Definitions
- the invention relates to a lever for heald frame of a loom with a freely designed outer and inner shape.
- a lever for the transmission of movements to heald frames in textile machines is known from EP 0 595 380 B1.
- This lever consists of two interconnected congruent plates, of which at least one plate has a first surface into which a plurality of lines which can cross one another are incorporated. One end of each line ends in a corresponding seat for a bearing.
- One bearing of the lever forms a deflection point, while other bearings form pivot points for e.g. Form tie rods.
- Ductile iron or a cast alloy to introduce a hydraulic flow channel.
- a metallic, cross-sectional tubular, two-part or multi-part component is inserted into the mold, which is cast with the workpiece.
- the workpiece equipped with at least one integral flow channel can, although not explicitly mentioned, also be a machine part for a weaving machine.
- the disadvantage here is that such workpieces are not low in mass and a relatively high one
- the deflection lever then consists of outer individual parts and at least one inner individual part arranged between the outer individual parts.
- the inner individual part has recesses substantially transversely to its outer surfaces, which are connected to the inner surfaces of the outer individual parts, which give the machine part functional properties when stacked and the individual parts are subsequently connected in the form of a stack package.
- the bell crank has at least one
- Deflection point with bearing and a plurality of articulation points with bearing and the recesses and / or formations form lubricant channels in the machine part when the outer individual parts and the at least one inner individual part are stacked.
- the individual parts can be made from one
- Stack package of a plurality of lamella-like parts which are connected to one another in a stack consist, as is known inter alia from EP 1 420 147 A1.
- the outer individual parts of the deflection lever can consist of a stack of lamellae joined together.
- the inner part with the recesses can consist of a stack of lamellae, if such a configuration facilitates the transport of the lubricant to the bearing in question.
- a low manufacturing cost of the machine part according to the invention is achieved in that the outer individual parts and the inner individual part are plate-like in shape and in one piece or the individual parts consist of lamella-like individual elements.
- the individual parts or the individual elements can be produced by punching from sheet metal strips and assembled into so-called punch packages, as are known in the manufacture of rotors, stators in electric motor construction or from transformer technology.
- assembly aids can be provided not only when the machine part consists of only three one-piece individual parts, but also when each individual part is produced from a punch package of lamella-like individual parts. Furthermore, for the same purpose, a plurality of connecting means, to which recesses in the outer individual parts are assigned in alignment, can preferably be present on the abutting surfaces of the inner individual part.
- the outer individual parts and the inner individual part can be of the same or different material properties, in order to obtain an inseparable connection between the individual parts that is sealed against leakage.
- Figure 1 is a perspective view of a lever for heald frame of a weaving machine in the execution of an individual parts
- Figure 2 shows the inner part of the bellcrank provided with recesses for forming lubricant channels in a perspective view and Figure 3 shows the outer individual parts with the inner part of the bell crank in a perspective view.
- the bell crank shown in Figure 1 consists of a first outer part 2, a second outer part 3 and an inner part 4 arranged between the first outer and second outer parts 2, 3.
- a bearing 6 accommodated in a recess 5 of the bell crank 1 forms the deflection point of the deflection lever 1.
- the bearing 6 is received by a shaft, not shown here, which is symbolically indicated by its longitudinal center axis 7.
- the deflection lever 1 has at least one at the deflection point
- Lubricant supply 8 in order to supply the bearing 6 and also the articulation points of the deflection lever equipped with bearings 9, 10, 11 with lubricant.
- the bearings 9, 10, 11 are supplied with lubricant via lubricant channels 12, 13, 14, as shown in FIG. 2, which when the plate-like outer individual parts 2, 3 shown in FIG. 3 are assembled with the plate-like inner individual part 4 of the bell crank 1 arise.
- the lubricant channels 12, 13, 14 integrated in the UrhieHkhebe ⁇ 1 are shown as essentially linearly guided external channels, which extend from the lubricant feeds 8 in the area of the recess 5 for the bearing 6 to the recesses 15, 16, 17 for bearings 9, 10, 11 are guided.
- the bearings 9, 10, 11 form articulation points of the bell crank 1.
- the individual part 4 preferably has centering means on both abutment surfaces 4 a in the manner of pins 18 which engage in centering bores 19 of the outer individual parts 2, 3.
