[0002] At present, the transmission device of the rolling mill is driven by the main motor to drive the reducer and drive a high-speed rotating shaft. The high-speed rotating shaft drives two parallel small gears. A low-speed rotating shaft is connected together, and finally the large connecting rod connected with the crank gear is reciprocated. One end of the large connecting rod is connected with the main frame, and then the main frame of the cold rolling mill is reciprocated. The structure is roughly the same, except that the main motor directly drives a small pulley in the pulley transmission, and then the large pulley that acts as a decelerator drives the high-speed rotating shaft to rotate. Due to the large current fluctuation of the transmission during the working process, the cold rolling mill is rolling. Unstable under the control state, which affects the product quality

Embodiment Construction
[0011] According to the attached figure 1 Describe the present invention in detail;
[0012] The transmission mechanism of the cold rolling mill is composed of a main transmission device and a driven transmission device. The gears 5, 6 and the laterally arranged connecting rods 7, 8 respectively driven by the crank gears 5, 6 are composed of a vertical drive between the main transmission and the driven transmission, which is driven by the main reducer 2 and drives the driven transmission. The high-speed drive shaft 9 rotated by the small gears 3 and 4 in the device, the high-speed drive shaft 9 between the main transmission device and the driven transmission device is connected with an independently rotating large flywheel 10 that can play a compensating role, and the connecting rod 7 is connected to the main engine The upper end of the main frame 11 described in the frame 11 is provided with a handle, and the outer diameter of the large flywheel 10 is 50 mm. The large flywhe...

Abstract
The invention relates to a cold rolling mill transmission mechanism. The cold rolling mill transmission mechanism consists of a main transmission device, a driven transmission device and a connectionshaft. The main transmission device consists of a main motor and a main speed reducer. The driven transmission device consists of pinion gears and crank gears which are engaged with each other for transmission and connecting rods which are driven by the crank gears and transversely arranged. The dual transmission device can store excess energy through a flywheel so as to increase kinetic energy and instantaneous speed. On the contrary, when resistance work is greater than driving work, the stored energy can be released to supplement the insufficiency of the driving work and reduce the instantaneous speed. Relying on the large moment of inertia of the flywheel, the accumulated kinetic energy is used to help overcome peak load and reduce power required by a prime mover. Therefore, the inertia and inertia moment of frame reciprocating motion are compensated, the energy consumption is reduced, and the quality of products is ensured.
