Spiral Springs at stainless steel horizontally and vertikal / Neff Gewindetriebe

DURASPRING Spiral springs can be installed in both, horizontal and vertical applications: Horizontal installation Vertical installation Our DURASPRING Spiral Springs are manufactured speci[1]fically to suit horizontal or vertical operation. For horizontal applications, the extension is reduced (see tabulations). Horizontal installation Springs used horizontally are formed for particularly for uniform running in that the overlap between coils is increa[1]sed. In this way »sagging« is reduced, particularly for longer extension lengths, and transverse stability is significantly improved. In the case of horizontal installation of the springs, placing the larger diameter adjacent to the area of swarf produc[1]tion is recommended. Vertical installation As a matter of principle, vertically installed DURASPRING achieve larger extension lengths than horizontal types. The critical design factor for this type is the force produced, as the springs must also work against gravity. Vertical types therefore have a high starting force, guaranteeing that the DURASPRING draws out rapidly when starting/ extending with the machine movement. For efficient protection and optimum operation, vertical spirals should be mounted with the large diameter at the top. Flanges (optional) Simple centring flanges are required at both ends of the DURASPRING for installation (see order sheet). These flanges must permit rotary movements of the spring that may occur, in order to prevent damage to the springs. The springs must be guided so that they can move freely. It is not permitted to screw and/or rivet them. When using flanges, the spindle diameter SD is reduced by 6 mm compared to the values given on the following pages.
