Abstract
The invention discloses a gear transmission structure which comprises a machine base and a rotating shaft. A connecting rod is arranged at one end of the rotating shaft. A first transmission gear is arranged at one end of the rotating shaft in a sleeving manner, and a second transmission gear and a third transmission gear are arranged at the other end of the rotating shaft. The second transmission gear is provided with a through hole with the diameter the same as that of the connecting rod. The second transmission gear is arranged on the connecting rod in a sleeving manner through the through hole. A protruding block is arranged on the third transmission gear, and a limiting cavity with the diameter the same as that of the connecting rod is formed in the protruding block. The third transmission gear is connected with the end face of the connecting rod through the limiting cavity. According to the gear transmission structure, external interference can be reduced, transmission is stable, and the working performance of a card punching machine is improved.
Description
Technical field
The present invention relates to a kind of gear transmission structure, the cam shaft group particularly relating to a kind of punched-card machine is installed.
Background technique
Punched-card machine is used to the specification company personnel commuter time, is now used by most company at present, setup times on punched-card machine, the time of commuter time on punched-card machine is as the criterion, after utilizing punched-card machine writing time, settle accounts the wage of employee according to the time of checking card, thus disapprove and make mistakes.Be provided with multiple gear for transmission in punched-card machine, install as gear and get along well you, just directly can affect the service behaviour of punched-card machine.
Therefore those skilled in the art are devoted to develop a kind of punched-card machine improving service behaviour.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide a kind of punched-card machine improving service behaviour.
For achieving the above object, the invention provides a kind of gear transmission structure, comprise support and rotating shaft, one end of rotating shaft is set to connecting rod; One end of rotating shaft is arranged with the first driving gear, and the other end of rotating shaft is provided with the second driving gear and the 3rd driving gear;
Second driving gear offers the perforation identical with connecting rod diameter, and the second driving gear is set on connecting rod by perforation;
3rd driving gear is provided with projection, projection offers limit chamber identical with connecting rod diameter; 3rd driving gear is connected with the end face of connecting rod by limit chamber;
Rotating shaft two ends are arranged on the first side wall on support and the second sidewall, and the first driving gear, the second driving gear and the 3rd driving gear are all arranged on the inner side of the first side wall and the second sidewall.
Rotating shaft is cam shaft.
The invention has the beneficial effects as follows: the present invention can reduce external disturbance, stable transmission, improve the service behaviour of punched-card machine.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is assembly structure schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples
The invention will be further described:
As Figure 1-Figure 2, a kind of gear transmission structure, comprises support 10 and rotating shaft 20, and one end of rotating shaft 20 is set to connecting rod 21; One end of rotating shaft 20 is arranged with the first driving gear 30, and the other end of rotating shaft 20 is provided with the second driving gear 40 and the 3rd driving gear 50;
Second driving gear 40 offers the perforation identical with connecting rod 21 diameter, and the second driving gear 40 is set on connecting rod 21 by perforation; This connecting rod 21 can strengthen socket, prevents from skidding.
3rd driving gear 50 is provided with projection 51, projection 51 offers and the identical limit chamber of connecting rod 21 diameter; 3rd driving gear 50 is connected by the end face of limit chamber with connecting rod 21;
Rotating shaft 20 two ends are arranged on the first side wall 11 on support 10 and the second sidewall 12, and the first driving gear 30, second driving gear 40 and the 3rd driving gear 50 are all arranged on the inner side of the first side wall 11 and the second sidewall 12.Rotating shaft 20 is cam shaft.The component such as the first driving gear 30, second driving gear 40 and the 3rd driving gear 50 are all arranged on the inner side of the first side wall 11 and the second sidewall 12, assembly is made to install concentratedly between the first side wall 11 and the second sidewall 12, thus effectively reduce the boundary dimension of punched-card machine, be convenient to install and transport, saved cost simultaneously.
In the present embodiment, the first driving gear 30 is arranged on the inwall of the corresponding sidewall of support through the 4th gear 60 connecting motor the 70, four gear 60, to be unlikely to evagination, the built-in installation of the first driving gear 30, can reduce external disturbance, stable transmission, thus improve stability of the present invention.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment.
