QUE SIGNIFIE ROLAMITE EN ANGLAIS
Rolamite
Rolamite est une technologie pour les roulements à friction très bas développés par Sandia National Laboratories dans les années 1960. Inventé par l'ingénieur de Sandia Donald F. Wilkes et breveté par lui le 24 juin 1969, ces appareils utilisent une bande de métal et des rouleaux de rotation contraints dans une enceinte pour créer un dispositif de roulement linéaire qui perd très peu d'énergie pour le frottement. Une source prétend que c'est la seule invention mécanique de base du 20ème siècle. Les tests effectués par Sandia indiquaient que les mécanismes de Rolamite ont montré des coefficients de friction aussi bas que 0,0005, un ordre de grandeur supérieur aux roulements à billes à l'époque.
définition de rolamite dans le dictionnaire anglais
La définition de la rolamite dans le dictionnaire est un dispositif de roulement sans frottement utilisant deux rouleaux et une bande flexible mobile.

THE AMAZING ROLAMITE (Continued from page 95) is called a force bias — the
rollers are made to "prefer" a particular point on the band. To understand the
effect of a slot in the band, think of the two loops of the S as springs that each

Rolamite Rolling-Gate Valves
With floating rollers, the rolamite valve also worked as a steam trap. Rolling-gate valves, using high-strength porous material to support the gate and quietly throttle the fluid, have many advantages.
