The function of the input side cover of the shell 28 of speed reducer 11.Also, in present embodiment, the outer peripheral surface 14A of the motor connector 14
Outside diameter d 14A be formed larger than the most outer diameter d12 of motor 12.
Thereby, it is possible to make entire motor 12 by the inner peripheral surface 16B of pedestal 16 (i.e. pedestal 16 with 14 phase of motor connector
Pair opening portion) and be located in than opening portion 16B in the axial direction more by the side opposite with speed reducer.
Then, the effect of the deceleration device 10 is illustrated.
Firstly, the effect of the drive system of speed reducer 11 is briefly described.
If the motor drive shaft 15 of motor 12 rotates, the input shaft 18 of the motor drive shaft 15 is linked to via friction grip 19
It rotates integrally.If eccentric body 20 is rotated by the rotation of input shaft 18, the outer of the eccentric body 20 is assembled in via roller 22
The external gear 24 in week is swung.Due to external gear 24 and 26 internal messing of internal gear, generated by the swing and internal gear
The phenomenon that 26 position of engagement successively deviates.
The every rotation of input shaft 18 1 time as a result, the phase of external gear 24 is only inclined relative to the internal gear 26 in stationary state
It moves and teeth number difference a considerable amount (1 tooth amount) and progress rotation.The rotation ingredient is transmitted to the pin member 30 through the external gear 24,
Make the 1st wheel carrier 32, the rotation of the 2nd wheel carrier 34 that support pin member 30.By the rotation of the 1st wheel carrier 32, the 2nd wheel carrier 34, make via
Screw hole 32A is linked to the rotation of the rotating circular disks 42 such as the charging tray of the 1st wheel carrier 32.In addition, the swing ingredient of external gear 24 is by pin member
Gap between 30 and through hole 24A absorbs.
Here, in deceleration device 10 involved in present embodiment, the flange part bolt insertion hole of speed reducer flange part 50
The internal diameter D16B for forming pitch circle P71 and being less than the inner peripheral surface 16B of pedestal 16 of 50S.Therefore, it is impossible to directly with the speed reducer flange part
Speed reducer 11 is mounted on pedestal 16 by 50 flange part bolt insertion hole 50S.In the past, in this case, it remanufactured
Speed reducer flange part is formed as into bigger shell to cope with.But it if increasing the speed reducer flange part of shell, must increase
It should be fixed on the motor connector of the axial side of the speed reducer flange part, therefore cost can be greatly increased.
But structure according to the present embodiment, pedestal 16 can be installed on deceleration via pedestal installation component 60
The speed reducer flange part 50 of machine 11.About the connection of motor connector 14, without changing the flange part spiral shell of speed reducer flange part 50
Bolt insertion hole 50S and can continue to using, therefore without change motor connector 14 and can continue to using.As a result, with
Past " mode for correspondingly changing both speed reducer flange part and motor connector according to object Part " is compared, and is realized into
This is greatly reduced.
In particular, in present embodiment, the shell 28 of speed reducer 11 doubles as the internal tooth wheel body 26A of internal gear 26, and
The inner circumferential side of the shell 28 is formed with the cotter way 26C for rotatably freely retaining pin 26B.Therefore, the manufacturing cost of shell 28
It is especially high.Accordingly, with respect to various object Parts, without remanufacturing the shell with the speed reducer 11 of internal gear
28, this effect for reducing cost is especially big.
In addition, the outside diameter d 14A of (constituting the latch portion latched with pedestal 16) outer peripheral surface 14A of the motor connector 14
Greater than the most outer diameter d12 of motor 12.Therefore, entire motor 12 can be made to pass through the opening portion 16B of pedestal 16, and be located in than this
Opening portion 16B more leans on the position with speed reducer opposite side.Thereby, it is possible to reduce deceleration device 10 from the size outstanding of pedestal 16
L1 (Fig. 1).
It, can be to be equipped with the state of motor 12, from pedestal installation with 60 side of component (with horse also, when being safeguarded etc.
Up to opposite side: the side opposite with object Part) deceleration device 10 is dismantled, therefore operability is very good.Also, due to
Motor connector 14, pedestal installation component 60 and pedestal 16 be configured to by from 60 side of pedestal installation component (with motor
Opposite side: the side opposite with object Part) insert the 1st binder bolt 71, the 2nd binder bolt 73 and be interconnected,
Therefore it the disassembly operation and retightens operation and can be carried out from pedestal installation with 60 side of component, on this point, it is operational
Well.
The variation of above embodiment is shown in Fig. 3 (A) and Fig. 3 (b).
In Fig. 3 (A), pedestal installation is more leaning on diameter than speed reducer flange part 50 with component (object Part installation component) 80
Also there is the mounting portion 80C for installation pedestal 16 outward.Also, pedestal installation with component 80 with speed reducer flange part 50
The identical position of radial position on also have and be fixed on the fixed part 80E of speed reducer flange part 50.But the example of the Fig. 3 (A)
In, the radial position of (when from end on observation) mounting portion 80C and fixed part 80E is to separate.That is, when from end on observation, "
In pedestal installation component 80, which installs the part (i.e. mounting portion 80C) contacted with component 80 with pedestal 16 " and " in base
In seat installation component 80, which installs the part (i.e. fixed part 80E) contacted with component 80 with speed reducer flange part 50 "
Radial position is separated.
Specifically, the pedestal installation section of component 80 is in T-shaped, and pedestal installation component 80 have with subtract
The adjacent mode of fast machine flange part 50 configures and the annulus 80R equipped with mounting portion 80C and fixed part 80E and from the annulus
The surface of the motor-side of 80R spacer portion 80K outstanding.Spacer portion 80K configures the outer peripheral surface 50C in speed reducer flange part 50
Between (and outer peripheral surface 14A of motor connector 14) and the inner peripheral surface 16B of pedestal 16.The inner peripheral surface 80K1 structure of spacer portion 80K

W80K can be aligned the formation pitch circle and base of the mounting portion bolt insertion hole 80S2 of the mounting portion 80C of pedestal installation component 80
The formation pitch circle of the screw hole 16T of seat 16.That is, as shown in the structural example of the Fig. 3 (A), even if in the inner peripheral surface 16B of pedestal 16
Diameter D16B is greater than the outside diameter d 50C of the outer peripheral surface 50C of speed reducer flange part 50, and (or the outer peripheral surface 14A's of motor connector 14 is outer
Diameter) in the case where, above-mentioned feelings can be coped with by only adjusting the thickness W80K of spacer portion 80K of pedestal installation component 80
Condition.
In addition, in the pedestal installation component 80 of the Fig. 3 (A), the axial length L 80E and mounting portion of fixed part 80E
The axial length L 80C of 80C is set as identical (L80E=L80C).But it is also possible to by the axial length L 80E of fixed part 80E
It is set as different with the axial length L 80C of mounting portion 80C.The axial other side of speed reducer flange part 50 can be also absorbed as a result,
On the axial position of 2nd face 50B and the axial direction of pedestal 16 and the deviation of motor opposite side end face 16G is (alternatively, can be energetically
