Rolling Contact Bearings TRIZ Cases

A vacuum-housed flywheel uses heat-sink and liquid-coolant bearing cooling to speed CMG spin-up, cut bearing stress, and reduce spin-down noise.

An integrated ring gear bearing and adjustable pre-load improve pinion support, sealing, and power transmission in axle assemblies.

An interference-fit hub bearing mount uses cantilever lugs and fewer screws to handle thermal expansion, cutting suspension weight and wear.

A noise isolating layer between the strut bearing assembly and mounting bracket cuts suspension noise reaching the vehicle body.

Embedded strain sensors at the outer-ring interface enable real-time force and moment detection while shielding the sensors from contaminants and damage.

A biasing member and sealed lubricant chambers maintain bearing preload, improve torque transmission, and reduce axle wear.

A pressure-profiled seal lip pumps oil back into the wheel hub to prevent axle leakage, reduce lubricant mixing, and extend hub life.

Movable bearings and actuators correct rotor air-gap drift from tolerances, deformation, and wear to keep magnetic-geared machines stable.

An interference-fit hub bearing with cantilever lugs cuts screw count and weight while limiting thermal-expansion noise, wear, and deformation.

Mounting the tone wheel on the wheel flange enables wheel speed sensing in tight axle-tube layouts while improving sealing and assembly.

Sensors placed between bearing race sets isolate rolling-element strain, reducing cross-talk and improving wheel hub load detection.

Combining axial negative clearance and rotational torque checks improves wheel bearing preload verification after press-fitting and swaging.

Elastomeric lips molded onto the bearing cage improve wheel hub sealing while cutting lip length, friction, and assembly cost.

A stepped upper shell lets the ball nut and inner tube pass through, simplifying suspension assembly while preserving coil spring contraction.

A shaft-based heat sink or liquid coolant removes bearing heat in a vacuum gyrostabilizer, cutting spin-up and spin-down time while preventing failure.

A radially movable hub ring and aligned swaging die cut vibration-related energy loss while preserving staking quality and axial force.

Dual-contact-angle raceways cut wheel hub bearing friction while preserving load capacity and rigidity for vehicle efficiency.

An integral outer ring, flange, and steering arm remove the hub-upright interface to cut stress, noise, corrosion, and part complexity.

A closed-loop cooling path removes motor and bearing heat inside a vacuum gyroscopic boat stabilizer, enabling faster spin-up and spin-down.

Cross-wheel sensor comparison detects wheel head malfunctions early without fixed thresholds, improving reliability under dynamic conditions.

Centrifugal sealing lips block water and dust at low wheel speeds, then detach at higher speeds to cut friction and power loss.
