Abstract

The invention relates to a gear driving mechanism for the upper cutter frame and the lower cutter frame of the flying shear, in particular to a gear driving mechanism with variable working conditions. The gear driving mechanism comprises a main drive gear, a lower cutter frame drive gear and an upper cutter frame drive gear which are mutually meshed and arranged on a main drive shaft and eccentric shafts of the upper and the lower cutter frames, wherein, the upper cutter frame drive gear is composed of a gear core, a master gear, a pinion, an eccentric regulating shaft and bolts, wherein the gear core is connected with the eccentric shaft of the upper cutter frame, and the master gear and the pinion are arranged on the outer circle of the gear core in series; the eccentric regulating shaft is arranged between the pinion and the gear core; a plurality of connecting holes are respectively arranged on the identical circumference of the gear core, the master gear and the pinion, and the bore diameters of the connecting holes on the pinion are slightly larger than that of the connecting holes on the master gear and the gear core; the gear core, the master gear and the pinion are connected through the bolts penetrating through each connecting hole. The gear driving mechanism has the advantages that the clearances between the meshed gears are effectively eliminated, the driving error is overcome, and the impaction between the gears generated due to the clearances is eliminated as well.

Description

technical field [0001] The invention relates to a gear transmission mechanism with variable working conditions, in particular to a transmission mechanism for eliminating the transmission error and inter-gear impact vibration caused by the gap between transmission gears caused by the alternating force of a flying shear. Background technique [0002] The trajectory of the upper and lower tool holders of the double crankshaft flying shear is to maintain relative circular motion on the same vertical plane. According to the nature of the action, it can be divided into board chasing motion and return motion, and the shearing of the board is completed between the two actions. When cutting the sheet, a reverse force is generated between the upper and lower knives. Because the transmission gears of the upper and lower tool holders are meshed with each other, there is a gap between the transmission gears between the upper and lower tool holders. The reverse force will cause collision...
