<p>The gearmotor 23 makes a motor component available at both longitudinal ends, generally in the form of countersunk shafts 02, 03. The shaft 02, available on the motor 2 side, represents an extension of the motor shaft proper, that is, of the drive shaft of the reduction gear with which it forms a single body. The shaft 02, available at the end of the motor 2 is driven with the speed of the latter, about 2800 r.p.m., while the shaft 03, available at the end of the reduction gear 3 is driven at a speed of 432 r.p.m. Both ends are provided with a fitting flange 30, 30'. The shafts 02, 03 have a polygonal section and act as couplings. The structure 5 with which the apparatus is provided, has a pair of diametral bolts 7 which co-operate from time to time with two complementary components 8 and also with two pairs of references 8' which are also complementary. <IMAGE></p> |
