Bearing Assembly TRIZ Cases
- Fluid Dynamic-Pressure Bearing with Annular Oil Buffer
Widened annular gap acts as an oil buffer to prevent leakage and reduce shaft loss in compact fluid dynamic-pressure bearings.
- Miniature Gearbox Output Shaft Axial Positioning via Segmented Design
Segmented output shaft uses a larger-diameter positioning part to limit axial displacement under alternating loads, extending service life.
- Flanged Bearing Shell with Composite Material Segmentation
Segmenting the substrate from the softer coating reduces material consumption while maintaining dimensional stability.
- Ring-rolling bearing with adjustable axial amplitude
A segmented ring rolling bearing uses undulating surfaces to convert rotation into reciprocating axial motion.
- Fluid-Actuated Rotary Drive Compact Fastening
Inverted fastening screws secure a narrow bearing ring, reducing overall device width while maintaining structural rigidity.
- Jet Propulsion Rotor Cathodic Protection via Conductive Bearings
Conductive bearing elements electrically connect the rotor to the housing for reliable corrosion protection.
- Vehicle Hood Unlocking Device with Segmented Carrier Element
Segmented carrier components isolate axial and transverse forces to eliminate excessive play in the vehicle hood unlocking mechanism.
- Electric Motor Lid Retention Without Resin Curing
Mechanical retaining element replaces thermal resin curing to secure electric motor lid and prevent rotor leaks.
- Securing Screw with Latching Levers for Play-Free Steering Gear Fixation
Latching levers on the securing screw expand radially to lock into housing teeth, preventing play caused by thermal expansion differences in steering gears.
- Flange Bearing Shell Axial Radial Assembly Caulking
Caulking retaining tongues into undercut recesses secures axial bearing parts to radial shells, preventing stress buildup and maintaining dimensional accuracy.
- Crankshaft Flywheel Assembly One-Piece Guide Ring Shear Reduction
One-piece guide ring aligns axial bores with crankshaft and flywheel, reducing shear forces on fixing screws during cold start-up.
- Sculptured Bearing Liner Weight Reduction
Variable thickness in a sculptured bearing liner reduces weight by up to 40% without compromising structural integrity.
- Integrated Air Foil Thrust Bearing Merging Top and Bump Foils
Merging top foils with bump foils reduces component count and welding steps while expanding the load support area for improved stability.
- Roller Apparatus Grounding Member Design
Segmented elastic grounding member increases contact area and force, preventing static electricity damage while maintaining component alignment.
- Ball Sleeve Joint Angular Positioning for Sensor Alignment
Asymmetric rotation-preventing means fix the ball sleeve angular position, ensuring signal emitter alignment within the magnetic sensor detection range.
- Rotatable Object Tracking Device with Balanced Clamping
Balanced tracking devices clamp to rotatable components, storing usage history to prevent failures from missed maintenance intervals.
