  • Publication number: 20190241169
    Abstract: An arrangement of screws for a screw compressor for a utility vehicle includes at least one female screw and at least one male screw. The female screw and the male screw each have teeth that engage with one another. The teeth of the female screw have a roll-off tooth flank which is provided for rolling-off a tooth flank of the male screw. The roll-off tooth flank has a convexly rounded roll-off tip region in the tip region, which has a first radius, wherein a tooth base is provided between two neighboring teeth of the female screw, which is connected to the roll-off tip region via a flat transition region. The tooth base between two teeth of the female screw is substantially concavely rounded and has a second radius, wherein the second radius is approx. 2.5 to 3.5 times greater than the first radius.
