Abstract
A spindle for a spinning or twisting machine comprises a guiding tube, which supports a neck bearing and a step bearing for a rotatably supported shaft. In proximity to the neck bearing, the guiding tube is supported by means of a metal membrane in a bearing housing, which is connectable to a spindle rail. The membrane is relatively rigid in radial direction; however, with respect to tilting motions of the guiding tube, it is very flexible. In the area of the step bearing, the guiding tube is supported against the bearing housing by means of a radial spring.
Claims32
A spindle for spinning or twisting machines, said spindle comprising:
- a rotatable shaft,
- a neck bearing and a step bearing supporting the shaft,
- a guiding tube supporting the neck bearing and the step bearing, and
- a bearing housing supportingly connected to the guiding tube in an area of the neck bearing by means of a membrane, said bearing housing being connectable to a spindle rail,
- wherein said membrane is relatively rigid in a radial direction and relatively resilient in an axial direction to thereby form a hinge for the guiding tube about a tilting axis at a level of the membrane which is flexible with regard to tilting movements of the guiding tube, and
- wherein said guiding tube is supported radially with respect to the bearing housing by a radial spring in an area of the step bearing such that said radial spring opposes tilting movements of the guiding tube about the tilting axis.
A spindle for spinning or twisting machines, said spindle comprising:
- a rotatable shaft,
- a neck bearing and a step bearing supporting the shaft,
- a guiding tube supporting the neck bearing and the step bearing, and
- a bearing housing supportingly connected to the guiding tube in an area of the neck bearing by means of a membrane, said bearing housing being connectable to a spindle rail,
- wherein said membrane forms a hinge for the guiding tube which is flexible with regard to tilting movements of the guiding tube,
- wherein said guiding tube is supported radially with respect to the bearing housing by a radial spring in an area of the step bearing, and
- wherein the membrane is provided above the bearing housing with a covering, a space between the membrane and the covering being filled with a damping medium.
