Rotary Bearings TRIZ Cases
- Spherical Journal Bearing for Low-Speed High-Load Wind Drivetrains
A hydrodynamic spherical bearing spreads wind drivetrain loads through a fluid film, cutting wear, handling misalignment, and simplifying support.
- Aircraft Joint With Spherical Bearing for Close-Coupled Engine Mounting
A spherical bearing and sliding pin joint lets pylons stay close to the wing while accommodating rotation and axial movement in flight.
- Eccentric Connecting Rod Bearing Assembly for Ram Range Adjustment
An offset bearing assembly lets bodymaker ram range be adjusted without removing the coupling shaft, cutting downtime and part damage.
- Bearing Cage Punching Sequence to Eliminate Chip Formation
Opposite-direction punching forms bearing cage snap surfaces and pockets without chipping, reducing tool wear and preserving accuracy.
- Conical Shoulder Mount Pin Assembly for Misalignment Relief
A conical shoulder and chamfered hole let this self-locking mount pin align under tolerance and thermal growth while shifting load away from thread shear.
- EPS Worm Reducer Bearing Support for Low-Torque Quiet Assembly
Housing-supported bearings with a damper and support member keep worm-shaft torque consistent while reducing friction noise in EPS reducers.
- Relief-Zone Bushing Geometry for Edge Load Wear Reduction
Edge relief zones enlarge the bushing ends to shift load inward, reducing lug stress concentration and wear in pinned assemblies.
- Butterfly Valve Roller-Pin Mounting for Vibration Resistance
Wave-spring biased bearings and a retained roller pin stabilize a butterfly valve mount under gas turbine anti-ice vibration.
- Eccentric Bearing Coupling for Low-Friction Actuator Fixation
An eccentric inner and outer bearing mount lets actuator couplings absorb planar and angular movement while reducing friction and force transfer.
- Gas Turbine Linkage Assembly With Anti-Rotation Biasing Member
An elastic biasing member restrains link rod rotation in gas turbine linkage assemblies, preserving needed motion while improving stability.
- Flexographic Print Deck Bearing Preload for Bounce Control
Opposed radial bearing preload and torque feed-forward stabilize flexographic mandrels, reducing print bounce and banding.
- Planetary Bearing Pin Crowning for Uniform Lubrication Under Load
A variable-bore, crowned planetary bearing pin keeps the lubricant film more uniform under centrifugal load while limiting wear and weight.
- Joint Seal Structure for Mud Pressure and Lubricant Retention
A segmented annular joint seal resists mud packing, blocks dirt ingress, and retains lubricant while staying practical to install and manufacture.
- Aircraft Structure Joint for Large-Engine Wing Clearance
A pin-and-spherical-bearing joint allows axial sliding and rotation while keeping engine and wing spacing compact for large-diameter engines.
- Elastomeric Double Hooke's Joint for Rotor 2P Vibration Reduction
A double Hooke's joint with elastomeric bearings lets the rotor hub float during flapping, cutting axial loads and 2P vibration.
- Gas Turbine Linkage Assembly With Spring Anti-Rotation Bias
A spring biasing member restrains unwanted axial rotation in gas turbine linkage bearings while preserving existing hardware and link mobility.
- Compressor Inlet Lever Bearing Assembly to Prevent Ring Tilting
A rotatable lever bearing assembly actuates the compressor inlet ring in less space while reducing tilting, damage risk, and assembly complexity.
