Record 1 2017-01-25

English

Subject field(s)
  • Engines (Motor Vehicles)
  • Kinematics
CONT

Torque is twisting or turning effort. Torque is measured in pound-feet(lb-ft). Any shaft or gear that is being turned has engine torque applied to it.

OBS

engine torque: term officially approved by the Lexicon Project Committee (New Brunswick).

French

Domaine(s)
  • Moteur (Véhicules automobiles)
  • Cinématique (Mécanique)
DEF

Valeur caractéristique du moteur que l'on mesure au banc d'essai et qui, multipliée par la vitesse de rotation, donne la valeur de la puissance du moteur (à un coefficient près).

OBS

couple moteur : terme uniformisé par le Comité du projet de lexiques (Nouveau-Brunswick).

Record 2 - external organization data 2005-11-08

English

Subject field(s)
  • Physics
  • Nuclear Fission Reactors
  • Compartment - Canadian Nuclear Safety Commission
CONT

Sagging does not usually become permanent but it takes time to recover the sag. To prevent a bent shaft due to sag or hog the shaft is rotated by a turning gear, which is a motor-driven gear-train mechanism on the turbine-generator shaft.

French

Domaine(s)
  • Physique
  • Réacteurs nucléaires de fission
  • Tiroir - Commission canadienne de sûreté nucléaire
CONT

Le fléchissement dû à la gravité n'est habituellement pas permanent, mais la période nécessaire au redressement de l'arbre est longue. Pour prévenir ces flexions vers le haut ou le bas, le vireur, un mécanisme d'entraînement de l'arbre, mu par un moteur, assure la rotation constante de la turbine.

Record 3 2003-05-29

English

Subject field(s)
  • Volumetric Pumps
  • Centrifugal Pumps
  • Helicopters (Military)
DEF

A form of constant displacement pump using a spur gear driven by the engine and turning inside an internal tooth gear having one more space than teeth on the drive gear. As the pump rotates, the volume at the inlet port increases, and that at the outlet decreases, moving fluid through the pump.

French

Record 4 2000-08-31

English

Subject field(s)
  • Cranes (Hoisting and Lifting)
  • Cranes (Construction Sites)
  • Shipbuilding
DEF

A crane with a jib which may be rotated by turning gear and adjusted in the vertical plane.

DEF

A crane consisting of a bracket frame or a vertical post from which extends a horizontal arm, carrying a traveler or trolley on wheels from which the load is suspended.

CONT

The jib crane has an arm guyed at a fixed angle to the head of a rotating mast.

OBS

Derricks and jib cranes are classified as fixed cranes.

Key term(s)
  • fixed crane

Domaine(s)
  • Grues (Levage)
  • Grues (Chantiers)
  • Constructions navales
DEF

Grue avec une flèche qui peut être orientée par un mécanisme de rotation et dont l'apiquage dans un plan vertical peut être réglé.

Record 5 1991-09-05

English

Subject field(s)
  • Aircraft Propulsion Systems
CONT

Most pitch-changing mechanisms are operated by oil pressure(hydraulically) and use some type of piston-and-cylinder arrangement. The piston may move in the cylinder, or the cylinder may move over a stationary piston. The linear motion of the piston is converted by several different types of mechanical linkage into the rotary motion necessary to change the blade angle. The mechanical connection may be through gears, the pitch-changing mechanism turning a drive gear or power gear that meshes with a gear attached to the butt of each blade.

French

Domaine(s)
  • Propulsion des aéronefs
DEF

variation de pas: Système permettant la rotation d'une pale d'hélice autour de son axe longitudinal pour modifier son pas et en conséquence, son effort de traction.

CONT

Les mécanismes de changement de calage [des hélices à vitesse constante] sont soit électriques, soit hydrauliques, mais dans tous les cas on trouve: - un élément sensible détectant le nombre de tours, - un élément de réglage relié à la commande, - un élément actif qui, compte tenu des deux éléments précédents, commande le changement de calage. Ces trois éléments forment le régulateur [d'hélice] - un moteur électrique ou hydraulique qui fait tourner les pales autour de leur axe longitudinal.

Record 7 1986-09-30

English

Subject field(s)
  • Milling (Machine-Tooling)
CONT

This device, when engaged, eliminates the backlash(play) between the nut and the table leadscrew permitting the operation of climb(down) milling... Two independent nuts are mounted on the lead screw. These nuts engage a common crown gear which in turn meshes with a rack. Axial movement of the rack is controlled by the backlash eliminator engaging knob located on the front of the saddle. By turning the knob "in", the nuts are forced to move along the leadscrew in opposite directions, removing all backlash.
