<p>Planetary reduction gearing mounted in the tube (3) of a tubular motor and comprising at least one input stage (10) and one output stage (16) in which the satellite gear carrier (17b) is secured to the output shaft (17) of the reduction gearing. The ring gear of the reduction gear consists of two parts (6, 7) which are immobilised rotationally in the tube (3) and one (6) of which meshes with the satellite gears (10, 13) of the input stage and the other (7) of which meshes with the satellite gears (16) of the output stage. The two ring gear parts are connected together by a connection piece (8) axially interlocked in each of the two ring gear parts and fixed to the tube (3). The immobilisation of the ring gear is better provided, the diameter of the output shaft may be greater and the reduction gearing may be designed in a modular form. <IMAGE></p> |
