Contribution of the deflection of tapered roller bearings to the misalignment of the pinion in a pinion-rack transmission [PDF]
, 2016 The misalignment of the gears is one of the main causes of premature failure in gear transmissions. This misalignment can be caused by different phenomena where the deformation of the elastic elements of the transmission usually has a major importance ...

Development and Experimental Validation of a Bistable SMA Active Grill Shutter Actuator
Macromolecular Symposia, EarlyView.ABSTRACT This study explores the use of bistable shape memory alloy (SMA) actuators in active grille shutters (AGS) to improve vehicle aerodynamics. The actuator, designed for adaptive movement, was tested and refined to achieve a reliable 90° rotation.

Rack-and-pinion effects in molecular rolling friction [PDF]
Philosophical Magazine Letters, 2008 Rolling lubrication with spherical molecules working as 'nanobearings' has failed experimentally so far, without a full understanding of the physics involved and of the reasons why. Past model simulations and common sense have shown that molecules can only roll when they are not too closely packed to jam. The same type of model simulations now shows in

Actuation Strategies for Underwater Jet‐Propelled Soft Robots
Journal of Field Robotics, EarlyView.ABSTRACT This review article examines jet‐propulsion mechanisms in underwater soft robotic systems, focusing exclusively on physically fabricated and experimentally validated robots. Covering research published from 2013 to 2025, this study classifies and evaluates jet‐propulsion robots based on their actuation mechanisms.

Synchronizing noncontact rack-and-pinion devices
Applied Physics Letters, 2012 The lateral Casimir force is employed to propose a nanoscale mechanical device composed of one rack and N pinions. A coupling between the pinions via torsional springs is shown to coordinate their motion through a synchronization transition. The system can work against loads that are greater than the lateral Casimir force for each device. The existence

Opportunities for the Labour Party: Football, Class and Community Renewal
The Political Quarterly, Volume 97, Issue 2, Page 323-333, April/June 2026.Abstract This article argues that football represents an underutilised opportunity for the Labour Party to anchor a wider programme of civic renewal. In many working‐class communities, the decline of trade unions, working men's clubs and other associational spaces has eroded collective life, leaving football clubs as rare institutions where dignity ...

Tooth contact analysis of a non-involute rack and pinion system for off-shore application
, 2022 A jack-up is an off-shore platform that, thanks to the capability of lowering its legs, is capable to elevate its hull from the water. Typically, the movement of the leg and the subsequent emersion of the jack-up is ruled by a rack-pinion system in which
