Abstract
The utility model discloses a kind of eccentric structure of large tonnage pressing machine, the utility model comprises eccentric body, connecting rod, eccentric shaft and eccentric gear, connecting rod is fixedly installed on eccentric body, eccentric body rotates and is arranged on eccentric shaft, described eccentric gear has two, eccentric body is between two eccentric gears, and two eccentric gears are all fixed on eccentric body.The utility model can meet the needs of little table top great tonnage press Large-torsion transmisson, and imports into due to the eccentric gear of power from both sides, good stability simultaneously, improves the stationarity of transmission.And the utility model compact conformation, reduces material, reduces production cost.
Description
Technical field
The utility model relates to a kind of eccentric structure of large tonnage pressing machine.
Background technology
The eccentric structure of traditional large tonnage pressing machine adopts a large eccentric gear and monolithic linkage, and easily cause the unbalance stress of cross girder, transmission is unstable.Large for nominal pressure stroke, energy requirement is high, the great tonnage press of the eccentric gear face width of tooth, and adopt an eccentric gear structure, cross girder structure is widened, and increases production cost.
Utility model content
The technical problems to be solved in the utility model is: the eccentric structure providing a kind of large tonnage pressing machine of good stability.
In order to solve the problems of the technologies described above, the utility model comprises eccentric body, connecting rod, eccentric shaft and eccentric gear, connecting rod is fixedly installed on eccentric body, eccentric body rotates and is arranged on eccentric shaft, described eccentric gear has two, eccentric body is between two eccentric gears, and two eccentric gears are all fixed on eccentric body.
In order to easy to process, described two eccentric gears are respectively by pin and the both sides being bolted to eccentric body.
In order to realize moving back and forth, described connecting rod is divided into upper and lower two parts by the plane of the center line by eccentric body, and connecting rod inside is provided with connecting rod bearing shell, and connecting rod bearing shell comprises two semicircular ring watt bodies, two semicircular ring watt are arranged on connecting rod by pin, and two parts up and down of connecting rod are fixed by screw.
In order to reduce wear, between described eccentric body and eccentric shaft, eccentric bearing pad is installed.
The beneficial effects of the utility model are: the utility model can meet the needs of little table top great tonnage press Large-torsion transmisson, and import into due to the eccentric gear of power from both sides, good stability simultaneously, improve the stationarity of transmission.And the utility model compact conformation, reduces material, reduces production cost.

Detailed description of the invention
The eccentric structure of large tonnage pressing machine as shown in Figure 1, comprise, eccentric gear 3, connecting rod bearing shell top 4, eccentric body 5, eccentric shaft 6, connecting rod bearing shell bottom 7 and connecting rod 9.
Whole eccentric structure is arranged in crossbeam 8, and eccentric shaft 6 is fixed on crossbeam 8, crossbeam 8 is also provided with the jackshaft 1 of rotation, jackshaft 1 has two process all-in-one-piece idler gear 2 with jackshaft 1.
Connecting rod 9 is fixedly installed on eccentric body 5, eccentric body 5 rotates and is arranged on eccentric shaft 6, and eccentric gear 3 has two, and eccentric body 5 is between two eccentric gears 3, two eccentric gears 3, respectively by pin and the both sides being bolted to eccentric body 5, form eccentric duplicate gear.Connecting rod 9 is divided into upper and lower two parts by the plane of the center line by eccentric body 5, form connecting rod top 10 as shown in Figure 2 and connecting rod bottom 11, connecting rod 9 inside is provided with connecting rod bearing shell, connecting rod bearing shell comprises connecting rod bearing shell top 4 and connecting rod bearing shell bottom 7, connecting rod bearing shell top 4 and connecting rod bearing shell bottom 7 are fixed on connecting rod top 10 and connecting rod bottom 11 respectively by pin.Connecting rod top 10 and connecting rod bottom 11 are by the fixing rear formation monolithic linkage 9 of screw.Eccentric bearing pad 12 is installed between eccentric body 5 and eccentric shaft 6.
Two idler gears 2 and two eccentric gears 3 engage one by one.Idler gear 2 and eccentric gear 3 are straight-tooth gear.
Operation principle: driving force passes to two eccentric gears, 3, two eccentric gears 3 by two idler gears 2 and drives eccentric body 5 to rotate, and eccentric body 5 drivening rod 9 moves reciprocatingly.
