Definitions
- the invention relates to a pressure roller for a yarn feed mechanism, the pressure roller having an axle, a hub rotatably held on the axle, on which a roller shell can be arranged or is arranged, and a roller bearing with an outer ring and an inner ring, the outer ring being non-rotatable with the hub is connected and wherein the inner ring is supported by at least one elastic support ring relative to the axis.
- thread feeders are used to convey and stretch threads, in which the thread is guided on the circumference of a drive shaft or drive roller, which interacts with an adjacent pressure roller.
- the thread is guided in the nip formed between the pressure roller and the drive shaft.
- the pressure roller is pivotable, so that an axis-parallel arrangement is possible.
- the pivoting of the pressure roller is realized by a self-aligning bearing of the roller shell on an axis.
- a pressure roller is known from the document DE 102010009467 A1, in which the roller shell is supported via a roller bearing clamped in the radial direction on an axle of the pressure roller with the interposition of an elastic support ring between the inner ring of the roller bearing and a holding segment of the axle.
- the inner ring and the holding segment each have a groove for accommodating the support ring, as a result of which an improved mounting of the roller shell on the axle can be achieved.
- a sleeve is pressed onto the holding segment to seal the free end of the holding segment and for reliable fixing.
- a holding disk is arranged on an axial free end section of the holding segment for fixing purposes.
- the tilting capacity of the roller shell is determined.
- the groove width is the distance between the pressed-on end of the sleeve and a supporting collar lying opposite it of the axis and alternatively fixed by a recess formed circumferentially in the holding segment.
- the object of the invention is to provide an improved pressure roller which, in particular, enables simple assembly and disassembly of the pressure roller and, more preferably, adjustment of the ability to tilt the hub or the roller shell.
- the axle of the pressure roller is formed from at least two separate axle segments, with one axle segment forming a holding segment for holding the pressure roller and the other axle segment forming a support segment for supporting the inner ring via the elastic support ring, with the holding segment and the support segment being in the longitudinal direction of the axle , So in the axial direction, are detachably connected to each other.
- Detachable within the meaning of the present invention is understood to mean a non-destructive detachment of components connected to one another, which means that the components to be connected and to be detached, which according to the invention are the holding segment and the support segment, can be detached again and again without damage impairing the function of the connection and the detachment allows.
- a multi-part axle is thus now provided, with the holding segment being provided for holding the pressure roller and the support segment for supporting and fixing the roller bearing on the holding segment.
- the functional division of the axis into two separate components, which are now detachably coupled to each other, enables very easy assembly and disassembly of the pressure roller.
- individual components such as the hub, the roller shell, the roller bearing and the support ring can be replaced independently of one another and as required, without the entire pressure roller having to be replaced, for example if one of these components is worn.
- the pinch roller can also be replaced by individual ones Components can be easily modified as needed without having to completely replace the pinch roller. In this way, a roller shell that is matched to the thread can be easily arranged on the pressure roller.
- the ability of the pressure roller to tilt can also be adjusted to the thread to be processed simply by exchanging the support ring.
- the support segment is designed to keep the elastic support ring clamped between the inner ring and the support segment in the radial or orthogonal direction to the axis when the pressure roller is in the mounted state. As a result, the support ring can be reliably positioned and fixed.
- the holding segment and the support segment are preferably designed to enclose the elastic support ring in a non-contact manner in the axial direction of the axle.
- the bezel maintains the tilting ability of the pinch roller.
- This can be provided, for example, in that the support ring is at a distance in the axial direction of the axis from a section of the holding and support segment that encloses the support ring. More preferably, the support ring rests on a support groove formed with the inner ring in the axial direction of the axis on the edges of the support groove, as a result of which the ability to tilt can be adjusted in a defined manner.
- a defined desired tiltability is alternatively or additionally by selecting an elastic support ring with defined material properties , In particular provided with a defined hardness, and / or a defined geometry.
- the holding segment and the support segment each have a support collar which, when the pressure roller is in the mounted state, is arranged opposite one another for enclosing the support ring or for arranging the support ring between them.
- the support collar of the holding segment is further preferably formed by a front end of the holding segment. That The front end has a smaller outer diameter than the inner diameter of the inner ring, the front end partially overlapping the inner ring in the mounted state of the pressure roller in the axial direction.
- the outer diameter of the support collar of the holding segment is particularly preferably equal to the outer diameter of the support collar of the support segment.
- the outside diameter of the support collar of the support ring is preferably smaller than the inside diameter of the inner ring, the support collar of the support segment partially overlapping the inner ring in the axial direction when the pressure roller is in the mounted state.
- the elastic support ring can be reliably positioned in the region of the inner ring and, if necessary, fixed.
- the support collar of the retaining segment and the support collar of the support segment are at the same distance from a respective associated outer edge of the inner ring.
- the holding segment and the support segment are detachably connected to one another by means of a screw, snap-in, plug-in or clamp connection. More preferably, the holding segment and the support segment are designed with different latching, plugging or clamping positions in the axial direction in order to achieve a needs-based axial enclosure of the support ring, in particular depending on its configuration, as described above by way of example, and/or the desired tiltability of the pressure roller be able.
- the holding segment and the support segment are particularly preferably connected to one another by means of a screw connection, as a result of which the holding segment and the support segment can be formed cost-effectively and are easy to connect to one another and also to detach from one another.
- the screw connection can be provided and designed in such a way that the screw bolt is provided with the holding segment or the support segment and the screw thread or the bolt receptacle with the other of these two components.
- the screw, snap, plug or clamp connection via a releasable safeguard against unintentional release or loosening of the connection, for example due to vibrations or to compensate for play between the respective positive or non-positive locking components.
- the security can be provided in the form of a detachable adhesive connection, which is introduced in a defined manner between the operatively connected positive or non-positive locking components of the screw, snap-in, plug-in or clamp connection in order to glue them together.
- a detachable adhesive connection is to be understood as meaning an adhesive connection whose adhesive or holding force can be overcome by means of force and/or temperature to detach the adhesive connection without damaging the material of the positive or non-positive connection components.
- a further elastic support ring is preferably arranged between the holding segment and the inner ring, in particular clamped by these components.
- improved running smoothness can be achieved through vibration damping of the pressure roller, which has a positive effect on wear and thread guidance.
- the additional elastic support ring enables the pressure roller to be deflected reliably within a defined range.
- the holding segment in departure from the prior art, is no longer made of aluminum, but of a steel-containing material, which more preferably has a corrosion layer, for example by means of a burnishing or chrome plating of the holding segment, at least in a section area that is freely accessible on the outside of the pressure roller is provided. This can further improve the life of the pinch roller.
