Abstract
The invention discloses a gear transmission device of a double-point punch, which comprises a transmission gear fixed on a transmission shaft and two main gears driven by the transmission gear. The transmission gear is connected with a power device through the transmission shaft. The gear transmission device is characterized in that the two main gears are mutually and separately arranged on two sides of the transmission gear, at least one of the two main gears is indirectly meshed with the transmission gear through an idler wheel mechanism. The gear transmission device has the advantages that: the outside diameter of the main gear can expand the space between fulcrums in the range of not interfering the inner width of a body, the compressive capacity of eccentric load in the left and right directions can be greatly improved by expanding the space between two fulcrums, and simultaneously the dynamic precision in multi-process punch processing aspects such as transfer processing and the like; because the transmission gear become small, the inertia of a punch transmission train becomes small, and then the running properties such as starting, stopping and the like are improved; and the space between the fulcrums can be freely selected by changing the tooth number of idler wheels in the idler wheel mechanism and the number of the idler wheels.
Description
Technical field
The present invention relates to a kind of transmission device of punch press, especially relate to a kind of gear drive of double-point punch.
Background technology
Double-point punch mainly drives crankshaft-and-connecting-rod by the set of gears transmission device and drives slide block movement, pumps by slide block and carries out punching press.The gear drive of existing plain edition double-point punch as shown in Figure 1, two master gear and drive pinions that directly mesh mutually about it comprises, drive pinion is connected with power set by power transmission shaft, drive pinion and one of them master gear mesh and drive another master gear by this master gear, and Here it is so-called " the tandem kind of drive ".
But the gear drive of this mode exists the problem of two aspects:
The revolving force that applies on each gear teeth face of one for the whole required moment of torsion of punch press is: the driven master gear of i → 1/2; Ii driving pinion → 1/2+1/2=1; Iii drive pinion → 1; Because flank of tooth intensity needs integral body " 1 ", cause tooth to fracture easily, so the tooth on the gear just requires thicker bigger.
It two is master gear directly engagements each other, so that master gear becomes is big, causes the body inner width and is restricted, thereby can not enlarge length of support.(length of support (C) is less than 1/2 of the body inner width).
Summary of the invention
Technical problem to be solved by this invention provides a kind of, gear drive that can preferably enlarge the wide type double-point punch of length of support lower to flank of tooth requirement of strength.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of gear drive of wide type double-point punch, comprise travelling gear and two master gears that drive by described travelling gear that are fixed on the power transmission shaft, described travelling gear is connected with power set by power transmission shaft, described two master gears are separated from each other the both sides that are arranged on described travelling gear, and at least one master gear in described two master gears meshes indirectly by idler mechanism and described travelling gear.
Described idler mechanism is an idle pulley, and a master gear in described travelling gear and described two master gears meshes indirectly by described idle pulley, and another master gear and described travelling gear in described two master gears directly mesh.
The center of circle of described travelling gear, described two master gears and described idle pulley all is positioned on same the horizontal line.
Compared with prior art, advantage of the present invention is that two master gears are separated from each other, and meshes indirectly by an idler mechanism, has constituted " the parallel kind of drive ".At first, the flank of tooth intensity of this kind of drive master gear is all just passable with 1/2 torque load, therefore flank of tooth intensity is compared with previous model and can be 1/2, by the LOAD FREQUENCY of dividing load to draw for 2 times about 1 travelling gear of punch press running is in the past 2 times, yet these mechanical strength designs are exactly " unlimited design " originally, even therefore LOAD FREQUENCY is 2 times, and is also no problem on design strength.Secondly, the rotation torque of travelling gear is equivalent to that left and right sides master gear flank of tooth intensity 1/2+1/2=1 determines, and be that design by the strength of gear teeth can make master gear diminish therewith relatively, the master gear external diameter is under the scope of not interfering the body inner width, can enlarge length of support, and can improve compression capability significantly to the left and right directions eccentric load by enlarging distance between fulcrum, can improve significantly simultaneously in the dynamic accuracy aspect the punch press processing of sending multiple operation such as processing grade; Because each travelling gear diminishes, the inertia of punch press power train diminishes, behavior in service such as also therefore improved startup, stop; The present invention can freely select length of support by the number of teeth and the idle pulley quantity that change the idle pulley in the idler mechanism.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Embodiment: shown in Fig. 2 ~ 4, a kind of gear drive of wide type double-point punch, comprise travelling gear 2 and two master gear 3 and the master gears 3 ' that drive by travelling gear 2 that are fixed on the power transmission shaft 1, travelling gear 2 is connected with power set 5 by power transmission shaft 1, master gear 3 and master gear 3 ' are separated from each other the both sides that are arranged on travelling gear 2, travelling gear 2 meshes by idle pulley 4 indirectly with master gear 3, and master gear 3 ' directly meshes with travelling gear 2.The center of circle of master gear 3, master gear 3 ', travelling gear 2 and idle pulley 4 all is positioned on same the horizontal line.
In the foregoing description, travelling gear 2 also can be wholely set on power transmission shaft 1, and travelling gear 2 also can mesh by one group of idle pulley indirectly with master gear 3, and master gear 3 ' also can mesh indirectly by one group of idle pulley and travelling gear 2.
