Noncontact rack-pinion-rack device as a differential vibration sensor
Physical Review E, 2010We study a nanoscale system composed of one corrugated cylinder (pinion) placed between two corrugated plates (racks). The pinion and racks have no mechanical contact, but are coupled via the lateral Casimir force-one of the most spectacular consequences of quantum fluctuations of the electromagnetic field.

Effect of Pinion Profile Modification on Rack and Pinion Steering Gear
SAE Technical Paper Series, 2005<div class="htmlview paragraph">Low rack gain and high reduction gear ratio in the case of Rack and Pinion Steering (RPS) gear of an automobile puts a limit on pinion diameter. The tooth strength for small diameter pinion is achieved by reducing the number of teeth. Undercutting is avoided by resorting to a pinion profile shift. The profile shift

Electronics and Power, 1970
The field over an open-sided linear motor contains a rotating component which can be used to spin rotors In a manner that is analogous to a rack-and-pinion action. If the rotor is made up of a stack of washers—a divided-cylinder rotor—some Interesting effects can be obtained.

A Rack-and-Pinion Pumping Unit Design
Advanced Materials Research, 2012This paper presents a rack-and-pinion pumping unit. A type of SRD (switched reluctance driver) motor is utilized as the driving unit of the pumping unit. The rotation direction of the output shaft of the motor can change automatically, without reversing mechanism，so it can directly dive the gear box and then drive the rack-and-pinion in which the rack ...

Effect of thermal noise on noncontact rack and pinion device
Physical Review E, 2012We study a nanoscale system composed of one corrugated plate (rack) and one corrugated cylinder (pinion) coupled via the lateral Casimir force. We assume that the rack moves uniformly. The axle of the pinion experiences frictional torque and random torque due to a surrounding fluid.

Improvements in Rack and Pinion Steering Gears
SAE Technical Paper Series, 1983<div class="htmlview paragraph">The most effective way to improve the driver's road feel at high speeds is to increase the stiffness between the steering wheel and the vehicle's wheels at times when only a small amount of steering effort is required.</div> <div class="htmlview paragraph">Though rack and pinion steering systems have ...

Dynamics of noncontact rack-and-pinion device: Periodic back-and-forth motion of the rack
Physical Review E, 2010We study a nanoscale system composed of one corrugated cylinder (pinion) and one corrugated plate (rack). The pinion and rack have no mechanical contact, but are coupled via the lateral Casimir force. We consider the case where the rack position versus time is a periodic triangular signal.

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

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.

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.
