Abstract

A gear reducer (1) comprising a worm (4) and a crown wheel assembly (6) in turn comprising a crown wheel (8) which is connected/disconnected to/from a drive shaft (10) by means of a torque limiter (11) mounted on this latter. The gear reducer (1) is characterised in that the drive shaft (10) and the torque limiter (11) are comprised in a cartridge (200) which can be extracted/inserted from/in a cavity (100) obtained in the crown wheel assembly (6) according to an axial direction (3) and in accordance with two opposite senses ( (Fl) (F2)) without the need to disassemble the worm (4).
