Actuating drive with an electric motor and a planetary gear

摘要

#CMT# #/CMT# The drive (1) has a planetary gear mechanism (3) operatively connected to an electric motor (2), and a ring gear (4) connected to an end bracket (13) with free end. A set of planet gears (6a, 6c) includes peripheral external teeth and front surface relative to assembly direction in an area of the teeth. A set of angle areas is provided at an end of the ring gear at a predetermined angle position relative to a planet carrier (5), where axial spacing differs from another axial spacing between the front surface of the planet gears and one of the angle areas. #CMT#USE : #/CMT# Control drive. #CMT#ADVANTAGE : #/CMT# The drive efficiently ensures economical and time-decoupled simple and rapid assembly of planet gears in the ring gear without increasing the manufacturing cost of the drive. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a control drive. 1 : Control drive 2 : Electric motor 3 : Planetary gear mechanism 4 : Ring gear 5 : Planet carrier 6a, 6c : Planet gears 13 : End bracket 18 : Housing canister.
