Abstract

Cam gear for textile machines, especially for pattern controlling of warp-knitting (chain stitching) machines. Generally, the development concerns a cam gear for textile machines having cams. The present configuration avoids the interferences, caused by oscillations, in the cam gears of textile machines. One advantage is that the occurring oscillations are influenced, and resonance phenomena are avoided, within the practical range of the normal rotation speed of textile machines. The present development accomplished a result, whereby the rest areas of the cam profile of the cam are configured as curved rest area, of which each individual one has a variable rest height, which corresponds only in one single point with the required rest height, and which is assigned to each curved rest area, in reference to the reversal of the direction of movement of the transition, as well as to each curved rest area, in reference to a range of transition without displacement, to a portion of the cam which exceeds the corresponding rest height. The cam gear is utilizable for the gear systems of the working mechanism of textile machines, for instance for pattern controlling of warp-knitting machines,…
