Bearing for spindles in spinning or twisting machines

Abstract

Spindles of spinning and twisting machines have a rotatable shaft supported in a bearing housing. The bearing housing comprises a neck bearing, a step bearing as well as a radially movable step bearing tube, which is arranged in an oil bath. The diameter of the shaft at the step bearing tube measures at the most six times the diameter at the neck bearing. Preferably, the diameter at the step bearing tube measures no more than between 3 and 3.5 mm. Thus the absolute bearing clearance in the step bearing tube can be significantly reduced, which results in a quieter running of the spindle and to a reduction in power consumption for the drive.
