbine shell bushing pilots the inner surface of a thrust bearing, resolving misalignment and instability between the turbine and stator.
- Photocurable Resin Self-Lubricating Liner Low-Temperature Wear
Zirconium phosphate tungstate in the photocurable resin reduces wear loss to one-tenth of conventional levels at low temperatures.
- Pb-Free Copper Alloy Sliding Material with Ag-Bi Eutectic
An Ag-Bi eutectic in Pb-free copper alloys resolves high friction coefficients at elevated temperatures while maintaining necessary conformability.
- Polyamide Sliding Bearing for High-Temperature Structural Applications
Cross-linked polyamide replaces PTFE in sliding bearings, maintaining compressive strength at 170°C to prevent cold flow failures in seismic structures.
- Crankshaft Damper With Intermeshed Teeth And Damping Pads
Intermeshed teeth and grooves constrain axial movement while damping pads allow circumferential rotation to dissipate vibration energy.
- Melt-Processible Fluororesin with Aromatic Polyamide Fibers
Wholly aromatic polyamide fibers entangled in a melt-processible fluororesin matrix resolve the contradiction between moldability and wear resistance.
- Foil Segment Bearing Adjustable Gap Geometry
Spring-loaded adjustment mechanism positions bearing segments radially, compensating for manufacturing tolerances to prevent shaft failure.
- Light Hollowed Spherical Plain Bearing With Internal Cavities
Internal cavities in the bearing rings act as lubricant reservoirs, extending service life without requiring expensive lightweight materials.
- Vacuum Pump Recess Port Oil Supply Mechanism
A vacuum pump recess portion guides lubricant oil above the supply port for bearing members.
