The present invention is further elaborated with reference to the accompanying drawing.
A kind of submissive constant moment of force shaft coupling, the first and second half-shell 11,12 including secure fit, in the first half-shell 11
Portion is fixedly connected with driving shaft, is rotatably assorted in the middle part of the second half-shell 12 by bearing and the composition of driven shaft sleeve 20, described first,
Submissive constant moment of force mechanism is provided between two half-shells 11,12, submissive constant moment of force mechanism includes 30 He of active bracket of flexible connection
Driven carriage 40, active bracket 30 are fixed in first half-shell 11, and the inner end of driven carriage 40 and driven shaft sleeve 20 is fixed to be connected
It connects.The present invention in coupling shell body by being arranged submissive constant moment of force mechanism, using between active bracket 30 and driven carriage 40
Flexible connection realize that the power between driving shaft and driven shaft transmits, more traditional positive coupling or flexible coupling and
Speech, can not only damping, buffering, additionally it is possible to transmit biggish torque, effect is good, applied widely.By the second half-shell 12 with it is driven
Shaft sleeve 20 is provided separately, then the rotation connection of the two is realized by bearing, so that processing and assembling more convenient.Specifically,
Active bracket 30 is fixedly connected by first half-shell 11 with driving shaft, and driven carriage 40 is solid by driven shaft sleeve 20 and driven shaft
Fixed connection, when work, driving shaft rotation drives active bracket 30 to rotate synchronously, the rotation of active bracket 30 cause driven carriage 40 with
Flexible deformation is generated between active bracket 30 and driven carriage 40 is driven to rotate with it, so that driven shaft be driven to rotate, is existed in this way
Vice division chief is moved during movement transmitting will not generate friction, and kinematic accuracy is high.Preferably, submissive constant moment of force mechanism selects spring
Steel material, the first and second half-shell 11,12 select common structural steel.
Further, the active bracket 30 generally from cradling piece 31 two-by-two with the frame-like structure that constitutes, bracket
The middle part of bar 31 has inwardly protruded out overhanging bar 32, the driven carriage 40 generally plate, the projecting end of overhanging bar 32 with it is driven
Bracket 40 is fixedly connected.When it is implemented, overhanging bar 32 arranges that one end of overhanging bar 32 is fixed on bracket perpendicular to cradling piece 31
On bar 31, the other end is fixed on driven carriage 40, even if by overhanging bar 32 come real between active bracket 30 and driven carriage 40
Now it is flexibly connected.When driving shaft rotation, the rotation of active bracket 30 makes 32 stress of overhanging bar, in active bracket 30 and driven carriage
Flexible deformation is generated between 40, to realize the transmitting of power.
Further, the cradling piece 31 includes being located in the middle spill rod piece 311 and being connected to 311 both ends of spill rod piece
Straight-bar 312, the rod end of straight-bar 312 is fixedly connected in adjacent two stands bar 31, the fixing end and spill rod piece of overhanging bar 32

It stretches, has greatly reinforced the flexibility of overhanging bar 32, so that more compliant in the transmitting of power.
Further preferred embodiment is that the cradling piece 31 has the entire length of three and three cradling pieces 31 identical.
By 30 whole design of active bracket at equilateral triangle, increases the stability of active bracket 30 using triangular structure, can make
The transmitting for obtaining power is more stable, accurate, effectively avoids influence caused by the unstable transmitting on power because of active bracket 30.
Preferably, the entire length that the overhanging bar 32 is correspondingly arranged on three and three overhanging bars 32 is identical.By three
Overhanging bar 32 is arranged to identical length, ensures that the center of driven carriage 40 to the distance one of each cradling piece 31 in this way
It causes, so that power be allow uniformly to be transmitted on driven carriage 40 from active bracket 30.
Further, the projecting end of the overhanging bar 32 is provided with threaded hole 321, and corresponding position is set on driven carriage 40
It is equipped with connecting hole 41, the inner end of driven shaft sleeve 20 is provided with stepped hole 21, connects screw bolt passes stepped hole 21, threaded hole
321, driven shaft sleeve 20, overhanging bar 32 and driven carriage 40 are connected to one by connecting hole 41.When it is implemented, protecting
Stepped hole 21, threaded hole 321 and 41 same core of connecting hole arrangement are demonstrate,proved, then three is connected to one by connection bolt, from
And generation torque in motion process is avoided to cause kinetic energy rejection.
Further, the connecting pin of adjacent two stands bar 31 offers mounting hole 313 on the active bracket 30, and the first half
It is correspondingly arranged on fixation hole 111 on shell 11, fixing bolt passes through mounting hole 313, fixation hole 111 for active bracket 30 and the first half
Shell 11 is fixedly connected.Active bracket 30 is affixed directly in first half-shell 11, such active bracket 30 is just linked as with driving shaft
One, not will cause kinetic energy rejection during the motion.
Further, it is bolted to connection between the first half-shell 11 and the second half-shell 12.When it is implemented, the
The connecting hole being arranged in one half-shell 11 and the second half-shell 12 is counterbore, can guarantee to install rear bolt head and nut not in this way
