The planet deceleration type starter motor comprises a motor, a speed reducing mechanism, a clutch component and an electromagnetic switch, wherein the motor is composed of a stator (11) fixed in a machine shell (8) and an armature (10) supported in the machine shell (8), the speed reducing mechanism is composed of a sun gear (9) fixed on an armature shaft, four planet gears (2) arranged on a wheel stand (3) and meshed with the sun gear, and a spline shaft (6) supported in the machine shell (8) and connected with the wheel stand (3), the clutch component is composed of a clutch (7) sleeved on the spline shaft (6) and a shifting fork (4) connected in the machine shell (8) in a hinged mode and connected with the clutch in a movable mode, and a pull rod (5) in movable connection with the shifting fork (4) is arranged in the electromagnetic switch (1) fixed on the machine shell (8).
Description
Technical field
The utility model relates to a kind of direct current generator, relates in particular to a kind of planetary reduction gear formula actuating motor, belongs to automobile starting motor.
Background technique:As everyone knows, automobile starting motor is made of motor, reducing gear, relay, switch and clutch usually.Because the reducing gear of orthodox car actuating motor adopts common reduction gears mechanism and common clutch, so volume is bigger, can not satisfy the usage requirement of Hyundai Motor.
Summary of the invention:At the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of volume planetary reduction gear formula actuating motor little, in light weight, simple in structure.
To achieve these goals, the utility model by the following technical solutions: it comprises motor, reducing gear, clutch component and magnetic switch; Described motor by be fixed on the stator in the casing, the armature that is bearing in this casing constitutes; Described reducing gear is by being fixed on sun gear on the armature shaft, being located on the wheel carrier with four planetary pinions of this sun gear engagement, being bearing in the splined shaft that is connected with wheel carrier in the casing and constituting; Described clutch component is by being enclosed within clutch on the splined shaft, being hinged on the shift fork that flexibly connects with this clutch in the casing and constituting; Be fixed on and be provided with the pull bar that flexibly connects with shift fork in the magnetic switch on the casing.
Compared with the prior art, the utility model utilizes the planet-shaped reducing gear to substitute traditional gear reducer owing to adopted technique scheme, therefore can realize that reducing gear and motor shaft are concentric, thereby can effectively reduce the volume and weight of complete machine, structure is simple more compact; In addition, because clutch has adopted the edge nested structure, therefore shorten axial dimension, can satisfy the requirement of the little installing space of Hyundai Motor fully.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Among the figure: magnetic switch 1 planetary pinion 2 wheel carriers 3 shift forks 4 pull bars 5 splined shafts 6 clutches 7 casings 8 sun gears 9 armatures 10 stators 11 steel balls 12
Embodiment:The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1: motor by be fixed on the stator 11 in the casing 8, the armature 10 that is bearing in this casing constitutes; Reducing gear is by being fixed on sun gear 9 on the armature shaft, being located at and being bearing in the splined shaft 6 that left end is connected with wheel carrier 3 on the casing 8 with four planetary pinions 2, right-hand members of this sun gear engagement on the wheel carrier 3 and constituting, and the left end of this splined shaft is bearing on the described armature shaft by steel ball 12.On splined shaft 6, the shift fork 4 that is hinged in the casing 8 flexibly connects with this clutch clutch 7 by inner spline housing.Magnetic switch 1 is fixed on the casing 8, is provided with the pull bar 5 that flexibly connects with shift fork 4 in this magnetic switch.
When magnetic switch 1 energising, pull bar 5 promotes shift fork 4 and rotates counterclockwise under the adhesive of electromagnetic force, and shift fork 4 promotes clutch 7 engagements immediately; When relay magnetic switch 1 dead electricity, spring drives shift fork 4 by pull bar 5 and clockwise rotates, and shift fork 4 drives clutch 7 immediately and throws off.
