Abstract
The utility model relates to a novel transmission device of a withdrawal and straightening machine for square and round billets. The transmission device comprises an upper withdrawal and straightening roller, a lower withdrawal and straightening roller, an electric motor, a first-stage speed reducer, a universal coupling, a bevel gear wheel speed reducer and a stander, wherein the upper withdrawal and straightening roller and the lower withdrawal and straightening roller are respectively arranged on the stander; the output shaft of the electric motor is connected with the first-stage speed reducer; the output shaft of the first-stage speed reducer is connected with the input shaft of the bevel gear wheel speed reducer through the universal coupling; and the output shaft of the bevel gear wheel speed reducer is connected with the lower withdrawal and straightening roller. The device is not easy to heat and damage by using two-stage transmission. The device by using the bevel gear wheel speed reducer has the advantages of high transmission efficiency, large load and not high requirement for machining precision. The device by using the connecting type of the universal coupling permits a deviation with a certain angle between the first-stage transmission and the second-stage transmission, and has a certain expansion amount; and the mounting requirements of horizontal precision and vertical precision are not high. The device is in rigid transmission which is different from chain transmission in the rotation direction; and the device is high in transmission efficiency, stable and reliable, and in-time in response.
Description
Technical field
The utility model relates to a kind of novel side, circle base straightening machine transmission device.
Background technology
The straightening machine is the power source of throwing, also is simultaneously the pressure source of aligning strand.Can the quality of straightening machine is directly connected to continuous casting production carry out smoothly, is one of key equipment in the conticaster.
Domestic common straightening machine all is similar aspect aligning, and the use aspect does not have open defect yet; Mainly containing following several kinds of modes aspect the throwing (transmission device):
1, one-level transmission: each transmission device is made up of a motor and a reductor, and is as shown in Figure 1;
2, secondary transmission: each transmission device is made up of a motor, two reductors and intermediate connecting shaft;
The transmission of domestic straightening machine secondary mainly contains two kinds of worm-gear speed reducer+Hooks coupling universal coupling form and worm-gear speed reducers+double strand chain stiff shaft form.The structure of worm-gear speed reducer+Hooks coupling universal coupling form is as shown in Figure 2, and the structure of worm-gear speed reducer+double strand chain stiff shaft form is as shown in Figure 3.
One-level transmission transmission device is too near from strand, and heating damages easily, must adopt water-cooled machine and water-cooled reductor; Nonetheless, to compare fault rate still higher with the secondary transmission, needs often to change spare part.
With worm-gear speed reducer+Hooks coupling universal coupling form secondary transmission, the worm-gear speed reducer transmission efficiency is low, and it is little to load, and high to requirement on machining accuracy, and self-lock ability is good.Be used on the straightening machine, worm-gear speed reducer is shorter relatively service life; And because the machining accuracy problem, often cause strand bullet base, influence fiery cutter cutting, when serious even cause stopping production.
Worm-gear speed reducer+double strand chain stiff shaft form secondary transmission, double strand chain stiff shaft type of belt drive first class reducer output shaft and 2-level reducer power shaft must guarantee high concentricity, and be high to installation requirement; The stiff shaft concentricity can not guarantee fully, and adopts chain drive, largely reduced transmission efficiency, between sprocket wheel and the chain certain clearance arranged, and makes this kind kind of drive poor stability, and in time respond is poor.
Summary of the invention
The purpose of the utility model is in order to overcome the following problem that above-mentioned prior art exists: 1, motor, reductor weak point in service life need often to change spare part; 2, the casting process base phenomenon of being hit by a bullet; And a kind of novel side, circle base straightening machine transmission device be provided.
The technical scheme of the utility model is:
Novel side, circle base straightening machine transmission device; Comprise straightening roller, following straightening roller, motor, first class reducer, Hooks coupling universal coupling, bevel gear reductor, frame; Last straightening roller, following straightening roller are installed on the frame respectively; The output shaft of motor links to each other with first class reducer, it is characterized in that: the output shaft of first class reducer links to each other with the power shaft of bevel gear reductor through Hooks coupling universal coupling, and the output shaft of bevel gear reductor links to each other with following straightening roller.
The utility model adopts the secondary transmission, and the transmission device stow away from heat is not easy to generate heat impaired.Can adopt ventilated machine.The utility model adopts the bevel gear reductor.The bevel gear reductor has transmission efficiency high, and load is big, to the less demanding advantage of machining accuracy.Be used on the straightening machine, can prolong reductor service life, reduce Parts Inventory quantity, shorten the stopping production maintenance time.The most important thing is to solve the strand bullet base problem that always perplexs many iron and steel enterprises.The utility model adopts the Hooks coupling universal coupling connected mode.Hooks coupling universal coupling allows between one-level transmission and the secondary transmission deviation of certain angle is arranged, and certain stroke is arranged, and requires not high to horizontal accuracy and vertical precision are installed.Being different from chain drive in rotation direction, is positive drive, and transmission efficiency is high, and reliable and stable, and reaction in time.

The specific embodiment
In conjunction with accompanying drawing the utility model is done further to describe.
As shown in Figure 4; The utility model comprises straightening roller 3, following straightening roller 1, motor 5, first class reducer 6, Hooks coupling universal coupling 7, bevel gear reductor 12, frame; Last straightening roller 3, straightening roller 1 is installed on the frame respectively down; The output shaft of motor 5 links to each other with first class reducer 6, and the output shaft of first class reducer 6 links to each other with the power shaft of bevel gear reductor 12 through Hooks coupling universal coupling 7, and the output shaft of bevel gear reductor 12 links to each other with following straightening roller 1.Strand 2 is placed between straightening roller 3 and the following straightening roller 1.
The utility model adopts the secondary transmission, and the transmission device stow away from heat is not easy to generate heat impaired.Can adopt ventilated machine.The utility model adopts the bevel gear reductor.The bevel gear reductor has transmission efficiency high, and load is big, to the less demanding advantage of machining accuracy.Be used on the straightening machine, can prolong reductor service life, reduce Parts Inventory quantity, shorten the stopping production maintenance time.The most important thing is to solve the strand bullet base problem that always perplexs many iron and steel enterprises.The utility model adopts the Hooks coupling universal coupling connected mode.Hooks coupling universal coupling allows between one-level transmission and the secondary transmission deviation of certain angle is arranged, and certain stroke is arranged, and requires not high to horizontal accuracy and vertical precision are installed.Being different from chain drive in rotation direction, is positive drive, and transmission efficiency is high, and reliable and stable, and reaction in time.
