Casimir Rack and Pinion
As the technological advances lead to miniaturization of mechanical devices, engineers face new challenges that are brought about by the fundamentally different rules that apply at small scales. One of the biggest problems in small machines is the excessive wear of the many surfaces that work in contact with each other, which severely constrains the durability of such machine parts. Here, a for...
متن کاملNoncontact racK and pinion powered by the lateral Casimir force.
The lateral Casimir force is employed to propose a design for a potentially wear-proof rack and pinion with no contact, which can be miniaturized to the nanoscale. The robustness of the design is studied by exploring the relation between the pinion velocity and the rack velocity in the different domains of the parameter space. The effects of friction and added external load are also examined. I...
متن کاملRectification of the lateral Casimir force in a vibrating noncontact rack and pinion.
The nonlinear dynamics of a cylindrical pinion that is kept at a distance from a vibrating rack is studied, and it is shown that the lateral Casimir force between the two corrugated surfaces can be rectified. The effects of friction and external load are taken into account, and it is shown that the pinion can do work against loads of up to a critical value, which is set by the amplitude of the ...
متن کاملSensor-Actuator Based Smart Yoke for a Rack and Pinion Steering System
The controlling behaviour of a vehicle is influenced by the performance of its steering system. The steering system consists of steering wheel, steering column, rack and pinion, steering gearbox, and a linkage system. The vehicle is controlled by the behaviour of the steering gear with the spring loaded rack and pinion. This spring loading arrangement consists of yoke nut, spring, and plunger. ...
