Electric starter incorporating a base plate supporting the carcase of its electric motor and the yoke of its contactor

摘要

An electric starter comprising a base plate supporting the housing of its electric motor and the yoke of its contactor, wherein the base plate has a central bore in which is placed a bearing maintained in position by means of a disc of plastics material moulded over the plate and which further constitutes the outer ring gear of an epicycloidal reduction gear placed between the electric motor and the shaft of the starter actuator. The disc may further include a lateral lug constituting support for the pin of the actuator lever. A flange made around the ring may form a seal between the housing of the electric motor and the base plate. The invention is more particularly applicable to electric starters for internal combustion engines.
