Wuhan Grain Industry College.'s journal " 2 phases in 1988 are introduced a kind of patrilineal line of descent with only one son in each generation movable sprocket intermittent motion mechanism, though this mechanism has improved above-mentioned drawback effectively, its follower is stirred pin and is adopted cantilever beam structure, and rigidity is relatively poor, be not suitable for bearing big load, robust motion is relatively poor.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of long period chain-driven intermittent motion mechanism, takes up room greatly to solve existing apparatus, can't bear big load, the problem that robust motion is relatively poor.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of long period chain-driven intermittent motion mechanism is provided, by input shaft, organize a sprocket wheel, organize a chain, axle, organize two sprocket wheels, sprocket wheel is formed, and described group one sprocket wheel flat key is fixed in the input shaft two ends and is connected with group one chain, and described group one chain is connected in organizes two sprocket wheels, described group two sprocket wheel ball bearing is connected in axle, and described sprocket wheel is fixed in axle in the inboard middle position of group two sprocket wheels flat key.
Described group one sprocket wheel is made up of two sprocket wheels, and described group two sprocket wheel is made up of two sprocket wheels, and described group one chain is made up of two chains.
Described roller is connected in group one chain in two ends, the inboard middle position of group one chain.
Beneficial effect
The utility model innovative point is to use double-stranded wheel drive structure, and follower is stirred the roller structure form that pin adopts two supports, realizes intermittent movement, good rigidly, and bearing load is big.Improve even eliminated the shortcoming of above-mentioned patrilineal line of descent with only one son in each generation movable sprocket intermittent motion mechanism to a great extent.Be particularly suitable in long and narrow space, needing to realize the situation of intermittent movement.The utlity model has following advantage:
Driving sprocket wheel can adopt the two strands wheel of standard, need not special processing;
Drive chain can adopt three row's chains of standard according to gap transmission cycle request, changes a social system use;
Convenient processing and manufacture is made, maintenance cost is cheap.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
A kind of long period chain-driven intermittent motion mechanism one, by input shaft 1, organize a sprocket wheel 2, organize a chain 3, axle 6, organize two sprocket wheels 8, sprocket wheel 9 is formed, and organizes a sprocket wheel 2 flat keys and is fixed in input shaft both sides, 1 stage casing and is connected with group one chain 3, organizes a chain 3 and is connected in and organizes two sprocket wheels 8, organize two sprocket wheels, 8 ball bearings and be connected in axle both sides, 6 stage casing, sprocket wheel 9 is fixed in axle 6 in group two sprocket wheels 8 inboard middle position flat keys.Organize a sprocket wheel 2 and form, organize two sprocket wheels 8 and form, organize a chain 3 and form by two chains by two sprocket wheels by two sprocket wheels.Roller 4 is connected in group one chain 3 in group two ends, one chain, 3 inboard middle position.
Input shaft 1 is by motor driving.Two flat key 7 drives of installing on the input shaft 1 are organized a sprocket wheel 2 and are rotated.Organize 8 rotations of two sprocket wheels by organizing a chain 3 gearing drives.Organize two sprocket wheels 8 (design in advance) under certain damping function, axle 6 can not rotate with group two sprocket wheels 8.Because organize the motion of a chain 3, the roller 4 of two chains of connection is movement therewith also.When roller 4 moves to the A position,, and then drive sprocket wheel 9 rotations with the gear teeth of engaging-in sprocket wheel 9.By the effect of flat key 7, sprocket wheel 9 drove axle 6 and together rotated this moment, when last root roller 4 after opposite side breaks away from sprocket wheel 9, under the effect of the damping of design in advance, sprocket wheel 9 and axle 6 stop operating, until roller 4 once more by the engaging-in sprocket wheel 9 in A position.
