Input sun gear 42 and the shaft 11 of motor part 10 is coaxial, the central part press-in shaft of the input sun gear 42
11.The first planetary gear 43 is engaged with above-mentioned input sun gear 42, and the first planetary gear 43 is nibbled with internal gear 48A
Close.Therefore, revolved round the sun by the rotation of shaft 11, the first planetary gear 43 around input sun gear 42, pass through the revolution, the first row
Star wheel frame 44 is coaxially rotated with shaft 11.
The second planetary gear 46, and are engaged with the intermediate sun gear 45 rotated integrally with the first planetary wheel carrier 44
Two planetary gears 46 are engaged with internal gear 48A.Therefore, the rotation of the intermediate sun gear 45 with the one of the first planetary wheel carrier 44 is passed through
Turn, the second planetary gear 46 revolves round the sun around intermediate sun gear 45, and by the revolution, the second planetary wheel carrier 47 and shaft 11 are coaxially
Rotation.Thereby, the rotation of shaft 11 is decelerated and is transferred to the output shaft 41 with the one of the first planetary wheel carrier 47.
In the state of planetary gears 40 is assembled in motor part 10, the first planetary gear unit 40A, which is assembled into, to be made
Multiple first planetary gears 43 contact with the slip bearing plane 22A of centering member 20 and make the first planetary gear 43 and input fixed star
Gear 42 engages.Also, the second planetary gear unit 40B, which is assembled into, makes the flat of the second planetary gear 46 and the first planetary wheel carrier 44
The front end face of smooth shape contacts and the second planetary gear 46 is engaged with intermediate sun gear 45.
In addition, gear housing 48 is shaped generally as cylindrical shape by hard synthetic resin material etc., in the gear housing 48
The rear end side of perisporium is provided with engaged part 48B, and engaged part 48B is located at the axisymmetric position of shaft 11.
Engaged part 48B is with being connected multiple holding sections 32 included by fixing component 30 accordingly in internal gear 48A
Mandrel is provided with multiple.Each engaged part 48B be for holding section 32 the recesses that are fitted together to of engaging protrusion 32A or connecting hole (according to
Illustrative example is connecting hole).By above-mentioned engaged part 48B, it is not necessary to, can be by turn over using the combination members such as screw or instrument
More mode carries out chimeric and realizes Simple assembled.
Also, gear housing 48 has the opening portion 48C coaxial with internal gear 48A in its front, and makes output shaft 41
Protruded from opening portion 48C.In retainer 41A of the peripheral part formed with annular groove shape of above-mentioned output shaft 41, in retainer 41A
Upper be fitted together to has ring 29.Above-mentioned ring 29 prevents gear housing 48 from being extracted forward relative to output shaft 41.
Next, to centering member 20, connection fixing component 30 and planetary gears 40 etc. are assembled in motor part
An example of 10 order is described in detail.
First, input sun gear 42 is fitted and fixed with the shaft 11 in motor part 10.
Then, make centering member 20 chimeric with the annular convex 12A1 outer circumferential surfaces of 12 front of motor shell.
Next, make the snap-latch surface 33 of connection fixing component 30 chimeric with the annular convex 22 of 20 front of centering member,
The eaves portion 31 for connecting 30 rear end of fixing component is fixedly welded on to the chamfered section 12B of 12 front end of motor shell.
Afterwards, such as by gear housing 48 it is inverted, makes the second planetary wheel carrier 47, the second planetary gear 46, the first planetary gear
Frame 44, the first planetary gear 43 sequentially enter the inside of the gear housing 48, finally, the input fixed star that will be protruded from motor part 10
Gear 42 is inserted into the center side of multiple first planetary gears 43.At this time, connect fixing component 30 to be inserted into gear housing 48, connection
32 elastic deformation of holding section of fixing component 30, and engage with the engaged part 48B of 48 perisporium of gear housing.Then, ring 29 is made
It is chimeric with the output shaft 41 protruded forward from gear housing 48.
Therefore, according to the gear motor 1 of said structure, if by centering member 20, connecting fixing component 30 and planet tooth
Wheel mechanism 40 grade is assembled in motor part 10 successively, then passes through above-mentioned centering member 20, connection fixing component 30 and planetary gear
The snap-fit relationship of mechanism 40, can accurately carry out between the shaft 11 of motor part 10 and the output shaft 41 of planetary gears 40
To the heart.
Also, due to being without using the structure of screw, energy in the connection of motor part 10 and planetary gears 40
The integrated structures such as threaded fastener are excluded, can realize small-sized and path.
Further, since the elasticity that the metal connection fixing component 30 being connected with motor shell 12 is passed through into holding section 32
Deform and engage with gear housing 48, therefore not only the connection operation is easy, moreover it is possible to keep the intensity of the coupling part higher.
Further, since rotating first planetary gear 43 is born by the slip bearing plane 22A of 20 front end of centering member
End face, therefore the supporting structure is simple, thereby can also realize small-sized path.
