4-Point Convex-Contact Roller Bearing for Compact Planetary Drive Train - COMBINED WITH INV-13069

技术优势

Value PropositionThe roller bearing: Is highly compact Is point contact based, allowing an efficient combined load bearing function as opposed toline contact based rollers Is capable of withstanding high over-tuning thrust Is equally capable of distributing the moment loads efficiently Is associated with a reduced roller-diameter tolerance requirement Allows for a reduced slippage friction as compared to conventional techniques Enables a better gear operation as compared to conventional techniques Improves the overall structural rigidity while maintaining the gear set alignment effectively Significantly eliminates the need for external planet carrier and/or individual bearings,enabling cost and complexity reduction Would be commercially useful for the following applications:o Gear bearing driveso Other planetary gearboxes, actuators and orbiting rotating gear components

*Abstract

In prior art, use of standard parallel rollers for gear bearing drives is well-known;however, such rollers and associated bearings/drives experience one or more of thefollowing limitations, such as shear forces on gear teeth, excessive thrust, unevendistribution of moment loads, structural complexities (such as related cost, weight,volume), and significant slippage friction. This invention relates to the developmentand use of a novel 4-point roller bearing for enabling a compact, planetary drive train,overcoming the prior art limitations and/or unmet needs.
