Roller Bearings TRIZ Cases

A molded polymer ring with flanges and a central protrusion joins bearing inner rings securely while cutting retainer complexity and cost.

Annular concave mold sections redirect material flow in rolling body compression molding to limit excess material, end recesses, and post-processing.

Different roller lengths and contact angles equalize surface pressure in a double-row self-aligning bearing, boosting load capacity and life.

An elastic coupling linked to the main bearing ring compensates rotor shaft deflection and offsets while shortening the wind turbine drivetrain.

Opposed left- and right-handed threads let rollers self-compensate, carrying high loads in a compact bearing while preventing axial slippage.

Dual damper rings and linked damping chambers center a turbomachine bearing while balancing radial vibration, sealing, and fluid demand.

An endless coil spring bearing flexes into an ellipsoidal shape to reduce one-sided contact and rotational torque in strain wave gearing.

By forming the outer raceway in the bearing block, this case frees space for larger cooling channels and rolling bodies in continuous casting rolls.

A split clamping band and seal wear ring let tapered roller bearings be replaced on wind turbine shafts without disconnecting the mainshaft.

A concave outer race, rolling elements, and a lubricious liner let flap hinge bearings handle misalignment and sliding with lower friction.

A bore-mounted sensor and microgenerator enable cable-free load measurement in rolling bearings with wireless data transfer and lower maintenance.

A cage stopper guides tapered rollers over the inner ring rib with less force, reducing cage strain, whitening, and cracking during assembly.

Radial and axial squeeze film dampers absorb vibration and dissipate kinetic energy in driven turbocharger traction drives.

Centrifugal lubricant flow through radial passages feeds the planet gear bearing cage, improving lubrication reliability at high rotational speeds.

Boss-and-aperture indexing aligns the split seal wear ring on the clamping band, enabling mainshaft-free bearing replacement with sealing and preload control.

Preset bearing clearance built into a non-split angular contact roller bearing cuts mounting time, adjustment errors, and maintenance effort.

Induction quench hardening localizes high hardness to the raceway while keeping bolt-hole regions machinable and reducing bearing ring cost.

Frusto-conical bearing cages guide oil outward in turbine reduction gears, cutting recirculation, improving cooling, and reducing wear and coking.

A folded disk-shaped flange in a two-piece thrust bearing cage improves stiffness, flange uniformity, and piloting surface under tight clearance.

Parallel inlet galleries feed each squeeze film annulus evenly, reducing air entrapment and stabilizing oil film thickness in gas turbine dampers.

Blocking oleophobic spread at the separator ends keeps the tapered seal interface stable and helps prevent lubricating oil leakage under impact.

Controlled carbonitriding keeps nitrogen uniform in bearing contact surfaces, improving hardness, crack resistance, and contact life.

A soft ring-shaped transport jig presses bearing rollers to stop vibration damage in transit without clearance management or retained foreign matter.

Adjustable segmented seal parts control the bearing final gap to block wear dust and avoid seal contact from tolerance and thermal expansion.

Two nested tube-shaped retainers keep rollers contained during bearing ring removal, reducing skew, damage, and maintenance risk.

A detachable guide and coupling piece positions inspection probes at fixed angles and distances in wind turbine main mounts without contamination or collisions.

Individual anti-friction separators replace sliding cages in radial bearings to cut wear, raise speed range, and extend service life.

Dual guide facets and lubricant grooves in a single-piece self-aligning bearing cage reduce roller stress, friction, and micro-flaking.

A removable retainer adjusts raceway width so one bearing ring fits different roller sizes, cutting production complexity and material cost.

A lubricant film lets the bearing outer portion move relative to the housing, keeping a tight non-contact seal gap while reducing air leakage.

Variable-width grooves and rollers with changing effective diameter cut sliding losses, stress concentration, and transmission weight.

A captive auxiliary ring and cage lug connection lets truck wheel bearings use shorter standardized outer rings while preserving geometry flexibility.

A looped belt, cable, or roving in a composite bearing carrier transfers load between rings while cutting weight and providing current insulation.

Rolling-contact orbital rollers replace gear meshing to deliver high torque, zero backlash, low noise, and compact speed reduction.

Adjacent bearing cage pockets share parallel demolding directions, cutting slide count and cost while adding lubricant space.

A single radial bearing placed between two axial bearings limits deformation, supports tilting moments, and saves installation space.

Logarithmic end crowning with a straight roller center cuts edge pressure and skew in transmission tapered roller bearings, extending life.

A split bearing assembly uses spherical tilt and cylindrical rollers to handle planet gear misalignment while maintaining radial load support.

A cross roller and parallel roller layout cuts raceway alignment demands, reducing friction torque, cost, and bearing variation.

A separate seal wear ring lets large wind turbine tapered roller bearings keep sealing performance while cutting replacement cost and maintenance effort.

Ceramic rolling elements, outer-ring cooling channels, and squeeze-film damping cut turbomachine bearing losses while supporting higher speeds.

Axial recesses hold an annular seal between split bearing ring parts, preventing seal shift while preserving sealing and lubricant flow.

Pendulum broaching forms bearing cage side ring windows with less stress, avoiding burrs, warping, and extra deburring steps.

A logarithmic crowning profile and a 0.2 mm nitrogen-enriched layer cut tapered roller bearing torque, heat, and wear under high load.
