Drip Or Splash Lubrication TRIZ Cases

An undercut groove and deflector guide oil to distant components at lower rotational speed, reducing scatter and power loss.

An undercut groove and upper deflector help a rotating lubricant distributor reach distant transmission parts at lower speed with less oil scatter.

Integrated oil slinger on clutch locking plate maintains lubrication during air turbine starter operation despite declining oil levels.

Ring gear collects lubricant from a sump and transfers it to pinion teeth via a scraper and second sump, eliminating costly rotary fluid pumps.

A modular oil treatment system integrates a passive pump and filter into dipstick tubes to circulate and purify engine lubricant.

Gravity-fed deflectors route oil to spline interfaces, preventing fretting and corrosion in agricultural harvesters.

A gearbox lubrication system uses a gravity-fed container to capture and redirect splashed oil, reducing splash losses during low torque operation.

Open cell metal foam encircles rotating structures to direct lubricant flow, preventing churn and overheating caused by windage.

A lubricating jig assembly uses a pump and nozzle system to apply fluid directly onto vehicle panel edges during installation.

A transmission lubricant supplying structure directs fluid against a shifting fork side surface to channel oil toward an embedded clutch gear.

A trochoid pump driven by the camshaft splashes oil mist into the cylinder bore and valve chamber of a lightweight four-cycle engine.

A link type variable stroke engine positions an oil supply hole on a sub connecting rod tubular part to guide lubricant via splash action.

Low surface tension and viscosity formulations minimize churning power loss while maintaining adequate film strength.

A lubricating device circulates gear oil through a filter unit to remove contaminants from wind power station gear trains.

Dispersant olefin copolymers stabilize silicone oil in hydrocarbon base oils, resolving phase separation issues while reducing surface tension and friction.

Asymmetric piston geometry and multi-stage telescoping poppet valves reduce engine weight while increasing overhead space for valve placement.

A differential deflector redirects the lubricant stream generated by a rotating ring gear to disperse fluid across internal components.

A polymer sealing baffle with a compressing lip protects transmission torque transfer components from lubricant flooding.

A timing belt pulley mounts to a crankshaft pin assembly via a slot-and-key interface.
