Shafts TRIZ Cases
- Final Drive Shaft Fracture Containment
A final drive shaft fractures at a reduced diameter breaking portion inside the housing to contain broken ends.
- Composite Roll Bearing Retainer Design for Friction Reduction
A composite roll bearing uses retainer portions to hold radial rollers, eliminating sliding contact with the inner ring raceway.
- Ball Joint Structure With Insert-Molded Stepped Bearings
Insert-molded stepped bearings in a ball joint structure prevent resin permeation, reduce weight, and eliminate complex assembly processes.
- Multi-Component Fiber Slide Layer for Bearing Stability
Multi-component fibers bond PTFE with a polymer matrix to improve fiber-matrix adhesion and reduce breaking points in slide layers.
- Asymmetrical Cage Angular Ball Bearing for Noise Reduction
Optimizing contact angle and pocket geometry reduces slippage, preventing abnormal noise and temperature rises in grease-lubricated bearings.
- Solenoid Shunt Side Bearing Non-Magnetic Material
Non-magnetic shunt side bearings reduce radial flux transfer and lateral forces on solenoid armatures.
- Fluid Dynamic Bearing Recirculation Channel and Sealing Gap Design
Enlarged recirculation channels and tapered sealing gaps use centrifugal force to remove air bubbles, preventing accumulation that impairs bearing reliability.
- Ball Joint Housing Converts Plastic Shrinkage to Preload
A plastic one-piece housing encloses two bearing shells with a gap, converting curing shrinkage into contact pressure to resolve manufacturing precision issues.
- Fluid Dynamic Bearing Axial Clearance Manufacturing Method
Manufacturing method for fluid dynamic bearing devices sets thrust bearing clearances by forming axial clearance between bearing and sealing members.
