Definitions
- the invention relates to a shuttle loom with the features of the preamble of claim 1.
- the reversing levers of a shank weaving machine produce a reciprocating movement to produce an up and down movement of the heddle shafts.
- the bellcrank thus belong to an oscillating system.
- Such oscillating positively driven systems with not necessarily sinusoidal motion profile have the property of a discontinuous energy flow.
- masses are accelerated, which have to be decelerated again until their reversal point, in order then to be accelerated again.
- such movements occur, for example, on the reed and on the shaft or eccentric machine.
- the reciprocating movement of the return levers is often accomplished via the dobby, i. realized directly above the Webschaftantrieb.
- DE 297 13 383 U1 describes a bearing for shaft levers of shaft looms.
- This bearing is according to its basic structure Rolling bearing with a bearing inner ring and a bearing outer ring, which are arranged coaxially with each other. Between the bearing inner ring and the bearing outer ring rolling elements are arranged in a conventional manner to allow relative rolling of the bearing inner ring and bearing outer ring to each other.
- a rubber membrane is provided as a sealing ring between the bearing inner ring and the bearing outer ring at the end faces. The rubber membrane is fixedly arranged between an outer retaining ring and an inner retaining ring and connects these two retaining rings.
- the reed is designed as an oscillating mass-spring system, wherein coil springs are arranged on the reed, which are compressed in the movement in one direction, while at the same time to the compression of the first spring, one of these opposing spring is expanded.
- this mass-spring system corresponds to that of JP 2001011747 A, with this known mass-spring system not the lever, but the reed is provided.
- DE 24 29 907 A1 discloses a device for bumpless interception of a moving body, in particular a radial arm connected to a torsion bar
- Torsion bars are disadvantageous in that they, to a certain
- angles of rotation also require a defined length.
- the length of a torsion bar is greater, the greater the pivot angle to be realized. This is also the requirement for a compact design (space required)
- the invention is therefore based on the object to provide a shuttle loom, in which energy peaks at the turning points of the track curve of the transmission element can be leveled and which requires less drive energy and is also designed compact and space-saving with respect to the dobby.
- the shank weaving machine comprises at least a pair of heddles, whose counter-movement, by means of which a shed is formed, e.g. can be generated by a dobby as a shedding device, wherein an up and outgoing movement of the heald hives can be generated by an axis between two dead centers and forth pivoting lever, which are on the one hand connected to the heald and on the other hand with the dobby drive.
- the deflecting levers each have a rotary bearing rotating about the axis, wherein the reciprocating levers are impressed by the dobby over the axis and the rotary bearing.
- the rotary bearing is designed as a rotary energy storage with an outer ring for fixing the pivot bearing in the lever and with an inner ring for fixing the pivot bearing on a shaft arranged concentrically to the axis.
- a means is provided between the inner ring and the outer ring, which is arranged in the region between the inner ring and the outer ring and establishes the connection between the inner ring and the outer ring.
- This means arranged in the region between the inner ring and the outer ring at least partially stores the energy introduced by means of the shaft into the means for moving the reversing lever from the first to the second dead center and returns this energy during the reverse movement of the reversing lever from the second dead center back into the first Dead center essentially back off the shaft.
- the energy-storing and energy-returning means in the radial direction is also designed to damp. More preferably, it is the agent is an elastomer, preferably a rubber material having a Shore hardness of 60 to 90, preferably 65 to 75, in particular 70.
- both the inner ring and the outer ring are preferably formed of steel, wherein the steel inner ring and the steel outer ring are connected by preferably vulcanized rubber each other.
- the elastomeric material may also be glued to the inner ring and the outer ring.
- a steel-rubber-steel element may be a basic structure according to commercially available component. It has now surprisingly been found that the component satisfies the requirements for high compactness, energy storage and energy output and vibration behavior and damping behavior in the radial direction as a pivot bearing for lever of shaft looms very well.
- Such a steel-rubber-steel spring element thus offers the possibility of energy storage and energy release and storage in the same component.
- an elastomeric spring is used for this purpose.
- An essential advantage consists in the fact that such an elastomer spring also allows a Shore hardness of the elastomeric spring corresponding damping in the radial direction, without additional this attenuation enabling components are provided.
- a reversing lever is shown in front view, which is provided with a pivot bearing according to the invention.
- the reversing lever 1 is operatively connected to the shaft via a rotary shaft 2 and is pivotable about the axis 6 on a shaft (not shown).
- the rotary bearing 2 has an inner ring 3, which is non-rotatably mounted on the shaft, not shown, and has an outer ring 4, which is non-rotatably seated in the bearing opening of the reversing lever 1 on the inner surface.
- a rubber element designed as a means 5 is arranged as an energy store, which completely fills the area between the inner ring 3 and the outer ring 4 and which is firmly connected both to the outer ring 4 and to the inner ring 3 , This solid compound is preferably produced by scorching.
