摘要

Bearing assemblies for supporting opposite stub shafts of an upper drawing roll of a textile sliver drawing frame. Each bearing assembly includes a bearing sleeve having an inner cylindrical surface and an open end through which a respective stub shaft projects into the bearing sleeve; rolling bodies disposed circumferentially between the stub shaft and the inner cylindrical surface of the bearing sleeve; a spring supporting member disposed in the bearing sleeve and being affixed to the inner cylindrical surface thereof; and a holding element disposed in the bearing sleeve between the spring supporting member and the end face of the stub shaft. The holding element is axially displaceable relative to the bearing sleeve. A spring is disposed in the bearing sleeve between and in contact with, the spring supporting member and the end face of the stub shaft. The drawing roll is axially shiftable relative to the bearing sleeves of the first and second bearing assemblies against the force of the spring towards which the roll is shifted.
