Zusammenfassung:	Systems and methods for drilling a borehole are provided. One system includes a continuously variable transmission. An input shaft of the continuously variable transmission is coupled to a power supply. An output shaft of the continuously variable transmission is coupled to one or more system components such that the continuously variable transmission controls rotation of the one or more system components. One method for drilling a borehole includes supplying power to an input shaft of a continuously variable transmission. The method also includes controlling rotation of one or more system components using the continuously variable transmission during drilling of the borehole. The one or more system components are coupled to an output shaft of the continuously variable transmission. Also provided is a borehole that is drilled by this method. L'invention a trait à des systèmes et des procédés permettant de percer un trou de forage. Un système comprend une transmission à variation continue. Un arbre d'entrée de la transmission à variation continue est couplé à une source d'alimentation. Un arbre d'entrée de la transmission à variation continue est couplé à un ou plusieurs composants de système de façon que la transmission commande la rotation desdits composants de système. Un procédé de percement d'un trou de forage consiste à fournir de l'énergie à un arbre d'entrée d'une transmission à variation continue. Ce procédé consiste également à commander la rotation d'un ou plusieurs composants de système au moyen de la transmission à variation continue pendant le percement du trou de forage. Lesdits composants de système sont couplés à un arbre de sortie de la transmission à variation continue. L'invention concerne également un trou de forage qui est percé au moyen de ce procédé.
