Roller Bearings TRIZ Cases

Labyrinth cage structure retains lubricating oil within taper roller bearings, preventing excessive outflow that causes poor lubrication and high energy loss.

A raceway element with a continuously changing curvature profile guides rollers along the contact surface.

A gearbox assembly uses a gripping means to lock the tail bearing assembly and maintain worm shaft position.

A self-aligning radial support bearing pivots on a spheroidal joint to accommodate motor shaft bending.

Hydraulic actuators drive a unidirectional clutch to rotate the bearing race, distributing static loads across different arcs to prevent localized wear.

A bearing assembly damper passage pressurizes fluid to absorb shaft vibrations while directing flow through a second passage to lubricate the seal.

Rotating the normally fixed bearing element distributes wear and prevents hydrogen embrittlement from static lubricant pressure.

A tapered roller bearing cage features a recessed portion in its small-diameter annular region to reduce local rigidity.

Pressure-driven oil supply routes lubricant through stator ducts to rolling elements, bypassing centrifugal force limitations.

Merging bearing and gear functions into one unit eliminates unfavorable tolerance chain accumulation while maintaining radial preload for high load capacity.

Segmented sheet steel components joined by laser welding reduce the weight of large bearing sealing systems while enabling easy disassembly for maintenance.

A two-stage cross roller bearing supports a flexible gear and input shaft, reducing component count while maintaining moment load capacity.

Split retainer segments employ roller stopper parts to restrict segment movement, preventing noise and damage while maintaining lubrication performance.

Piezoelectric sensors detect axial displacement of bearing units, alerting operators when thresholds are exceeded to prevent spindle misalignment.

Asymmetric cage clearance directs lubricant inflow while restricting outflow, reducing temperature rise and extending bearing life under limited supply.

Projecting cage bars create an oil curtain that blocks abrasive contaminants from entering the rolling surfaces.

A PTFE slide layer on bearing flanges minimizes friction and wear from axial loads, extending service life while maintaining structural integrity.

Intermediary guards and retainer caps preserve bearing alignment stability, preventing misalignment damage during shipping.

An interrupted conductor track bridges signal gaps within a single flexible line, reducing carrier space requirements for electronic modules.

Snap-fitted radial protrusions control grease flow on stationary rings, preventing uncontrolled migration and reducing friction losses.

Radial axial bearing integration maintains full hub length, distributing forces over a wider base to reduce tilting and enhance structural integrity.
