Casimir rack and pinion as a miniaturized kinetic energy harvester
Physical Review E, 2016We study a nanoscale machine composed of a rack and a pinion with no contact, but intermeshed via the lateral Casimir force. We adopt a simple model for the random velocity of the rack subject to external random forces, namely, a dichotomous noise with zero mean value. We show that the pinion, even when it experiences random thermal torque, can do work

Plasmonic rack-and-pinion gear with chiral metasurface
SPIE Proceedings, 2016The effect of circularly polarized beaming excited by traveling surface plasmons, via chiral metasurface is experimentally studied. Here we show that the propagation direction of the plasmonic wave, evanescently excited on the thin gold film affects the handedness of the scattered beam polarization.

Noncontact Casimir rack and pinion as an excitable system
Applied Physics Letters, 2015We study the influence of thermal noise on the rack and pinion coupled by the lateral Casimir force. The pinion position versus time exhibits a sequence of spikes. We identify the Casimir machine as an excitable system equivalent to the Adler system. We show that the interspike time distribution can be analyzed to access the Casimir and friction forces.

The invention relates to a rack-and-pinion steering (1), particularly for a motor vehicle, comprising a steering-gear housing (2) and a pinion (3) that is mounted inside the steering-gear housing (2). A rack (4), which engages with the pinion (3) via a toothing (5), is mounted inside the steering-gear housing (2) in an axially displaceable manner.

Optimal Design of Rack-and-Pinion Steering Linkages
Journal of Mechanisms, Transmissions, and Automation in Design, 1983A mathematical model is developed for the design synthesis of rack-and-pinion steering linkages. The general objective is to minimize the difference between the steering centers over the full range of steering angle inputs while fitting into a reasonable space.

New Rack and Pinion Steering Design and Manufacturing Technology
SAE Technical Paper Series, 1984<div class="htmlview paragraph">The justification for variable-ratio rack and pinion steering is discussed in the context of the modern front-wheel-drive car. The rack tooth geometry associated with this new steering technology prompted the development of a rack forging process which enables the forming of the entire rack cross-section in a ...

Experimental Investigation on a Rack and Pinion Inerter with Amplified Inertance
This study explores a novel vibration control device which consists of an improved inerter with enhanced inertance, conceived to boost structural performance during dynamic events. By embedding a traditional inerter within a rhombus truss structure, the device leverages a geometrical amplification effect, based on the diagonal ratio of the truss, to ...Masnata C., Di Nardo L.

RACK-AND-PINION STEERING SYSTEM FOR MOTOR VEHICLES
2003The invention relates to a rack-and-pinion steering system (1) for motor vehicles. Said steering system comprises a steering rack (12) which is mounted in a housing (8) in such a way that it can be displaced in a longitudinal manner and is continuously engaged with a pinion (9) by means of a pressure piece (13).
