Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with example.
Embodiment 1:
One embodiment of the utility model is a kind of forward backward rotation force-increasing mechanism of anti-reverse impact, the mechanism structure
At a relatively independent functional module, it is particularly suitable in the lower-powered robot of industrial robot especially motor driven
Middle use.
As shown in Figure 1, 2, the present embodiment is mainly by chain 1, bracket 2, sprocket shaft 3, sprocket wheel 4, the first feed screw nut 5,
One screw rod 6, driving motor 7, driving gear 8, the first driven gear 9, idle pulley 10, the second feed screw nut 11, the second screw rod 12 and
Second driven gear 13 composition.
Sprocket shaft 3 is used as output shaft, outwardly provides driving, is mounted on the upper end of bracket 2, and can be in the upper of bracket 2
End rotation.Sprocket wheel 4 is connect with sprocket shaft 3, and chain 1 can be rotated on sprocket wheel 4 by the movement of chain 1 with movable sprocket 4,
And then sprocket shaft 3 is driven to rotate.
First screw rod 6 is connect with the second screw rod 12 with bracket 2, and 2 lower end of bracket is stretched out in the end of two screw rods, and first is driven
Gear 9 and the second driven gear 13 are separately fixed at the end of two screw rods.The central axis of first screw rod 6 and the second screw rod 12
It is parallel and coplanar with the vertical tangent line of sprocket wheel 4.First feed screw nut 5 and the second feed screw nut 11 are separately positioned on the first screw rod 6
On the second screw rod 12, the both ends of chain 1 are connect with the first feed screw nut 5 with the second feed screw nut 11 respectively.Therefore, silk is rotated
Bar may make the nut matched to move in a straight line, so that chain 1 be driven to move.Two screw rods are adjusted simultaneously, can be made
Chain 1 is exceptionally straight to be in tensioned state.
Driving motor 7 is mounted on the lower end of bracket 2, and driving gear 8 is mounted in the drive shaft of driving motor 7.It is lazy
Wheel 10 is mounted on the lower end of bracket 2 in the form of revolute pair.Drive gear 8, the first driven gear 9, idle pulley 10 and second driven
The central axis of gear 13 is parallel to each other.
When driving motor 7 works, driving gear 8 will be rotated with it, while drive first be engaged with respectively driven
Gear 9 and idle pulley 10 rotate, and idle pulley 10 drives the second driven gear 13 being engaged with to rotate again.Make since idle pulley 10 commutates
With the first driven gear 9 will be reversely rotated with the second driven gear 13, to drive the first screw rod 6 with the second screw rod 12 with phase
Anti- rotation direction rotation.The first feed screw nut 5 will run with the second feed screw nut 11 in a manner of one on the other at this time, to drive
Chain 1 acts, and then rotates with movable sprocket 4 or even sprocket shaft 3.If driving motor 7 inverts, then respective sprocket axis 3 also will be reversed
Revolution.
By described above it is found that the impact resistance of the mechanism, screw rod can be enhanced due to by the way of chain drive
Lead it is smaller, the effect similar with torque increase of slowing down can be played.Therefore the forward backward rotation force-increasing mechanism of the structure, anti-impact
Hitting property is stronger, can reduce existing impact force when the revolution unexpected counter motion of force-increasing mechanism, and the use of feed screw nut's structure makes
Deceleration torque increase can be played the role of by obtaining mechanism, and structure is simple, have stronger stability.Structure is with relatively independent module
The mode of change provides, and is also convenient for the maintenance replacement in later period.
