Rolling Contact Bearings TRIZ Cases

A single grinding wheel machines both the raceway and ring mounting surfaces, reducing device size and cost.

Electrically insulating sleeves isolate the bearing cavity from mounting arms, preventing shaft currents and enabling cost-effective metal roller bearings.

A bearing ring form-coupling arrangement interlocks a steel core with a lightweight outer body to prevent relative displacement under thermal expansion.

Forward-backward extrusion exposes high-purity metal at raceways, resolving rolling fatigue life issues.

Axial and radial dampers absorb axis and radial vibrations from the rotating ball nut, reducing noise transfer to the driver.

A clutch bearing uses a labyrinth path to block pollution entry without relying on sealing lips.

A low thermal conductivity spacer sits between the turbine wheel and inner race to block heat flow into the rolling element bearing assembly.

A manufacturing process embeds electronic sensors within a roller core using conductive film routing and elastomeric coating to protect components.

External outboard bearings reduce shaft deflection in small diameter pulleys, preventing failures while maintaining article orientation.

Merges torque motors, friction brakes, and measurement scales into eccentric rings to eliminate external adjustment mechanisms.

MnS-covered oxide inclusions prevent hydrogen accumulation, stopping premature separation from embrittlement in high-speed rolling bearings.

Separate tapered roller rings with a sleeve-based adjustment device simplify rotor shaft bearing assembly by reducing alignment time and damage risk.

A vacuum pump back-up bearing assembly equipped with a sensor to detect rotor contact events.

Recessed portions on iron core holders accommodate jigs that fix the rotor, preventing axial center displacement during bearing replacement.

A light alloy hub bearing uses a plastically deformed rolled edge to generate axial preload on the inner rings.

Through-bore flow channels enable dynamic lubricant circulation that prevents film tearing and removes air inclusions during high-frequency joint movements.

Protective gas and a coolant jacket reduce temperature stress on centrifuge bearings during high-speed operation.

A wheel bearing uses a guide portion to align projection portions for precise press-fitting of the hub wheel and outer joint member.

L-shaped outer lip seals knuckle gap to prevent muddy water entry and corrosion.

Segmented plate springs enable precise pre-load control in three-dimensional survey devices without complex washer stacks.

A common flange element prevents axial displacement of rolling-element bearings through thermal shrink fitting, reducing manufacturing complexity.

Independent temperature regulation of bearing rings maintains constant preload, preventing friction-induced overheating and ensuring guidance accuracy.

Inclined elastomeric lips and frustoconical shields create dual labyrinth seals, preventing water ingress while lowering friction and weight.

Notched pillar sections in a vehicle wheel bearing cage allow elastic deformation for easier ball installation while increasing retention capacity.

Face splines on the hub and bearing synchronize rotation with the drive shaft, preventing slip during rapid acceleration.

Relocating the oil-repellent film to the shaft simplifies manufacturing while suppressing base oil contamination in hard disk drive pivot assemblies.

A slinger with an axial cylindrical wall forms a labyrinth to block rainwater and dust while preserving seal lip design freedom.

Segmented stator oil rooms with a closing mechanism resolve tilted-position lubrication reliability issues.

A compound curve with multiple radii distributes stress across the hub wheel shoulder, preventing interference and improving mechanical strength.
