Abstract
Mejoras en la construcción de transmisiones de husillo roscado, consistentes en un husillo roscado con ranuras de rosca de sección transversal circular, en una tuerca con ranuras de rosca complementarias y bolas que están situadas en una corona cerrada de bolas en el canal de movimiento de bolas formado por las ranuras de rosca de husillo rascado y tuerca, caracterizadas porque la subida de cada ranura de rosca es menor que el producto del diámetro de las bolas y el número de ranuras y de rosca.
