Zusammenfassung: | The invention relates to a cycloidal roller transmission meant to reduce/amplify rotation speed, with increased kinematic ratio and high efficiency. According to the invention, the transmission comprises an eccentric shaft (1), a circular disc (2) articulated to the eccentric section of the shaft (1) and a cycloidal roller gearing consisting of a wheel with internal cycloidal toothing (4) and several slide blocks, in the shape of some double or triple rollers (3 and 3'), which are eccentrically articulated between two flanges (5 and 5') making one piece by means of some spindles (7) provided with the same eccentricity as the shaft (1), so that a row of rollers (3) is maintained tangent to the disc (2) while the other row of rollers (3') engages with the cycloidal toothing (4).
Invenţia se referă la o transmisie cicloidală cu role, destinată reducerii/amplificării turaţiei, cu un raport cinematic ridicat şi un randament superior. Transmisia conform invenţiei conţine un arbore (1) excentric, un disc (2) circular, articulat la tronsonul excentric al arborelui (1), şi un angrenaj cicloidal cu role, format dintr-o roată cu o dantură (4) cicloidală interioară şi mai mulţi galeţi, sub forma unor role (3 şi 3´) duble sau triple, care sunt articulaţi excentric între două flanşe (5 şi 5´) solidare, prin intermediul unor fusuri (7) prevăzute cu o excentricitate egală cu cea a arborelui (1), astfel încât un rând de role (3) rămâne tangent la disc (2), iar celălalt rând de role (3´) angrenează dantura (4) cicloidală. |
