Paper 3: Fluid Lubrication of Tapered Roller Bearings

, 1969
A new test rig is used to investigate the mode of lubrication of tapered roller bearings under axial loading. Two different bearing configurations for a 21/4-in shaft are used. The lubricants are mineral oils. The investigation establishes the nature of

An Analysis on Negative Effects of Shaft Deflection on Angular Misalignment of Rollers Inside Tapered Roller Bearing

Lubricants
Shaft deflection degrades roller alignment and intensifies stress concentration/edge effects at roller-ends and raceway edges, ultimately compromising service performance of tapered roller bearings (TRBs).

Stiffness‐Programmable Origami Robots With Tendon‐Driven Actuation via Multimaterial 3D Printing

Advanced Robotics Research, EarlyView.
Motion diversity is achieved in a tendon‐driven origami robot through programmable stiffness rather than modified actuation. Multimaterial 3D printing embeds soft creases, modular inserts redirect identical tendon inputs into distinct behaviors, and variable‐stiffness inserts enable real‐time switching.
