Description

Kazdy segment 1 ma zewnetrzne ucha 4 i wewnetrzne ucho 5, przy czym przez ucha te przechodzi na wylot pret 6 osadzony obrotowo z obustronnie osadzonymi na nim ciasno podkladkami 7. Ponadto pret 6, przed wysunieciem sie jest zabezpieczony z jednej strony zawleczka 8, a z drugiej strony przy pomocy spedzen 9, wykonanych na precie 6. Miedzy stykajacymi sie plaszczyznami uch 4 i 5 oraz ucha 4 i podkladki 7 znajduja sie obwodowe wystepy 10, tworzace z tymi plaszczyznami labirynt uszczelniajacy.W czasie ruchu, lancuch wedlug wynalazku wykonany z tworzywa sztucznego i majacy budowe przegu¬ bowa latwo opasuje rolki napinajace o malej srednicy i prawidlowo oraz cichobieznie wspólpracuje z kolami: podpierajacym i podrzucajacym oraz drabinkowymi kolami napedowymi. Wystepuja przy tym stosunkowo male naprezenia od sil dynamicznych. PL PLEach segment 1 has outer lugs 4 and an inner lug 5, and through these lugs the rod 6 is pivotally mounted with washers 7 tightly mounted on it on both sides. Moreover, the rod 6 is secured on one side with a cotter 8 and on the other sides by means of pins 9, made on a rod 6. Between the contact surfaces of the lugs 4 and 5 and the lugs 4 and washers 7 there are peripheral protrusions 10, forming a sealing labyrinth with these planes. During movement, the chain according to the invention is made of plastic and The articulated structure easily fits tightening rollers with a small diameter and works properly and silently with the supporting and tossing wheels as well as with ladder drive wheels. There are relatively low stresses due to dynamic forces. PL PL
