Description

Przedmiotem niniejszego wynalazku jest odmiana tego urzadzenia, wedlug którego wszystkie kola glównego napedu napedza¬ ne sa zapomoca wspólnego lancucha bez konca.Na rysunku uwidoczniona jest konstruk¬ cja tej odmiany.Na glównej ramie 10 maszyny osadzo¬ ne jest obrotowo na wale 12 glówne kolo U, które napedzane jest za posrednictwem lancucha 15 przez kolo lancuchowe 14, u- mocowane na wale 13. Lancuch 15 przecho¬ dzi do oslony 16, zlaczonej z podstawa wrzecion, wykonana w ksztalcie skrzynki; w oslonie umieszczone sa dwa luzno obra¬ cajace sie kola lancuchowe 17 oraz kolo lancuchowe 23, osadzone na wale napedo¬ wym 7 wrzecion. Kola 17 prowadza lancuch 15 w ten sposób, ze obejmuja kolo 23 na dostatecznie duzym obwodzie. Do nacia¬ gania lancucha 15 sluzy kolo naprezajace 18. Kola lancuchowe 19 sa kolami kierun- kowemi, wobec czego lancuch prowadzony jest pionowo zgóry nadal przez oslone 16.Przy podnoszeniu i opuszczaniu podsta-wy wrzecionowe} nastepuje zmniejszenie wzglednie powiekszenie obrotów walu 7 w *ten sposóbt jaik to-opisane jest w glównym patencie. PLThe subject of the present invention is a variation of this device, according to which all the main wheels of the drive are driven by a common endless chain. The figure shows the construction of this variation. The main frame 10 of the machine is rotatably mounted on the shaft 12, the main wheel U which is driven via a chain 15 by a chain wheel 14 attached to the shaft 13. Chain 15 passes into a housing 16 connected to the base of the spindles, made in the form of a box; in the cover there are two loosely rotating chain wheels 17 and a chain wheel 23, mounted on the drive shaft 7 of the spindles. The wheels 17 guide the chain 15 such that they encircle the circle 23 with a sufficiently large circumference. A tension pulley 18 is used to stretch the chain. The chain pulleys 19 are directional pulleys, so that the chain is guided vertically through the cover 16. When lifting and lowering the spindle bases, the rotation of the shaft 7 is reduced or increased. this method as it is described in the main patent. PL
