Embodiment is specifically described
It elaborates with reference to the accompanying drawing to embodiment of the present invention.
As shown in Figure 1, be decelerating motor example of the invention, the running part of decelerating motor include motor output shaft 16,
Primary speed-down unit (Fig. 2), double reduction unit (Fig. 3) and output shaft 33.The cooperation of bearing 18 and primary speed-down unit, bearing
31 and output shaft cooperation, ensure that the axially position of entire running part and circumferentially positioned, prevent interstructural relative motion.
Motor output shaft 16 and first order deceleration unit figure (2) are connected by key, and output shaft 33 and second level deceleration unit (Fig. 3) pass through
Key 27 connects, and carries out axially position, first order deceleration unit (Fig. 2) and second level deceleration unit (Fig. 3) with circlip 26
It is connected by key 21, and carries out axially position with circlip 20.
First order deceleration unit includes centre wheel 8, outer gear ring 2, coplanar gear ring 10 and planet carrier.Centre wheel 8 and coplanar tooth
The interior tooth engagement of circle 10, meanwhile, 2 internal messing of external tooth and outer gear ring of coplanar gear ring 10.Planet carrier includes 11 He of left side planet carrier
Right side planet carrier 8, two sides planet carrier have jagged boss and jagged concave station in same position respectively, and boss concave station exists
It is circumferentially distributed on planet carrier, while being equipped with screw hole on boss and concave station, when being connected two sides planet carrier by screw 20
When, boss and the concave station intermeshing of two sides planet carrier become a whole planet carrier.Planet carrier 11 is fixed on by bearing 18
On end cap 13, planet carrier 8 keeps circumferential positioning by bearing 25.Self-control bearing 23 is located in left side planet carrier and coplanar gear ring
Between, relatively rotate planet carrier and coplanar gear ring, self-control bearing 24 is located among right side planet carrier and coplanar gear ring, in this way
Entire planet carrier can just be relatively rotated with coplanar gear ring.During exercise, planet carrier is as input, due to structure bias, planet
Frame drives coplanar gear ring 2 to move, and coplanar gear ring 10 and outer gear ring 2 and centre wheel 8 engage simultaneously, and such first order deceleration unit is just
There is the movement determined, planet carrier 11 and planet carrier 8 are used as torque input link, and centre wheel 8 is used as torque output link.
Second level deceleration unit includes centre wheel 4, outer gear ring 2, coplanar gear ring 5 and planet carrier.Planet carrier includes left row
Carrier 7 and right side planet carrier 3, two sides planet carrier has jagged boss and jagged concave station in same position respectively, convex
The shape and position of platform and concave station are identical as planet carrier 11,8, when two sides planet carrier is connected by screw 28, two sides planet
The boss and concave station of frame are intermeshed, and become a whole planet carrier.Planet carrier 7 is connected by bearing 25 and primary speed-down unit
It connects, guarantee is circumferentially positioned, and planet carrier 3 is guaranteed circumferentially positioned by bearing 30 and the connection of output shaft 33.Make bearing 6 and self-control axis by oneself
It is identical as the primary speed-down unit self-control position of bearing 23,24 in the position of double reduction unit to hold 29.Therefore, double reduction list
Member and primary speed-down unit are all that the gear transmission unit with three degree of freedom, planet carrier 7 and a planet carrier 3 are defeated as torque
Enter component, centre wheel 4 is used as torque output link.
Output shaft 33 is connect by key 28 and circlip 26 with double reduction unit, and the output of double reduction unit is turned round
Square is exported to the outside of entire decelerating motor.
Cabinet of the invention is made of five parts.It mainly include electric machine casing 15, adjustment flange 14, speed reducer rear end cap
12, reducer shell 2 and speed reducer drive end bearing bracket 1.15 right-hand end of electric machine casing has covered tapped through hole, adjusts flange 14 and subtracts
Also there is tapped through hole in identical position on fast machine rear end cap 12, can by hexagon-headed bolt and nut by speed reducer rear end cap 12,
Adjustment flange 14 and electric machine casing 15 connect.There are threaded hole, the forward and backward end cap of retarder (1,12) in 2 two sides of reducer shell)
There is counterbore in corresponding position, the forward and backward end cap of speed reducer (1,12) and reducer shell 2 can be connected by screw.Box house
Using oil lubrication, oil sealing 17 and 32 guarantees box house closing, prevents oily leakage.
The sequence of motion of present example are as follows: input link of the output shaft of motor as decelerating motor subtracts with the first order
The planet carrier of fast unit is connected, and as the input link of retarder module, the center gear teeth of first order deceleration unit are output structure
Part, while it being connected to the planet carrier of the second level deceleration unit input link of second level deceleration unit, the second level is slowed down single
The centre wheel of member is connected with output shaft, and output shaft is entire decelerating motor output link, and outer gear ring is fixing component.Realize electricity
Machine is integrated with retarder, and has achieved the purpose that decelerating motor increases square reduction of speed.
