Abstract
The utility model relates to a gearing mechanism for a cold pipe rolling machine, which is composed of a main transmission mechanism and a driven transmission mechanism, wherein, the main transmission mechanism comprises a motor and a decelerator, the driven transmission mechanism comprises a pinion and a crank big gear which are mutually meshed and transmitted, and the driven transmission mechanism also comprises a connecting rod which is driven by the crank big gear. A high speed driving shaft which is arranged between the main driving mechanism and the driven driving mechanism is connected with an independently rotated big flywheel, kinetic energy which is accumulated by the big flywheel is used for overcoming a peak load and reducing required power of a prime mover, and inertia of reciprocal motion of a machine frame is compensated. Thus the rolling process of the rolling machine is steady, and the product quality can be improved.
Description
The utility model is a kind of cold pilger mill transmission mechanism.
At present, the cold-rolling mill transmission mechanism is by main driven by motor reductor and drives a high speed rotating shaft, this high speed rotating shaft drives two parallel pinions, two pinions and then driving and the crank gear wheel rotation of engaged transmission separately respectively, low speed rotating shaft of the common connection of two crank gear wheels, and finally make the big connecting rod reciprocally swinging that is connected with the crank gear wheel, big connecting rod one end links to each other with mainframe, and then make the mainframe working in reciprocating mode of cold-rolling mill, another kind of transmission mechanism and above-mentioned structure are roughly the same, it is a small belt pulley in the main motor direct-drive pulley transmission mechanism, driving high speed rotating shaft by the big belt pulley that plays decelerating effect again rotates, because transmission mechanism current fluctuation amplitude in the course of the work is big, cause cold pilger mill unstable under as-rolled condition, influenced product quality.
The purpose of this utility model is to provide a kind of transmission process cold pilger mill transmission mechanism stably.
The utility model is achieved in that the cold pilger mill transmission mechanism is made up of main drive gear and slave hand actuator, main drive gear comprises motor and speed reducer, slave hand actuator comprises the pinion of the transmission that is meshing with each other and crank gear wheel and the connecting rod that is driven by the crank gear wheel, be provided with between main drive gear and the slave hand actuator one by reductor drive and drive pinion rotation in the slave hand actuator the high-speed driving axle, but the high-speed driving axle between main drive gear and the slave hand actuator is connected with the big flywheel of the independent rotation of a redeeming.
The utility model is owing to be connected with flywheel on driving shaft, when the driving merit in the machine driving during greater than the work of resistance, this flywheel can get up unnecessary energy storages, kinetic energy and instantaneous velocity are increased, on the contrary, when the work of resistance when driving merit, the energy of storage can be discharged again, replenish and drive the not enough of merit and instantaneous velocity is reduced, rely on the bigger rotary inertia of flywheel, the kinetic energy that utilizes its savings helps overcome peakload and the power demand that reduces prime mover, reciprocating inertia of frame and moment of inertia have been compensated, the current fluctuation amplitude of machine operation is controlled in allowed limits, and cold pilger mill tends to be steady in the operation of rolling, helps the raising of product quality.
Below in conjunction with accompanying drawing the utility model is described in detail;
Fig. 1 is the structural representation sketch of the utility model cold pilger mill transmission mechanism.
The cold pilger mill transmission mechanism is made up of main drive gear and slave hand actuator, main drive gear comprises main motor 1 and main gear reducer 2, slave hand actuator comprises two groups of pinions 3 of the transmission that is meshing with each other, 4 and crank gear wheel 5,6 and by crank gear wheel 5, the connecting rod 7 of 6 separately-driven horizontally sets, 8 form, vertically be provided with one between main drive gear and the slave hand actuator by pinion 3 in main gear reducer 2 drives and the driving slave hand actuator, 4 rotate high-speed driving axle 9, but the high-speed driving axle 9 between main drive gear and the slave hand actuator is connected with the big flywheel 10 of the independent rotation of a redeeming, big flywheel 10 has played accumulation of energy, energy-conservation effect, mainframe 11 reciprocating inertia and moments of inertia have been compensated, the operation of rolling is tended to be steady, the big set-up mode of flywheel 10 on driving shaft 9 can have multiple, wherein, described big flywheel 10 is by bearing 13,14 are arranged on the connecting axle 15, the two ends of described connecting axle 15 are by shaft coupling 16,17 respectively with main gear reducer 2 rotating shafts, high-speed driving axle 9 connects, by main drive gear and connecting axle 15, the pinion 3 that driving shaft 9 drives in the slave hand actuator, 4, and then make crank gear wheel 5,6 drive connected connecting rod 7 respectively, 8 reciprocally swingings, finally make mainframe 11 reciprocally swingings, crank gear wheel 5,6 connect a low speed rotating shaft 12 altogether, and the utility model can be suitable for the machine driving of others equally.
