Needle Bearings TRIZ Cases
- Skateboard Motor Bell Assembly for Cooling and Easy Wheel Removal
Open motor bell airflow and revised bearing layout cut friction and heat while enabling one-step wheel and motor bell removal.
- Axle Wheel End Axial Thrust Assembly Design
Integrated wheel end bearing assembly handles axial thrust loads through needle rollers and thrust washers.
- Needle Bearing Cage With Elastic Deformation Portions
A needle bearing cage uses circumferential elastic deformation portions to enable shrinkable installation within a drawn cup outer ring.
- Polygonal Bearing Radial Clearance Elimination
Polygonal bearing design with elastic raceway sections eliminates radial clearance, reducing noise and uneven loading in vehicle transmissions.
- Planetary Gear Spider Shaft Mounting with Thrust Washer
Thrust washer design reduces installation space and device complexity while ensuring precise mounting and effective sealing across tolerance positions.
- Bearing Pin Upset Method for Tappet Retention
Concave peen tools displace axle material into bulbous ends, locking the bearing while preventing axial deformation and tilting.
