Description

like bulges an approximately sinusoidal are two parallel to the longitudinal direction of the row Define running profile, rows of trough-like cutouts lying on the other

2. Insert element according to claim 1, with two hung of the cross-sectional shape according to the invention If they are right next to each other at right angles to the row, a further improvement is obtained lowing rows of tub-like bulges and the operating behavior when the sinusoidal gen, characterized in that the sinusoidally running Piofile of the two rows run in rows Profiles of the two rows by 180 ° longitudinally by 180 ° against each other in phase opposite one another are out of phase. are set. A phase shift is fundamental

a flat sheet metal blank by embossing 40 rows 12 and 14 of bulge-like bulges in this sheet metal 16, 18 embossed. with those of the other side directed. The longitudinal direction of the row of tub-like bulges in a row is indicated by the arrow, the tub is arranged longitudinally, with the direction of the row longitudinal direction essentially 45 by the arrow B.

vertically extending tub longitudinal direction, and it can be seen from Fig. 2 that the adjacent

opposite the bulge-free surface areas closing bulges 16, 18 of each row are bulged to the same depth in two directions; Describe a sinusoidal profile and that the sinusoidal an advantageous embodiment, the shaped profiles of adjacent rows are elongated by 180 ° in trough-like bulges. So rows longitudinal direction A are offset.

Claims (1)

In the known insert element according to the German patent claims: see Auslegeschrift 2 018 367, the bulges are only provided in a single direction, 1. Insert element lying between one another, the insert element according to the USA Areas of adjacent machine parts for 5 writing 2931412 in Fig. 2, 3, 10, 11 about the force-fit Connection of this machine-whole surface width continuous indentations, parts, especially for hub connections, from without bulge-free areas, shows that none of them have a flat sheet metal cut reference plane defined by embossing. The depositary of tub-like bulges in these according to the German patent 903 762 consists of Sheet metal cutting with preservation of ausbuch- io a perforated tube, the perforated edges of which are free of growths Surface areas of the sheet metal condition are crimped inwards and outwards and Section, whereby the tub-like bulges do not form any elastic bulges. gen arranged in a row, with for row It has been shown that the insert elements longitudinally essentially vertically vertex - according to the main patent a particularly favorable prayer Longitudinal direction of the trough, and then show drift behavior compared to the 15 if - in a bulge-free Area areas after two cut directions placed right to the longitudinal direction of the tub are bulged to the same depth, seeks - the adjoining tub chewing patents 22107öS, thereby kean-like bulges an approximately sinusoidal shows that - define in a profile running perpendicular to the. So that is also a Section taken in the vertical direction consider a maximum of bulge units per area - the adjoining tub unit achieved.
