摘要

AN ELECTRIC MOTOR-SPEED REDUCER UNIT FOR DRIVING ACCESSORIES OF MOTOR VEHICLES SUCH AS WINDOW GLASSES The unit comprises an armature (1) provided with a rotary output shaft (2) and a speed reducer (3) provided with a shaft (6) supporting a worm (5) engaged with a form wheel (4) for driving the accessory, and an articulated coupling (20) between the two shafts (2, 6) which are disposed in end-to-end relation. The coupling (20) between the two shafts comprises a male member (8) disposed in female parts (9, 11) which are conjugate with the male member (8) and formed in confronting end portions (2a, 6a) of the two shafts (2, 6), and a single bushing (12) in which the end portions (2a, 6a) are inserted and which ensures the support and the axial alignment of the two shafts (2, 6).
