Embodiment 1
[0031] Embodiment one: if figure 1 As shown, the present embodiment drives the rolling mill independently, including a roll box, a gear box and a motor 1, one motor 1 corresponds to one gear box, and the motor 1 and the gear box are connected through a transmission device 2, and one gear box corresponds to one roll box , and the gear box and the roller box are connected through gear transmission.
[0032] In this embodiment, the transmission device 2 is a shaft coupling.
[0033] In this embodiment, the gearbox includes an input shaft 3, a first output shaft 4 and a second output shaft 5, the input shaft 3 is connected to the motor 1 through a coupling, and the input shaft 3 is provided with a first gear 6, so The first output shaft 4 is provided with a second gear 7 and a third gear 8, the second output shaft 5 is provided with a fourth gear 9, the first gear 6 meshes with the second gear 7, and the first The third gear 8 meshes with the fourth gear 9;

Embodiment 2
[0037] Embodiment two: if image 3 As shown, the present embodiment drives the rolling mill independently, including a roll box, a gear box and a motor 1, and one motor 1 corresponds to a gear box, and the motor 1 and the gear box are connected by a transmission device 2, and a gear box corresponds to a roll box, And the gear box and the roller box are connected through gear transmission.
[0038] In this embodiment, the transmission device 2 is a shaft coupling.
[0039] In this embodiment, the gearbox includes an input shaft 3, a first output shaft 4, a second output shaft 5 and an intermediate shaft 14, the input shaft 3 is connected to the motor 1 through a coupling, and the input shaft is provided with a first gear 6. The first output shaft 4 is provided with a second gear 7 and a third gear 8, the second output shaft 5 is provided with a fourth gear 9, and the intermediate shaft 14 is provided with a seventh gear 15 and eighth gear 16;
[0040] The first gear 6 meshes...
Embodiment 3
[0044] Embodiment three, such as Figure 5 As shown, this embodiment is a further improvement on Embodiment 2. The difference between this embodiment and Embodiment 2 is that the second gear 7 and the eighth gear 16 are bevel gears; and in this implementation, the first output shaft 4 and The second output shaft 5 and the intermediate shaft 14 are arranged staggered at 45°. This improvement can make the whole rolling mill in a state of horizontal arrangement, and realize the twist-free rolling at 45° at the top.

Abstract
The invention discloses a single transmission mill which comprises a roll box, a gearbox and a motor; one motor corresponds to one gearbox, and the motor and the gearbox are in transmission connection through a transmission device; one gearbox corresponds to one roll box, and the gearbox and the roll box are in transmission connection through a gear. According to the single transmission mill, because each mill is driven by the single motor, an equipment structure is greatly simplified compared with centralized transmission, simple and compact, so that the stability in high-speed operation is improvedfavorably; when the roll collar of any one mill is worn, the reduction of the roll diameter caused by the wear of the roll collar is made up for by finely adjusting the speed of the motor, so that the utilization rate of the roll collar can be improved, and the quantity of the spare parts of the roll collar is reduced; in addition, no fixed pressure ratio exists between single gates, so that the hole shape design is more flexible; meanwhile, the power of the motor is lower, fewer spare parts are required, and the investment, production and operation costs can be effectively reduced.
Description
technical field [0001] The invention relates to a rolling mill, in particular to a high-speed cantileverrolling mill. Background technique [0002] In modern wire rod production, the method of increasing the final rolling speed of wire rod is usually adopted to obtain higher output. At present, the guaranteed final rolling speed of high-speed wire rod production can reach 110m / s or even higher. In order to achieve such a high rolling speed, a suitable high-speed wire rod rolling mill is required. The currently widely used equipment is a wire rod finishing mill. Through high-speed rolling of a wire rod finishing mill, products that meet the size requirements can be obtained and the output of wire rods can be guaranteed. In the past, the dynamic speed drop in the high-speed rolling process could not be solved at such a high rolling speed, so the traditional wire rod finishing mills used centralized transmission, that is, a large motor simultaneously drives 8 to 10 wire rod f...
