Abstract
The utility model provides a driving device of a finishing area small-sized multi-motor, which comprises a finishing mill group, a five-axis horizontal type increasing speed gearbox, a direct current motor A, a direct current motor B, a direct current motor C, a direct current motor D and a speed increasing box, wherein every two direct current motors of the four direct current motors are connected in parallel after being connected in series, and the direct current motors output rotating speed at work and transport power on the finishing mill group through the five-axis horizontal type increasing speed gearbox and the speed increasing box. The driving device of the finishing area small-sized multi-motor is used through connecting the direct current motors in parallel after connecting in series, and is a novel driving device. An electric control system is localized through using the direct current motors, and the electric control cost of high speed metallurgical wire finishing area equipment is effectively reduced in the field practical application. An integrated driving structure has convenient mounting on field, simple debugging, steady quality, long service life, low failure rate of equipment and convenient equipment and electric control use and maintenance, the service performance can reach to the using standard of high speed metallurgical wires, and the driving device of the finishing area small-sized multi-motor can completely replace an existing conventional driving device.
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 transmission device that is applicable to the small-sized many motors in high-speed wire finish-rolling district.
(2) background technology
Along with the privately owned capital input of high-speed rod project in recent years constantly increases in China, under the constant situation of former serviceability, reduce cost of investment, become our primary task at present.
Existing design is adopted 1 5500KW, 1500n/min alternating-current variable frequency motor and gearbox to be connected to mm finishing mill unit power source is provided, but its supporting automatically controlled frequency conversion system is immature because of domestic technique, all adopts foreign system.The cost height is debugged loaded down with trivial detailsly, is not easy to domestic related personnel and grasps and can't make the problem that occurs in the later stage use such problem such as corresponding techniques support and perplexing us always.Through demonstration, adopt dc micro-motor to substitute alternating-current variable frequency motor, but the turn up of direct current generator is less than the requirement of original design.This just requires us under the constant situation of equipment serviceability, creates a kind of new transmission device and comes guaranteed cost, falls cost.
(3) summary of the invention
The purpose of this utility model is to provide the transmission device of the small-sized many motors in a kind of high-speed wire finish-rolling district.This apparatus structure is simple, operate steadily, and reduced manufacturing cost.
The technical scheme that its technical problem that solves the utility model adopts is: this device adopts four direct current generators that power is provided, the direct current generator first is connected with direct current generator second, direct current generator third is connected with the direct current generator fourth, the group of motors of these two series connection is connected with five horizontal speed-increasing transmissions respectively, five horizontal speed-increasing transmissions are connected with gearbox, and gearbox is connected with mm finishing mill unit.
Adopt after the technique scheme, this transmission device has following advantage: the kind of drive is simple, drive mechanism is compact, stable drive; Adopt direct current generator, control system is significantly simplified, and effectively reduces cost; The whole kind of drive is applied to that noise is low in the practice, the shake value is little, it is big to transmit moment of torsion; Adopt micro-machine, reduce cost, convenient debugging and monitoring; Adopt this kind transmission device to remedy the dc micro-motor maximum speed and do not reach the problem that designing requirement brings.
The utility model is by in parallel use the in direct current generator series connection back, and this is a kind of novel transmission device.Adopt direct current generator, 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, steady quality, long service life, equipment failure rate is low, equipment and automatically controlled working service are convenient, and serviceability has reached the use standard of the metallurgical wire rod of high speed, can substitute existing conventional transmission device fully.
