Sprocket wheel 53 and the second fixed conveyor sprocket wheel 222 are in the same end face.
For with movable sprocket 50, it is mounted on movable sprocket shaft with movable sprocket 50（It is not shown in figure）On, with movable sprocket
Shaft passes through with movable sprocket shaft bearing（It is not shown in figure）On driving shaft fixed block 103.Can be with movable sprocket 50
By pin key be fixed to in movable sprocket shaft, can also be by cut, forge etc. processing technologys will with movable sprocket 25 with
Movable sprocket shaft is integrally formed to be processed.In the present embodiment, company is fixed using pin key with movable sprocket shaft with movable sprocket 25
The mode connect is connected.With movable sprocket 51, with movable sprocket 52 and with movable sprocket 53 installation similarly.
In the first fixation chain 61 that is arranged right below of the first fixed conveyor sprocket wheel 221, the first fixed conveyor sprocket wheel 222
It is arranged right below the second fixation chain 62.First, which fixes chain 61 and second, fixes the walking road that chain 62 is mounted on transmission mechanism
On diameter.In the present embodiment, the first fixation chain 61 and second fixes the both sides that chain 62 is separately mounted to track.In operation field
Track length is usually limited, therefore is equipped with adjustable fixing device at the both ends of track（It is not shown in figure）, first fixes
Chain 61 and second is fixed chain 62 and is then mounted in the fixing device at track both ends.First fixed chain wheels 61 with movable sprocket
50, with movable sprocket 51, the first fixed conveyor sprocket wheel 221 fit system as shown in Figure 1, first fix chain 61 with movable sprocket
50 and with movable sprocket 51 inside gear teeth meshing, first fixes the wheel of the first half of chain 61 and the first fixed conveyor sprocket wheel 221
Tooth engagement.The fixing device for fixing 61 both ends of chain by adjusting first can adjust the fixation of the first fixation chain 61 and first
Drive sprocket 221, with movable sprocket 50 and with movable sprocket 51 engage elasticity.Second fix chain 62 with movable sprocket 52, with
Movable sprocket 53, the fit system of the second fixed conveyor sprocket wheel 222 are same.
It can be seen that when motor 30 drives drive sprocket 311 to rotate, drive sprocket 311 is driven driven by chain 32
Sprocket wheel 21 rotates, and driven sprocket 21 drives the first fixed conveyor sprocket wheel 221 and the second fixed conveyor sprocket wheel by active rotating shaft 20
222 rotation, the first fixed conveyor sprocket wheel 221 by with first fixation chain 61 engage, the second fixed conveyor sprocket wheel 222 by with
Second, which fixes chain 62, engages, to drive transmission mechanism to carry out operation transport on rail.The movement of idler wheel is by being actively changed to
It is driven, be conducive to avoid idler wheel the phenomenon that having skidded on rail.Servo motor and the power that helical speed reduction gear forms are defeated
Go out device, power output is stablized accurately, keeps idler wheel mechanism stable movement accurate, and idler wheel mechanism is avoided to influence production because unstable
Operation.
When the heavy burden of idler wheel mechanism is in different size, the detent torque size needed for drive sprocket 311 is then different.For
Reduce the original output torque of driving device, saves energy consumption, while keeping the motion stabilization of idler wheel mechanism, it can be by changing the
One fixes the packet between chain 61 and the first fixed conveyor sprocket wheel 221, second fixation chain 62 and the second fixed conveyor sprocket wheel 222
Angle is covered to realize above-mentioned purpose.Wrap angle refer to two point of contacts being formed between flexible structure and driving wheel in transmission mechanism with
The center of circle of driving wheel is formed by the angle between two lines.In the present embodiment, fixes chain 61 and first with first and fix
For drive sprocket 221, flexible structure is the first fixation chain 61, and driving wheel is the first fixed conveyor sprocket wheel 221.
In the present embodiment, the structure of the first fixed conveyor sprocket wheel 221 is identical as the structure of the second fixed conveyor sprocket wheel 222,
That is the gear parameters all same such as reference diameter, number of teeth.Equally, each is also identical with movable sprocket.With the reference circle of movable sprocket
Diameter is then less than the reference diameter of the first fixed conveyor sprocket wheel 221, is passed because the first fixed conveyor sprocket wheel 221 and second is fixed
Movable sprocket 222 is identical, so the reference circle for being also similarly less than the second fixed conveyor sprocket wheel 222 with the reference diameter of movable sprocket is straight
Diameter.In this way, the linear velocity and angular speed of the first fixed conveyor sprocket wheel 221 and the second fixed conveyor sprocket wheel 222 are equal, the
Linear velocity and angular speed of the one fixed conveyor sprocket wheel 221 with the second fixed conveyor sprocket wheel 222 on the fixation chain being meshed
It is equal, larger driving error will not occur because of linear velocity, angular speed difference between each sprocket wheel.
By adjusting with the height or size of movable sprocket, the cladding between fixed conveyor sprocket wheel and fixed chain can adjust
Angle size.
By taking the first fixed conveyor sprocket wheel 221 and first fixes chain 61 as an example, increase the first fixed conveyor sprocket wheel 221 and the
One fixes the wrap angle of chain 61, and first, which fixes chain 61, can generate transmission mechanism the pulling force of bigger.Increase first and fixes biography
Movable sprocket 221 and first fixes the fixing device that the wrap angle of chain 61 can fix 61 both ends of chain by adjusting first, and will
Setting is moved down with movable sprocket 40 and with movable sprocket 41 or is increased with movable sprocket 40 and is realized with the size of movable sprocket 41.Work as biography
When motivation structure is mainly used for load-carrying larger operating mode place, no need to increase the output torques of speed reducer 31 so that transmission mechanism is moved
Operation, transmission mechanism can also carry out the load transportation operation of bigger, while keep the stability of transmission mechanism.
It is opposite, when transmission mechanism is mainly used for the smaller operating mode place of load-carrying, 61 liang of chain is fixed by adjusting first
The fixing device at end, and setting will be moved up with movable sprocket 40 and with movable sprocket 41 or reduced with movable sprocket 40 and with movable sprocket 41
Size fix the wrap angle of chain 61 reducing the first fixed conveyor sprocket wheel 221 and first and improve efficiency, save energy consumption.
The above is only the preferred embodiment of the present invention, is not intended to limit the invention.In base described above
On plinth, the utility model can also make other various forms of variations or improvement, such as by fixed conveyor sprocket wheel and fixation
Mutual cooperation of the intermeshing fit system equivalent replacement of chain between transmission gear and stationary rack, increases the number of idler wheel
Amount etc..Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all include
It is within the protection scope of the utility model.
