Abstract
The utility model provides a speed increasing structure for reaching final output rotating speed by adding a speed increasing gearbox. The peed increasing structure comprises a precision rolling machine set, the speed increasing gearbox, a DC motor and a step-up box. During the working process, the output speed of the DC motor ensures that power is transmitted to the precision rolling machine set by passing through the speed increasing gearbox and the step-up box. A transmission structure of the utility model adopts the DC motor, and the application of electrical control system domestication to on-site practice reduces the electrical control cost of equipment in a high-speed metallurgical wire precision rolling area. The on-site installation of the entire transmission structure is convenient, the debugging is simple, the service life is long, the equipment failure rate is low, the use and the maintenance of the equipment and the electrical control system are convenient, and the operational performance completely reaches the using standard of the high-speed metallurgical wires.
Description
(1) technical field
The utility model relates to the actuating unit in a kind of metallurgical high-speed wire finish-rolling district, is specifically related to a kind of power multiplying gear that is applicable to high-speed wire finish-rolling district direct current generator.
(2) background technology
Along with high-speed rod project in recent years constantly increases in China, a lot of privately owned capitals change the high line of investment over to, and private firm's insufficient funds become the common fault of private firm, and this just requires us to reduce cost under the constant situation of existing equipment serviceability.Wherein finish rolling district master motor adopts direct current generator to replace alternating-current variable frequency motor to become the emphasis that reduces whole line cost.
In former design, the power source of the high line of whole piece is selected ac variable-frequency electric motor for use, control system adopts the ABB frequency-changing control system, but because of domestic technique falls behind, can't do the corresponding techniques support to equipment debugging and normal problems occured in operation, run into this type of situation and often will engage the foreign technology expert to solve, increased original cost virtually, also caused the increase in plant maintenance cycle simultaneously.After adopting direct current generator, control system is simplified significantly, and the support of domestic technique can solve any problem of debugging and emerged in operation fully.The expenditure contrast of two aspects adopts direct current generator can save ten thousand yuans of 500-600.But because of the direct current generator maximum (top) speed does not reach application requirements, must make amendment to the existing speedup structure of high-speed rod, this just requires us to adopt between former booster engine and direct current generator increases a speed-increasing transmission and guarantees newly-designed requirement.
(3) summary of the invention
The purpose of this utility model is to provide a kind of power multiplying gear that is applicable to high-speed wire finish-rolling district direct current generator.
The purpose of this utility model is achieved in that
Form by speed-increasing transmission (2), direct current generator (3), gearbox (4), mm finishing mill unit (1), described direct current generator (3) connects speed-increasing transmission (2), speed-increasing transmission (2) connects gearbox (4), and gearbox (4) connects mm finishing mill unit (1) again; Direct current generator (3) output speed arrives transmission of power on the mm finishing mill unit (1) by speedup speed change (2) case and gearbox (4).
Adopt after the technique scheme, this drive mechanism has following advantage:
1, simple, the stable drive of drive mechanism.
2, adopt direct current generator to replace alternating-current variable frequency motor, control system is significantly simplified, and has saved cost.
3, drive mechanism compactness, it is little to take up room.
4, whole drive mechanism is applied to that noise is low in the practice, the shake value is little, to transmit moment of torsion big.
(4) description of drawings
Fig. 1 is an embodiments of the invention drive mechanism schematic diagram;
Among the figure 1, mm finishing mill unit, 2, speed-increasing transmission, 3, direct current generator, 4, gearbox.
(5) specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the invention provides and a kind ofly reach the speedup structure that finally requires output speed by increasing a speed-increasing transmission.Comprise: mm finishing mill unit (1), speed-increasing transmission (2), direct current generator (3), gearbox (4).Direct current generator during work (3) output speed arrives transmission of power on the mm finishing mill unit (1) by speed-increasing transmission (2) and gearbox (4).
Drive mechanism of the present utility model adopts direct current generator, and the electric-control system production domesticization is applied to and has effectively reduced the automatically controlled cost of the metallurgical finishing wire of high speed district's equipment in the on-the-spot reality.Whole drive mechanism is easy for installation at the scene, and debugging is simple, long service life, and equipment failure rate is low, and equipment and automatically controlled working service are convenient, and serviceability has reached the use standard of the metallurgical wire rod of high speed fully.
Claims (1)
1. speedup structure that is applicable to high-speed wire finish-rolling district direct current generator, it is characterized in that it comprises speed-increasing transmission (2), direct current generator (3), gearbox (4), mm finishing mill unit (1), described direct current generator (3) connects speed-increasing transmission (2), speed-increasing transmission (2) connects gearbox (4), and gearbox (4) is connected to mm finishing mill unit (1) again; Direct current generator (3) output speed arrives transmission of power on the mm finishing mill unit (1) by speedup speed change (2) case and gearbox (4).
