Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Embodiment 1; A kind of Synchronous Transmission Equilibrator with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and shown in Figure 7, is characterized in that: comprise four synchronous rack shafts 1, driving gear 3, transmission shaft 5, tooth bar drive sprocket 6, guiding tooth bar connecting base 2 synchronously; Guiding tooth bar connecting base 2 is installed on the operate outside platform near Si Jiaochu; Rack shaft 1 end is connected through screw and guiding tooth bar connecting base 2 synchronously, is processed with linear gear rack 4 on the rack shaft 1 synchronously, and linear gear rack 4 is meshed with driving gear 3; Driving gear 3 is installed on the transmission shaft 5 and through key and is connected with transmission shaft 5; 5 of two transmission shafts interconnect through axle connecting sleeve 10, guarantee that the distance of transmitting torque is consistent, and transmission shaft 5 ends are provided with synchronous tooth bar drive sprocket 6 and are connected with transmission shaft through key; Interconnect through chain 12 between two synchronous tooth bar drive sprockets 6, guarantee the unanimity of the circumferential displacement of sprocket wheel.
Chain 12 between two synchronous tooth bar drive sprockets 6 is the mirror image symmetry each other.
The axle connecting sleeve 10 that two transmission shafts are 5 is the mirror image symmetry each other.
Rack shaft 1 is provided with linear bearing 7 guiding that are symmetrically distributed about driving gear 3 synchronously.
Be positioned at the driving gear both sides on the transmission shaft and be provided with bearing 8 and dottle pin 9.
More than constituted a kind of structure of the utility model.
The concrete workflow of the utility model is: any one jiao when receiving load when the operate outside platform; Corresponding with it synchronous rack shaft 1 can produce the action that moves up and down; Rack shaft 1 appended linear gear rack 4 is meshed with driving gear 3 in the process that moves up and down synchronously; Driving gear 3 is circumferentially rotated produce moment of torsion; Transmission shaft 5 is passed to another driving gear with moment of torsion through axle connecting sleeve 10, gear rotation reason and drive the linear gear rack that is meshed and move up and down synchronously, and corresponding synchronous rack shaft moves up and down thereupon; When transmission shaft 5 is passed to another driving gear with moment of torsion through axle connecting sleeve 10; Tooth bar drive sprocket 6 also rotates thereupon synchronously; Through chain 12 circumferential displacement synchronous is sent to another sprocket wheel, sprocket rotation produces moment of torsion, and drives the driving gear rotation through transmission shaft; In like manner guarantee the conformity that four toothed rack axles move up and down, thereby guaranteed the levelness of working platform.
The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the equivalence that all the present invention's shape, structure and principle are done changes, all should be covered by in the protection domain of the utility model.
The structure of tooth bar drive sprocket and axle connecting sleeve had both made the distance of transmitting torque consistent synchronously; Make driving mechanism basic identical again; Even because reasons such as load variations make component produce distortion and error, overall distortion also is the same with error, this has just guaranteed the precision of Synchronous Transmission; Make this Synchronous Transmission Equilibrator more reliable, precision can be controlled in the 0.5mm.
The utility model Synchronous Transmission balance quality guarantees easily; Its structure is very not complicated, and the general machine industry of the machining accuracy of each component is not difficult to reach, and the cost cost is lower; The length of chain, linear gear rack and axle connecting sleeve two ends transmission shaft can be confirmed with the need; The production flexibility is stronger, is mainly used in the balance that keeps heating plate in the car carpeting manufacturing automation production line, also can be used for keeping the balance of press table top.
