Abstract
In the case of a spinning or twisting spindle to be arranged vertically, having a spindle shaft which is disposed in a spindle bearing housing by means of a step bearing and a bolster which is constructed as a roller bearing, it is provided that the rollers of the roller bearing are guided such that, at least when the spindle shaft rotates, they are aligned diagonally with respect to the axis of the spindle shaft in such a manner that they exercise an axial thrust in the direction of the step bearing on the spindle shaft.
Claims19
A spinning or twisting spindle to be arranged vertically, comprising:
- a spindle bearing housing,
- a bolster constructed as a roller bearing disposed in the spindle bearing housing,
- a step bearing disposed in the spindle bearing housing at an axial location spaced from the roller bearing,
- a spindle shaft supported in the spindle bearing housing by the roller bearing and the step bearing,
- and roller bearing guide structure for guiding rollers of the roller bearing so that the guiding rollers are inclined with respect to a spindle shaft rotational axis so as to engage the spindle shaft surface to provide an axial thrust force on the spindle shaft toward the step bearing in response to rotation of the spindle shaft during operational use of the spindle, thereby preventing undesired movement of the spindle shaft in the direction from the step bearing toward the bolster.
