ABSTRACT:
A device for reducing ventilation loss of a high-speed gear mechanism with a gear housing NS intermeshing gears, which are surrounded by a casing and to which lubricant is supplied in the engagement area for the purpose of reducing friction. The gear mechanism consists, in a known manner, of a gearwheel and a pinion that intermeshes therewith. Utilizing the pressure that is automatically established in the tooth engagement and disengagement area, only the pinion is encapsulated over area of more than 180.degree. of its peripheral distance. The end of the encapsulation in the tooth disengagement area is designed so that there is constant enlargement of the uncovered cross-sectional area between the pinion and the gearwheel. Additionally, and the encapsulation is sealed on both sides relative to the non-toothed shaft area of the pinion.
