Abstract
The utility model discloses a novel heavy and medium plate rolling mill frame roller, which comprises three printed rollers respectively arranged in the front and on the back of a roller of a rolling mill, and is characterized in that a frame rollers adopts a door type quick-disassembly structure for connection with a frame, and a connecting shaft is driven by an alternating current frequency-conversion speed regulation motor, the connecting shaft is connected with a middle shaft, the other end of the middle shaft is connected with a transmission side shaft of the frame roller in an arc shaped toothed manner, thereby realizing driving of the frame roller. The novel heavy and medium plate rolling mill frame roller adopts the arc-shaped toothed connecting manner, has stable transmission, low noise, light and ingenious structure, small radial gap, excellent lubricating condition, small abrasion loss, convenient assembly, disassembly and maintenance and favor of increasing speed of the frame roller, improving product quality and prolonging service life.
Description
Technical field
The utility model relates to a kind of novel heavy and medium plate mill breast roll, is positioned at rolling-mill housing roll inlet and exit, is used for slab is sent into mill roll-gap smoothly and accepted the rolled piece that it shuts out, and makes steel billet enter into next equipment smoothly.
Background technology
Along with rapid development of national economy and hot rolled plate market competition are fierce day by day, industry-by-industry is increasing to the demand of hot rolled plate, and required sheet material specification is also different.Breast roll as key equipment is an imperative equipment in the Heavy Plate Production, and it also is to get in touch one of equipment the most closely with milling train.Breast roll is made up of breast roll body, gripping mechanism and transmission device etc.The breast roll body comprises forward and backward each three the colored roller of milling train, and bearing housing is an overall structure, and designed the jackshaft front end is the internal spline spline housing in the past, inserts breast roll by the hole on the mill housing column.
Breast roll is subjected to the influence of working roll and backing roll cooling water and iron scale because of being positioned at rolling-mill housing, the condition of work very severe, and the load that is hit is big.Because milling train pattern difference, slab specification difference, trimmed size difference are so the design type of breast roll is also inequality.Therefore, for satisfying new demand, it is also imperative constantly to adopt new structure to be improved in design to the heavy and medium plate mill breast roll.
Summary of the invention
The utility model purpose is to provide a kind of breast roll of novel heavy and medium plate mill.Technical solution of the present utility model is achieved in that
A kind of breast roll of novel heavy and medium plate mill, it is characterized in that: comprise being positioned at each forward and backward three colored roller of rolling mill roll, and connect axle by an ac variable frequency speed regulation motor-driven respectively, and connecing axle and be connected with jackshaft, the other end of jackshaft then is connected with the arc tooth pattern with breast roll transmission side shaft; Described breast roll all adopts the gate-type quick-disassembly structure to connect with frame.
Described gate-type quick-disassembly structure means by groove on the bearing block and valve the front and back breast roll is rigidly fixed on the rolling-mill housing.
The cooling water nozzle also is equipped with in the bottom of described breast roll.
Compared with prior art, the utility model has the advantages that conspicuously, mainly show
(1) splined changes the arc tooth into and connects, and has stable drive, noise is little, helps improving the speed of breast roll; Do not have impact shock and between centers string moving, radial clearance can be minimized, and helps improving the quality of products;
(2) lubricating condition is good, is convenient to safeguard; Structure is light and handy, and abrasion loss is little, and sail angle increases, easy accessibility, long service life;
(3) this axle can axial float, and this axle can pass in and out the external tooth head when mounting or dismounting, to be convenient for changing breast roll;
(4) the fixing gate-type structure that adopts the non-bolt formula of the chucking of breast roll, the boss of using on the rolling-mill housing is rigidly fixed in the front and back breast roll on the rolling-mill housing by valve and key.
Description of drawings
The utility model drawings attached 2 width of cloth, wherein:
Accompanying drawing 1 is the breast roll installation diagram;
Accompanying drawing 2 is the D-D cutaway view of Fig. 1.
The specific embodiment
Breast roll as a kind of novel heavy and medium plate mill of Fig. 1-Fig. 2.The breast roll body comprises rolling mill roll 7 forward and backward each three colored roller 1, all is independent transmissions.Breast roll adopts the gate-type quick-disassembly structure to connect with frame 6, by groove on the bearing block and valve 5 front and back breast roll 1 is rigidly fixed on the rolling-mill housing 6.The transmission of every breast roll 1 is driven by an ac variable frequency speed regulation motor 3 respectively and connects axle 2, connects axle 2 and is connected with jackshaft 8, and jackshaft 8 other ends are connected with the arc tooth pattern with breast roll transmission side shaft, thus realization transmission breast roll.Cooling water nozzle 4 is housed in order to the cooling breast roll body of roll in the breast roll bottom.
Claims (3)
1. the breast roll of a novel heavy and medium plate mill, it is characterized in that: comprise being positioned at each forward and backward three colored roller (1) of rolling mill roll (7), and connect axle (2) by an ac variable frequency speed regulation motor (3) driving respectively, connect axle (2) and be connected with jackshaft (8), the other end of jackshaft (8) then is connected with the arc tooth pattern with breast roll transmission side shaft; Described breast roll (1) all adopts the gate-type quick-disassembly structure to connect with frame (6).
