Abstract
Tato diplomová práce se zabývá popsáním hlavních mechanismů šicích strojů. Dále bylo experimentálními metodami zjišťováno chování šicího stroje DECO 2000 firmy AMF REECE. Bylo zjištěno rozložení intenzity zvuku v okolí stroje a měřeno zrychlení vybraných komponent. Byl analyzován vybraný mechanismus s cílem snížit vibrace a hluk stroje. Byla provedena analýza vačky jehelního mechanismu. Proběhla úprava rozložení hmoty s cílem snížit nevyváženost vačky a upravila se její zdvihová závislost. Původní sinusová vačka se nahradila vačkou bezrázovou. Výsledky byly ověřeny pouze teoreticky.
This diploma work is engaged in description of main mechanisms sewing machines. After the behaviour sewing machinery DECO 2000 of company AMF REECE was found. It was found distribution of intensity sound round machinery and it was measured acceleration of choice component. Choice mechanism was analyzed with the goal to reduce vibration and noise. It was done analysis cam of needle mechanism. Modification of design was done for reduce evenness of cam and it was adjusted lift dependence. Original sinusoidal cam was replaced by reflexless cam. Results were tested only in theory.
