Description
Technical field
The utility model belongs to retarder field, and in particular to a kind of retarder.
Background technique
Harmonic speed reducer is made of three basic element of character, steel wheel, flexbile gear and wave producer composition.The work of the retarder
Process: it is usually that steel wheel is fixed, when wave producer rotates, forces flexbile gear to generate flexible deformation, make the tooth of flexbile gear and the tooth of steel wheel
Into meshing state, to realize transmission.
Retarder is driven using the harmonic speed reducer of traditional form in the prior art, is evenly distributed four output shafts
(as shown in Figure 1), because customers' place's bulk limits, and two output shafts of output that need to link, therefore a Novel speed-reducing need to be designed
Device is to adapt to new demand.
Existing Chinese patent document CN106246811A discloses a kind of harmonic speed reducer, main technical schemes are as follows: one
Kind harmonic speed reducer comprising: external gear end cap, the bearing plate being fixed on the external gear end cap and the bearing plate group
Assembly is closed and is partially protruded into the bearing (ball) cover in the external gear end cap, the roller bearing being fixed on the bearing (ball) cover, cam, consolidates
The external gear that is scheduled in the external gear end cap, the internal gear that connection is engaged with the external gear and it is located at the internal gear and cam
Between flexible bearing；Wherein, the internal gear is fixedly connected with bearing (ball) cover；The cam is mutually interconnected with the flexible bearing
It connects.It is different from the utility model.
Utility model content
The purpose of this utility model is to solve the above problems, and provides a kind of retarder, is solved using traditional form harmonic wave
The problem of retarder can not export universal driving shaft, can not arrange in taper cabin.
To achieve the above object, the utility model provides the following technical solutions:
A kind of retarder, including motor and retarder outer shell, be successively arranged above the motor worm couple and
Level-one spur gear pair, level-one spur gear pair side are equipped with second level spur gear pair, are equipped with three above the second level spur gear pair
Grade spur gear pair is equipped with potentiometer far from the other side of level-one spur gear pair in the second level spur gear pair, on the potentiometer
Side is equipped with output shaft, and the output shaft runs through three-level spur gear pair center and outer shell, the level-one spur gear pair centre bit
Bearing is installed；The motor drives level-one spur gear pair, imparts power to output shaft through three-level spur gear pair.
Further, this retarder speed ratio is 88, rated output torque 1Nm, and absorbing impact power is 10000g.This is practical
Novel beneficial effect is:
The utility model retarder is made of level Four gear pair, completes transmission speed ratio using worm couple and spur gear pair
With the conversion of output position, reach the operability of torque and assembly required by retarder.It solves and uses traditional form harmonic wave
The problem of retarder can not export universal driving shaft, can not arrange in taper cabin, and impact resistance is strong.
Detailed description of the invention

Specific embodiment
A kind of retarder as in Figure 2-4, including motor 1 and retarder outer shell 9,1 top of motor is successively
Equipped with worm couple 2 and level-one spur gear pair 3,3 side of level-one spur gear pair be equipped with second level spur gear pair 6, described two
It is equipped with three-level spur gear pair 7 above grade spur gear pair 6, in the other side of the second level spur gear pair 6 far from level-one spur gear pair 3
Equipped with potentiometer 5, output shaft 4 is equipped with above the potentiometer 5, the output shaft 4 runs through 7 center of three-level spur gear pair and outer layer
Shell 9,3 center of level-one spur gear pair are equipped with bearing 8；The motor 1 drives level-one spur gear pair 3, straight through three-level
Gear pair 7 imparts power to output shaft 4.Further, this retarder speed ratio is 88, rated output torque 1Nm, bears punching
Hitting power is 10000g.
The working principle of the utility model are as follows:
The actuation mechanism of pose adjustment, is arranged in aircraft when the utility model is for aircraft flights such as unmanned planes
Tail portion.When aircraft flight, by controlling the deflection angle of tail portion rudder piece, the posture of aircraft is adjusted, such as azimuth, pitching
Angle, roll angle.Rudder piece is connected with the utility model output shaft 4, and motor 1 drives retarder, and the pivot angle of control flaps piece reaches control
The posture purpose of aircraft.
The course of work is that control system sends to motor 1 and orders, 1 outputting torsion of motor, after retarder strength amplification
The required swing angle of output completes the closed loop of system from potentiometer 5 to the electric signal of control system feedback institute's swing angle
Control.
The utility model retarder is made of level Four gear pair, completes transmission speed using worm couple 2 and spur gear pair
Than the conversion with output position, reach the operability of torque and assembly required by retarder.It solves humorous using traditional form
The problem of wave retarder can not export universal driving shaft, can not arrange in taper cabin, and impact resistance is strong.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
