Connect, the nut in mobile push pedal 504 is engaged with screw mandrel, and nut forms feed screw nut pair with screw mandrel, is made by the rotation of screw mandrel
Push pedal must be moved to be moved axially along screw mandrel.Mobile push pedal 504 is formed with polished rod 505 and is slidably connected.Being rotated in screw mandrel makes piston
When forming extruding to the material in material chamber (pressure on piston gradually increases), mobile push pedal in the presence of screw mandrel also with piston
Motion in the same direction, because mobile push pedal is also supported on polished rod, it is ensured that the linearity of screw mandrel.The dual input decelerator includes case
Body 100, the first power source, the first input shaft 401, the second power source, the second input shaft 402, first gear reducing gear, second
Gear reduction, the 3rd gear reduction, the first output shaft 301 and the second output shaft 302.Generally, the first power source is adopted
With the power set of low speed, such as servomotor；Second power source uses the power set of high speed, such as three phase electric machine.
Wherein, first input shaft 401 is rotatably mounted on casing 100, the output end of first power source
It is connected with first input shaft 401, drives the first input shaft 401 to rotate using the first power source.
Second input shaft 402 is rotatably mounted on casing, the output end of second power source and described
Two input shafts 402 are connected, and drive the second input shaft 402 to rotate using the second power source.
First input shaft 401 is connected by first gear reducing gear with the second input shaft 402.By electromagnetic clutch
Device make first gear reducing gear and the second input shaft 402 can clutch connection, make driving torque from the first input shaft 401 to second
The single-direction transmission of input shaft 402.Specifically, the first power source runs during the decelerator as in output dynamic regime, electricity
Magnet clutch is in engagement state, and the power that the first power source is exported is successively through the first input shaft 401, first gear reductor
Structure and be delivered on the second input shaft 402, then to be ultimately transferred to the first output shaft 301 and second via the second input shaft 402 defeated
Shaft 302；Second power source runs during the decelerator as in output dynamic regime, and electromagnetic clutch is in and separates shape
State, the power that the second power source is exported only is transmitted to the first output shaft 301 and the second output shaft 302.In the present embodiment,
One gear reduction preferably uses three-stage gear reduction mechanism, and it includes first gear 1, second gear 2, the 3rd gear 3, the
Four gears 4, the 5th gear 5, the 6th gear 6, first rotating shaft and the second rotating shaft.Certainly, first gear reducing gear can also be adopted

Gear 6 radial rotating and axially slidably can be arranged on the second input shaft 402, usual 6th gear and the second input shaft 402
Gap coordinates, and the 6th gear 6 is meshed with the 5th gear 5；The gear 6 of driven member 201 and the 6th of electromagnetic clutch 200 is consolidated
Fixed connection, the driving link 202 of electromagnetic clutch 200 is mutually fixedly connected with the second input shaft 402.When electromagnetic clutch is engaged,
6th gear is connected with the second input shaft 402, and the 6th the second input shaft of gear driven 402 in rotary state is rotated,
So as to moment of torsion be transmitted to the first output shaft 301 and the second output shaft 302；When electromagnetic clutch is separated, the second input shaft 402
Freely rotated relative to the 6th gear so that the torque of the second input shaft 402 passes only to the first output shaft 301 and the second output
Axle 302.As can be seen here, by the structure, the second power source as in output dynamic regime to run the decelerator when, energy
The output shaft of the first power source is enough avoided to be rotated by speedup, to ensure the service life of the first power source；Furthermore, first gear subtracts
Gear in fast mechanism also will not be by speedup so that the decelerator operating noise is relatively small.It is noted that electromagnetic clutch
Device can also be assemblied in other positions, so that first gear reducing gear and the second input shaft 402 can clutch connections；Such as electricity
What magnet clutch, the second rotating shaft and the 4th gear were formed uses cooperatively, or electromagnetic clutch, first rotating shaft and the 3rd gear
Formed with the use of etc..Generally, the first power source and the second power source are located on the two relative side of casing.
