Abstract

"CAIXA DE TRANSMISSãO PARA BICICLETAS". A presente invenção é que em cada volta do central, percorre-se uma área maior com menos esforço físico. A dita caixa é constituída por caixa protetora (10), na qual protege os elementos de poeiras, choque e outros inconvenientes que possam comprometer o funcionamento do sistema causando desgaste precoce. Dentro da caixa encontra-se o 1° sem-fim (1) acionando a 1¬ coroa (2) que aciona a 2¬ coroa (4) por meio do eixo principal (3). A 2¬ coroa dá movimento ao 2° sem-fim (5) que gira a roda dentada (6) que está fixa ao eixo do mesmo. Os rolamentos localizam-se no 1° sem-fim (1) duas peças, no eixo principal (3) duas peças nas extremidades, no 2° sem-fim (5) duas peças."TRANSMISSION BOX FOR BICYCLES". The present invention is that in each turn of the plant, a larger area is covered with less physical effort. Said box consists of a protective box (10), in which it protects the elements from dust, shock and other inconveniences that could compromise the functioning of the system causing premature wear. Inside the box is the 1st worm (1), activating the 1st crown (2) that activates the 2nd crown (4) through the main axis (3). The 2nd crown gives movement to the 2nd worm (5) that turns the toothed wheel (6) that is fixed to its axis. The bearings are located on the 1st worm (1) two pieces, on the main shaft (3) two pieces at the ends, on the 2nd worm (5) two pieces.
