Connecting Rod Bearings TRIZ Cases

Non-circular wrist pin design maintains lubrication film while reducing contact pressure to minimize wear and noise in internal combustion engines.

Reshaping bearing coatings before fracture separation maintains precise fit in connecting rods.

Freezing and snapping the workpiece along a curved path increases engagement area to prevent fatigue failure.

Segmented oil groove design directs lubricating flow through specific bearing zones to maintain stable pressure and reduce leakage.

A drawn cup needle roller bearing outer ring achieves precise track surface geometry to ensure stable roller guidance.

Angled slots and tangs create a precision hard stop, resolving rough fracture-split surfaces that fail to prevent rotation.

Truncated arcuate outer surface allows short-shanked clevis engagement without machining stress concentrations.

A connecting rod closing system uses wedges to lock the cap and form a uniform force path.

Zinc sulfide and barium sulfate fillers in a resin binder increase peak load capacity, preventing rapid destruction of crankshaft bearings under high stress.
