Device, the commutator segment of the commutator are arranged on the end face of the rotor afterbody, and described carbon brush component is arranged on institute as end cap
The aperture position of housing is stated, there is carbon brush, described carbon brush is positioned axially and presses in the rotor in the carbon brush component
On the commutator segment of tail end face, there is armature shaft on described rotor, tooth is provided between the armature shaft and the isolator
Wheel decelerator.
Described gear reduction unit includes fixed seat, ring gear, drive shaft and the row being connected in the housing cavity
Star gear, described fixed seat are fixedly connected integrally with ring gear, and described drive shaft passes through described fixed seat, the drive
One end of moving axis is provided with terminal pad, and described terminal pad is provided with several rotating shafts, and described row is socketed in described rotating shaft
Star gear, the end of the armature shaft are socketed with needle bearing, and the needle bearing is plugged on the middle axle position of even described fixed seat
Put, the side face of the armature shaft is provided with gear part, and the flank of tooth in the gear part is meshed with described planetary gear, described
Planetary gear is meshed with the internal tooth of the ring gear.
Described planetary gear material is powder metallurgy.
This structure of the present utility model, because afterbody of the carbon brush component installed in rotor is socketed in rotor with original surround
Side face on compare, there is the effect for reducing volume, while the carbon brush on carbon brush component is pressed on the commutator segment of rotor afterbody,
So that contact surface increases, the armature shaft torque of rotor is effectively increased so that the armature shaft on rotor is after gear reduction unit
Torque is further increased, and will be exported in the torque transmission of the increase to isolator, so just reached torque greatly and had
Effect reduces the technique effect of volume, so as to ensure that the clean boot of diesel engine, and extends engine life.
The utility model is further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
The utility model is specifically described below by embodiment, is served only for carrying out further the utility model
Explanation, it is impossible to be interpreted as the restriction to scope of protection of the utility model.
As shown in figure 1, the utility model discloses a kind of star-like retarding starter of passenger car diesel, including housing 1, direct current
Motor 2, isolator 3 and electromagnetic switch 4, direct current generator 2 and isolator 3 are arranged in the inner chamber of housing 1, and electromagnetic switch 4 is installed
In the side of housing 1, wishbone lever 5 is provided between electromagnetic switch 4 and isolator 3, there is rotor 21 on direct current generator 2, determine
Son 22 and carbon brush component 23, the afterbody of rotor 21 are provided with commutator 212, and the commutator segment 2121 of the commutator 212 is arranged on rotor
On the end face of 21 afterbodys, carbon brush component 23 is arranged on the aperture position of housing 1 as end cap, has carbon brush in carbon brush component 23
231, carbon brush 231 is positioned axially and presses on the commutator segment 2121 of the tail end face of rotor 21, has armature shaft on rotor 21
213, gear reduction unit 6 is provided between armature shaft 213 and isolator 3.
Gear reduction unit 6 includes fixed seat 61, ring gear 62, drive shaft 63 and the planet being connected in the inner chamber of housing 1
