Abstract

L'invention concerne un coupleur de transmission à vis sans fin. Le coupleur est caractérisé en ce qu'il comprend un élément extérieur tubulaire et un élément intérieur allongé comportant des rainures hélicoïdales complémentaires coopérant de façon à définir un conduit hélicoïdal de passage de billes dans lequel sont disposées plusieurs billes placées en contact mutuel les unes avec les autres, ledit élément extérieur tubulaire comprenant deux manchons tubulaires accouplés rigidement et dont l'un est placé à l'intérieur de l'autre et est pourvu d'une desdites rainures, le premier manchon comprenant une partie qui s'étend à l'extérieur de l'autre manchon. L'invention s'applique à des systèmes de transmission.The invention relates to a worm transmission coupler. The coupler is characterized in that it comprises a tubular outer element and an elongated inner element comprising complementary helical grooves cooperating so as to define a helical ball passage duct in which are arranged several balls placed in mutual contact with each other. others, said outer tubular element comprising two rigidly coupled tubular sleeves, one of which is placed inside the other and is provided with one of said grooves, the first sleeve comprising a part which extends to the outside of the other sleeve. The invention applies to transmission systems.
