Abstract
Un engranaje sin fin con transmisión por bolas, con un husillo y un cuerpo matriz, que presenta una ranura helicoidal interior, complementada por el husillo para formar un canal helicoidal de rodadura de bolas, y que da acogida a una multitud de bolas circulantes sin fin, estando practicado en el cuerpo motriz m n canal de retorno para las bolas, que discurre en sentido axial, mientras que en los dos puntos de transición entre el canal helicoidal de rodadura de bolas por un lado, y el canal de retorno de las bolas, que discurre en sentido axial, están insertadas sendas piezas de desviación en una escotadura de la superficie final de cada caso del cuerno matriz, adaptada a su contorno y que interseca la superficie periférica interior del cuerpo matriz, porque en cada caso sustentan un saliente de desviación para el traslado de las bolas, que consiste en una parte tangencial y una parte curvada siguiente, caracterizado porque el canal de desviación (62) está abierto en su zona periférica opuesta al saliente (figs 9 y 10) y porque las bolas (70) siguen en esta zona una primera superficie limitadora (24), paralela al eje, de la escotadura (20), superficie que enlaza constantemente y de manera sustancialmente tangencial con el fondo (32) de las ranuras matrices.
