Abstract
A gearbox has a main unit and a secondary unit provided with respective casings of respective gear transmissions and with respective hollow shafts connected by means of a drive shaft; the secondary unit transfers motion between two axes forming an angle of less than 180° and which can be removed after having released the drive shaft; the drive shaft is engaged in an angularly fixed and axially sliding manner to the hollow shafts and is axially locked, at least in one direction, by means of an axial retaining device, which is releasable; the axial retaining device is coupled to one of the hollow shafts, at an axial end which is facing towards the other of the hollow shafts; at least one opening may be formed between the two casings, so as to access such an axial end and release the axial retaining device.
