Abstract
The utility model relates to a cold press rolling mill double-transmission device including a main transmission device, a driven transmission device and a connecting shaft. The main transmission device is composed of a main motor and a main speed reducer, the driven transmission device includes a first pinion and a first crank bull gear which are in a mutually engaged transmission, and a transversely arranged first connecting rod driven by the first crank bull gear. The double-transmission device can store the excess energy via a flywheel to increase the kinetic energy and instantaneous velocity, reversely, when the work of resistance is greater than the work of driving, the stored energy can be released to supplement the insufficient of the working of driving and to reduce the instantaneous velocity, and depending on the large rotating inertia moment of the flywheel, the double-transmission device makes use of the stored kinetic energy to overcome the peak load to reduce the needed power of a prime mover, thereby compensating the inertia and inertia moment of the reciprocating motion of a frame. Therefore, the double-transmission device not only reduces the energy consumption, but also ensures the product quality.
Description
Technical field
The utility model belongs to the milling train field for rolling metal strip, particularly a kind of milling train dual transmission of colding pressing.
Background technology
At present, the milling train transmission device of colding pressing 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 respectively driving and the separately crank gear wheel rotation of engaged transmission, 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 device and above-mentioned structure are roughly the same, it is a small belt pulley in the main motor direct-drive pulley gear, driving high speed rotating shaft by the big belt pulley that plays decelerating effect again rotates, because in the course of the work current fluctuation amplitude of transmission device is large, causes cold pilger mill unstable under as-rolled condition, has affected product quality
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of transmission process milling train dual transmission of colding pressing stably is provided, and the energy in the transmission process is regulated, and makes cold rolling mill more steady in the operation of rolling, Improving The Quality of Products.
The utility model is achieved through the following technical solutions:
This milling train dual transmission of colding pressing, formed by main drive, driven transmission device and connecting axle, main drive is made of main motor and main gear reducer, and driven transmission device comprises the first pinion of intermeshing transmission and the first crank gear wheel and the first connecting rod of the horizontally set that driven by the first crank gear wheel forms.Be connected with the large flywheel of the independent rotation of a redeeming on the high-speed driving axle between main drive and the driven transmission device.Described large flywheel is arranged on the connecting axle by clutch shaft bearing, and the two ends of described connecting axle are connected with main gear reducer rotating shaft, high-speed driving axle respectively by the first shaft coupling.The beneficial effects of the utility model:
The utility model connects flywheel at 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 larger rotary inertia of flywheel, the kinetic energy that utilizes its savings helps overcome peakload and the power demand that reduces prime mover, has compensated the reciprocating inertia of frame and moment of inertia, both reduce energy consumption, guaranteed again the quality of product.
Description of drawings
Fig. 1 is this cold rolling mill dual transmission structural representation.
Among the figure, 1 is that main motor, 2 is respectively the first and second crank gear wheels, 7 and 8 and is respectively the first and second connecting rods, 9 and is respectively the first and second bearings, 15 and is respectively the first and second shaft couplings for connecting axle, 16 and 17 for low speed rotating shaft, 13 and 14 for mainframe, 12 for large flywheel, 11 for high-speed driving axle, 10 for main gear reducer, 3 and 4 is respectively the first and second pinions, 5 and 6.
