Title
(EN) INTEGRATED SLEW DRIVE
(FR) ENTRAÎNEMENT DE BALAYAGE INTÉGRÉ
Abstract
(EN)
A slew drive comprises a slew drive housing which includes a first distal housing section and a second distal housing section. The first distal housing section includes a threaded section, operative to receive a threaded plug and the second distal housing section includes a groove operative to receive a retaining ring. A worm gear is secured to the slew drive housing by a first tapered roller bearing and a second tapered roller bearing. The worm gear comprises a central threaded section, a first distal shaft section having a first shoulder, and a second distal shaft section having a second shoulder. The central threaded section engages the teeth of a worm wheel, the first tapered roller bearing is seated on the first distal shaft section, abutting the first shoulder and the plug, and the second tapered roller bearing is seated on the second distal shaft section, abutting the second shoulder and the retaining ring.

L'invention concerne un entraînement de balayage comprenant un boîtier d'entraînement de balayage qui comprend une première section de logement distale et une seconde section de logement distale. La première section de logement distale comprend une section filetée, conçue pour recevoir une fiche filetée et la seconde section de logement distale comprend une rainure conçue pour recevoir un anneau de retenue. Un engrenage à vis sans fin est fixé au boîtier d'entraînement de balayage par un premier roulement à rouleaux coniques et un second roulement à rouleaux coniques. L'engrenage à vis sans fin comprend une section filetée centrale, une première section d'arbre distal ayant un premier épaulement et une seconde section d'arbre distal ayant un second épaulement. La section filetée centrale vient en prise avec les dents d'une roue à vis sans fin, le premier roulement à rouleaux coniques est logé sur la première section d'arbre distal, venant en butée contre le premier épaulement, et la fiche et le second roulement à rouleaux coniques est logé sur la seconde section d'arbre distal, venant en butée contre le second épaulement et la bague de retenue.
