Abstract
"ENGRENAGEM DE COMUTAçãO DE RELAçãO DE TRANSMISSãO EVOLUTIVA" Trata-se a presente invenção de uma engrenagem de transmissão de energia mecânica mediada por corrente ou correia que possibilita comutações de relação de transmissão sem que para que sejam efetuadas haja a necessidade de interrupções na transmissão, de onde advém o termo evolutiva, para finalidades diversas no âmbito de sistemas de engrenagens. é constituída basicamente de dois discos, (1) e (2), associados fisicamente através de um cilindro oco (9), podendo este ser fixado diretamente em eixo, ou em sistema tipo catraca, sendo o segundo (2) dotado de perfurações ou pontos de apoio (8), de modo que haja, para cada uma destas, uma perfuração no primeiro (1), através das quais se transpassam os pequenos eixos de apoio (6), que são de dois tipos básicos, dentada com rodinhas ou sem rodinhas nas suas extremidades livres, que correspondem àquelas mais afastadas do espaço interdiscos, sendo que as rodinhas estão representadas pelo número (7), bem como de uma engrenagem convencional dentada (3) fixada no cilindro oco (9), além de duas engrenagens segmentadas subsequentes, (4) e (5), que são, cada qual, constituídas por quatro frações idênticas entre si, que apresentam, como se pode observar na figura 1 (porção envolvida pelas circunferências tracejadas, indicativas de detalhamento), uma projeção de acoplamento (10) habilitadas a encaixarem-se aos pontos de apoio (8), ou seja, para cada ponto de apoio (8), há uma projeção correspondente, seja em (4) ou em (5)."EVOLUTIONARY TRANSMISSION RELATIONSHIP SWITCHING GEAR" This invention is a mechanical energy transmission gear mediated by a chain or belt that allows for transmission gear changes without the need for interruptions in the transmission, whence the term evolutionary, for different purposes in the context of gear systems. basically consists of two discs, (1) and (2), physically associated through a hollow cylinder (9), which can be fixed directly on the shaft, or in a ratchet type system, the second (2) being equipped with perforations or support points (8), so that for each of these there is a perforation in the first (1), through which the small support axes (6), which are of two basic types, without casters at their free ends, which correspond to those furthest from the interdisc space, and the casters are represented by the number (7), as well as a conventional toothed gear (3) attached to the hollow cylinder (9), in addition to two gears subsequent segments, (4) and (5), which are each constituted by four fractions identical to each other, which present, as can be seen in figure 1 (portion surrounded by dashed circles, indicative of detail), a projection of steel (10) enabled to fit the support points (8), that is, for each support point (8), there is a corresponding projection, either in (4) or (5).
