Planetary gear for being connected with electric motor of drive unit of rolling stabilizer of motor vehicle, has planetary wheel designed as elastic spring gear wheel with hub connected with rim contacting external and internal teeth

摘要

#CMT# #/CMT# The gear (1) has a central sun wheel (2) comprising external teeth (3) and a pair of two planetary wheels (4, 5) arranged around the sun wheel in a radial plane. A hollow wheel (6) has an internal teeth (7) and a planetary wheel carrier (9) supporting the planetary wheels. Each planetary wheel has two axially lying together and axially connected gear wheels, where one of the wheels is designed as tangential and radially elastic spring gear wheel with a central hub connected with an outer gear rim by elastic flexible arms. The gear rim is in contact with the external and internal teeth. #CMT#USE : #/CMT# Planetary gear for being connected with an electric motor of a drive unit of a rolling stabilizer of a motor vehicle (all claimed). #CMT#ADVANTAGE : #/CMT# The design of the gear avoids play existing in the gear over an internal pre-loading and/or to absorb zero crossing. The gear wheel is designed as tangential and radially elastic spring gear wheel that is radially soft, enables over sizing of the gear rim and/or teeth profiles, thus ensuring play-free engagement of rim of the spring wheel in internal toothing of a hollow wheel during starting and/or direction of rotation change of the planetary gear, and hence avoiding rattling noises in a safe manner during starting. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of a planetary gear. 1 : Planetary gear 2 : Central sun wheel 3 : External teeth 4, 5 : Planetary wheels 6 : Hollow wheel 7 : Internal teeth 9 : Planetary wheel carrier.
